Roadranger FS-4005C 2011 Parts Catalog

You’ve got a transmission on the bench and the wrong part number on the invoice. That’s hours wasted chasing a mismatched synchronizer or a bearing that doesn’t fit the countershaft. The Roadranger FS-4005C 2011 Parts Catalog stops that nonsense cold. This is the factory-issued parts list—not a reprint, not a third-party guess. 18 pages of OEM part numbers, kit breakdowns, and assembly groupings straight from Roadranger. Pull the correct input shaft, mainshaft, or shift bar housing part the first time. No cross-referencing from memory. No calling the parts house twice.

CASE and COUNTERSHAFT: What’s on Page 4

Page 4 of this Parts Catalog covers the CASE assembly. That’s the housing that holds everything together. If you’re rebuilding an FS-4005C, you need the exact casting number for the case, the magnet, and the bearing retainers. Page 6 follows with the COUNTERSHAFT ASSY—the gear cluster that rides on the countershaft. Each gear, spacer, and thrust washer has its own Roadranger part number. Using a generic bearing from the bin instead of the OEM spec? That’s how you get gear whine and early failure. This catalog gives you the numbers to order right.

Does This Parts Catalog Cover the Input Shaft?

Yes. Page 7 is dedicated to the INPUT SHAFT assembly. You get the main drive gear, pilot bearing, and any retained snap rings. If you’ve got an FS-4005C transmission that’s grinding in third, odds are the input shaft bearing is toast. The catalog lists the bearing part number, the shaft itself, and the seal kit. No guessing which aftermarket “equivalent” fits. Cemetery warranties don’t cover the tow bill when a wrong bearing seizes at 60 mph. Stick with the factory listing.

3 Reasons to Use OEM Parts Documentation

• Paint and fitment: Aftermarket parts often have subtle dimensional differences. OEM numbers guarantee the part was made to the exact print the transmission was built to.
• Kit accuracy: Roadranger groups related parts into Kits & Assemblies (page 8). A single K-number replaces a handful of individual pieces. Ordering a kit from the catalog instead of piecemealing saves time and cuts out mismatched batches.
• Update tracking: Roadranger updates part numbers when materials or suppliers change. The 2011 catalog reflects those revisions. An old catalog might list a superseded number—you order it, it’s discontinued. This edition catches you up.

For broader background on how these transmissions fit into vehicle drivelines, the Internal Combustion Engine overview helps, but your immediate need is getting the right gear. The catalog answers that directly.

Kits & Assemblies: Factory-Recommended Replacements

Page 8 dives into KITS & ASSEMBLIES. These aren’t generic overhaul sets. A kit with a K-prefix part number (e.g., K-12345) contains everything needed for a specific repair—seals, gaskets, bearings, maybe a synchronizer assembly. An A-prefix number (e.g., A-67890) is a pre-assembled Production Assembly, ready to bolt in. Page 3 explains how to read these designations. If you’re rebuilding the LEVER ASSY (page 9) or the MAINSHAFT ASSY (page 11), check the kit first. Often the kit costs less and includes parts you’d forget, like the shift fork retaining pins.

Verify Parts Before You Order

Page 12 (MISCELLANEOUS) lists seals, plugs, and fasteners that are easy to overlook. Page 13 covers REMOTE CONTROL components—for models with a remote shift option. Page 14 handles REVERSE IDLER GEAR ASSY, and page 15 wraps up with SHIFT BAR HOUSING. Every part number is linked to an illustration in the catalog’s parts breakdown. Lay the book open next to your workbench, match the numbers on the diagram to the part in your hand, then write the order. That workflow eliminates the “I think this is the right one” error.

If you maintain a fleet or work on multiple Roadranger models, pair this catalog with the Roadranger RTLO-14918B 2011 Parts Catalog – OEM Factory Document and the Roadranger RTLO-18918B-T2 2011 Parts Catalog – OEM Truck Parts Manual. For other variants, the Roadranger RTLO-14613B 2011 Parts Catalog – OEM Factory Document rounds out the lineup. Each document follows the same illustration-and-number system, so you don’t have to relearn the layout.

For industry context on how transmission parts catalogs support proper repair workflows, the Automotive Industry Overview discusses standardization trends. But right now, you need this book on the bench.

Can I use this catalog to cross-reference aftermarket parts?

No. This catalog lists Roadranger OEM part numbers only.

How do I identify a kit versus a production assembly?

Page 3 explains the difference. Part numbers starting with ‘A’ are pre-assembled Production Assemblies. Numbers starting with ‘K’ are kits. Kits contain groups of parts for specific repairs, like a synchronizer overhaul. Production assemblies are ready-to-install units. Using the correct type prevents ordering a subassembly when you need individual pieces. Always check the ‘Kits & Assemblies’ section starting on page 8 for the full list.
