GEHL 1162, 1165 Parts Catalog – Factory Exploded Views and Torque Specs

If you’ve ever ordered the wrong gear for a cutterbar because some aftermarket website had a blurred picture, you know the pain. This is the real deal: OEM GEHL 1162, 1165 Parts Catalog, 24 pages of factory exploded views and torque specs printed on the inside back cover. I’m Mike Callahan, and I’ve been pulling wrenches long enough to tell you that parts catalogs from GEHL itself are the only way to guarantee you’re buying the correct bolt, bearing, or shim. The disc mower model and serial number plate sits on the left side of the main frame near the drawbar anchor point — that number is your key to this catalog.

24 Pages of Factory-Ordered Content

This catalog isn’t a repair manual — it’s a parts identification book. But if you’re rebuilding a cutterbar or replacing a drive belt, you need the exact reference numbers. The Table of Contents starts on page 1 and routes you to Decal Locations (pages 2–3), 3-Point Frame (page 4), Main Frame (page 5), Lift System (pages 6–7), Belt Drive & Input Shaft (page 8), Angle Gearbox (page 9), and then the cutterbar gears separated by model — Cutterbar Gears (1162) on page 10, Cutterbar Gears (1165) on page 11. Each exploded view shows every nut, washer, and seal with a reference number that ties to the parts list.

Torque Values: Why the Inside Back Cover Matters

Right inside the back cover, GEHL prints standard hardware torque specifications in foot-pounds. This is not a generic chart — it’s for Grade 5 cap screws and Grade B hex nuts, the hardware used throughout these mowers. In the exploded views, a torque value inside a hexagon tells you exactly how tight that fastener needs to be. Skip that and you’ll either strip threads or leave a joint loose enough to vibrate apart. I’ve seen guys guess on the cutterbar disc bolts and then wonder why the blade comes off at 540 RPM.

Cutting System Exploded Views – 1162 vs 1165

Two separate pages for the cutterbar gears: 1162 on page 10, 1165 on page 11. These are not the same machine. The 1165 has a wider cut, different gear counts, and different part numbers for the discs and wear plates. If you mix them up, you’re buying parts that won’t mesh. The catalog also covers Cutterbar Shoes, Guards & Wear Plates (page 12), Cutterbar Discs (page 13), and Cutterbar Hardware (page 14). Every bolt, lock washer, and key is listed with its GEHL part number. You also get the Protective Cover & Frame (page 15) and Outer Swath Wheel & Inner Swath Board (page 16).

Does This Parts Catalog Cover the Hydraulics?

No. This is a parts catalog, not a service manual. It doesn’t give hydraulic schematics or repair procedures. But it does cover the Lift System (pages 6–7) with exploded views of cylinder mounts, clevises, and pins.

Why Factory Documentation Beats Aftermarket Lists

Aftermarket parts catalogs often reuse generic drawings or omit the torque callouts. This GEHL print shows the exact fastener grade (Grade 5, zinc plated) and includes notes like “hexagon nuts for Grade 5 screws are Grade B.” The abbreviation table on page 2 decodes every fastener type — CS for cap screw, FLN for flanged lock nut, SHCS for socket head cap screw. If you’re ordering a part for the PTO (page 17), you need the correct spline count and length. Aftermarket sites don’t give you that. This catalog does. If you want to understand the engineering behind these drivelines, this Wikipedia article on diesel engines covers the power source, but for the mower itself, nothing beats factory paper.

FAQ

Can I use this parts catalog to repair the cutterbar?

No. This catalog identifies parts and their locations. You still need a service manual for removal, shimming, and reassembly procedures. Also see the Numerical Index on pages 18–19 to cross-reference part numbers.

What if I need a part number that’s not listed?

Check the Notes page (20) for any updates. Some older superseded parts may not appear; contact GEHL with your serial number.
