Eaton FS-4005B 2011 Parts Catalog – OEM Illustrated Parts List

Description

Ever pull a transmission apart and find a bearing that’s stamped with nothing but rust? Or order a shift fork from a generic catalog and get the wrong dog engagement? I’ve been there. On a Roadranger FS-4005B, that mistake costs you a whole afternoon and a pissed-off fleet manager. That’s why you need the Eaton FS-4005B 2011 Parts Catalog — not a third-party reprint, not a blurry scan from some forum. This is the factory file: 18 pages of OEM part numbers, exploded views, and kit groupings that Eaton themselves used in July 2011.

How To Use The Illustrated Parts List – Page 3 Matters

Before you start flipping pages, read the instructions on page 3. Eaton spells out exactly how they label model designations and how kits and assemblies are organized. There’s a note about visiting roadranger.com for the latest EPC, but this paper version gives you the baseline. A- prefix part numbers? Those are pre-assembled production assemblies, not something you can buy separately as a loose part. K- prefix? Those are the kits you want for a clean overhaul. Ignore that distinction and you’ll be ordering individual bearings that don’t come with snap rings.

CASE and COUNTERSHAFT: Where Most Mistakes Happen

The CASE section starts on page 4. Countershaft assembly is on page 6. If you’re rebuilding a FS-4005B that’s been sitting in a yard for ten years, you need those exploded views to match the old parts to new ones. The manual doesn’t give torque specs — this is a parts catalog, not a service manual — but it lists every bolt, bearing, and seal by OEM number. I’ve seen guys order a countershaft from a 2009 catalog because they thought “they’re all the same.” The 2011 revision changed the thrust washer thickness on this model. Don’t guess.

Kits & Assemblies – Page 8 Saves You Phone Calls

Page 8 lists the KITS & ASSEMBLIES group. These are your time-savers. Instead of sourcing a dozen individual parts for a shift bar rebuild, you order one kit number. But you have to know which kit fits your specific build date. This catalog shows you exactly which parts are included in each kit. If you skip this page, you might end up buying a mainshaft kit that doesn’t include the synchronizer springs you need. Then you’re waiting another three days for a second order.

Shift Bar Housing and Remote Control – Don’t Overlook These

Shift bar housing starts on page 15. Remote control on page 13. These sections are small — maybe two pages each — but they’re critical if you’re dealing with a stuck shift yoke or a broken air line bracket. The Remote Control section lists the lever assembly parts that commonly crack on high-mileage trucks. Page 9 covers LEVER ASSY specifically. If your truck has a range cylinder leak, you can cross-reference the shift bar housing gaskets here. Factory part numbers only — no aftermarket substitutions.

Source Validity: OEM vs Aftermarket – Why This Catalog Wins

I don’t trust anything that says “equivalent to OEM” unless I have the original part number in my hand. This catalog comes straight from Eaton’s 2011 print run. The page count is 18, not 20 with a blank copyright page. The bookmarks in the PDF match the printed sections. No third-party rewrite. If you’re running a shop that bills by the hour, one wrong part number costs you more than the price of this manual. And if you’re a home garage guy rebuilding a retired dump truck, the exploded views on page 4 through 15 will keep you from ordering a clutch housing that doesn’t fit your bellhousing pattern.

Does This Catalog Cover Fuel System or Engine Diagnostics?

No. This is a Parts Catalog for the FS-4005B transmission only. It does not include wiring diagrams, hydraulic schematics, or torque specs. It’s strictly part numbers, exploded illustrations, and kit groupings. If you need service procedures, look for the factory service manual. But if you’re rebuilding the transmission itself, this parts list is the only way to buy the correct Eaton parts without cross-referencing three different websites.

7 Sections You’ll Actually Use

The table of contents breaks the box into seven major assemblies: Case, Countershaft, Input Shaft, Kits & Assemblies, Lever Assembly, Mainshaft, and Reverse Idler Gear. Plus a Miscellaneous section on page 12 that includes the breather, drain plug, and nameplate. Every section has a grid with part number, description, and quantity. No fluff. If you can read a parts list, you can rebuild this transmission.

For broader background on heavy-duty transmission technology, you can read the Automotive Industry Overview or brush up on Internal Combustion Engine fundamentals. But for the FS-4005B, this is the only parts document you need.

Q1: Is this catalog in English?

Yes. The original file is English, with metric and imperial units for fasteners where applicable.

Q2: Does it include torque values for the FS-4005B?

No. This is a parts catalog, not a service manual. Torque specs are in the separate service manual. This document only provides part numbers and exploded views.

Q3: How do I know if a part number supersedes to a newer version?

Eaton does not publish supersession history in this catalog. You will need to check the online EPC at roadranger.com using the part number from this manual. However, the 2011 edition is the latest standalone print version for FS-4005B, and most parts are still current.

Q4: Can I print the PDF and take it into the shop?

Absolutely. The file is 18 pages, clear OCR text, and the illustrations are crisp. Print it, laminate the key pages, and toss it in your toolbox. I’ve got page 4 and page 11 hanging on my bay wall right now.

Stop wasting time trying to match beat-up parts to blurry online listings. Access the Factory Manual — the complete Eaton FS-4005B 2011 Parts Catalog — and get the right part number the first time. Your transmission will thank you, and so will your wallet.
