The Reach Stacker That Downed for Eleven Days Waiting on a Dana Part
A Tianjin container terminal ordered a Dana Repair Kit for a TE 27 transmission on a Hyster reach stacker, paid the rush surcharge, and waited eleven days for a part that arrived one serial break too new. The kit fit the input shaft and the output flange but would not seat against the transmission case because the case casting had been revised in 2008, and the kit was the post-2008 variant. The transmission in question was a 2007 build, which used the pre-2008 case. The supplier's catalog cross-reference had assumed any TE 27 could use either kit, which is true for the gaskets and seals but not for the case-mounted sub-assemblies. The terminal had to wait another week for the pre-2008 variant, during which the reach stacker was parked and three container moves per shift were rerouted to manual handlers. Eleven days of downtime, one wrong catalog assumption, and a missed container vessel.
This guide walks through the three Dana TE Series serial breaks that actually matter for parts ordering — the 1980 baseline, the 2005 TE 17 housing revision, and the 2008 TE 27 output flange revision — and how each one changes the catalog cross-reference for the Dana Repair Kit 8100262 and the surrounding Transmission Case Parts. Where the article references ZF as an alternative driveline on the same reach stacker, the comparison is in our Gearbox Brands Compared Before Ordering reference page. For procurement teams ordering parts by serial number alone, the rule is: the serial number tells you which break you are on, and the break tells you which kit you need.
Dana TE Serial Number Anatomy: Why 1980, 2005, 2008 Matter
Dana TE Series transmissions use a serial number format that has changed three times since the product line launched in 1980. Each format change coincides with a design revision that affects at least one major sub-assembly, which is why the format changes matter for parts ordering even though the serial number itself looks like a routine identifier. The three format eras are: the 1980 baseline (pre-2005), the 2005 revision (2005 to mid-2008), and the 2008 revision (mid-2008 to present). Within each era, the serial number format is consistent, and the catalog cross-reference accuracy is high. Across era boundaries, the cross-reference accuracy drops sharply unless the buyer explicitly notes which era the transmission belongs to.
The 1980 baseline format uses an 8-character serial with the first two characters being a numeric year code (80 for 1980, 95 for 1995, 04 for 2004), the next two being a plant code, and the final four being a unit sequence number. The 2005 revision extended the format to 10 characters by adding a generation code (G2 for the 2005 TE family, G3 for later TE families) between the year code and the plant code. The 2008 revision kept the 10-character format but changed the generation code (G4 for the post-2008 TE family) and shifted the position of the plant code from characters 3-4 to characters 5-6. Reading the serial number correctly therefore requires identifying the format era before doing anything else.
The three format eras map to three engineering revisions. The 1980 baseline is the original TE design with the cast iron housing, the 6-bolt input flange, and the original synchronizer spring specification. The 2005 revision introduced the lighter aluminum TE 17 housing variant and changed the input flange from 6-bolt to 8-bolt for higher torque capacity. The 2008 revision retained the aluminum housing but revised the output flange and seal carrier, and changed the synchronizer spring material from chrome-vanadium to chrome-silicon for longer fatigue life. Each revision changed at least one sub-assembly part number, which is why the catalog cross-reference for the Dana Repair Kit 8100262 has three variants — one for each format era.
Identifying Your TE Series Build Year in Under Two Minutes
The fastest field procedure for identifying which TE Series era a transmission belongs to takes under two minutes and requires only a flashlight and a clean rag. The procedure has three steps. Step one: locate the serial number plate, which is riveted to the input housing on the left side of the transmission as viewed from the bellhousing. Wipe the plate clean with the rag. Step two: read the first two characters of the serial number. If the first two characters are a numeric year code (for example "07" for 2007), the transmission is in the 1980 baseline format and the part is pre-2005. If the first two characters are numeric and the third character is "G" followed by a digit, the transmission is in the 2005 or 2008 format and you need to read the next two characters to determine which era.
Step three: confirm the generation code. G2 means the transmission is in the 2005 era (2005 to mid-2008), and G4 means the transmission is in the 2008 era (mid-2008 to present). If the serial plate is missing or unreadable, the alternative is to read the input flange bolt count: 6 bolts means pre-2005, 8 bolts means 2005 or later. The bolt count check is a 30-second procedure that resolves the era question when the serial plate is gone. For TE 27 transmissions specifically, the output flange design is the most reliable era indicator: the pre-2008 output flange has a smooth cylindrical mating face, while the post-2008 output flange has a stepped mating face with an O-ring groove. The two flanges are not interchangeable.
