GEHL 602 2009 Parts Catalog – The Only OEM Parts Reference for Your Compact Excavator

You are looking at the GEHL 602 2009 Parts Catalog – the only OEM document that gives you the exact part numbers and fastener specs for this compact excavator. I have seen too many jobs go sideways because a tech ordered the wrong seal or used a bolt that looked right but wasn’t. This factory catalog, 172 pages thick, starts at serial number AB00473 and includes the torque values you need to keep that undercarriage tight. No aftermarket reproduction – this is the original Gehl publication.

GEHL 602 2009 Parts Catalog: What You Get in 172 Pages

Every exploded view in this catalog comes from Gehl’s factory drawings. The table of contents lists every section, and you get both an alphabetical index (A–H and I–V) and a numerical index. That means you can find a part by name or by number in seconds. The catalog covers the 602 model beginning serial number AB00473, with clear serial number break notations so you order the correct revision. Torque specifications are printed on the inside back cover with metric values in Newton-meters – multiply by 0.738 for foot-pounds. Standard attaching hardware torque values are also shown.

Torque Specifications: Why This Manual Has Them Right

Torque is not a suggestion. This catalog lists standard cap screw, nut, and bolt torque values for Grade 8.8 hardware (cadmium or zinc plated). If you are tightening a bolt on the final drive or the boom cylinder, you need those numbers. The torque table inside the back cover matches what Gehl used on the assembly line. Ignoring those specs means snapped bolts or joint failures – I have seen both.

Alphabetical and Numerical Indexes Save Time

Flip to the back, and you hit the alphabetical index pages. Need a hydraulic filter? Look under “F” and get the reference number. Then cross-reference with the numerical index to land on the exact exploded view page. This is not a generic aftermarket catalog where you hunt through PDFs for twenty minutes. The structure is no-nonsense, exactly what a working shop expects.

Does This Parts Catalog Cover Your Serial Number Range?

The catalog starts at serial number AB00473. Inside, you will see notes like “(SN 999 and before)” or “(SN 1000–2000)” or “(SN 2001 and up including 1996)”. Those tell you which parts apply to which machine. If your 602 has a serial number earlier than AB00473, you need a different revision. This is common with Gehl – they update parts as they refine the design. Always verify your serial number before ordering anything.

7 Reasons to Use OEM Parts Documentation

1. You get the exact part number – no cross-referencing from third-party lists.
2. Fastener descriptions use standard abbreviations (CS, HN, LW) that match what your supplier stocks.
3. Seal kits are flagged with a small bag icon in the exploded views – no guessing.
4. Torque values are factory-verified for every threaded joint.
5. The alphabetical index lets you search by component name even if you do not know the part number.
6. Serial number breaks prevent ordering a part that will not fit your machine.
7. Original Gehl copyright and revision control means you are not working from a scanned copy of an old photocopy.

If you are maintaining a fleet of compact excavators, pair this catalog with the GEHL 502, 602, 652 Service Manual – Factory Specs for Compact Excavators for the repair procedures. The service manual gives you the how-to; this catalog gives you the what-to-order. For background on the diesel engine used in these machines, you can read this Wikipedia article on diesel engines.

Understand the Fastener Abbreviations Before You Order

The catalog uses a set of abbreviations listed on page 2: CS for cap screw, HN for hex nut, LW for lock washer, FHCS for flat head cap screw, and so on. Do not skip that page. If you order a “cap screw” when the illustration calls for a carriage bolt (CB), the head will not seat correctly. The abbreviations table is there for a reason – use it. Also note that unless otherwise specified, all hardware is Grade 8.8.

For related parts documentation, see GEHL 602 Compact Excavator Parts Catalog which covers the same model with additional revision data. Another option is the GEHL 602 Parts Catalog if you need a separate copy for the shop floor.

Is this the same as the service manual?

No. This is the parts catalog for ordering components, not repair procedures.

How do I know which parts fit my specific unit?

The catalog includes serial number breaks for every major assembly. For example, a page may note “(SN 1000–2000 except 1996)” or “(SN 999 and up including 997)”. That tells you exactly which parts apply to your serial number range. The alphabetical index then guides you to the correct exploded view. If your serial number falls outside the range shown (beginning AB00473), you need a different revision. Always cross-check your machine’s serial number tag (located on the front cabin panel) against the catalog’s serial number range before ordering.

Access the Factory Manual now and keep a copy in your shop tablet – you will reference it every time you rebuild an undercarriage or replace a hydraulic valve. Having the correct part number before you call the dealer saves you delays and returned shipments.
