Yale GLP35, GDP35, GDP55, GLP55 2008 Parts Catalog

If you are ordering parts for a Yale GDP35 or GLP55 and you don’t have the OEM number, you are either cross-referencing aftermarket junk or calling the dealer every time. Neither works fast. This Yale GLP35, GDP35, GDP55, GLP55 2008 Parts Catalog is the factory 666‑page document that gives you the exact exploded view and part number for every nut, seal, and bracket. No reprints, no copied PDFs with blurry lines. This is the original OEM print from Yale Corp., dated 05/2008. You get the same book that goes on the parts counter at the dealership, minus the markup.

Open it to page 3 and you see the 15 major sections: General Truck, Diesel Engine (1004.42), LPG Engine (4.3L), Fuel System, Electrical, Steering, Brake, Transmission, Hydraulic, three mast types, Options, Numerical Index, and User Support. That is everything you need to locate a part from the counterweight to the throttle link. The alphabetical index on page 5 lets you go straight to the assembly—no flipping through 600 pages blind.

15 Major Sections for Complete Coverage

This catalog covers both the diesel and LPG engine variants across the GDP35, GDP55, GLP35, and GLP55 models. The diesel section (section 2) is for the 1004.42 engine—includes fan drive, cylinder block, crankshaft and piston, oil pump, manifolds, cylinder head, coolant pump, timing gear, valve cover, cooling, exhaust, and the rotary exhauster. The LPG section (section 3) covers the 4.3L engine with its own exhaust manifolds, cooling, fan drive, engine mounts, and cylinder components. Each assembly is drawn out with callouts and a table of part numbers. You do not guess; you look at the drawing, find the number, and order it.

Does This Catalog Cover Both Diesel and LPG Engines?

Yes. Section 2 is the diesel engine (1004.42), section 3 is the LPG engine (4.3L). They are separate because the parts differ—cylinder heads, manifolds, fuel systems. If you are working on a GLP35 with an LPG engine, you use section 3. If it is a GDP55 diesel, you use section 2. The fuel system section (section 4) covers both open‑loop and closed‑loop LPG systems, plus low‑pressure and injection systems for diesel. You also get the carburetor, lock‑off valve, converter, and governor for LPG. It is all in one book, arranged by engine type and then by system.

Get the Right Part Number the First Time

Every time I see a guy order a water separator for a GDP55 and get the wrong one because he used a generic parts site, I think of this catalog. On page 4.44 (in the fuel system section) you see the water separator assembly with its own part number. You match the serial number break—the catalog notes production breaks like “⇒S/N C813A-01588” and “D/B 07/2001⇒”. Those marks tell you which parts fit your truck. Ignore them and you will get a seal that does not seat. That is why OEM documentation matters. Yale GLP20-35VX GDP20-35VX 2006 Parts Catalog covers the VX series if you need a different model range.

Suspension Seat: What’s Included

The General Truck section (section 1) covers the full suspension seat in two sheets. You get the cushion, the armrests, the mounting bracket, and the seat belt anchor. If your operator complains about a rough ride and you need to replace the suspension seat base, you go to that page, find the part number, and order it. No calling the dealer to ask which bracket you need. The same section also covers the non‑suspension seat, rear screens, floor plates, sound reduction, overhead guard, and all the labels. That is 14 pages of truck‑level parts that most aftermarket catalogs skip. Yale GDP/GLP35-55 Parts Catalog 2008 is the same product you are reading about.

Source Authenticity: OEM vs. Aftermarket

I have seen aftermarket parts catalogs that just photocopy a worn‑out original and sell it as a PDF. The images are dark, the part numbers are smudged, and the serial number breaks are missing. This manual is the actual factory scan from the 2008 Yale print. The page headers say “Yale QL PARTS MANUAL” with the part number 524150875. Every drawing is crisp enough to read the callout numbers. You are not going to waste 20 minutes cross‑referencing a blurred line. The difference between an OEM part number and a third‑party guess is the difference between a 10‑minute repair and a 2‑hour headache. Yale OS 030 BC SS 030 BC 1997 Parts Catalog OEM is another factory example for older machines.

What You Need to Know About the Model Nomenclature

Page 2 of the catalog shows the model nomenclature chart. It tells you how to decode the truck model code—power type, tire, mast—so you pick the right section. The complete truck model and serial number are stamped on the nameplate. If you skip that step, you end up in the wrong assembly page. The catalog also includes a numerical index (section 14) where you can look up a part number directly if you already have one. That is a fast way to find where a part belongs in the assembly. Automotive Industry Overview is about the broader industry, but this catalog is strictly hands‑on.

One more thing: the user support information in section 15 includes contacts and part ordering details. If you need to call Yale with a question about a superseded part, you have the reference. The catalog is 666 pages for a reason—it leaves nothing out. Automotive Industry Overview is informational, but this manual is the tool you actually use on the bench.

Frequently Asked Questions

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. For torque specs, get the corresponding service manual.

How do I identify which parts fit my specific truck model?

Use the model nomenclature on page 2 to decode your truck model code (e.g., GDP35LJ, GLP55MJ). Then match your serial number to the production breaks listed in each assembly page. The catalog marks changes with “⇒S/N” and “D/B” dates. For example, the alternator mount for GDP35LJ has a production break at D/B 07/2001 and another at S/N C813A-02227Y. If your truck serial number falls after that break, you order the later alternator mount. Always verify your truck’s serial number from the nameplate before ordering. This catalog gives you the exact part number for your serial number range—no guesswork.

You can stop hunting for part numbers. This is the original OEM catalog that Yale parts departments use. Access the Factory Manual and get the right part the first time.
