GEHL 1070, 1090 Parts Catalog – Factory OEM Specs for Mower Conditioner

Spent an afternoon trying to figure out which reel bearing fits your MC1090? I’ve been there. Aftermarket catalogs often skip the serial number splits or use generic hardware callouts that don’t match. That’s why you need the actual GEHL 1070, 1090 Parts Catalog – a 40-page OEM document that gives you factory part numbers, exploded diagrams, and the torque chart you can trust. No reprints, no aftermarket guesswork – just the same book the dealer uses.

Main Frame Breakdown for MC1070 and MC1090

Two different frames, two separate sections. Pages 4-6 cover the MC1070 main frame, pages 7-9 cover the MC1090. Each page shows the assembly with callouts for every weldment, bracket, and fastener. The orientation note on page 2 tells you right and left are determined from behind the unit facing forward – the transmission and driveline sit on the left side. If you’re swapping a cracked frame member, you need these exploded views to order the correct part.

Sickle & Cutting Mechanism – Where Blades and Guards Meet

Pages 14-16 break down the sickle bar, guards, hold-downs, and wear plates. The parts list uses abbreviations like HHCS (Hexagon Head Cap Screw) and LW (Lock Washer) – all defined in the introduction. Common hardware like nuts and cap screws are listed but not illustrated; you match them to the attaching hardware table inside the back cover. That table also includes standard torque specs for Grade 5 bolts.

Transmission & Drives – Two Input Speeds Covered

Page 25 shows the complete Transmission and drives section. Then pages 28 and 29 separate the input transmissions: one for 540 RPM PTO, one for 1000 RPM. If your machine came with a different PTO option, make sure you order the right input shaft assembly. The telescoping drives on page 27 and tubular drives on page 26 cover the driveline components between the gearbox and rollers. Need a replacement U-joint yoke? The part number is right there in the diagram.

Torque Chart on the Inside Back Cover – Don’t Skip It

Standard hardware torques for Grade 5 cap screws and Grade B nuts are printed inside the back cover. That’s where you also find the attaching hardware table with part numbers for common fasteners. I’ve seen too many guys torque a sickle-bar hold-down to 50 ft-lb because they assumed – then wonder why the guards crack. Use the factory chart. For general bolt torque theory, check this Wikipedia article on diesel engines; the same principles apply to any bolted joint.

Does This Manual Cover the Reel?

Yes, but watch the serial number break. Pages 18-19 cover reel parts for MC1070 before serial #4101 and MC1090 before serial #8702. Pages 20-21 cover units after those serial numbers – the reel frame and bat assemblies changed. If you order a reel arm from the wrong section, it won’t fit. The manual also includes decal location (pages 2-3) and a numerical index (pages 33-35) so you can look up a part number quickly.

Frequently Asked Questions

What models are covered in this parts catalog?

GEHL 1070 and 1090 mower conditioners.

How do I determine the correct part number for my machine?

Locate the serial number plate on the front left side of the main frame. Then note the model (1070 or 1090) and serial number. The manual splits sections by serial number ranges – for example, the reel sections use before/after #4101 for the MC1070 and #8702 for the MC1090. Use the numerical index (pages 33-35) to cross-reference part numbers. If the part is common hardware like a bolt, refer to the attaching hardware table inside the back cover. Common hardware is listed in the parts list but not illustrated – you use the table to get the correct Grade 5 cap screw or Grade B nut part number.
