FLYWHEEL AS 2022381 - Caterpillar

Gasket kits are convenient items to have in a service shop. They eliminate part number research time, reduce clerical work, and lessen the chance for assembly errors. But, in some cases, service personnel are disappointed, either because certain gaskets were not included or several gaskets were left over in the kit after repairs. To avoid this, Caterpillar urges everyone to understand the consist list of each gasket kit before it is ordered. This is necessary to determine what each kit contains. This information is covered on the first few frames of the microfiche entitled Gasket Kit Usage Information. See Illustration 1. This fiche is presently updated every 60 days and included as part of the NPR library. Future updates will not be a part of the NPR library but instead will be sent with the Parts Book microfiche library.
Illustration 1. The Gasket Kit Usage Information fiche cross-references the kit part number to the engine model, engine arrangement number, and engine serial number.Gasket kit part numbers are listed on the microfiche according to engine model, engine arrangement and serial number. The different engine models are listed in order from smallest to largest (1100 Series appears first; D300 Series appears last). For each engine model, there are four sections which classify gasket kit part numbers by their location on the engine. You must know the engine model, arrangement number and serial number to obtain the part number of the needed gasket kit.
First, locate the engine model on the microfiche. Next, check the location classification which lists the part number of the correct gasket kit. Then match the engine arrangement and serial number to the column containing the kit part number. See Illustration 2.
A complete engine overhaul requires four basic kits - upper, central and lower, front, and rear structures - plus individual kits for accessory components. Smaller repairs need specific kits only.
The following list shows where the kits are used in the engine, kits currently available, and what each kit contains.
