Yale GDP35LJ, GDP55LJ, GLP35MJ, GLP55MJ 2008 Parts Catalog – OEM Factory Data

You call the dealership parts counter for a cylinder head gasket for a GDP35LJ. They read back a part number that doesn’t match what you pulled off the old motor. Or worse – the aftermarket “equivalent” swells up inside six months and you’re pulling the head again on your own dime. That’s what happens when you work off a third-party parts list. I’ve been torquing heads since before some of you were born, and I’ve seen more wrecked lift trucks from wrong parts than from bad driving. The only fix is the factory Yale GDP35LJ, GDP55LJ, GLP35MJ, GLP55MJ 2008 Parts Catalog – 668 pages of OEM exploded views, part numbers, and supersession data straight out of the Yale engineering department. No guesses. No “cross-reference that probably fits.”

Diesel Engine (1004.42) – Parts Breakdown

Section 2 of this catalog covers the 1004.42 diesel motor used across the GDP35LJ, GDP40LJ, GDP45MJ, GDP50MJ, and GDP55MJ. You get every fastener for the cylinder block (two different D/B variations – note the date codes on page 5 of the keyword index to check your build), the oil pan and pump assembly, the water pump with its two revision levels, and even the vacuum device bracket that most aftermarket books skip entirely. Each sub-section lists the exact part numbers for the fan drive, alternator bracket, exhaust manifold, and valve cover. If your lift truck was built between 07/2008 and a later revision, the catalog marks the change points so you order the right piece the first time.

LPG Motor (4.3L) – GLP35LJ and GLP55MJ Coverage

Running LP gas? Sections 3 and 4 split the GLP35LJ, GLP40LJ, GLP45MJ, GLP50MJ, GLP55MJ into two fuel system architectures – open-loop and closed-loop. The catalog gives you the vaporizer part numbers for both designs, including the serial number break at C813A-01935Y and C813A-01936Y (see page xiv for how to read your serial number). You also get the three-way catalytic converter exhaust layouts for low-emission models, plus the specific LPG tank mounting options – fixed or swing-out. Aftermarket catalogs often lump all LP tanks together; this one separates them by frame cutout and strap part number.

OEM Documentation – Why It Beats the Aftermarket

Every page in this catalog was printed by Yale Corp in 08/2008, part number 524150877. The model code system on page 2 explains how to decode your forklift’s fuel type, tire type, and mast type from the nameplate. The keyword index starting on page 5 lets you look up any assembly by name – from “Auspuff 3-Wege Katalysator” to “Zylinderkopf.” I’ve used aftermarket parts catalogs that list the wrong oil filter for a GDP55LJ because they copied from an earlier year. This one lists the filter separately for GDP vs GLP, and even gives the serial number ranges where the water pump changed. That level of detail is why you don’t trust a generic PDF from a third-party seller. Automotive Industry Overview might give you general forklift history, but when you need a fuel pump part number for a GDP55LJ, you need the factory book.

Navigating the 668 Pages

The catalog is divided into 15 main sections: general (hood, counterweight, seat), diesel engine, LPG engine, fuel system, electrical system, steering, brakes, transmission, hydraulic system, two‑stage free‑lift mast, three‑stage full‑free mast, two‑stage full‑free mast, options, part number index, and customer information. Each section has its own thumb‑tab indicator on the page edge – flip the book back to the colored tab to jump to that section. The part number index at the back (section 14) lists every OEM number in numerical order, cross‑referenced to the illustration page where it appears. If you’re hunting for a specific gasket or seal, check the index first, then turn to the exploded view to verify the quantity and any included hardware.

FAQ – Parts Catalog Questions

Does this catalog cover the GLP40LJ and GLP50MJ?

Yes – the GLP35LJ, GLP40LJ, GLP45MJ, GLP50MJ, and GLP55MJ are all included in the LPG engine and fuel system sections. Check the model code on your nameplate to confirm which fuel system variant you have.

What’s the difference between a parts catalog and a service manual?

A parts catalog gives you the factory part numbers and exploded views. A service manual gives you torque specs, removal procedures, and troubleshooting. You need both if you plan to rebuild a GDP55LJ transmission.

How do I find the part number for a Zylinderkopf (cylinder head) on a GDP35LJ?

Go to section 2 (Diesel Motor), find the “Zylinderkopf GDP35LJ…” subheading. The illustration shows the head, valves, springs, and retainers with callout numbers. Cross‑reference those numbers to the adjacent part‑number table. If your serial number falls under D/B 07/2008, use the part number listed in the first column; later revisions have a separate column. Page 5 of the keyword index also directs you directly to the correct page number for cylinder head.

Is this a digital access?

Yes – this is a factory PDF scanned from the original 2008 print. You access it immediately after purchase.

You’ve got a GDP55LJ sitting on the lot with a cracked oil pan and you need the drain plug gasket by tomorrow morning. Or you’re rebuilding a GLP55MJ and want to order the correct injector kit for the closed‑loop system. Don’t waste time with aftermarket catalogs that guess at the part number. Access the Factory Manual and get the exact OEM numbers Yale stamped on the original release.