The procurement implication of the era identification is that the same Dana part number can refer to three physically different sub-assemblies depending on which era the transmission belongs to. The Dana Repair Kit 8100262, for example, ships in three variants: the pre-2005 kit (with the 6-bolt input flange gasket set and the original synchronizer spring), the 2005-era kit (with the 8-bolt input flange gasket set and the original synchronizer spring), and the post-2008 kit (with the 8-bolt input flange gasket set, the stepped output flange seal, and the chrome-silicon synchronizer spring). The catalog number on the outside of the box is the same. The contents are not. A procurement officer who orders 8100262 without specifying the era will receive whichever variant the warehouse ships first, which is usually the post-2008 variant because it is the most common in current stock.
The 8100262 Repair Kit: A Serial Range Compatibility Audit
The Dana Repair Kit 8100262 is a major-overhaul kit that includes the input shaft seal, the output shaft seal, the gaskets for the input housing and the output housing, the synchronizer springs, and the O-rings for the shift forks. The kit does not include friction discs or clutch plates, which are ordered separately under different part numbers. The 8100262 kit is the most cross-referenced Dana TE repair kit in the Chinese port-equipment aftermarket because it covers the most common overhaul scope and fits the most common TE 17 and TE 27 transmission variants across the Hyster RS, Kalmar DCE, and Konecranes reach stacker product lines.
The compatibility audit for 8100262 across the three serial eras shows the following pattern. For serial numbers in the 1980 baseline format (year code 80 through 04, no G code), the kit ships with the 6-bolt input flange gasket and the original chrome-vanadium synchronizer spring. For serial numbers in the 2005 era (year code 05 through 07, G2 generation code), the kit ships with the 8-bolt input flange gasket and the original chrome-vanadium synchronizer spring. For serial numbers in the 2008 era (year code 08 and later, G4 generation code), the kit ships with the 8-bolt input flange gasket, the stepped output flange seal, and the chrome-silicon synchronizer spring. The three variants are visually distinguishable by the input flange gasket shape, but they are not distinguishable by the catalog number alone.
For procurement, the safe RFQ for the Dana Repair Kit 8100262 includes the serial number, the transmission family (TE 17 or TE 27), and the explicit era declaration (pre-2005, 2005-era, or post-2008). A supplier who receives the RFQ with all three fields can ship the correct variant with 99 percent or higher accuracy. A supplier who receives the RFQ with only the catalog number will ship the most common variant, which is the post-2008 variant for the current installed base. For transmissions older than 2008, that means a 25 to 40 percent chance of receiving the wrong kit. The wrong kit is rarely discovered until the mechanic opens the box on the shop floor, which is what causes the eleven-day downtime pattern documented in Section 1.
Why the Transmission Case Casting Changed After Serial Break
The Dana TE Series transmission case casting changed twice — once in 2005 and once in 2008 — and each change revised at least one mounting interface that affects the replacement parts catalog. The 2005 case revision changed the aluminum TE 17 housing from a sand-cast to a permanent-mold casting, which improved the dimensional consistency of the bolt holes around the input flange but changed the bolt-hole pattern from 6 to 8 positions. The 6-bolt pattern parts from the pre-2005 era do not fit the 8-bolt pattern case from 2005 onward, and the catalog cross-reference for the input housing gasket had to be updated. Dana issued a formal cross-reference bulletin in 2005 listing the old 6-bolt part numbers and the new 8-bolt replacements, but the bulletin is not always accessible to aftermarket buyers.
The 2008 case revision retained the 8-bolt input pattern but revised the output flange mounting. The pre-2008 output flange used a flat-face mount with a single O-ring seal; the post-2008 output flange uses a stepped-face mount with a dual O-ring seal arrangement. The two flange designs are not interchangeable because the bolt circle is the same but the pilot diameter and the seal groove are different. The catalog entry for the output flange seal changed in 2008, and any 8100262 kit ordered for a post-2008 transmission must include the new stepped-face seal. The pre-2008 variant of the kit still ships with the flat-face seal, which does not seat against the post-2008 case.
The Transmission Case Parts catalog entries split cleanly along the era boundaries. Pre-2005 case parts are cataloged under the original Dana part numbers with no era suffix. 2005-era parts are cataloged with the "-G2" suffix on the part number. Post-2008 parts are cataloged with the "-G4" suffix. The suffix is on the box label and on the packing list, but it is not on the catalog page of most aftermarket parts databases, which is why the era declaration has to be made explicitly in the RFQ. Ningbo Beilun Lanhai Port Machinery maintains a three-variant inventory of 8100262 kits in the Beilun warehouse and ships the variant matching the era declaration on the RFQ.
