Yale GP, GTP, GLP, GDP Parts Catalog – Factory Parts Identification

You ever order a part for a Yale lift truck and get the wrong one? That happens when you rely on aftermarket cross-reference lists that skip serial number splits or interchange updates. This factory parts catalog – the Yale GP, GTP, GLP, GDP Parts Catalog – gives you the exact part numbers Yale used when those trucks were built. 236 pages of reference numbers, part numbers, descriptions, quantities, and remarks. No guesswork, no third-party interpretations. You get the OEM list, period.

That’s what a real parts catalog does. It tells you which part fits which model and which serial number range. The YALE manual covers the GP (gasoline), GTP (dual fuel), GLP (LPG), and GDP (diesel) in 15, 18, 20AK, 20RK/TK, 25RK/TK, 30TK, and 35TK configurations. Engine codes 92 (4TNE92 2.7L diesel) and 98 (4TNE98 3.3L diesel) are listed. The table of contents calls it “DETAILED OF SPARE PARTS” – a straight-up parts list with the columns you need: Reference number, Part No., Description, Quantity, and Remarks.

Reading the Parts List: Reference, Part No., Description, Quantity, Remarks

Page 1 lays out the system. Reference numbers correspond to exploded-view drawings (the assembly parts aren’t marked in principle – you get the reference, then look up the part number). Part numbers are stated in figures. Description includes the minimum necessary specification and the category (like which engine or model). Quantity is given as a number; items marked AR mean “as required” – you order what you need up to the asterisk (*) maximum. Remarks column tells you the applying model, engine indication, and any successive changes (that’s the “Exchange of parts” section). Abbreviations like NSS (Not Supplied Separately), NA (Not Available), W/, W/O, and INCL. make it compact. “Right hand” and “Left hand” are always relative to the forward motion of the forklift – that matters when you’re ordering a steering cylinder or a brake line.

Exchange of Parts – Why Serial Numbers Are Critical

Yale changed part numbers over time. Early types and late types might not be interchangeable. If you grab a part number from an online database that doesn’t track the change point, you get a box that doesn’t fit. This manual includes the exchange notes – it tells you which serial number range uses the early part and which uses the late part. When ordering, you must specify the serial number. Page 2 of the manual states: “Note that the parts numbers are subject to change without notice. When parts should be replaced and if there is no interchangeability, the numbers for parts of ‘late’ and ‘early’ types will be indicated.” That’s the difference between a shop that gets it right the first time and one that has to re-order.

3 Reasons to Use the Factory Parts Catalog

One: You get the actual part numbers Yale assigned – not a generic list based on brand or capacity. Two: The exchange-of-parts section prevents misfires when serial numbers cross revision thresholds. Three: The quantity column uses AR and asterisk limits so you don’t over-order or under-order fasteners and seals. Aftermarket catalogs often omit those details. If you’ve ever had a job stopped because a “universal” part didn’t match the engine code, you know why this matters. Automotive Industry Overview shows that OEM documentation remains the standard for liability and accuracy in heavy equipment. This catalog is that standard.

Does This Catalog Cover Your Yale Model?

It covers GP/GTP/GLP/GDP15,18,20AK, GP/GTP/GLP/GDP20,25RK/TK, and GP/GTP/GLP/GDP30,35TK. Engine codes 92 (2.7L diesel) and 98 (3.3L diesel) are included. If you have a different model, check the Yale Detailed of Spare Parts Index”>related index or the Yale Detailed List of Spare Parts for GP/GTP/GDP/20AK/25/30/35RK/TK”>detailed list for specific variants. Also see Yale Detailed of Spare Parts GP/GTP/GLP/GDP/GD”>the GD-series catalog if you have a different fuel variant. This is a parts catalog – not a service manual. It does not contain torque specs or assembly procedures. But if you need to find a part number for a cylinder head gasket, a lift chain, or a hydraulic fitting, this is the single source of truth.

FAQ

Is this the same as the service repair manual?

No. This is the parts catalog. It lists part numbers and quantities, not repair steps.

How do I know which part number to use if my serial number is between two change points?

The exchange-of-parts section on page 2 of the manual shows early and late type numbers with the corresponding serial number break. You find your truck’s serial plate, compare it to the range listed, and order the part number in that block. If there is no interchangeability, only one number applies. The catalog also notes when a part is “NA” (not available separately) or “NSS” – you would then order the next higher assembly. Always include the serial number when ordering from a dealer; this manual gives you the logic so you can double-check the dealer’s cross-reference.

You need the right part number the first time because downtime on a Yale lift costs you billable hours and customer trust. This factory parts catalog puts the exact numbers in your hands. Access the Factory Manual and keep it in your shop – alongside the service manual – so you never guess a part number again.
