Description

Cummins 6BT-5.9 Screw Compressor Parts Catalog – Document 3249979 / SO42047

The Cummins 6BT-5.9 Screw Compressor Parts Catalog is the illustrated parts reference for the 6BT-5.9 screw compressor engine, published as document number 3249979 under reference SO42047. Every group in the engine is broken out into an exploded illustration and a matching parts list that gives the Cummins part number, the description, the quantity required and whether the item is serviceable. That combination is what makes this PDF useful at the bench: you can see where a component sits in the assembly, confirm it against the drawing, and order the right number without a second trip to the dealer.

The catalog follows Cummins’ standard indentation method, so sub-level components sit to the right of the assembly that contains them. Order the top-level bill of material and you receive everything beneath it, or order any sub-assembly or individual part on its own. Part numbers in brackets are the service replacement numbers and are the ones to order against; items marked with an asterisk are not sold separately and must be purchased through the assembly above them.

How the Parts Lists Are Laid Out

Every group table follows the same four-column format: S No, Ref No, Part No, Description, Qty and Serviceable. The Ref No matches the callout on the facing exploded drawing, so you can start from either end – find the number on the illustration and read down, or look up a part in the list and find it on the drawing. Where a part has a superseded number, the catalog notes it in the remarks column so you can order the current replacement rather than an obsolete one.

Why This Cummins 6BT-5.9 Parts Catalog Belongs in Your Workshop

Rebuilding, resealing or simply refreshing a 6BT-5.9 screw compressor engine means matching a lot of small components to a lot of small locations, and a parts list without the drawings leaves you guessing. This catalog gives both. You can identify the correct gasket for a water inlet connection, confirm the right cap screw length for a cylinder head, check whether a plug is a pipe thread or an expansion type, and see whether the banjo connector on a fuel line takes one sealing washer or two – all without pulling the assembly apart first.

For a parts counter, a fleet workshop or an owner doing their own maintenance, having the Cummins 6BT-5.9 Screw Compressor parts manual on hand turns a vague order into a precise one. Quantities per assembly are listed, so you know how many main bearing caps, how many valve collets, how many exhaust manifold gaskets or how many hex flange head cap screws a job actually needs before you start.
