Yale ERP 030 TGN, ERP 035 TGN, ERP 040 TGN 2002 Parts Catalog

If you’re ordering parts for a Yale ERP 030 TGN, ERP 035 TGN, or ERP 040 TGN and you don’t have the factory parts catalog, you’re wasting your time and your customer’s money. I’ve been wrenching on lift trucks long enough to know that one wrong part number means a full day of downtime while you wait for a reorder. This 2002 Yale ERP 030 TGN, ERP 035 TGN, ERP 040 TGN 2002 Parts Catalog is the exact document the dealer uses. 314 pages of OEM exploded views, reference numbers, and part numbers keyed to your truck’s serial number. No generic aftermarket garbage that skips the options section. If you’re serious about getting it right the first time, this is what you need on the bench.

I’ve seen guys try to cross-reference part numbers from a third-party list. That ends with a caliper that doesn’t fit or a seal that leaks. This catalog eliminates that risk because it’s the original factory print from Yale Materials Corp., dated January 2002. Section tabs let you flip straight to the system you’re working on.

Think about it: you’re tearing down a brake system and you need the exact caliper assembly. Flip to Section 5 – Brake System. Page reference for the foot-operated parking brake caliper? Right there. No guessing.

Speaking of which, let’s look at what’s inside.

Electrical System: Factory Parts Breakdown

Section 2 – Electrical System covers everything from the battery connector (page 2-12) to the dash display (2-56) and control assembly for power steering on-demand. If you’re chasing a wiring issue or replacing a DC-DC converter (Section 9 – Options), you need the exact part number from this catalog. The OEM diagram shows every plug and wire harness location. Aftermarket catalogs often combine components; this one separates them by function. For example, the backup alarm shows up in two different sections (9-14 and 10-5) because it can be part of an option kit or a field conversion. Only the factory catalog catches that.

Brake System: Understanding the Caliper Assembly

Section 5 – Brake System is broken into foot-operated parking brake and electric release seat and parking brake. The caliper assembly pages give you a clear exploded view with each component numbered. You match the number to the part list, order exactly what you need. No more buying an entire brake assembly when you only need a seal kit. I’ve used this catalog to track down a specific spring in the parking brake mechanism that wasn’t listed anywhere else.

7 Sections Covering Every System from General Truck to Field Kits

The catalog is divided into 12 sections, but the core parts identification lives in Sections 1 through 8. General Truck (1) covers battery compartment, covers, decal locations, and drip plate. Drive Unit (3) gives you the complete assembly breakdown. Steering System (4) – needed that once for a worn kingpin. Hydraulic System (6) with upper and lower control valve linkages. Lifting Mechanism (7) differentiates between two-stage limited free-lift, two-stage full free-lift, and three-stage full free-lift carriages. Attachments and Header Hose Group (8) for those custom setups. Sections 9 and 10 cover Options and Field Conversion Kits – critical if the previous owner added a backup alarm or changed the battery configuration. The Numerical Index (11) lets you look up any part number fast.

Does This Parts Catalog Cover the Drive Unit?

Yes. Section 3 – Drive Unit Assembly (starting page 3-2) includes the complete drive motor, gear reduction, and axle components. You get the OEM part numbers for bearings, seals, and the drive wheel. If you’re rebuilding a drive unit on an ERP 040 TGN, you need the exact bearing race geometry. This catalog has it. The model nomenclature page (page 2) explains how to decode your truck’s serial number to ensure you’re looking at the right variant. Don’t skip that step.

Get the Right Part Numbers for Hydraulic System

Section 6 – Hydraulic System breaks down the control valve linkage into lower three and four function (6-8), upper three and four function (6-4), and upper lift and tilt (6-2). Each page has an exploded diagram with reference numbers. You match those numbers to the parts list, order from your dealer, and move on. No cross-referencing. No translation errors. That’s the difference between a factory catalog and a third-party compilation.

Why the Factory Source Matters

This is a genuine OEM document from Yale Materials Corp., P/N 524138845. Published 01/2002. Aftermarket sellers repackage scanned copies with missing pages and blurred images. This file retains the original crisp diagrams and clear type. The alphabetical index at the front lets you find any part description in seconds. I’ve used it to look up “Accelerator Pedal and Linkage” (1-18) and “Battery Roller and Retainer” (1-22) – both found in under ten seconds. When you’re billing by the hour, that speed matters.

Frequently Asked Questions

Does this catalog include wiring diagrams?

No. This is a parts catalog, not a service manual. Wiring diagrams are in the service manual. This catalog gives you part numbers for electrical components like connectors, controllers, and harnesses.

Can I use this to find part numbers for the brake caliper on an ERP 035 TGN?

Yes. Go to Section 5 – Brake System, find the caliper assembly page for foot-operated parking brake. The exploded diagram shows each part with a reference number. The parts list next to the diagram gives you the OEM part number. That’s the number you order from Yale. I’ve done it myself – took two minutes.

Access the Factory Manual and stop guessing part numbers. Keep it on your tablet or print the sections you need. Either way, you’re working with the same data the factory authorized service centers use. That’s the only way to guarantee the part you order is the part that fits.
