If you are working on a Yale GLP20, GDP20, GDP25, GDP30, or GLP25 forklift from the 2006 model year, you already know how much of a headache it is ordering parts without factory documentation. Aftermarket cross-reference lists get it wrong. eBay listings give you a part number that fits nothing. Without the OEM parts catalog, you are guessing. This is the Yale GLP20, GDP20, GDP25, GDP30, GLP25 2006 Parts Catalog – 922 pages of verified part numbers straight from the manufacturer. Page 2 shows the model nomenclature so you can match your truck’s serial number to the correct assembly groups.

What This 2006 Yale Parts Catalog Covers

The manual is split into 17 sections. General Truck (section 1) covers the frame, floorplates, hood, counterweight, and all seat variations – non-suspension, semi-suspension, and full suspension. The suspension sections include date-break notes like “D/B 01/2000” so you order the right seat support. Sections 2, 3, and 4 break down the engines: 2.5L and 3.0L diesel, 2.0L and 2.2L LPG, and a separate 3.0L LPG engine. Then you have fuel system, electrical, steering, brakes, transmission, hydraulics, and a full set of mast sections. Each section has exploded diagrams with part numbers and serial number ranges. This is not a service manual – it will not tell you how to rebuild a cylinder head. But it tells you exactly which cylinder head to order.

Trust Factory Parts Data Over Aftermarket Cross-References

I have seen too many techs order a “compatible” part from an aftermarket catalog only to find it two millimeters off. That is not a problem with this manual. Every part number here was assigned by Yale. The manual includes updates and changes marked with date breaks and serial number breaks. For example, under “Seat Full Suspension Sheet 1 of 2 D/B 01/2000” – those date breaks are critical. If you ignore them, you might order a suspension seat frame that does not bolt to your truck’s cab. Use OEM data. It saves you the return shipping cost and the downtime. I have seen this mistake twice in the past year; each time the technician lost half a day waiting for the right part. Invest in the factory manual and avoid that headache.

Get it right from the start.

922 Pages of Specific Part Numbers

The alphabetical index at the front lets you look up any component by name – “Air cleaner”, “Camshaft”, “Counterweight”. The numerical index at the back lets you cross-reference a part number you already have. For example, if you pull a part off the truck and see a number stamped on it, flip to the numerical index and find which page lists that number. That is faster than any online search. The PDF is searchable, but having the index makes it even faster.

How to Find the Right Suspension Components

Finding the correct suspension components requires careful attention to serial number breaks. The suspension coverage includes seat suspension options: non-suspension, semi-suspension, and full suspension. There are multiple sheets for full suspension with different date breaks. Your truck’s serial number tells you which sheet to use. Do not skip this step. Installing the wrong suspension seat can cause the seat to detach during operation. That is a safety issue. The manual also lists the seat belts, armrests, and mounting hardware. If you need to replace a worn-out seat, this is the only reliable source for the correct part numbers.

Diesel vs. LPG: Engine Sections Explained

Section 2 covers the 2.5L and 3.0L diesel engines (XA/HA series). Section 3 covers the 2.0L and 2.2L LPG engines (FE/F2 series). Section 4 covers the 3.0L LPG engine with EPA compliance. Each engine section includes cylinder block, cylinder head, crankshaft and piston, camshaft and valves, timing gear cover, oil sump, fuel system, water pump, and electrical system. There are also separate sub-sections for different emission levels and serial number ranges. If you are working on a 2004–2005 series engine, you need the specific pages for that series. The manual organizes it all.

Does this parts catalog include torque specs for assembly?

No, it’s a parts catalog. Use the service manual for torque values.

How do I find the correct part number for my truck’s serial number?

Use the serial number breaks listed in each section. For example, under “Radiator and Hoses” there are multiple sub-sections covering different serial number ranges. Match your truck’s serial number to the correct page. The alphabetical index also helps you locate the right section quickly.

Are the part numbers in this manual still current?

Part numbers can supersede. This manual is from 2006, so some parts may have been updated. However, you can use the part numbers as a starting point and check with your Yale dealer for current numbers. The manual includes many parts that are still manufactured.

What does “D/B 01/2000” mean in the suspension sections?

D/B stands for “date break” – the change point in production. 01/2000 indicates the change occurred in January 2000. So if your truck was built before that date, use one set of parts; after that date, use another. Reading these breaks correctly is critical to ordering the right suspension components. Get it wrong and the seat won’t mount properly, which is a safety hazard. Always verify your truck’s build date or serial number against these breaks.
