Plastic Parts Kit PL72 ATC 1″ inch

This kit contains the oil deflector plastics which are essential for the transfer case’s health. They act as internal guides that catch and direct oil to the gears, chain, and bearings. Without these working properly, the internal components won’t receive the lubrication they need, leading to overheating and mechanical failure.

Common symptoms include a jerking sensation while accelerating, or unusual grinding noises coming from the drivetrain. Often, when these plastic parts become brittle or melt due to old oil, they stop directing lubricant correctly. If you are already rebuilding your transfer case because of a stretched chain, it is critical to replace these plastic parts at the same time.

The PL72 ATC transfer case comes in different configurations. This specific kit is designed for the version utilizing a 1-inch wide chain. We recommend checking your transfer case tag or measuring the internal components to ensure the 1-inch specification matches your unit before installation.

Mechanics generally advise against it. Over years of operation, these plastic components undergo thousands of heat cycles which make them brittle. They are prone to cracking during disassembly or shortly after a rebuild. Replacing them with a new kit is a cost-effective way to ensure the long-term reliability of your repair.

The installation itself isn’t complex, but it does require a complete teardown of the transfer case. These parts sit deep within the housing. If you are comfortable opening the case to replace a chain or clutch pack, installing these plastics is a straightforward step in the reassembly process.
