Roadranger RT-7608LL 2011 Parts Catalog – Factory Specs for Your Workbench

You ever order a part for a Roadranger RT-7608LL and get the wrong seal, wrong bearing, or a shaft that doesn’t fit? That’s what happens when you rely on aftermarket catalogs or a parts guy reading a blurry screen. This 34-page OEM factory Parts Catalog from 2011 is the only document that lists every single factory part number for the RT-7608LL transmission. I’ve been turning wrenches since before digital parts lookups existed, and I can tell you: if the number isn’t in this book, it didn’t come from the factory. Save yourself the return trip and the lost labor.

34 Pages of Factory Part Listings – No Guesswork

Thirty-four pages doesn’t sound like a lot until you crack it open. Each page is a dense, U.S.-sourced OEM layout with exploded-view illustrations and callouts that match the actual transmission on your lift. The table of contents runs from AUXILIARY DRIVE GEAR (page 4) all the way down to REVERSE IDLER (page 26). Every bearing, synchro, shift lever, housing, and gasket is listed with the exact Roadranger part number. No cross-references to aftermarket boxes. No “use this if you can’t find that.” This is the factory list.

Inside the Manual: AUXILIARY DRIVE GEAR to RANGE CYLINDER

Need the input shaft assembly? Turn to page 13. The mainshaft and auxiliary synchro assembly lives on page 18. Want to find the right range cylinder? Page 24. The catalog breaks down every subassembly: CASE (AUX) on page 5, CASE (FRONT) on page 7, COUNTERSHAFT & BRGS(AUX) on page 8, FILTER REGULATOR on page 10, and H & C valves (both the 19470 and A-5000 variants) on pages 11–12. It even covers isolators (page 14), kits and assemblies (page 15), and levers/housings (page 16). Every section heading matches the original factory print, so you can hand this to any tech and they’ll find the part in under two minutes.

Why OEM Documentation Beats Aftermarket Catalogs

Aftermarket manuals have their place – in the trash when you’re trying to order a $200 synchronizer and the picture looks close but the splines are wrong. This is a Roadranger factory document, printed in 2011, scanned from the actual OEM publication. It doesn’t have third-party errors, it doesn’t consolidate multiple models into one messy chart, and it doesn’t tell you to “consult dealer for superseded parts.” Every part number is a direct-from-Roadranger reference. If you need to verify a part against the actual transmission, you can. No phone tag, no cross-ship returns. For related transmissions, check the Roadranger RTLO-14918B 2011 Parts Catalog – OEM Factory Document or the Roadranger RTLO-18918B-T2 2011 Parts Catalog – OEM Truck Parts Manual for similar drivetrain components. The Roadranger RTLO-14613B 2011 Parts Catalog – OEM Factory Document also follows the same factory layout.

Who Should Use This Catalog?

If you own, maintain, or rebuild a heavy-duty truck with an RT-7608LL, this catalog is your parts bible. DIY mechanics working on a fleet truck will use it to order the correct bearings and seals. Home-garage guys who pull a transmission out of a salvage yard will rely on it to cross-check before buying new parts. Professional shops that bill by the hour cannot afford the time wasted with wrong parts. This catalog puts the correct number in your hand. You don’t need to be a master tech – you need to be able to match an illustration to your transmission. That’s it. For broader context on heavy-duty vehicle systems, the Automotive Industry Overview covers drivetrain design, and you can read about Internal Combustion Engine fundamentals if you want the theory behind the torque. But for part numbers, stick to this book.

How to Use the Illustrated Parts List (Page 3 Explained)

Page 3 of this catalog is the instruction page for reading the illustrated parts list. It’s one page, but it’s the key to using the whole document. It explains the column layout: item number, part number, description, quantity per assembly. The exploded-view drawings reference each item with a leader line. You identify the part on the drawing, note the item number, then read across to get the factory part number. No interpretation required. This is the same system Roadranger has used for decades. Learn it once, and you can use any Roadranger factory catalog.

FAQ

Does this catalog include torque specs or repair procedures?

No. This is a Parts Catalog, not a service manual. It lists part numbers and quantities only. For torque values, you need the separate factory service manual for the RT-7608LL.

Will this catalog help me identify a part if my transmission has been modified?

If the transmission was modified using non-OEM parts, this catalog won’t list them. It covers only factory-stock components. For modified units, you’ll need to cross-reference aftermarket part numbers against the OEM numbers listed here.

How are the part numbers organized?

Every section groups parts by subassembly – for example, all mainshaft components are on pages 18–20, all shift components under LEVERS/HOUSINGS on page 16. The index on page 2 lists each section and its starting page. You can find any part by locating the correct subassembly in the TOC.

Is this a reprint of an aftermarket guide?

No. This is a direct scan of the 2011 factory-issued Roadranger Parts Catalog. It is the same document that dealerships used. No changes, no edits, no third-party additions.

Thirty-four pages of factory-correct part numbers, organized by subassembly, with original illustrations from 2011. If you’re working on a Roadranger RT-7608LL, this is the only parts reference you need on your bench. Access the Factory Manual and keep it in your shop tablet or print it out. One wrong part costs you more than the price of this document – and the right part starts with the right number.
