Yale GLP16, GLP18, GLP20, GDP16, GDP18 2008 Parts Catalog

If you are wrenching on a Yale GLP16, GLP18, GLP20, GDP16, or GDP18, you already know that aftermarket parts diagrams are a gamble. I have seen techs order the wrong bearing because some third-party catalog listed the wrong serial number break. That is why I only reach for the factory binder when I am pulling parts on these trucks. This 2008 Yale GLP16, GLP18, GLP20, GDP16, GDP18 2008 Parts Catalog is the real deal – 592 pages of OEM exploded views, part numbers, and the torque values that keep the head gaskets from leaking.

Let me be clear about one thing right up front: this is a parts catalog, not a service manual. It won’t walk you through a rebuild step-by-step. What it does give you is the exact diagram of every assembly – from the engine cover to the mast forks – so you can order the correct part the first time. I have wasted enough billable hours chasing parts that don’t fit. This catalog stops that.

Engine Coverage: Diesel and LPG

The catalog splits the engine sections by fuel type. Section 2 covers the 2.5L diesel engine (GDP AF models). Section 3 covers the 1.5L LPG engine for GP/GLP BF models. Section 4 covers the 2.0L LPG engine for GP/GLP AF models. Each section includes the cylinder block, cylinder head, crankshaft and piston, camshaft and valves, timing gear cover and oil sump, oil pump, manifolds, fuel system, cooling, and electrical system. You get the serial number breaks – for example, the flywheel and torque converter for the diesel engine is listed two ways: A810B-2577 and earlier, and A810B-2578 and later. If you don’t check that, you’ll order the wrong flexplate. I have seen it happen.

Torque specs are not listed in a separate table, but they appear in the assembly notes for each component. For the cylinder head, you will find the tightening sequence and torque values printed right on the exploded view page. Need to know the oil pump torque? Flip to the oil pump section. It is all there, but you have to read the fine print. This is a factory document, not a Chilton’s summary. Expect the density.

Fuel System: LPG and Diesel Separate

Section 5 is the fuel system. Yale grouped the LPG and diesel fuel components into separate subsections. The LPG tank, converter, governor, carburetor, and throttle linkage are all there with part numbers. The diesel fuel system includes the injection pump, nozzle holder, fuel filter, and fuel tank and lines. Page numbers are not printed on every page (Yale used a system of section and page numbers), but the alphabetical index at the front of the manual helps you locate the exact part. I have used this index to find a throttle linkage pin in under 30 seconds. That is faster than calling the dealer.

One thing I appreciate: the catalog includes the governor and carburetor for both GP and GLP models, with identification by code letter. If you have an old LPG converter with a “K” code, they have a dedicated page for that. No guessing – you match the letter and order the rebuild kit. This is the kind of detail that saves you a return trip to the parts counter.

Suspension and General Truck Sections

Section 1 covers the general truck: frame and floorplates, engine cover, counterweight, seat assembly (including suspension seat and non-suspension seat), fender, hood latch, noise reduction covers, and overhead guard. The suspension seat is broken down into three date codes: D/B 01/2000, full suspension seat from 01/2000 onward, and non-suspension seat from 01/2000 onward. If you are replacing seat foam or a seat belt bracket, you need to know which type you have. This catalog tells you exactly which part number fits.

The torque values for the frame bolts and counterweight are listed on the exploded views. I have seen a counterweight bolt back out because a tech used a “close enough” torque from a generic chart. Don’t be that guy. The manual says 150 ft-lbs? You dial in 150, not 145, not 155. Use a calibrated torque wrench. I keep a Snap-on torque wrench dedicated to these jobs.

Electrical, Steering, Brake, and Transmission

Sections 6 through 9 cover the electrical system, steering, brakes, and transmission. The electrical system is split by model – GP/GLP AF, GP/GLP BF, and GDP AF. The wire harness chassis diagram is included. The steering section covers the column, trail axle, orbitrol unit, and steering cylinder (with date breaks). The brake section includes the pedal linkage, brake assembly with serial number breaks, brake lines, master cylinder, park brake lever, and shift lever. The transmission section covers the housing and gears with multiple serial number ranges. If you are rebuilding a transmission, you need the correct thrust washer thickness. The part numbers are listed, but you must cross-reference the serial number on the nameplate. This catalog gives you the OEM part number – you then order that from Yale or an aftermarket supplier who knows how to cross-reference.

Hydraulic system (Section 10), mast sections (11-13), forks and load backrest (14), options (15), and a numerical index (16) round out the catalog. The numerical index is a lifesaver when you have a part in hand with a number but don’t know which section it belongs to. Look it up in the index, and it tells you the section and page. I have used that index to find a hydraulic fitting that had been superseded three times.

Who Needs This Manual?

This catalog is for anyone who owns or services a Yale GLP16, GLP18, GLP20, GDP16, or GDP18. If you are a DIY mechanic in a home garage, you will appreciate the exploded views – they show you how everything goes together. If you run a shop, this catalog cuts down parts ordering time. If you are a fleet manager, you need this to verify that your parts guy is ordering the correct components. The 2008 edition covers AF and BF series, so check your model year. This is not a reprint of a generic aftermarket catalog – it is a scanned OEM doc from Yale Europe Materials Handling Limited, P/N 504250718, dated 07/2008. The original file is 592 pages, and it is the same binder that Yale dealers use.

I have seen too many guys trust a $20 aftermarket parts manual and end up with a piston that doesn’t fit. This factory catalog is the only way to be sure. Automotive Industry Overview – that is a whole other topic, but the point is: OEM documentation is the standard. Automotive Industry Overview

Does this manual include torque specs for the cylinder head?

Yes. The torque values and tightening sequence are printed on the cylinder head exploded view page in Section 2 (diesel) or Section 4 (LPG 2.0L). You need to read the fine print next to the part callouts. No separate table – it’s integrated into the diagram.

Can I use this catalog for a 2005 Yale GLP16?

Only if your truck is AF or BF series. The 2008 catalog covers those series. Check your nameplate for the model code and serial number. If your truck has a date code before 2008, some parts may have been superseded. The catalog includes serial number breaks, so you can verify compatibility. For older trucks, look for the 2007 edition.

Access the Factory Manual and stop guessing. This is the same OEM document that Yale dealers use. No aftermarket abbreviations, no reprints. You get the exact part numbers and torque data that will keep your forklift running. Put it on your tablet or print the pages you need – either way, you are working from the source.