Pre-2005 TE 17 vs Post-2005: Three Procurement Differences
The pre-2005 TE 17 and the post-2005 TE 17 are mechanically similar but procurement-different in three specific ways. The first is the input flange bolt pattern: 6-bolt for pre-2005, 8-bolt for post-2005. The bolt pattern difference affects the input flange gasket, the input flange seal, and the bolt set itself. A pre-2005 input flange gasket ordered for a post-2005 transmission will not seat against the case, and the leak will show up within the first 50 operating hours. The second is the synchronizer spring: pre-2005 used chrome-vanadium, post-2005 used chrome-silicon. The two springs look identical at a glance but have different fatigue life ratings, and the post-2005 spring is mandatory for any transmission that has been rebuilt with post-2005 parts. The third is the shift fork O-ring: the pre-2005 O-ring is a single-lip design, the post-2005 O-ring is a dual-lip design. The dual-lip O-ring provides better sealing at higher line pressures but is slightly larger in outer diameter, which means it does not fit the pre-2005 shift fork groove.
The procurement implication of the three differences is that a mixed inventory of pre-2005 and post-2005 parts in the same transmission leads to assembly errors that are usually caught at the shop floor but occasionally ship out as completed units. The most common mixed-inventory error is to install a post-2005 synchronizer spring in a pre-2005 transmission, which works mechanically but does not match the catalog record and may fail inspection under Dana's warranty audit. The reverse error — installing a pre-2005 spring in a post-2005 transmission — is more serious because the chrome-vanadium spring has a shorter fatigue life than the post-2005 transmission expects, and the spring can fail at half the rated service interval.
For buyers managing a fleet with both pre-2005 and post-2005 TE 17 transmissions, the practical recommendation is to stock the era-specific parts separately and to label the inventory bins with the era suffix (G2 for 2005-era, G4 for post-2008). The label overhead is small and the wrong-bin error rate drops by 80 percent or more. Lanhai's standard RFQ template for Dana TE Series parts includes the era declaration as a required field, and the standard response confirms the era suffix on the quote line before the customer confirms the order.
The 2008 TE 27 Housing Revision: What Replaced What
The 2008 TE 27 housing revision was Dana's response to two field issues reported in 2006 and 2007: an output flange fatigue crack that showed up on TE 27 transmissions operating above 2,500 hours per year in container yard service, and a seal carrier porosity issue that allowed transmission oil to leak past the output flange into the park brake assembly. The revised housing addressed both issues by adding a reinforcement rib around the output flange pilot and by changing the seal carrier from a sand-cast iron part to a machined steel part. The two changes are visible on the outside of the housing as a thicker output flange boss and a smoother seal carrier surface, but they are not visible from the input side of the transmission.
The parts that changed with the 2008 TE 27 revision are: the output flange (new flange with the stepped mating face and O-ring groove), the output flange seal (new dual-lip seal), the output flange bolt set (longer bolts to accommodate the reinforcement rib), the seal carrier (new machined steel carrier), and the seal carrier O-ring (larger cross-section to seal the smoother carrier surface). All five parts are included in the post-2008 variant of the Dana Repair Kit 8100262, plus the input housing gasket and the synchronizer springs that have been part of the kit since 1980.
The procurement question that matters for the 2008 TE 27 revision is whether the transmission in your fleet is pre-2008 or post-2008. The serial number era declaration resolves the question definitively. For fleets with mixed pre-2008 and post-2008 TE 27 transmissions, the standard practice is to order the post-2008 variant of the 8100262 kit for any transmission whose serial number is unknown or unreadable, on the basis that the post-2008 variant will retrofit into the pre-2008 transmission with one extra part (the pre-2008 output flange seal, ordered separately) while the pre-2008 variant will not retrofit into the post-2008 transmission at all. This practice reduces inventory complexity at the cost of a small per-order parts premium, which is usually the right trade-off for fleets with fewer than ten reach stackers.
Reach Stacker Gearbox Decision: ZF vs Dana Side-by-Side
For new reach stacker purchases, the choice between a ZF driveline and a Dana TE Series driveline depends on three variables: the operating duty cycle, the local service network, and the parts inventory strategy. The ZF WSK 6-speed manual and the HSW 110 PowerShift are the most common ZF configurations on Kalmar and Konecranes reach stackers; the Dana TE 17 and TE 27 are the most common Dana configurations on Hyster and older Kalmar units. The two brands use different parts catalogs, different serial number formats, and different service intervals, which means a fleet that operates both brands carries twice the parts inventory complexity but gains redundancy when one brand's parts supply is disrupted.
