Yale ERC 100 HG, ERC 120 HG, ERC 70 HG, ERC 80 HG 2002 Parts Catalog

If you’re hunting for the right part number on a Yale ERC 100 HG and you’re using some aftermarket diagram, you’re wasting time. I’ve been there. You end up ordering the wrong seal or a valve that doesn’t match. This 468-page factory parts catalog fixes that. It’s the same book we use in the shop when we need to identify a part down to the last O-ring. The Yale ERC 100 HG, ERC 120 HG, ERC 70 HG, ERC 80 HG 2002 Parts Catalog gives you the OEM exploded views and part numbers. You get the exact part numbers.

Yale ERC 100 HG, ERC 120 HG, ERC 70 HG, ERC 80 HG 2002 Parts Catalog – What You Get

You open this manual and you see the actual factory sections. Section 6 covers the Hydraulic System. Section 7 covers the Lifting Mechanism. The CONTROL VALVE is in Section 6, with an exploded view that shows every spring, spool, and plug. I’ve seen techs install a valve backwards because they used a generic diagram. Not with this. The manual also includes a Numerical Index in Section 11 so you can cross-reference any part number fast. For older Yale models, the Yale OS 030 BC SS 030 BC 1997 Parts Catalog OEM uses the same indexing system.

Control Valve: Exploded View and Part Numbers

The control valve section lists each part with the Yale factory number. You need the relief valve cartridge? It’s there, along with the plugs, springs, and seal kits. The exploded view shows the exact order of assembly. That matters when you’re rebuilding a valve and need to know which O-ring goes where. I’ve seen aftermarket catalogs mix up the spool sections on the ERC 120 HG. This manual keeps it straight. The electrical section (Section 2) includes wiring diagrams that reference the Local Interconnect Network (LIN) protocol for some components, but this 2002 manual covers the standard wiring here.

Mast Tilt Assembly: Page-by-Page Coverage

Mast tilt assemblies are often misordered. The MAST TILT section – part of Section 7 and also covered in the Field Conversion Kits under Section 10 – shows the tilt cylinders, brackets, and hardware. This manual covers both two-stage and three-stage full free-lift carriages. If your truck has a serial number after ECN 73815, there are alternate pages marked clearly. You’ll find the tilt cylinder rebuild kit part numbers. Don’t trust aftermarket cross-references. They’ll send you a seal kit that’s close but not right. I’ve had to redo that job twice. Use the OEM numbers from this catalog and you get the correct parts the first time. For other Yale equipment, the Yale MP, MPB 040 AC 1997 Parts Catalog Factory OEM follows the same format.

7 Major Sections Covering All Systems

The catalog is divided into 12 sections. The major ones you’ll use are: GENERAL TRUCK (section 1), ELECTRICAL SYSTEM (section 2), DRIVE UNIT (section 3), STEERING SYSTEM (section 4), BRAKE SYSTEM (section 5), HYDRAULIC SYSTEM (section 6), LIFTING MECHANISM (section 7). That’s seven. Then there are ATTACHMENTS, OPTIONS, and FIELD CONVERSION KITS. The FENDER CONVERSION kit is in section 10. The 12 VOLT LIGHTS option is also in section 10. Having all these in one 468-page book saves you from digging through service bulletins. And don’t forget section 10 with the field conversion kits. That includes the fender conversion and the 12 volt lights kit. Each kit has its own parts list so you can retrofit your truck. The index at the end helps you find any part number fast.

Does the Manual Include the 12 Volt Lights and Fender Conversion?

Yes. Section 10, Field Conversion Kits, includes both the fender conversion and 12 volt lights. The fender conversion page shows the brackets, bolts, and fender panel. The 12 volt lights kit includes the light assembly, wiring harness, and switch. If you’re adding lights to a truck that didn’t come with them, this is the parts list you need. The electrical system section (section 2) also covers the standard lighting. If you’re working on a different type of equipment, such as Supercharger Systems, you’d need a different reference – but for these Yale lift trucks, this catalog is all you need for parts identification.

Why Factory OEM Documentation Matters for Lift Truck Repairs

Aftermarket parts catalogs are often photocopies of photocopies. The pages get blurry, the part numbers are smudged. This manual is a digital scan of the original Yale print from 2002. The text is legible, the diagrams are clear. You can zoom in on the control valve detail and read the part number. I’ve had techs bring me aftermarket catalogs that show a different valve for the ERC 100 HG. That’s a waste of time. Stick with OEM. For older models, the Eaton Yale & Towne 1700 1969 Service Manual – OEM Factory Data covers the earlier equipment.

Frequently Asked Questions

Is this a genuine OEM manual?

Yes. Printed by Yale in 2002.

Does it include torque specifications for assembly?

This is a parts catalog, not a service manual. It does not list torque values. You need the Yale service manual for torque specs on components like the mast or control valve bolts. The parts catalog gives you the exact part numbers and exploded views so you can order the correct seals, bearings, and hardware. For example, the control valve section shows the entire valve assembly with each part number. That helps you get the right o-ring kit without guessing. But for installation torque, refer to the service manual. This catalog is designed for parts identification and ordering only.

What models are covered?

Yale ERC 70 HG, ERC 80 HG, ERC 100 HG, and ERC 120 HG. The manual covers these four models with a publication date of 08/2002.

Can I use this manual for repair procedures?

No. This is a parts catalog, not a repair guide. It does not contain step-by-step disassembly or reassembly procedures. You’ll need the corresponding service manual for that. However, the exploded views are very useful for understanding how components fit together. If you’re rebuilding a control valve, the parts diagram shows the stack-up order.

Don’t waste time with second-guessing. Access the Factory Manual and get the OEM data you need. Your lift truck will thank you, and so will your wallet.
