Matching a sheared chaincase sprocket to a part number is the job this 66-page Gehl parts catalog (publication 909748) handles, covering four mixer feeder models. Exploded views fill most of the Gehl 8280, 8285, 8330, 8335 parts catalog PDF, breaking the hitch, axles and weighbars, main drive, augers, chaincase and both discharge conveyor styles down to callouts and part numbers. When a part comes off worn smooth, alphabetical and numerical indexes let you trace it back to its assembly, and the accessory pages list knife, paddle, ladder and tank liner kits. Confirm your driveline before ordering: the 540 RPM PTO is standard, 1000 RPM is optional, and the gearbox splits into separate Model 8 and Model 9 breakdowns. One wrong gearbox part means paying freight twice. Bookmarked and text-searchable, the PDF rides on your phone or shop laptop, so it's in the feed alley wherever the mixer sits.

Gehl 8280, 8285, 8330, 8335 Common Problems This Manual Covers
Gehl 8280, 8285, 8330, 8335 mixer feeder chaincase shear sprocket and roller chain part numbers hard to identify
Check the Chaincase exploded view starting on page 20 and find the shear sprocket on the gearbox input shaft. Match its callout to the parts list, then confirm the roller chain, seal plate, and bushing on the same pages. Order them together. Verify your model and serial number against the Introduction on page 2 first.
Manual Section: Chaincase p. 20Replacing auger drive roller chain, but idler arm assembly, extension spring, and offset link part numbers unclear
Check the Auger Drives exploded view on page 18. Trace the drive hub, idler sprocket, and idler arm assembly in order. Match each callout to the parts list, including the extension spring and offset link, so the new roller chain goes on with the right tensioning hardware. Verify your model number before ordering.
Manual Section: Auger Drives p. 18Top and bottom auger flange bearing assembly, backing plate, and adjustment bracket part numbers hard to match
Check the Augers & Auger Bearings exploded view on page 16 and confirm whether you are working on the top auger or the bottom auger. Match the flange bearing assembly, backing plate, adjustment bracket, and torsion spring callouts to the parts list. For individual auger parts, use the auger breakdown in Component Breakdowns on page 38.
Manual Section: Augers & Auger Bearings p. 16Discharge door hydraulic cylinder, relief valve, hose, and quick-disconnect part numbers difficult to identify
Check the Discharge Door & Hydraulics exploded view on page 26. Follow the circuit from the quick-disconnect through the hydraulic fittings, relief valve, and hoses to the hydraulic cylinder, and match each callout to the parts list. To identify the cylinder seal kit, use the hydraulic cylinder breakdown in Component Breakdowns starting on page 38.
Manual Section: Discharge Door & Hydraulics p. 26PTO shaft shield, flange bearing assembly, and lock collar part numbers on main drive hard to find
Check the Main Drive exploded view on page 14, then match the callouts to the parts number list on page 15. Confirm the flange bearing assembly, ball bearing, lock collar, PTO shaft shield, and grease fitting together. For PTO repair kits, check the RPM PTO breakdown in Component Breakdowns starting on page 38.
Manual Section: Main Drive p. 14Discharge conveyor sprocket, bearing, and shaft parts list unclear between one-piece and two-piece conveyor versions
Verify which discharge conveyor is on the machine before you order anything. Check the One-Piece Discharge Conveyor exploded view on page 28 or the Two-Piece Discharge Conveyor on page 32. Then match the sprocket, bearing, collar, and shaft callouts to that section's parts list. Parts from the other section may not fit.