The operating duty cycle favors Dana TE Series for high-hour, single-shift operations in container yards where the reach stacker runs 2,500 to 4,000 hours per year. The Dana TE 17 and TE 27 transmissions are rated for continuous duty at higher torque loads than the equivalent ZF manual transmissions, and the synchronizer spring life is longer on the Dana side under high-cycle conditions. The ZF PowerShift class (HSW 110 and HSW 130) is rated for higher peak torque but requires more frequent clutch plate replacement, which is the operating cost trade-off. For port terminals running two shifts per day, the ZF PowerShift typically delivers lower per-hour operating cost despite the higher clutch replacement frequency, because the shift quality is smoother and the operator fatigue is lower.
The local service network and parts inventory strategy matter as much as the duty cycle. In the Chinese port market, ZF has a stronger authorized service network through ZF Services China and a faster parts supply chain from the Shanghai and Tianjin warehouses. Dana relies on a smaller authorized service network and a longer parts lead time from the Singapore and US warehouses, which is offset by Lanhai's Ningbo-based inventory of the most common Dana TE repair kits and case parts. For terminals that prioritize same-day parts availability, the Lanhai inventory model makes Dana TE Series operationally equivalent to ZF in lead time, which removes one of the traditional disadvantages of the Dana brand in the Chinese market.

Frequently Asked Questions
What is the Dana TE Series serial break that matters most for parts ordering?
The 2008 serial break matters most because it revised the TE 27 output flange and seal carrier, which changed the parts catalog for the Dana Repair Kit 8100262 and the surrounding transmission case parts. Pre-2008 and post-2008 TE 27 transmissions require different output flange seals, and the wrong seal ships in 25 to 40 percent of aftermarket orders if the era declaration is not included in the RFQ.
How do I identify the serial break on my Dana TE transmission?
Locate the serial plate on the input housing (left side as viewed from the bellhousing), read the first three characters: numeric year code (for example 07 for 2007) means pre-2005 format, G2 means 2005 era, G4 means post-2008 era. If the plate is missing, count the input flange bolts: 6 bolts means pre-2005, 8 bolts means 2005 or later. For TE 27 specifically, the output flange face distinguishes pre-2008 (smooth) from post-2008 (stepped with O-ring groove).
Does Dana Repair Kit 8100262 fit all TE Series transmissions?
The catalog number 8100262 applies across the TE 17 and TE 27 families, but the kit ships in three variants matching the three serial eras: pre-2005 (6-bolt input flange gasket, original synchronizer spring), 2005-era (8-bolt input flange gasket, original synchronizer spring), and post-2008 (8-bolt input flange gasket, stepped output flange seal, chrome-silicon synchronizer spring). The variant must be declared on the RFQ or the supplier ships the most common variant in stock.
What is the difference between pre-2005 and post-2005 TE 17 transmissions?
The pre-2005 TE 17 has a 6-bolt input flange and a chrome-vanadium synchronizer spring. The post-2005 TE 17 has an 8-bolt input flange and (after 2008) a chrome-silicon synchronizer spring. The input flange gasket, the input flange bolt set, and the synchronizer spring are not interchangeable between the two eras. Mixed inventory between pre-2005 and post-2005 parts leads to assembly errors and warranty audit failures.
What changed in the 2008 TE 27 housing revision?
The 2008 TE 27 revision added a reinforcement rib around the output flange pilot to address a fatigue crack issue and changed the seal carrier from sand-cast iron to machined steel to address an oil leak issue. The new housing requires a stepped output flange with a dual O-ring seal arrangement, plus longer output flange bolts to accommodate the reinforcement rib. All five changed parts are included in the post-2008 variant of the 8100262 repair kit.
Which is better for a reach stacker: ZF or Dana transmission?
For high-hour single-shift container yard operations (2,500 to 4,000 hours per year), the Dana TE 17 and TE 27 deliver longer synchronizer life and lower per-hour maintenance cost. For two-shift operations or applications requiring smoother shifting and lower operator fatigue, the ZF WSK 6 or HSW 110 PowerShift delivers better shift quality despite higher clutch plate replacement frequency. The local service network and parts inventory strategy often decide the choice as much as the duty cycle, especially in the Chinese port market.
