GEHL 1400, 1800, 1870 Parts Catalog – Factory OEM Parts Breakdown

I’ve seen more than one guy order the wrong actuator because he guessed from a faded sticker. Then he sat waiting a week while the machine sat dead. That’s why you need the actual GEHL 1400, 1800, 1870 Parts Catalog – not a photocopy from someone’s uncle. This is the original 24-page factory document that tells you exactly which bolt goes where and how tight it needs to be.

What’s Inside the 24-Page Parts Catalog?

Starts with an introduction explaining how to read the part numbers and serial number locations. Then goes straight into decal locations on pages 2-3 – if you’re rebuilding a baler that’s missing warning labels, that section alone is worth the price. Pages 4-5 cover rollers and brackets. Right side assembly on pages 6-7, left side assembly on pages 8-9. Shields, control box, and harnesses fill pages 10-13. Bale ramp shields on page 14. Components pages 15-16 show the two actuator versions – 126236 and 126215 – with torque callouts right next to the part numbers.

Torque Specifications: Inside Back Cover

Standard attaching hardware torque values live on the inside back cover. That’s where you’ll find the numbers for Grade 5 bolts and Grade B nuts. The manual uses a hexagon symbol next to fastener callouts to indicate foot-pounds torque. If you skip that step, you’ll either strip threads or leave something loose. Neither is acceptable on a baler spinning at PTO speed. The torque data is OEM – not some aftermarket approximation.

Decal Locations and Rollers & Brackets

Pages 2-3 map every warning and instruction decal. If your machine is missing a decal, you can order the exact one from the part number in this catalog. Pages 4-5 detail the roller and bracket assemblies – these are the parts that take the biggest beating on a round baler. The exploded views show every washer and fastener.

Actuator Assembly: Two Versions

Two different actuators are used depending on the machine: part number 126236 on page 15 and 126215 on page 16. They look similar but the internal porting differs. This catalog gives you the exploded view so you can identify which you have before you call your dealer. Saves you a return trip. The hexagon torque symbols are printed next to each fitting – I’ve seen guys guess at those and end up with hydraulic leaks.

Numerical Index: Quick Part Number Lookup

Pages 17-18 contain the numerical index. If you already have a part number but don’t know where it goes in the machine, you look it up here. It cross-references to the illustration page and reference number. No flipping through the whole book like a scavenger hunt.

Audience Fit: Who Should Use This Parts Catalog?

If you own a GEHL 1400, 1800, or 1870 round baler and you ever plan to order replacement parts, this manual belongs in your toolbox. The farmer doing his own maintenance, the small shop that works on balers, and the dealer parts counter all need this. Beginners should start by reading the introduction on how to read the exploded views – it’s not complicated but it’s specific. The abbreviation table on page 2 decodes things like HHC (Hex Head Cap) and HWHTC (Hex Washer Head Thread Cutting). Without that, you might order the wrong fastener type.

Source Validity: OEM vs Aftermarket Documentation

Aftermarket parts catalogs often redraw exploded views and leave out torque callouts. This is the opposite – it’s the original GEHL publication, Form No. 907082. It replaces document 906134. The part numbers are the same ones stamped on the castings. When you order a part using this catalog, you get what the factory intended.

Frequently Asked Questions

Does this catalog cover the GEHL 1470 baler?

No. This parts catalog specifically covers the 1400, 1800, and 1870 models only. The 1470 is a different chassis.

Where do I find the serial number on my 1870 baler?

Left panel assembly below the drive assembly. This is noted on page 1 of the manual.

Are the torque specs given in foot-pounds or inch-pounds?

All torque values in this manual are in foot-pounds. The hexagon symbol indicates the number. Standard hardware torque specs are also on the inside back cover for common Grade 5 bolts and Grade B nuts. Some hydraulic fitting torque callouts appear in the actuator sections on pages 15-16. Always use the value printed next to the part – don’t assume standard hardware torque applies to a hydraulic fitting because it doesn’t. Over-torque a JIC fitting and you’ll crack the flare. Under-torque and you get a weep. The factory values are tested for that specific assembly.

Can I use this catalog to order replacement tires for my GEHL baler?

Policy prohibits selling replacement tires directly. Wheel sets are available with tire size info to help you buy locally. See the introduction notes.

Stop wasting time with mismatched parts and missing torque specs. Access the Factory Manual and keep your baler running with the right parts the first time.
