Eaton Series 10 2004 Parts Catalog – Factory Parts Breakdown for Dual Displacement Steering

If you’re rebuilding an Eaton Series 10 2004 Parts Catalog dual displacement steering control unit and you don’t have the factory parts catalog, you’re flying blind. I’ve seen guys order parts off a third-party drawing and end up with the wrong gerotor set because the aftermarket didn’t label the number of teeth. That’s time and money wasted. This is the real deal – the 2004 Eaton Series 10 Parts Catalog, 20 pages of OEM data. No reprint, no copy. You get the same document Eaton shipped to dealers.

The Eaton Series 10 dual displacement unit is used in heavy-duty steering applications. Without the correct part numbers, you’ll be guessing on seals, shafts, and gerotors. This catalog shows you exactly what to order, down to the O-ring size. Page 3 has the ID tag identification – you must match your unit’s serial number to the correct parts. Skip that step and you’ll order the wrong kit.

Eaton Series 10 Parts Catalog: Tools and Preparation

Before you crack a line, read the Tools section (page 3 of the catalog). Eaton specifies a torque wrench for the control unit bolts – nothing from the hip. The manual also stresses cleanliness: wash all metal parts in clean solvent, use filtered compressed air to dry them (no paper towels or cloth – lint kills hydraulic systems). Lubricate new rubber seals with petroleum jelly. These aren’t suggestions; they’re the steps Eaton requires to validate a warranty repair.

Assembly Drawing and Parts List: Where Every Part Lives

Page 4 is the assembly drawing – a blown-up view of every component in the Series 10 steering control unit. The parts list on page 5 gives Eaton part numbers for each item, including the Gerotor Parts List. That’s the rotating group that often wears first. Having the exact part number means you don’t waste time cross-referencing aftermarket catalogs. The Gerotor Parts List breaks down the inner and outer rotor sets, so you order the right displacement match.

How to Order Replacement Parts Correctly?

There’s a dedicated section called How to Order Replacement Parts. It walks you through reading the ID tag on your unit – model number, serial number, manufacturing date. Page 3 shows a sample ID tag with callouts. If your unit has been painted over or the tag is missing, the manual tells you how to identify the unit by measuring the displacement port sizes. I’ve used this trick myself on old trucks where the tag was long gone.

Disassembly and Assembly: Factory Procedures

Disassembly runs from pages 7 to 10. It covers removing the end cap, extracting the spool and sleeve, and pulling the gerotor set without damaging the housing. Each step tells you which tool to use – for example, a brass drift to tap the sleeve. Assembly is pages 11 to 18, including seal installation diagrams. Torque specifications for the mounting bolts and end cap are listed in foot-pounds. The manual also includes a section on checking the gerotor clearance – something you won’t find in aftermarket summaries. Seal installation specifically warns against twisting the O-rings during installation.
