GEHL 1870 Parts Catalog – Factory Part Numbers & Exploded Views

Description

If you’ve ever tried to track down a replacement roller or belt for your GEHL 1870 round baler using a generic parts list, you know the headache. Wrong part numbers, missing hardware, no torque values. This factory GEHL 1870 Parts Catalog puts 62 pages of OEM data on your bench. The exploded views show every nut, bolt, and seal with the exact part number. The hexagon symbols tell you the torque in foot-pounds. The teardrop symbols mark where oil or grease goes. None of that guesswork.

You’re looking at a Parts Catalog, not an operator manual. That means it focuses on part numbers, assemblies, and hardware. But the torque and fluid callouts are baked into the diagrams. Page after page of detailed drawings with reference numbers that match the parts list. If you’re rebuilding a transmission or replacing a gate hydraulic cylinder, this is your cheat sheet. The manual covers everything from the drawbar and axles (pages 10-11) to the gate hydraulics (pages 24-25) and the total density control system (pages 28-31). Each section has its own exploded view with hardware callouts. Even the options and accessories section (pages 41-50) includes kits like the crowder wheel, stripper assembly, and automatic chain oiler. That’s 62 pages of factory-sourced data that no aftermarket publisher can duplicate.

Transmissions Section – Pages 34-35

Transmission is a make-or-break system on a round baler. The manual breaks down the shuttle and drive components. You get a clean exploded view of every shaft, bearing, and snap ring. Part numbers are right there. Need the shift fork? Page 35. The spline coupling? Page 34. No guessing. If you’re ordering transmission parts, bring this page to your dealer. They’ll respect a customer who has factory part numbers.

Decal Locations and Frame Assembly – Pages 2-7

Starts with decal placement – important for safety compliance and resale value. Then the frame and fenders with all bolt callouts. Note the torque hex symbols on the diagrams. The frame bolts on page 6 show a hex with “180” – that’s 180 ft-lb. Don’t guess. Use the torque values on the inside back cover for standard hardware, but pay attention when the diagram has its own hex.

Bale Starter and Scraper – Pages 13-16

These pages cover the pickup, starter roll, and scraper assemblies. Common wear points that eat into your season. The exploded view shows the overfill clutch, shear bolt, and scraper blades. If you keep snapping shear bolts, check the torque spec in the hex symbol on page 13 – might be over-torqued or the wrong grade. The parts list also tells you whether the bolt is Grade 5 or Grade 8.

Torque Specs Inside Back Cover – Do Not Overlook

Torque matters. Use the factory numbers.

The inside back cover lists standard attaching hardware torque values in foot-pounds for Grade 5 and Grade B nuts. But the manual also has specific torque values in hex symbols throughout the diagrams – always follow those when present. I’ve seen guys strip threads because they used a generic chart. Don’t be that guy.

Cross Frame & Twine Tie Mechanism – Pages 32-33

The twine tie system is finicky. This factory section shows the cross frame assembly and the twine tie mechanism in detail. You’ll see the tie arms, knife, and belt – all with part numbers. If your baler is leaving loose bales, check these pages for the correct spring or linkage part.

Hitchjacks – Pages 38-39

If you need to replace the hitch jack or its mounting bracket, this section shows the assembly with all hardware. The drawbar and axle section (pages 10-11) also tie into this. Having the correct part numbers for the jack and cotter pins saves a trip to the dealer.

Options & Accessories – Pages 41-50

This section covers add-on kits you might need: the actuator, 1000 rpm conversion kit, manual-electric twine tie control, auto-electric twine tie, crowder wheel kit, stripper assembly kit, audible bale size indicator, transport lights, packing roller lagging kit, scraper kit, and automatic chain oiler. Each kit has its own exploded view with part numbers. If you’re retrofitting a twine tie system, the parts are all here.

Why the GEHL 1870 Parts Catalog Beats Aftermarket Diagrams

Aftermarket parts catalogs often renumber parts or skip hardware. This manual uses the original GEHL part numbers and includes reference numbers with torque and fluid callouts. The teardrop symbol indicates a wet product (oil or grease). The hexagon symbol tells you the torque in ft-lb. You don’t get that from a third-party scan. And the page count? 62 pages of pure parts data, plus alphabetical and numerical indexes on pages 52-57 to find any part fast. No generic cross-references.

If you also work on other models, check the GEHL 1400 1800 1870 Parts Catalog for additional coverage. For operating procedures and larger torque tables, pair this with the GEHL 1870, 1470 Operators Manual – Factory Baler Specs & Torque.

Does this manual include transmission part numbers?

Yes, pages 34-35 show the full transmission assembly with part numbers.

How are torque values indicated in the diagrams?

In the exploded view, a number inside a hexagon next to a reference number indicates the required torque in foot-pounds. For example, on page 16 you’ll see a hex with ‘150’ – that means 150 ft-lb on that bolt. The inside back cover also has standard torque specs for Grade 5 hardware. Always check the hex symbol before torquing, because some fasteners have specific values different from the standard chart. The manual also uses a teardrop symbol for fluid applications, like oil or grease, with a number corresponding to the description in the parts list.

Stop guessing and order the right parts. Access the Factory Manual and keep your GEHL 1870 running tight.
