GEHL 280 2008 Parts Catalog – Factory OEM Specs for All-Wheel-Steer Loader

You’ve got a 280 All-Wheel-Steer Loader in the bay with the serial number tag reading 341020017 or later. The aftermarket parts book you pulled off the shelf lists a bolt that doesn’t match the thread pitch you just stripped out. That waste of time ends right here. This is the factory GEHL 280 2008 Parts Catalog – the same binder GEHL shipped to dealers. It covers every nut, seal, bearing, and hydraulic line by the original part number. You order one time and the part fits. No guessing if the aftermarket supplier swapped a metric cap screw for a Grade 8.8.

Torque Specifications – Where the Factory Data Lives

Every mechanic knows that a loose bolt on a loader arm turns into a liability. Page 1 of this catalog gives you the serial number range – 341020017 and up – so you know this manual matches your machine. The introduction page includes the conversion: Newton-meters times 0.738 equals foot-pounds. Standard attaching hardware torque values are listed near the back. You get the number, you torque it to factory spec, you move on to the next job. No chasing down a third-party chart that may or may not be for your year model. This is the same torque data GEHL used on the assembly line.

Need the specific torque for a cap screw on the hydraulic cylinder mount? Flip to the Torque Specifications section. The catalog lists standard hardware torque separately from the illustration-specific callouts. Metric torque values in the drawing callouts are in N-m; the conversion table is right there. You do the math once, you torque it right, you sleep better.

Alphabetical Index: Finding Parts Without the Guesswork

The parts catalog uses a two-part index. First an alphabetical index from Numerics through O, then P through W. You need a “Hydraulic Cylinder” – look under “H” or check the Numerical Index if you already have a reference number. GEHL organized this so a tech can find a part in under a minute. Each listing points you to the illustration page where the exploded view shows the part in position. The reference numbers are circled if the item is a complete assembly. That means you know whether you need the whole valve block or just a seal kit. A small bag icon next to a reference number indicates a seal kit – o-rings, backup rings, the works. That detail alone has saved me hours of cross-referencing.

Does This Catalog Cover Your Serial Number?

Serial number breaks are printed clearly. You’ll see notations like (SN 999 and before) or (SN 1000 – 2000). The manual also marks exceptions: (SN 999 and before except 997). If your 280 has a serial number between the printed range, the catalog includes it. If your machine is older than 341020017, you need the earlier edition. Check the serial plate on the front cab panel. Right and left are from the operator’s seat facing forward – that matters when you order a left-hand cylinder and get the wrong one. The catalog calls it out exactly.

3 Reasons to Use OE Parts Instead of Aftermarket Copies

First, the part numbers in this catalog are genuine GEHL service parts. The introduction states: use only genuine GEHL service parts for continued proper operation. Second, the catalog includes revision D dated June 2008 – any engineering changes after that date are not covered, but GEHL reserves the right to make improvements without retrofitting older units. Third, the hardware spec is Grade 8.8 cap screws, cadmium or zinc plated. Aftermarket suppliers often substitute lower grades. You put a Grade 5 bolt in a loader pivot and you’re going to be replacing it again next season. This catalog gives you the correct specification so you order the right grade every time.

How to Read the Exploded Views and Part Lists

Each illustration has reference numbers connected to a parts list. Additional information may follow the reference number – things like “includes bearing” or “order as a kit”. If the reference number is circled, you’re looking at a complete assembly. That means you can order the entire hydraulic valve block as one line item instead of piecing together a dozen individual parts. The “AR” abbreviation means “As Required” – used for bulk items like O-ring cord or hose by the foot. Every abbreviation is defined in the table on page 2. Keep that page bookmarked.
