Roadranger RTLO-14613B 2011 Parts Catalog – OEM Factory Document

If you’ve ever had a transmission torn down on the bench, waiting on a part number because an aftermarket catalog gave you the wrong one, you know the exact frustration I’m talking about. That wasted time burns money, and in a shop like mine, every hour counts. That’s why I only use factory documents when I’m ordering parts for a Roadranger RTLO-14613B. This 2011 Parts Catalog from Roadranger is the real deal — 38 pages of OEM part numbers, exploded views, and kit breakdowns that match what actually came on the transmission from the factory. No third-party reprints, no re-labeled illustrations. Just the original document.

How To Use The Illustrated Parts List – Page 3

The first thing you need to understand is how this catalog is laid out. Page 3 explains the illustrated parts list system — each major assembly is shown as a figure with callout numbers. You match the number to the part description, and you get the exact Roadranger part number. That sounds simple, but if you’ve wrestled with a generic catalog that groups unrelated parts, you’ll appreciate this. Every callout is tied to a specific revision code, so you know if the part changed mid-production. That’s something aftermarket parts books regularly screw up.

AUXILIARY DRIVE GEAR – Page 4

Page 4 covers the auxiliary drive gear assembly. If you’re rebuilding the RTLO-14613B and need the drive gear, countershaft, or associated bearings, this page gives you the breakdown. The catalog separates the main transmission from the auxiliary section, which is smart because these two sections use different oil types and seal kits. Don’t mix them up — the auxiliary drive gear has a different tooth count than the main drive gear. The catalog lists it clearly with the correct part number.

H & C W/19470 Valve – Page 12

One of the most common problems on these Roadranger transmissions is air system leaks at the range cylinder or the H& C control valve. Page 12 covers the H & C with the 19470 valve assembly. If you’re replacing a shift valve or rebuilding the air manifold, this page shows every o-ring, plunger, and spring. I’ve seen aftermarket diagrams leave out the small nylon spacers that are critical for proper valve stroke. This catalog includes them. Check the revision code on the valve body — the 19470 and A-5000 valves (page 13) have different porting. This catalog distinguishes them.

KITS & ASSEMBLIES – Page 18

Page 18, KITS & ASSEMBLIES, is where you save real money. Instead of ordering individual seals, gaskets, and snap rings, Roadranger bundles them into overhaul kits with a single part number. The catalog lists the kit contents and the specific transmission serial number range it fits. I’ve had a guy bring me a “universal” rebuild kit from a parts house, and it was missing the countershaft rear bearing race. That race is page 9 item 12 in this catalog. When you buy by factory kit number, you get every piece in one box. No guesswork.

ROADRANGER VALVES – Page 31

The valve section on page 31 covers the full lineup of Roadranger valves used on the RTLO-14613B, including the range, splitter, and Hi-Lo valves. Each valve is shown with its mounting bracket, air lines, and solenoid if equipped. If you’re diagnosing a shift issue, start here. The catalog gives the part number for the complete valve assembly and for individual internal parts. You can order just the shift button or the entire air manifold.

Why Factory Documentation Over Aftermarket?

Aftermarket parts catalogs for Roadranger transmissions often reuse illustrations from earlier models, leaving out the updates made in 2011. The RTLO-14613B uses a specific input shaft and drive gear (page 14) that changed in the 2011 production year. If you order based on an older catalog, you’ll get the wrong spline count. This factory document was printed July 2011 — it matches what’s on the truck. There’s no substitute for the original publication. For a deeper understanding of how the transmission integrates with the drivetrain, see Automotive Industry Overview.

Related Manuals You Might Need

If you’re working on other Roadranger models, these factory parts catalogs follow the same format:

• Roadranger RTLO-14918B 2011 Parts Catalog – OEM Factory Document
• Roadranger RTLO-18918B-T2 2011 Parts Catalog
• Roadranger RT-8608L 2011 Parts Catalog

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. It lists part numbers, quantities, and illustrations. For torque specs you need the factory service manual.

Is this catalog specific to the RTLO-14613B only?

Yes. It covers the RTLO-14613B transmission produced in 2011. Do not use it for other models like the 14918B or 18918B-T2 – those have different part numbers for the mainshaft and synchronizer assemblies.

How many pages does the PDF have?

38 pages. Every page is scanned from the original printed catalog. You get the full contents from “How To Use The Illustrated Parts List” through the “ROADRANGER VALVES” section and the index.

Can I use this catalog for older RTLO transmissions built before 2011?

Not reliably. Roadranger made running changes to the input shaft and reverse idler gear in 2011. The 2011 catalog reflects those updates. If your transmission is a 2010 or earlier, the part numbers on pages 14 and 28 will likely be wrong. Check the serial number on your transmission tag and compare to the revision codes listed in the catalog.

Every time I order parts for a Roadranger, I pull up this catalog. It saves me from buying a seal kit that doesn’t fit and from sending a tech back to the parts counter. If you want to stop wasting time on mismatched parts, Access the Factory Manual from AutoRepairManuals today.
