GEHL RL20DX Parts Catalog – OEM Factory Specs for Your Rigid Loader

I’m Mike Callahan. 28 years turning wrenches, ASE Master, shop owner in San Antonio. If you’ve ever ordered a part for a GEHL RL20DX from a generic aftermarket “cross-reference” list and ended up with a bracket that bolts to nothing, you know the pain I’m talking about. That’s why I push every tech and DIY owner I meet toward the real factory Parts Catalog – not a scanned copy someone’s cousin made in his basement. This 24-page PDF from GEHL is the only document that gives you the correct part numbers, exploded view layouts, and GEHL RL20DX Parts Catalog torque specs right off the inside back cover. No rounding errors. No “close enough” fasteners. You order what the loader actually left the factory with.

The manual opens with a straightforward introduction that spells out how to read reference numbers, what grade hardware you’re dealing with (Cap Screws are Grade 5 unless stated otherwise), and the abbreviations you’ll see – CS, HN, FHCS. Page 1 is blank, page 2 has the real start. The Table of Contents on page 3 lists Decal Locations (pages 2-3), Frame/Seat/Wheel & Boom on page 5, Frame breakdown on pages 6-7, and the Engine section on pages 8-9. If you’ve ever tried to find the right decal for an RL20DX, that first section saves you an hour of hunting through bins.

Frame and Boom Assembly: What Page 5 Covers

Page 5 pulls together the frame, seat, wheel, and boom in one exploded view. That might sound simple, but watch any seasoned mechanic – they know the boom mounting points on these rigid loaders take a beating. The part numbers call out bushings, pins, and the specific capscrews with their torque values. The inside back cover of this Parts Catalog lists standard attaching hardware torque specs. I’ve seen guys guess at those numbers and snap bolts inside the loader frame. Use the factory data. It’s printed on the back cover – not buried in some appendix.

Engine Section 8–9: Are You Ordering the Right Parts?

The engine section spans pages 8 and 9. It doesn’t show a full teardown procedure – this is a parts catalog, not a service manual – but it does list every component you need if you’re rebuilding or replacing. Cylinder head gasket, injector lines, fuel pump mounts – all with GEHL part numbers. If you’re hunting for a specific seal or gasket, the numerical index at the back cross‑references every part number. That index runs alphabetically and numerically. Skip that step and you’ll be flipping back and forth three times before lunch. Refer to this Wikipedia article on diesel engines for general engine theory if that’s your interest, but for parts ordering, stick to the factory pages.

Torque Specifications – Inside Back Cover Data

Look inside the rear cover of this 24-page Parts Catalog. There’s a torque table for standard attaching hardware – capscrews, nuts, the lot. It’s not a full engine torque chart, but for the bolts referenced in the exploded views (frame mounts, boom pins, wheel bolts), that table is the only number you should trust. I’ve seen aftermarket catalogs that list generic torque values, and they’re wrong for GEHL’s Grade 5 hardware. This original document tells you the ft‑lbs for each fastener grade. I keep a copy on my tablet in the shop for every RL20DX that rolls in.

How to Use the Numerical and Alphabetical Indexes

Two indexes are printed after the Table of Contents: Numerical Index and Alphabetical Index. Alphabetical sorts by part description – “Bolt, Hex” – and points you to the page. Numerical sorts by the part number itself. If you already have a part number from a scrap tag, go straight to the numerical index. If you’re describing what you need (“fuel filter head”), use the alphabetical side. This manual doesn’t waste space explaining how indexes work – it just prints them. That’s how factory docs should be. Dense and usable. Don’t expect hand‑holding. Expect accuracy.

Who Should Buy This GEHL RL20DX Parts Catalog?

If you own a GEHL RL20DX rigid loader and plan to keep it running past the first major repair, buy this. If you’re a shop that services these loaders in a fleet, buy one copy per bay. The 24 pages cover decal placements, frame, boom, seat, wheels, and engine – exactly what you need to order the correct parts. It’s not a repair manual; it doesn’t tell you how to rebuild a hydraulic cylinder. But without the part numbers and torque specs from this catalog, you’re gambling with your machine. If you work on other GEHL models, check the related manuals: GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog, GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs, and GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual all follow the same dense, correct format.

OEM vs Aftermarket: Why This Parts Catalog Wins

I’ve tested aftermarket parts catalogs against the original GEHL print for the RL20DX. Aftermarket ones mix part numbers across model years, omit the inside‑cover torque table, and sometimes swap illustrations. The factory document – this exact scan – is printed from GEHL’s own file (Form No. 908183). It replaces 908037. That means it’s the current revision. The only place you’ll get guaranteed correct data is from a source like AutoRepairManuals that stores the original OEM PDF. Don’t accept a third‑party re‑hash. You’ll waste money on returns. You’ll waste time waiting for the right bolt. And if you’re billing labor, time is money. I’m not saying aftermarket catalogs are useless – some are okay for reference – but for the RL20DX, I won’t use anything except this factory file.

FAQ

Does this Parts Catalog include repair steps like engine removal?

No. This is a parts catalog – it lists part numbers, exploded views, and fastener torque specs. For repair procedures you need the corresponding service manual. But you still need this catalog to order the correct parts before you start the job.

Can I use this manual to find the torque for the wheel lug nuts on my RL20DX?

Yes. The inside back cover includes standard attaching hardware torque values. Wheel bolts are standard hex cap screws, so the table covers them. If the RL20DX uses a specialty fastener, the exploded view will note it. Otherwise, the table gives the correct ft‑lbs for each grade and diameter.

If you’re tired of playing “guess the part number” and you want the same documentation I use in my shop, get the real GEHL RL20DX Parts Catalog from AutoRepairManuals. The factory file is 24 pages, clear, and includes the torque data you need. this Wikipedia article on diesel engines gives you a background on the powerplant, but for the parts and numbers, you need the factory print. Access the Factory Manual and start ordering parts with confidence tomorrow morning.
