GEHL 520, 522 Parts Catalog – OEM Factory Parts Breakdown

You’ve got a GEHL 520, 522 Parts Catalog in your hands, or you should. That rake with the bent tine arm or a blown wheel bearing isn’t going to fix itself. Without the right part numbers, you’re burning time cross-referencing aftermarket lists that don’t match the factory hardware. This is the original GEHL Agriculture manual—32 pages of exploded-view drawings, part descriptions, and torque callouts that a dealer uses. Not a copy. Not a third-party scan. The real print.

Decal Locations: Where the Serial Number Hides (Pages 2-3)

Page 2 tells you exactly where to find the model and serial number decal: the backside of the left side width adjustment wheel pivot frame member. Right and left are determined standing at the rear facing forward. If you skip that step, you’re ordering parts for the wrong generation of rake. The manual also explains the abbreviations used in the parts list—CB, CS, FCS, FLN, all of them. That’s the difference between a Grade 5 cap screw and a flanged lock nut. Don’t guess.

Front Drawbar & Scissors Assembly (Pages 4-5)

This section covers the drawbar hitch and scissor linkage that connects your tractor to the rake. Each part has a reference number that ties to the part number, description, and quantity. If you need a new pivot pin or bushing, the illustration shows exactly how it goes together. No guesswork on orientation. The manual also flags which fasteners require torque—look for the hexagon symbol with a foot-pound number next to the reference number on the exploded view.

Hydraulics Section (Pages 14-17)

Pages 14 through 17 cover the hydraulic system—cylinders, hoses, fittings, and the valve if equipped. The catalog shows the correct hose length and fitting style. Use the wrong O-ring boss fitting and you’ll be chasing a leak that wastes half a day. The hydraulic section also calls out replacement wheel sets on page 18-19 because GEHL policy prohibits selling tires directly. Tire size is listed with the wheel set so you can buy the right tire locally. That’s factory procedure, not a parts counter guess.

Torque Specs on the Inside Back Cover

Flipping the manual to the inside back cover gives you standard hardware torque values in foot-pounds. Grade 5 cap screws, Grade B nuts—all the baseline numbers you need when reassembling any section of the rake. But pay attention: some specific fasteners in the exploded views have a hexagon symbol with a torque value printed next to them. Those override the standard table. I’ve seen technicians strip a flange bolt because they used the generic spec instead of the one called out in the drawing. Don’t be that guy. Cross-check every torque value against the symbol if it appears.

Options & Accessories: Windrow Adjustment Kit (Pages 22-23)

If your 520 or 522 has a windrow adjustment kit or center wheel kit (pages 24-25), those parts are listed separately with their own exploded views. The safety chain kit is on page 21. These aren’t afterthoughts—they’re factory-documented options that bolt right up to the base rake. The part numbers in these sections supersede any generic cross-reference you’ll find online. Trust the book, not the forum post.

Audience Fit: Who Needs This Manual?

If you own a GEHL 520 or 522 finger wheel rake and you turn your own wrenches—even if you only replace broken tines or repack wheel bearings—you need this catalog. Dealers use it. Shop foremen use it. Don’t let a parts counter clerk sell you a universal bushing that doesn’t fit the pivot bore. The 32-page format is small enough to keep in the tractor toolbox or scan into your phone. For professional mechanics billing by the hour, this catalog eliminates the “is this the right part?” phone call.

Source Validity: OEM vs. Aftermarket Documentation

This is the factory GEHL Parts Manual, Form No. 909874, replacing 906157. It’s not a reprint from a third-party reseller that crops the drawings and omits the torque page. The inside front cover has the introduction and ordering instructions straight from GEHL Agriculture. Aftermarket catalogs often substitute “generic” hardware numbers that don’t match the original Grade 5 or Grade B specifications. I’ve seen side frames that wouldn’t align because a carriage bolt was one thread pitch off. If you want the part to fit the first time, buy the OEM document.

For deeper background on fastener grades and torque theory, check this Wikipedia article on diesel engines for relevant bolted joint principles—though the rake itself isn’t an engine, the torque concepts are the same. And if you’re working on other GEHL equipment, these related manuals will save you the same headaches: 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.

Frequently Asked Questions

Does this catalog include repair procedures or service intervals?

No. This is a parts catalog for ordering replacement parts, not a service or repair manual. It contains exploded views and part numbers only.

What torque values does the manual provide, and where are they located?

Standard attaching hardware torque specifications are printed on the inside back cover in foot-pounds for Grade 5 cap screws and Grade B nuts. Additionally, in the exploded-view parts list on certain pages, a number inside a hexagon symbol indicates the specific torque required in foot-pounds for that particular fastener installation. You must check both the standard table and any hexagon callout in the drawing to ensure you apply the correct value. If a hexagon appears next to a reference number, that torque overrides the generic table. The manual explicitly states on page 2 that items shown without reference numbers are for reference only and not available for purchase, so ignore those when ordering.

Access the Factory Manual—the PDF of this OEM parts catalog—and keep it in your shop tablet or printed in the tractor cab. Every time you need a replacement spindle, a flanged cap screw, or a hydraulic fitting, you’ll have the genuine part number and the correct torque spec. That’s the difference between a job that takes 20 minutes and a job that eats a whole afternoon because you ordered the wrong cotter pin.
