GEHL 303 Parts Catalog – Factory OEM Document

I’ve been turning wrenches for 28 years, and I can tell you the difference between a job that goes smooth and one that eats your lunch is often the piece of paper you’re reading. If you’re ordering parts for a GEHL 303 Parts Catalog compact excavator without the factory document, you’re gambling with your time and your wallet. This isn’t a reprint from some online file dump – it’s the original 110-page GEHL factory parts catalog, form number 909786, printed in the U.S.A. You get the same illustrations and part numbers the dealer uses.

What You Actually Get – 110 Pages of Factory Parts Data

Open this catalog and you’ll find exploded-view diagrams for every major assembly. The table of contents lists undercarriage (page 8), track tensioning (page 9), track-supporting roller (page 10), track roller (page 11), dozer blade (page 12), uppercarriage (page 13), lubrication block (page 14), rear wall (page 15), counterweight (page 16), valve cover (page 17), lifting arm (page 18), short dipper arm (page 19), long dipper arm (page 20), and connecting sections. Each section gives you the reference number, description, and quantity. You won’t find that level of detail in a generic aftermarket catalog.

Track Undercarriage: Rollers, Tensioning, and Dozer Blade

The tracks take the abuse on a compact excavator. This manual breaks down the undercarriage into individual rollers – supporting roller, track roller – plus the track tensioning mechanism. If you’ve ever tried to adjust track tension without the proper part numbers, you know the headache of mismatched rollers. The dozer blade section shows the blade assembly, mounting brackets, and hydraulic cylinder parts. Use the numerical index to cross-reference any part number back to its diagram.

Torque Specifications: Why the Inside Back Cover Matters

Standard attaching hardware torque values are printed on the inside back cover. Metric torque values in the illustrations are given in Newton-meters; you multiply by 0.738 to get foot-pounds. I’ve seen too many bolts snapped because somebody used a generic chart. This catalog gives you the factory spec. That’s not a suggestion – it’s the difference between a seal that holds and a leak that costs you a weekend. For background on why diesel engines need specific bolt torques, read this Wikipedia article on diesel engines.

Don’t skip that step.

Alphabetical and Numerical Indexes – Two Ways to Find a Part

The catalog includes both an alphabetical index and a numerical index. If you have a part number, the numerical index points you to the exact page. If you only know the part name (say “sprocket” or “seal”), the alphabetical index gets you there. That’s how you avoid ordering the wrong piece for your 303. The indexes are meant for fast lookup when the machine is down and the clock is ticking.

GEHL 303 Parts Catalog vs Aftermarket – Accuracy You Can Count On

Aftermarket parts catalogs often use generic illustrations and skip the revision levels. GEHL updates these drawings as they change suppliers or improve designs. This factory copy includes the exact reference numbers tied to the serial number tag on your cabin front panel. Don’t trust a third-party PDF that might have been scanned from an old copy. Stick with the source. For operator-level specs, pair this with the GEHL 253 303 353 373 2011 Operators Manual – Factory Specs.

FAQ

Does this manual include torque values for all fasteners?

Standard torque values are on the inside back cover. Metric values are in the illustrations. That covers most hardware in the machine.

How do I identify which parts are for the short dipper arm versus the long dipper arm?

The catalog separates them on pages 19 (short) and 20 (long). Each exploded view lists the specific part numbers for that arm assembly. The dipper arm sections include the cylinder pins, bushings, and seals. If your machine has the long dipper, you order from page 20. The reference numbers are different – don’t mix them up. Also check the serial number tag to confirm which arm your unit shipped with from the factory. The manual says “Right” and “left” are from the operator’s seat. That same orientation applies to the arm. Order the correct kit using the index first, then verify against the illustration.

None of this matters if you don’t have the catalog in your hand when the part counter asks for a number. Access the Factory Manual from AutoRepairManuals and keep it on your tablet or printed out. You’ll know you’re ordering the right seal, the right bolt, the right everything – because the factory wrote it down. That’s the difference.
