• Part Number Index

Because this is a parts manual rather than a service manual, its purpose is component identification and ordering. Every system on the 938G is broken down into arrangement-level, group-level, and assembly-level exploded views, each tied to a numbered parts list that includes part number, quantity, part name, and where-used notes. Serial-number breaks are printed in the captions and notes so the correct part can be selected for a specific machine, engine, or transmission serial range.

What This Parts Manual Covers in Practice

The 938G parts book lets a technician, parts counterperson, or owner-operator look up the exact Caterpillar part number for virtually any serviceable component on the machine. It supports rebuild and overhaul planning by listing the internal pieces of major assemblies – cylinder head groups, piston and rod groups, crankshaft groups, transmission clutch packs, differential groups, axle housings, brake and planetary groups, hydraulic pumps, cylinders, and valves. It supports day-to-day repair work by listing filters, seals, gaskets, hoses, lines, fittings, electrical components, sensors, relays, lamps, switches, and operator-station parts. And it supports machine configuration work by documenting arrangement numbers for engines, transmissions, axles, and attachments so the correct variant can be identified.

Why Use the Caterpillar 938G Parts Manual

Ordering the wrong part for a wheel loader is expensive and time-consuming. Caterpillar serial numbers change mid-production, and the same visual component may have several part numbers depending on machine, engine, or transmission serial range. This Cat 938G parts catalog ties each part to the serial-number breaks shown in its captions and notes, so the correct number can be selected the first time. The exploded illustrations also show assembly order and orientation, which makes teardown and reassembly planning more accurate.

Delivery

The file is delivered as an instant PDF download after payment. There is no shipping, no waiting for a physical book, and no restriction on which device it is opened on – a workshop PC, laptop, tablet, or phone. Pages can be printed for use on the shop floor, so the relevant exploded view and parts list can sit next to the machine while work is being done. The complete Caterpillar 938G Wheel Loader Parts Manual stays on hand for any future parts lookup on the same serial range.
