Eaton CL 450 (BR), CL 455 (BR), CL3905, CL551, FS 2305C (BR) Parts Catalog

If you are tired of chasing aftermarket part numbers that don’t line up with what you pulled out of the case, this 414-page Eaton CL 450 (BR), CL 455 (BR), CL3905, CL551, FS 2305C (BR) Parts Catalog is what you need on the bench. I’ve been wrenching on heavy-duty Eaton boxes for twenty-eight years, and every time I see a tech guessing at a bearing or freewheel selection, I know they are either wasting an hour on the phone or ordering the wrong part twice. This catalog hands you the factory OE numbers – no interpretation, no Chinese knock-offs.

Eaton CL 450 (BR) and Related Models – Parts Catalog Coverage

This manual covers the following Eaton transmission models: CL 450 (BR), CL 455 (BR), CL3905, CL551, and FS 2305C (BR). All five are in the same CV (commercial vehicle) duty class. The data runs from page 1 through page 414, but the parts listed are strictly for the gearbox internals – bearings, freewheels, and associated hardware. Do not expect wiring diagrams or shift-fork adjustment specs; this is a parts catalog, not a service manual.

Using the OE Number System on Page 1

Flip to page 1 and you will see a table listing the application (model), OE number, installation point, and alternative manufacturer numbers (INA, SAAM, FAG). For example, for the CL 450 (BR) the OE number is 3342147, which cross-references to KM802048.M80201 1. That is a tapered roller bearing set. For the CL 455 (BR) the same OE number appears – but always verify the installation point. Some bearings are used across multiple models; others are model-specific. Do not assume the same part fits without checking the OE column.

Freewheel Bearing Cross-Reference – Page 2 Entry

Page 2 lists a freewheel for the CL551 with OE number 235376, used in 1st, 2nd, and reverse gear. The catalog gives you the FAG number (F-66464) and the VRS spec (722 0497 00). If you are rebuilding a CL551 and the freewheel feels sloppy, look up that OE number and order the exact bearing. I have seen shops install a standard deep-groove ball bearing in place of a freewheel – that is a transmission failure waiting to happen. This catalog stops those shortcuts.

Why Factory Eaton Documentation Beats Aftermarket

I don’t trust third-party parts catalogs because they are often recompiled from outdated sources or missing critical revision dates. This is a factory Eaton publication, dated 01.03.2012. Each page includes the date and page number – authenticity you can take to a dealer counter. The OEM cross-references (INA, SAAM, FAG, K, TR1, etc.) are verified against Eaton’s engineering database. If you have ever tried to match a bearing to a FS 2305C (BR) using a generic interchange book, you know the frustration. This manual eliminates that guesswork.

414 Pages: What’s Inside This Catalog

The document breaks down parts by transmission model and installation position. You will find rows for freewheel assemblies, needle roller cages, and tapered bearing sets. Each row includes the OE number, type (e.g., K for needle cage, VRS for freewheel), and package quantity (VPE). For instance, on page 3 you see bearings for FS 5306A (BR) and FS 6205A (BR) models – all with cross-references. The same OE numbers appear across multiple Eaton models, which is useful when you have a core that could have been originally installed in a different housing. The 414-page count means you have every OEM part number for the gearbox internal components – no missing pages, no condensed versions.

Does this catalog include torque specs or repair procedures?

No. This is a parts catalog, not a service manual. It lists OE numbers and bearing types only.

How do I use the OE number to find a replacement part?

Look up the transmission model on the left column (e.g., CL 455 (BR)), then read across to the OE number column. Write down that number (e.g., 3342147). Then check the cross-reference columns for INA, SAAM, or FAG numbers if your supplier stocks those brands. If your parts vendor needs the Eaton OE number, give them that directly. The catalog also includes the installation point (e.g., “CV” for constant velocity or “Freewheel”) so you can confirm the part location in the gearbox before ordering. This saves you from buying a bearing that fits the shaft but not the housing – a mistake I have seen new guys make with Eaton transmissions.

If you work on any of these Eaton CV transmissions – CL 450 (BR), CL 455 (BR), CL3905, CL551, or FS 2305C (BR) – this factory parts catalog belongs on your tablet.
