GEHL 342, 362 Parts Catalog – What You Get

If you are turning wrenches on a GEHL 342 or 362 mini-excavator, you need more than a generic drawing. You need the actual factory Parts Catalog – the same book that sat on the dealer’s parts counter. This is it. 126 pages of exploded views, part numbers, and torque specs that came from Gehl Construction. Not a third-party reprint, not a scan that lost half the numbers. Original OEM file, straight from the source.

Mini-excavator undercarriages eat themselves if you skip track tension or torque track roller bolts wrong. I have seen techs ruin a $2,000 roller because they used a generic torque chart. This catalog gives you the exact fastener and the exact spec. No guesswork.

Undercarriage Breakdown: Model 342 vs 362

Section A of this catalog splits the undercarriage parts for each model. Pages 6 and 7 cover the 342; pages 8 and 9 handle the 362. If you are replacing a sprocket or idler, you cannot swap parts between models without checking the part number. The catalog lists every washer and bolt. The track tension procedure on page 10 applies to both models – but the parts inside the tensioner are different. Pay attention to the model callout.

Torque Specifications – Factory Data Only

Some aftermarket books list torque values as “tighten to spec” without a number. This catalog has a dedicated torque specifications section that lists each fastener type – cap screw, flanged lock nut, carriage bolt – with their required torque in foot-pounds. If you need the torque for the track roller mounting bolts, it is listed. Do not use a generic chart; use these numbers. Torque is critical on equipment that vibrates all day. Loose fasteners crack housings.

Numerical Index: Find Any Part in Seconds

After the table of contents, there is a numerical index that cross-references every part number to the page and exploded view. If you have a part number from a broken component, flip to the index, find the page, and see it in the assembly drawing. This saves time compared to flipping through every section. I use it when a customer brings in a part with only a number stamped into the steel.

Reading Exploded Views and the Abbreviation Table

The catalog uses reference numbers with asterisks to indicate sub-assemblies listed later. Page 2 includes the full abbreviation table – AR (as required), FLN (flanged lock nut), CS (cap screw). Learn these abbreviations before you order parts. I have watched guys order a “cap screw” when they needed a “flanged cap screw” and then blame the catalog. Read the damn key.

Which Tools and Parts Do You Need Before Starting?

Before you tear down the undercarriage, get the factory parts in hand. The catalog lists every seal, bearing, and fastener. For track tension adjustment, you need a grease gun with the correct adapter. For final drive disassembly, you need a puller set. I recommend checking the exploded view, writing down the required part numbers, and ordering from a Gehl dealer. Using aftermarket seals that are half the thickness causes leaks inside a week.

Does this catalog include the torque for the track roller bolts?

Yes, the torque specifications section lists the exact values.

How do I find the right part number if I do not have the old part?

Start with the model and serial number from the plate on the lower left front of the cabin (driver’s perspective). Then use the numerical index to search by assembly name, or flip through the undercarriage section and match the exploded view to your machine. If the drawing shows a reference number with an asterisk, go to the later page in that section for the individual parts. Always double-check the description – some parts look identical but have different internal diameters. I keep a set of digital calipers on the bench when I order.

Stop guessing with aftermarket diagrams that miss half the bolts. Get the real factory parts breakdown. Download the Factory Manual now and keep this 126-page catalog on your tablet or workbench. Every time you pull a cotter pin or torque a cap screw, you will have the right spec in front of you.
