GEHL 165 Parts Catalog

You’re holding 24 pages of factory part numbers, exploded views, and torque specs that came straight from GEHL. Aftermarket catalogs? They guess. This one tells you exactly which bolt, which shim, which cutterbar disc goes on your 165 Disc Mower. I’ve seen too many jobs go sideways because someone used a cross-reference chart from a third-party site. Don’t be that guy. This GEHL 165 Parts Catalog is the only source you should trust for part numbers. When you call the dealership to order a gear or a seal, you need the exact part number. One digit off and you get the wrong part, then you’re waiting another week. That’s time you don’t have. The catalog also tells you which assemblies are superseded. For example, the early cutterbar gearcase used a different input shaft. You won’t know unless you have the factory documentation. That’s why I keep this catalog in the shop – not a generic PDF from a forum.

Decal Locations and Safety Markings

Pages 2-3 show every decal that belongs on the frame and cutterbar. Safety decals, SMV emblem, torque warnings. If you’re replacing a mower that got repainted, you need this to put the stickers back where they belong. GEHL didn’t put them there for decoration. Don’t skip the decal check.

What Torque Values Does This Catalog Include?

Inside back cover has the standard hardware torque specifications. Grade 5 cap screws, hex nuts, flanged lock nuts – all listed in foot-pounds. No metric conversion guesswork. If you’re tightening a bolt that holds the cutterbar disc, you need the hexagon symbol in the exploded view – the number inside is the torque value. That’s factory data, not a Youtuber’s opinion. Follow these specs and your hardware stays tight season after season.

Cutterbar Gearcase: Exploded View Breakdown

Page 6 covers the cutterbar gearcase assembly. Each gear, shim, and bearing has a reference number. The parts list tells you the GEHL part number and quantity. If you need to rebuild the gearcase, you order from this page. Don’t try to match by dimension – GEHL changed the shaft diameter in later production runs. Use the serial number to confirm which version you have.

Use the Numerical Index for Fast Part Lookup

Those two pages are a numerical index of every part number in the catalog. Need to find a part number you saw on an old invoice? Look it up here. It tells you which assembly page it appears on. This saves digging through 22 pages of exploded views. I keep a printout of these two pages in my toolbox.

GEHL 165 Parts Catalog: 24 Pages of OEM Data

Every part that can be ordered for the 165 Disc Mower is here – from the frame assembly on page 4 to the options and accessories on pages 17-18. The belt drive, PTO, swath board, inner swath board, safety shield, tool box – all covered. If a part isn’t in this catalog, it doesn’t exist from the factory. The PTO assembly on page 12 connects to a tractor’s diesel engine. For background on how those engines deliver power, see this Wikipedia article on diesel engines.

FAQ

Does this catalog include torque specifications?

Yes, on the inside back cover.

How do I identify the correct part number for my mower?

Each exploded view has reference numbers. The parts list gives the part number, description, and quantity. Match your serial number to the model plate located on the gusset of the main frame. Right and left are determined from behind the mower. Use the Numerical Index on pages 19-20 to cross-reference part numbers. If a reference number has a hexagon symbol, the number inside is the torque value in foot-pounds. For bolts, grade 5 unless specified. This level of detail is what you get from an OEM catalog, not aftermarket copies.
