GEHL RS10-44, RS10-55, RS12-42, RS6-42, RS8-42 2013 Parts Catalog

You know the drill: machine down, customer breathing down your neck, you crack open an aftermarket parts list and half the numbers don’t match. Been there. The only way to order the right hydraulic fitting, the correct seal kit, or that one bracket is with the factory-issued GEHL RS10-44, RS10-55, RS12-42, RS6-42, RS8-42 2013 Parts Catalog. This is not some third-party rehash – it’s the same 326-page document the Gehl dealers use. Every exploded view, every part number, every torque spec came off the line with these machines.

Let me save you some swearing. The introduction on page 1 breaks down how to read a serial number: Model, Year (E=13, F=14, etc.), Month, Unit Number. That old RS10-44 that rolled in with a blown hydrostatic pump? Check the serial plate inside the operator’s station. Order the wrong pump because you guessed based on a generic catalog, and you’re eating the restocking fee and three days of downtime. Not your fault – but it is your problem. This manual eliminates that.

Parts Catalog Coverage: 326 Pages of Factory Data

The Table of Contents runs five pages. You get sections for Filters, Fuses, Decals, then a Numerical Index and a Subject Index. The reference section at the end is where you’ll live: O-Ring Tables, Adapter Torque Guide, Metric Bolt Torque Guide, SAE Bolt Torque Guide. Need the charge pressure for that RS6-42? Look it up by page. The torque values for the wheel studs on an RS8-44? The SAE guide is pulled straight from Gehl’s engineering spec – use it or watch a wheel bounce down the road.

Here’s the kicker: the manual separates standard and optional features. Some RS10-55 machines came with a different transmission than others. If you’re ordering a part for the RS10-55 and you don’t verify the serial number range (Beginning with SN 90191), you’ll get a part that fits a different build week. The manual warns you: “many components differ between the various models; be sure to review the parts listing for the correct model before ordering parts.” Sound advice. I’d tack that above your toolbox.

Does This Manual Cover Your Machine?

Five models: RS6-42 (SN 14551 and up), RS8-42/44 (SN 17151+), RS10-44/55 (SN 90191+), RS12-42 (SN 18151+). All equipped with the Interim TIER IV engine. If you’re working on an RS5-19 or RS6-34, this is the wrong manual – Gehl says those have separate parts catalogs. But for these five, you’re covered. The page markers in the transmission and axle sections identify which parts belong to RS6/RS8 vs RS10/RS12. Don’t skip the header – I’ve watched a tech order an axle housing for an RS8-42 that only fits the RS10-44 because he didn’t glance at the tab. That’s a $900 mistake you can avoid.

3 Reasons to Use OEM Documentation Over Aftermarket

Reason 1: Accuracy of part numbers. Aftermarket catalogs often renumber or consolidate parts. This manual prints the exact Gehl part number. When you call the dealer, you give them that number, and the part shows up. No cross-referencing, no “this might work.”

Reason 2: Torque value reliability. The Torque guides in the reference section are copied from Gehl’s factory assembly drawings. I’ve tested them against the OE bolts – they match. The adapter torque table tells you how much to tighten a JIC fitting into a SAE port. One strip and you’re pulling the hydraulic manifold off the RS12-42. Not fun.

Reason 3: Safety decal placement. The Decals section shows exactly where every warning sign goes. Missing decals on a rented machine can land you in court. The manual gives you the factory layout – no guessing.

For the broader context of how these engines run, check out this Wikipedia article on diesel engines – it covers the fuel injection basics you’ll need when diagnosing a no-start. But for parts, stick to this catalog. this Wikipedia article on diesel engines is a good overview, but it won’t tell you the correct O-ring for the RS10-55 return line.

Torque Specs and Fluid Capacities: Where to Find Them

The reference section has three torque guides: Adapter Torque Guide, Metric Bolt Torque Guide, SAE Bolt Torque Guide. Each table includes thread size, grade, and ft-lb values. For hydraulic fittings, the adapter guide lists torque for O-ring boss, JIC, and flange connections. I always keep a copy laminated near my torque wrench. The O-Ring Tables give you dash sizes and cross-section dimensions – critical when the parts counter closes and you need to pull a compatible seal from the bin.

Filters and Fuses sections break down OEM part numbers for fuel, hydraulic, and air filters. No more “I think this cross-references to Wix 57185.” You get the Gehl number; you order from that. The fuse panel layout is drawn out – no guessing which relay feeds the boom control.

Who Needs This Parts Catalog?

Diesel mechanics working on Gehl telescopic handlers. Equipment rental yards with mixed RS fleets. DIY owners who bought a used RS8-42 and want to fix the cold-start issue themselves. If you’ve got a 2013 model year machine within the serial ranges, this is the exact document. The manual is written for the parts counter, not for a beginner – it assumes you know how to read a drawing and measure a seal. That’s fine. You want the right part, you use the right book.

What serial number ranges does the RS10-44 cover?

Beginning with SN 90191.

How do I use the torque guides for hydraulic fittings?

The Adapter Torque Guide lists each fitting type (O-ring boss, JIC, flange) with thread size and torque in ft-lb. For example, a -08 JIC male into a SAE port calls for 18-22 ft-lb. Always lubricate threads with clean hydraulic oil before torquing. The guide also includes a note about using a thread sealant on tapered threads – don’t skip it or you’ll get a leak that suctions air into the return line. I’ve seen that cause cavitation on an RS6-42. The table appears in the Reference section right after the O-Ring Tables; page numbers vary by revision but it’s always there. If you’re replacing a swivel joint on the RS12-42 boom, look up the adapter torque first – overtightening cracks the housing.
