Caterpillar 953D 2009 Parts Catalog – OEM Factory Specs

If you are ordering parts for a Caterpillar 953D 2009 Parts Catalog territory machine without the right catalog, you are gambling with your shop’s money. I have seen guys slap on a aftermarket water pump from a generic listing and it does not fit because the part number was off by one digit. Then the machine sits, the customer calls, and you eat the labor. This factory Parts Catalog kills that guessing. It gives you the exact group numbers and illustrations Caterpillar uses on the assembly line.

Published in May 2009 under document SEBP4455-17, this manual covers the 953D Track-Type Loader with serial numbers LBP1-Up (Machine), C6E1-Up (Engine), and 9JW1-Up (Ripper). It is 813 pages thick. That is not fluff – that is every bearing, seal, bracket, and hose listed in the same order the parts counter uses.

813 Pages of Factory Part Numbers

You get the full Parts Catalog for the 953D. The Table of Contents starts with General Information (page A5), Repair Alternatives (A8), Supplemental Coolant Additives (A9), Maintenance Parts (A10), and Index (A14). Then comes Machine Arrangement (Section 1), Engine Arrangement (Section 2), and the Basic Engine breakdown (Section 4) with 28 subgroups from Camshaft GP to Valve Mechanism GP. The Cooling System section covers radiator and hydraulic oil cooler groups. The Fuel System section includes the adapter GP for fast-fill fuel. Every page uses the same factory numbering system Caterpillar parts departments rely on. You do not need to cross-reference third-party catalogs.

What the Index Covers: A14 to Final Page

The Index at A14 lets you look up a part by description or group name in seconds. Need a piston and rod assembly? Flip to the PISTON & ROD GP listing – it is on the page referenced. The index covers every group: Engine AR-Primary, Installation AR-Engine, Lifting GP-Engine, Mounting GP-Engine, and Mounting GP-Engine & XMSN. No more flipping through paper manuals blind. This is the same system Caterpillar uses in their dealer network.

Basic Engine Group Breakdown – Camshaft to Valve Mechanism

Section 4, Basic Engine, is where you will spend most of your time. Subgroups include: CAMSHAFT GP, COVER GP-ENGINE, COVER GP-VALVE MECHANISM, CRANKSHAFT GP (page 20), CYLINDER BLOCK GP (21), CYLINDER HEAD AS (25), CYLINDER HEAD GP (29), DRAIN GP-ENGINE OIL (33), FLYWHEEL GP (34), GUARD GP-BELT (35), HOUSING GP-FLYWHEEL (36), HOUSING GP-FRONT (38), LIFTING GP-ENGINE (40), MOUNTING GP-ENGINE (42), MOUNTING GP-ENGINE & XMSN (43), PAN GP-OIL (44), PISTON & ROD GP (50), PLUG GP-ENGINE (51), PULLEY GP-CRANKSHAFT (52), ROCKER ARM GP (53), and VALVE MECHANISM GP (55). Each group has a clear illustration with callouts and the corresponding part numbers. If you are rebuilding a C6.6 engine, this is the only source that matches the hardware exactly.

Is There Torque Data in This Catalog?

Let me be straight: a Parts Catalog gives you part numbers and quantities, not torque specs. If you need cylinder head bolt torque or main bearing cap values, you need the corresponding Service Manual. But without the correct part numbers, the best torque wrench in the world is useless. This catalog tells you which seal kit, which O-ring, which gasket to order. Pair it with the factory service manual and you have a complete workbench solution.

Why OEM Documentation Beats Aftermarket for the 953D

Aftermarket parts catalogs often consolidate multiple model years into one generic listing. They drop superseded numbers or mix up LH and RH parts. Caterpillar’s own Parts Manual for the 953D is model-specific. It lists every part that was installed on the assembly line for that serial number range. If the part number changed during production, the catalog shows the effective date. That kind of detail keeps you from ordering a precleaner that does not fit the air cleaner group on a later machine. For anyone serious about keeping a track loader running, this is the only source.
