Yale GLP16, GLP18, GDP16, GDP18, GDP20 2008 Parts Catalog

If you’ve ever spent a Saturday morning holding a bolt that doesn’t fit while staring at a part number from a disreputable aftermarket list, you already know the value of this catalog. I’m Mike Callahan, and I’ve been turning wrenches for 28 years. This 2008 Yale GLP16, GLP18, GDP16, GDP18, GDP20 Parts Catalog is the original factory document—not a scan, not a re-packaged afterimage. It’s 608 pages of exploded views, call-outs, and the exact revision splits that hit Yale’s service network in 2008.

You want to order a cylinder head gasket for a Yanmar 2.6L diesel in your GDP18? This catalog shows you the S/N split—C810B02776E and earlier versus C810B02777E and later. Two different part numbers. Get it right the first time because the lift doesn’t stop on a Sunday.

What Does a Factory Parts Catalog Give You?

Unlike a service manual that tells you how to remove a part, this catalog tells you which part to buy. It breaks down the entire truck into 17 sections, from General Truck (hood, floorplates, counterweight, overhead guard) all the way through Options and a Numerical Index. Need a cab window wiper system? That’s under General Truck. Need the fuel injection lines for the diesel? Turn to Section 4, Fuel System. Every part number is keyed to the illustration directly above it—no cross-referencing to a separate index unless you want the numeric lookup.

For example, Section 3 covers the LPG engine (Mazda 2.0L) and includes separate parts for flywheel and housing by S/N break, plus the entire carburetor and delay valve. Section 5 is Electrical System, covering the chassis wiring, impact sensor, alternator mounting, and the power distribution module.

Section Breakdown: From General Truck to User Support

The table of contents lists 17 major sections, each with its own tabbed page. The first section alone—General Truck—covers 30+ subsystems including the full range of seats: non‑suspension seat without electronic controls, semi‑suspension seat with and without electronics, full suspension seat with and without electronic controls, full suspension swivel seat, and even the full suspension seat with limited back tilt (9/2006 onward). That’s nine different seat variants, each with its own part illustration and breakdown. If your operator complains about ride comfort, you can find the correct seat base, damper, or cushion in the catalog rather than measuring old bolt holes with a caliper.

Section 6 (Steering System) and Section 7 (Brake System) are standard fare, but they include the original Yale part numbers—not aftermarket equivalents that may or may not match. Section 8 covers the transmission, Section 9 the hydraulic system, and Sections 10–12 handle all three mast types: two‑stage limited free‑lift, three‑stage full free‑lift, and two‑stage full free‑lift. Forks, load backrest, and mast installation are in Section 13.

608 Pages of OEM Part Numbers

That’s right: 608 pages. Each page is a high‑resolution scan of the factory print, not a re‑typed list. The original file is identical to what a Yale dealer had on their shelf in 2008. Every part number is the OEM number stamped on the casting or sticker. I’ve seen shops burn an hour cross‑referencing a part from a third‑party site only to get a box with the wrong thread pitch. This catalog eliminates that. It also includes a Numerical Index (Section 16) so that if you have a part number from the old part, you can look it up alphabetically and find which illustration it belongs to.

Real‑world use case: You’re rebuilding the mast on a GDP20 with a three‑stage full free‑lift. Section 11 lists every roller, seal, and retention clip. The mast illustrations show the hose routing and the load dampening accumulator (see page 15‑12). You need the part number for the main lift cylinder? It’s in Section 9. No guesswork.

Why Aftermarket Part Catalogs Miss the Mark

Aftermarket parts books often combine multiple years into one vague diagram. They might show a “typical” GLP16 that actually shares parts with a completely different series. This catalog is specific to the 2008 models only, with serial number splits clearly listed in parentheses like (→ S/N C810B01963D). If you try to use a 2006 catalog, you’ll get the wrong air cleaner system or a different exhaust without catalytic converter routing. The 2008 revision incorporates changes such as the electronic throttle linkage (diesel) and the updated LPG tank bracket swing‑out with fabric strap that changed three times between 2006 and 2007. You need the right year.

For background on why factory documentation matters in the Automotive Industry Overview, consider that every OEM part number is traceable to a specific engineering change. This catalog gives you that traceability. If you want a broader overview of the industry, you can read Automotive Industry Overview on Wikipedia.

Frequently Asked Questions

Does this catalog include part numbers for the Yanmar 2.6L diesel engine?

Yes. Section 2 covers the entire engine: mounting, fan, cooling system (with two S/N breaks), exhaust, manifolds, flywheel, gear housing, oil pan, cylinder head, camshaft, crankshaft and pistons, cylinder block, water pump, and lubrication system. All OEM part numbers are listed.

Can I use this catalog to find parts for a GLP18 built after 2008?

This catalog is specifically for 2008 model year trucks. Yale made many small revisions year to year. For example, the cooling system splits by S/N C810B02776E, and the LPG tank bracket changed three times between 2006 and 2007. If your truck is a 2009 or later, you need the corresponding catalog. However, many mechanical parts (like engine internals) may carry forward—check the S/N break in each section.

How many pages is this catalog?

608 pages.

What about seat parts? I see “suspension” in the TOC.

Yes. Suspension seats are covered under General Truck. There are nine variants: non‑suspension, semi‑suspension, full suspension, and swivel versions, some with limited back tilt introduced after 9/2006. Each has its own parts list with cushions, armrests, mounting brackets, and electronic control components. If you need the seat base for a full suspension seat with limited back tilt, that part number is in this catalog.

I’ve used enough third‑party catalogs to know they waste your time. This is the real thing—OEM, 608 pages, 2008 Yale parts manual for the GLP16, GLP18, GDP16, GDP18, and GDP20. You can Access the Factory Manual from our site today and get back to turning wrenches instead of digging through forums.
