Yale ERC35HG, ERC40HG, ERC45HG, ERC55HG 2008 Parts Catalog

If you have ever ordered a part for a forklift from a generic parts list and ended up with the wrong seal, wrong bearing, or wrong wiring harness, you know the time and money that burns. That stops here. This is the 2008 Yale ERC35HG, ERC40HG, ERC45HG, ERC55HG OEM Parts Catalog – 286 pages of factory-sourced part numbers, exploded diagrams, and assembly breakdowns that let you order the exact component the first time. No guessing. No returns. Just the right piece to put that lift truck back in service.

What You Get Inside This 286-Page Parts Catalog

Fourteen major sections break down the entire truck. Section 1 – General Truck covers counterweights, overhead guards (curved and straight leg), floor plates, hoods, and the Suspension seat choices – both non-suspension and full suspension (sheets 1 and 2). Need the battery spacer? Page is right there. Section 2 – Electrical System dives into control panels for 36/48V and 72/80V, contactor panels, power steering on-demand, and detailed wire harness sheets for main control, lights, dash panel, and brake switch. Each harness has its own drawing with connector callouts. You can identify a pin or a wire color without pulling the whole loom.

Section 3 – Drive Unit gives you the drive axle, transmission, traction motor, drive tire and wheel. Section 4 – Steering System covers steer axle, cylinder, motor and pump, gear pump, column, steer pump, shift lever, and steer tire and wheel. Section 5 – Brake System shows the park brake lever actuated linkage, brake assembly, master cylinder, accelerator, and foot directional control. Section 6 – Hydraulic System lists the single pump and motor, supply/return, hydraulic motor, pump 29 cc, filter, plumbing to control valve, hand levers, control valves (three and four function), mast installation, and tilt cylinder. Every line in these sections is keyed to the factory part number.

Finding the Right Part for Your ERC35HG or ERC55HG?

That is the whole point. The catalog includes three mast families – two stage limited free-lift (section 7), three stage full free-lift (section 8), and two stage full free-lift (section 9). Each mast has separate sections for outer, inner, main lift, lift cylinders (note the ERC35-40 HG vs ERC45-55 HG cylinder differences in section 7), and carriages. Section 10 – Header Hose Group covers hose routing for each mast height. Section 11 – Forks, Load Backrest, and Mast Installation includes Class III and Class IV forks and optional load backrest extensions. Section 12 – Options covers DC converter, accumulator, drive lights, strobe light, LED backup and brake lights. If your truck came with extras, the part numbers are here.

You also get a numerical index (section 13) to cross-reference any part number back to its exploded view. And section 14 – User Support Information. This catalog is built for one job: telling you exactly which bolt, gasket, or motor goes where. That is all.

3 Reasons to Source Parts from the Factory Catalog

First, the part numbers are genuine Yale numbers. A generic aftermarket catalog often substitutes or groups parts incorrectly because they don’t account for production changes or trim levels. This manual separates sheets for main control harnesses built before and after August 2005 – a detail no third-party list catches. Second, the exploded views show how assemblies stack together. You can see alignment of the steer axle kingpins or the order of spacers in the brake linkage. Third, you avoid the 30% restocking fee when you order the wrong item. The effort you spend looking up the number in this catalog pays for itself on the first correct order.

Electrical System and Suspension Coverage

Two areas where parts get mixed up all the time: Electrical components and Suspension seats. The catalog dedicates multiple sheets to the control panel – separate pages for 36/48 volt and 72/80 volt systems. Each wire harness sheet (e.g., main control sheets 1 and 2, lights, dash panel, brake switch) includes the specific connectors and wire routing. If you are swapping the line contactor or the top switch inside the steer column, you have the direct part reference. On the suspension side, the full suspension seat comes in two sheets – one for the seat structure, one for the cushion and armrest parts. Non-suspension seat is also broken out. No need to measure bolt holes and hope it fits.

Know Your Model Nomenclature Before Ordering

The manual includes a model nomenclature page (page 2 of the PDF) that tells you how to decode your truck’s model code. The truck’s complete model and serial number are stamped on the nameplate. You need that serial number to narrow down the right assembly page. For example, the main lift cylinder for two stage limited free-lift is listed separately for ERC 35-40 HG and ERC 45-55 HG – same type, different stroke. If you skip the serial number lookup, you risk a mismatch. Write the serial number down before you crack the catalog. It will save you a return trip to the parts counter.

Parts Catalog vs Aftermarket: Why It Matters

I have seen aftermarket catalogs that list a “universal” brake master cylinder for a whole forklift line. Then the bore diameter is wrong or the pushrod length is off. The factory catalog lists the exact master cylinder part number for the ERC35HG vs the ERC55HG – they are not always the same. The same goes for steer tires: the steer tire and wheel page lists the rim offset and tire size specifically for these models. Aftermarket sources often reuse data from older Yale models like the Yale OS 030 BC SS 030 BC 1997 Parts Catalog OEM or Yale MP, MPB 040 AC 1997 Parts Catalog Factory OEM, which might not match these 2008 builds. And even older manuals like the Eaton Yale & Towne 1700 1969 Service Manual – OEM Factory Data are useful for older trucks, but not for these ERC HG series. Stick with the manual written for your year and model.

For a broader understanding of how industrial vehicles are classified and regulated, you can check the Automotive Industry Overview. And if you are working in a shop that handles multiple forklift brands, the Automotive Industry Overview context helps you see why OEM documentation matters across the whole sector.

Does this parts catalog include torque specifications or service procedures?

No. This is strictly a parts identification manual – exploded views, part numbers, and quantity lists. For torque specs, fluid capacities, and repair steps you need the corresponding service manual (sold separately).

How do I identify which mast type is installed on my forklift?

Look at the truck nameplate for the model code. The manual’s model nomenclature table (page 2) decodes the mast suffix. If you see “FL” in the mast code it is full free-lift; “LFL” is limited free-lift. You can also look at the lift cylinder configuration – full free-lift has two cylinders (main lift plus free-lift cylinder), limited free-lift has only a main lift cylinder. The catalog then directs you to sections 7, 8, or 9 based on that. If your truck has an overhead guard with curved legs vs straight legs, that also changes the part numbers for the guard itself. Check the guard type against the illustrations in section 1 – page numbers are listed in the alphabetical index.

You need the right parts to keep that Yale earning its keep on the warehouse floor. That means using the same catalog the dealer parts counter pulls up. Access the Factory Manual and put the wrong‑part guesswork behind you for good.
