Clark-hurth 292, 292B 1990 Parts Catalog

You pull a scraper into the bay, serial number worn off the tag, and the customer wants a brake rebuild by Friday. Without a factory parts catalog, you are guessing which seal kit fits the 292 versus the 292B. Clark-hurth built these elevating scrapers with enough difference between the two models that aftermarket cross-references will cost you time and money. This 1990 Clark-hurth 292, 292B Parts Catalog is the original OEM document – 156 pages of exploded views, part numbers, and assembly callouts that Hancock Division printed in June 1990. No reprints, no third-party scans. You get the same book a dealer parts counter used.

Brake Assembly and Air Chamber – Page 136 and 109

Brake work on a scraper that weighs 30,000 pounds is not a guessing game. The catalog dedicates a full spread to BRAKE ASSEMBLY (page 136) and AIR CHAMBER (page 109). Both sections include exploded diagrams with every spring, diaphragm, and return bolt listed by part number. You need the correct pivot pin for the 292B? It is there. The air chamber mounting gasket? Numbered. Aftermarket catalogs often merge these into one generic brake group, but Clark-hurth kept them separate because the 292 and 292B used different chamber stroke lengths.

Air system schematics for the scraper (page 106) and tractor (page 104) are also broken out. If you have an air leak in the scraper circuit, this tells you which line goes to which valve bank. OEM torque for the chamber flange bolts is not listed here – that is in the service manual – but the catalog gives you the correct part for replacement.

Cooling System and Engine Group – Page 6

Overheating a Clark-hurth engine because you slapped in a generic radiator cap? Page 6 covers the COOLING SYSTEM with the OEM fan shroud, coolant lines, and the radiator part number. The ENGINE section on the same page shows the flywheel housing, front cover, and mounting brackets. If you need the water pump gasket for a 292, the catalog lists it separately from the 292B because the pump drive changed.

Valve train parts are grouped later under HYDRAULIC COMPONENTS (Valve, Relief – pages 57, 57A; Valve, Scraper Control – pages 52, 54, 54A). The relief valve for the lift circuit uses a different shim stack than the steering valve. Aftermarket listings call them interchangeable. They are not. This catalog shows the shim part numbers and spring rates for each.

Transmission and Torque Converter – Factory Disassembly

The transmission section alone runs from page 80 to page 95. You get clutch assemblies for No. 1 through No. 5 (pages 86-88), shaft location (page 80), and the Low-Low Shifter Valve (page 95). Torque converter pages 76 and 78 show the stator, impeller, and turbine as separate exploded views. If you rebuild a converter without this catalog, you might order the wrong bearing carrier for a 292B. The output drive line (page 103) and input drive line (page 102) are separated – input uses a different yoke than output.

Hydraulic circuits are mapped per function: Ejection Circuit, Tractor (pages 26, 28, 30); Steering Circuit (pages 20, 22, 24); Elevator Circuit, Scraper (pages 42, 44, 46). Each circuit shows the cylinder, motor, and valve locations with part numbers. The elevator motor (pages 63-65) and pump (pages 60-62) are broken down into seal kits and housings.

Who Needs This Catalog and Why

If you are a shop owner or a DIY landowner maintaining a Clark-hurth 292 or 292B elevating scraper, this catalog saves you from ordering blind. Beginners should not attempt a full transmission teardown without the factory parts breakdown – the clutch pack order matters. Professionals will use it to verify superseded part numbers. The catalog also covers accessories and options (pages 148-150) and decals (page 151) for restoration work.

Source Authenticity: OEM vs Aftermarket

This is a genuine Clark Equipment Company – Hancock Division publication, printed in the USA, June 1990, Manual No. 4070. It replaces the earlier 292/292B Parts Manual No. 1012. Aftermarket PDFs often re-scan the same pages with missing foldouts or blurred part numbers. The original book had 156 pages of clean line drawings and part tables. Every entry comes from the factory – not a third-party compiler guessing which bolt goes where.

Does this catalog include torque specs for the brake assembly?

No. This is a parts catalog, not a service manual. Torque values are in the factory service manual. This catalog gives you the correct part numbers for the brake shoes, chambers, and hardware so you can order the right kit.

Can I use this catalog to identify parts for a 292B that has been modified with aftermarket hydraulics?

If the scraper still uses the Clark-hurth original hydraulic components (pump, valve, cylinder), the part numbers in this catalog will match. Aftermarket substitutions like a different elevator motor or a non-OEM control valve will not appear. You need to verify the serial number and compare the existing component to the exploded views. The catalog lists the OEM steering valve (pages 18, 18A) and lift-ejection control valve (pages 52, 54, 54A) – if your machine still has those, the part numbers are accurate. If someone swapped in a generic valve bank, you are on your own.

Stop wasting time with aftermarket cross-reference guides that treat every 292 like a 292B. This OEM parts catalog gives you the factory breakdown for both models. Access the Factory Manual and get back to turning wrenches.
