GEHL 8435, 8500 Parts Catalog – What You Get With a Factory Print

I’ve been turning wrenches since before some of you were born. Nothing burns my ass faster than ordering a part from a third-party parts list, bolting it on, and finding out the thread pitch is wrong or the shoulder length is off by three millimeters. That’s why when I see a GEHL 8435, 8500 Parts Catalog sitting on the bench, I know the job is going to go right. This is the same binder the dealer techs used. 76 pages of exploded views, exact part numbers, and torque values that were written by the people who built the machine. Not some intern in a warehouse scanning a PDF.

If you’re working on a 8435 or 8500 mixer feeder – including the truck-mounted variants – you need the OEM breakdown. Aftermarket catalogs will give you a generic bolt size and hope you guess the grade. That’s how you end up with a sheared auger drive bolt at 4 p.m. on Friday. This manual puts the factory spec right in your hand. Decal locations, hitchjack components, weighbars, chaincase – it’s all in here. And the torque specs are on the inside back cover, where you can find them without flipping through fifty pages.

Torque Specs: Inside Back Cover

Every fastener in this catalog references a standard hardware torque value printed on the inside back cover. Not “tighten securely.” Not a chart from a 1984 Snap-On poster. Factory foot-pound values for Grade 5 cap screws, plow bolts, flange lock nuts – all of it. When you see a hexagon symbol next to a reference number in the exploded view, that number is the torque in foot-pounds. If you skip that step, you’re the one who gets to drill out a broken bolt later. I’ve done it. Don’t be that guy.

Decal Locations: Pages 2-7

Decals seem like a small thing until you have a safety inspector walk through and you can’t prove the warning labels are original. Pages 2 through 7 in this Parts Catalog show exactly where every decal goes on the 8435 and 8500 frames. Right side, left side, behind the discharge gate – it’s all mapped. If you’re restoring a unit or replacing worn decals, this is the only reference you should trust.

Auger Drive and Chaincase: Pages 14-21

Auger bearings, auger drives, chaincase internals – this is where the heavy work happens. The catalog breaks down the chaincase mounting, cover, and auger drive cover on separate pages. Part numbers for the chaincase housing, sprockets, bearings, and seals are all listed with quantities. You can order exactly what you need instead of buying a whole assembly. Page 18 gives you the chaincase breakdown; page 22 covers the mounting and cover. That saves you time and phone calls to the parts counter.

Truck Mounted Mixer Feeder Parts: Pages 51-64

The truck-mounted version shares a lot of components with the trailer model, but the driveline and hydraulic pump setups are different. Pages 51 through 64 cover the TM drive line, chaincase, hydraulics and controls, weighbars, scale, pump components, and accessories like fenders, mud flaps, and light kits. If you’re converting or repairing a truck-mounted unit, you need this section. Don’t assume the trailer parts fit – check the reference numbers.

3 Reasons to Use OEM Parts Catalogs

First: part number accuracy. Aftermarket catalogs often renumber parts or omit supersessions. This catalog uses the original GEHL part numbers. Second: exploded views show how everything fits together before you order. Third: torque specs are included – not a separate book. That’s three reasons. I could give you ten, but if you need more convincing, you probably haven’t been burned yet.

Does This Manual Cover the Discharge Conveyor?

Yes. The one-piece discharge conveyor is detailed on pages 26-29, and the two-piece version is on pages 30-33. Part numbers for conveyor chains, slats, and drive components are listed. Discharge door hydraulics are on pages 24-25. If you’re replacing a conveyor chain, you’ll find the exact link pitch and pin size from the factory. No guessing.

This manual also includes an alphabetical index on page 66 and a numerical index from page 67 to 72. If you know the part number but not the name, look it up in the numerical index. If you know the name, hit the alphabetical index. That’s how a real parts book works.

FAQ

Will this catalog fit my GEHL 8435 with a serial number starting with 5000?

The catalog covers model 8435 and 8500 mixer feeders, including truck-mounted units. The serial number plate is on the left side of the main frame. Part numbers are listed with the original factory reference numbers. If your serial number falls within the production range of this manual, you’re covered. No guarantee on pre-production prototypes.

Are torque specifications included for every bolt?

Standard hardware torque values are on the inside back cover. Bolts with specific torque requirements have a hexagon symbol with the foot-pound value next to the reference number in the exploded view.

Does this include the truck-mounted hydraulics?

Yes. Pages 58-59 cover TM hydraulics and controls. Pump components are on page 61.

What about the tire sizes?

Tire sizes are not listed individually; GEHL policy prohibits direct tire sales. Wheel set part numbers are provided, and tire size information is called out in the wheel set description so you can buy tires locally.
