GEHL RB1850 Parts Catalog

I have been turning wrenches for 28 years, and I have seen more parts catalogs than I care to count. The ones that get under my skin are the aftermarket reprints — diagrams so blurry you cannot read the reference numbers, part numbers that do not match what GEHL actually stamped on the bracket, and torque tables that list a range so wide it is useless. That is why when I need a part for a GEHL RB1850 baler, I go straight to the source: the GEHL RB1850 Parts Catalog. This is not a photocopy. This is the 48-page factory document that the dealer uses when you walk in and say ‘I need a new pickup tooth.’ It tells you exactly which part number to order, where it goes, and how it attaches.

Indexed Parts Breakdown: From Main Frame to Transmission

Each major assembly gets its own section with an exploded diagram and a numbered parts list. The Main Frame section covers pages 4-5. The Drawbar & Axle section is pages 6-7. Implement Drive Line, Shields & Covers on pages 8-9. Pickup on pages 10-11. Twinebox & Cutoff on pages 12-13. Pickup, Lift & Overfill Clutch on page 14. Bale Starter on page 15. Shuttle & Bale Size Indicator on page 16. There is even a Sprocket & Roller Part Number Guide on page 17 that cross-references common drive components — saves you from flipping back and forth when you are trying to match a sprocket. Roller Drive, Lower Rollers, Upper Rollers all get their own spreads. The Transmission is on page 29. That section alone is worth the price if you have ever tried to find a gear or bearing for that driveline.

Does This Parts Catalog Cover the GEHL RB1850 Transmission?

Yes. Page 29 is dedicated to the Transmission assembly. Every gear, shaft, bearing, seal, and snap ring is listed with its factory part number. You also get the hardware callouts — cap screws, lock washers, nuts — so you can order the correct fasteners. The standard hardware torque values are printed on the inside back cover. Do not trust generic torque charts; use the factory values for Grade 5 fasteners as specified in this manual.

3 Reasons to Trust GEHL’s OEM Documentation

First: the part numbers are verified against GEHL’s own inventory. Aftermarket catalogs may substitute superseded numbers or omit revisions. Second: the diagrams are scanned from the original printing — not a second-generation copy that lost resolution. Every reference line is readable. Third: the hardware table on the inside back cover gives you attaching hardware torque specs in imperial units, not some converted metric guess. If you have ever snapped a bolt because a generic chart said 75 ft-lbs when the factory spec is 58 ft-lbs, you understand why this matters.

Decal Locations: Critical First Step Before Ordering Parts

Pages 2-3 show all decal locations on the RB1850. Your serial number decal is under the top channel, near the center column of the left frame assembly. That serial number is required when ordering any part from GEHL. The manual tells you exactly where to look. If the decal is missing, you may need to determine the unit’s year of manufacture from other identifiers. The manual provides reference points.

Total Density Control (TDC) System Parts – What’s Listed

The Total Density Control system is covered on pages 24-25. This includes the springs, arms, sensors, and linkage that regulate bale density. If you are seeing uneven bales or the density control is not responding, you can trace each component from the diagram. The parts list includes the correct spring part numbers — aftermarket springs often have different rates. Do not substitute. This manual also covers the Rear Gate (pages 26-27) and Rear Gate Hydraulics (page 28), so you can diagnose hydraulic cylinder issues with the correct seal kit numbers.

48 pages. No filler.

Options & Accessories: Kits for Twine Wrapping, Crowder Wheels, and More

Options run from page 33 to 39. It includes Electric Twine Wrapping Kit 801143 with control box breakdown, Crowder Wheel Kit 802232, Light Crop Hold-down Kit 066779, 1000 RPM Conversion Kit 801552, 6″ Upper Belt Dutchman Kit 072042, Platform Belt Dutchman Kit 061253, Bale Counter Kit 801782, Hydraulic Twine Wrapping Kit 801088, Slow-down Sprocket Kit 066780, Dual Hydraulics Kit 801087, and several lacing and scraper kits. Each kit is illustrated with its own parts list. If you are retrofitting an accessory to an older RB1850, these pages are essential.

If your shop works on multiple GEHL models, consider the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog for skid loaders, the GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs for larger loaders, and the GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual for compact excavators. For general engine principles, this Wikipedia article on diesel engines provides background, but always use the factory manual for part numbers.
