GEHL 1287 Parts Catalog – What You Actually Get on the Bench

If you have ever ordered a seal kit or a hydraulic cylinder for an older 1287 spreader and ended up with the wrong size because some aftermarket catalog guessed at the part number, you know the frustration. That waste of time costs you money—and in a shop, billable hours lost. This is the GEHL 1287 Parts Catalog, printed by GEHL Agriculture, not a recompiled PDF from a third party. 72 pages, OEM original, Form 907543 Revision B. You get the same exploded views and part numbers the dealer uses.

Let me walk through what matters when you have this manual open on the toolbox.

Decal Locations and Frame Assembly

Pages 2-3 show exactly where the model and serial number decal lives—left side of the main frame, front left corner of the box. If you are replacing a cracked frame or axle hub, the Main Frame, Floor, Axle & Hub Assembly on pages 8-9 call out every bolt and bushing. No cross-referencing to aftermarket tables. The manual tells you the reference number, the description, and the quantity. For a part like the Valve block on the flow control, page 30-31 lists it with the correct part number.

72 Pages of Factory Specs

Seventy-two pages may sound thin compared to a full service manual, but this is a parts catalog—not a repair manual. Every page is packed with exploded diagrams and numbered callouts. Need to know which Cylinder goes on the Apron Control Hydraulic Cylinder assembly? Pages 14-15. The beater drive gearbox? Page 28-29. You get the Part Number, description, and quantity. No fluff, no reprints. The index runs from page 59 to 67, alphabetical and numerical, so you can find any part in seconds. Compare that to digging through a generic website that lists parts by vague categories.

Hydraulic Cylinder: Exploded Views and Seal Numbers

If you are tearing down an Endgate Hydraulic Cylinder, the manual includes it on pages 50-51 (though the tag says NO TAG). The Hydraulic Apron Drive Motor on pages 26-27 shows the motor assembly with every internal seal. Pay attention to the tear-drop symbol in the parts list—that means a wet product like oil is applied at assembly, and the number inside the tear drop corresponds to a note in the description. Torque values appear inside a hexagon symbol next to the reference number in foot-pounds. That is factory data, not a guess from an online forum.

Need a Part Number for the Beater Drive Gearbox?

Pages 28-29 cover the Beater Drive Gearbox. The exploded view shows the housing, gears, bearings, and seals. If you have ever ordered a “beater gearbox rebuild kit” from an aftermarket supplier and got the wrong gasket, you understand the value of having the OEM part number in hand. This manual gives you the exact GEHL reference. You can also verify the Flow Control Valve on page 30-31 and the Standard Apron Drive Front Drive on page 16-17. For the PTO assembly, pages 4-5 list the driveline components.

Get the Right Torque Data

Page 68 provides Hydraulic Fitting Torque Data. Standard Hardware Torque Specifications are on the Inside Back Cover. No more wondering if a 5/8 Grade 5 bolt gets 200 or 250 ft-lbs. The manual tells you. And if you are replacing cap screws, note that unless otherwise specified, all cap screws or bolts are Grade 5, zinc plated; hexagon nuts for Grade 5 are Grade B. Those are the factory build specifications. Use them.

Who Should Buy This Manual

Home garage mechanics and small farm operators who own a GEHL 1287 Manure Spreader. If you do your own repairs and want to order the correct parts the first time, this manual eliminates the guesswork. Also useful for shops that service these units—having the OEM parts catalog on hand saves the “can you cross-reference this number” phone calls. Pair it with the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog if you work on multiple GEHL models. The GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs and GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual cover other common machines in the lineup.

Source Authenticity: OEM vs Aftermarket

This is a direct scan of the original GEHL Agriculture document (Form 907543 Revision B). The introduction on page 2 states: “For your safety and continued proper operation, use only genuine GEHL service parts.” The abbreviations table lists every fastener code (CS, FCS, HN, etc.). Aftermarket catalogs often omit torque data or abbreviate incorrectly. Here you get the real thing. The manual also includes a note about tire replacement—Company policy prohibits selling replacement tires, but wheel sets are available. That is detail you will not find in a third-party compilation.

FAQ

Does this manual include part numbers for the hydraulic cylinders?

Yes. Apron Control Hydraulic Cylinder (pages 14-15), Endgate Hydraulic Cylinder (pages 50-51), and Hydraulic Drive Motor (pages 26-27) all have exploded views with reference numbers and part descriptions.

How do I find a specific part number quickly?

The Numerical Index on pages 60-67 lists every reference number in ascending order with the corresponding page and description. If you have the old part number, look it up there. The Alphabetical Index on page 59 covers assemblies like “Beater” or “Apron”. Cross-referencing is instantaneous. No need to flip through all 72 pages.
