GEHL 142, 152 Parts Catalog

When you’re elbow-deep in an undercarriage rebuild on a GEHL 142, 152 Parts Catalog, the last thing you need is a part number that doesn’t match the bolt in your hand. I’ve seen aftermarket parts lists that send a ⅜” cap screw where a flanged lock nut belongs. That’s how you waste a morning and a customer’s patience. This is the factory manual – GEHL’s own 126-page exploded-view parts book, form number 908538. It’s the same document the dealership uses. If you’re ordering parts for a 142 or 152, this is the only source that gives you the right number the first time.

TORQUE SPECIFICATIONS: The Section You Cannot Skip

Every mini-excavator has fasteners that need a specific torque value. The manual includes a dedicated Torque Specifications section. Track roller bolts, sprocket nuts, idler bracket caps – you get the factory pound-feet numbers. No guessing. I’ve seen too many stripped threads from guys using “close enough” torque. With this book, you tighten to print. Period.

What Does the Numerical Index Do for You?

A parts catalog without a numerical index is a treasure hunt. This one has it. You find a part number on the machine, look it up in the index, and it points you to the exact page and reference number in the exploded view. That’s the difference between a 10-minute parts order and a 45-minute swear-fest. The index covers every fastener, seal, and hydraulic fitting listed in the book. Use it.

Undercarriage Breakdown for the 142 and 152

Section A covers the undercarriage. You get separate exploded views for the model 142 undercarriage and the model 152 undercarriage. They share some track tension and roller assemblies, but the frame and final drive groups differ. The manual shows you which parts interchange and which don’t. Pay attention to the track roller section – there’s a separate page for the 142 track roller vs. the 152. Order the wrong one and you’ll have a gap between the roller flange and the track chain.

126 Pages of Factory-Coded Parts

Every bolt, washer, and seal is coded with GEHL’s own abbreviation system. You’ll see “CS” for cap screw, “FLN” for flanged lock nut, “LW” for lock washer. The introduction includes the full abbreviation table. No interpretation needed. If a part number is marked with an asterisk, that means the assembly is broken down further later in the section. This manual gives you the complete tree – from main assembly down to the last cotter pin.

Order Parts the Right Way

When you call the parts counter, they need the part number, description, quantity, and your machine’s model and serial number. The manual doesn’t just give you a picture – it lists the full description and the required quantity for each reference number. That’s the difference between getting the right part and getting a box of wrong hardware. Pair this catalog with a service manual for the actual repair steps, and you’ve got everything you need.

Does this parts catalog include repair procedures for the engine?

No. This is a parts catalog, not a service manual. It lists every component with part numbers and exploded views, but it does not contain step-by-step overhaul instructions or diagnostic steps.

How do I find the torque spec for the undercarriage bolts in this manual?

The Torque Specifications section is listed in the table of contents. It gives the torque values for all standard fasteners used on the 142 and 152. Look for the heading “TORQUE SPECIFICATIONS” – it’s a dedicated section with values in pound-feet. Use those numbers every time you tighten a track roller, sprocket, or idler bolt. I always keep a grease pencil near that page because I reference it on every undercarriage job. The manual also includes a note that damaged or worn parts must be replaced with genuine Factory service parts before operating the machine – that’s safety language, not legal filler.

This Parts Catalog is the only OEM document that gives you the exact part numbers and torque specs for the GEHL 142 and 152 mini-excavators. If you need to order seals, bearings, bolts, or complete undercarriage assemblies, you cannot afford to rely on a generic cross-reference. Access the Factory Manual and keep it on your tablet or printed out in the shop – you’ll save a weekend of wrong parts every time you rebuild a track frame.
