    • There are two versions of the unloader assembly:

    • First image—earlier pressure washers feature an all-in-one assembly (part 8-0631) that’s easy to replace, but gave users the ability to break the pump.

    • Second image—later models use a tamper-proof, harder to remove unloader (part 8-0656), connected by a series of pipe fittings.

    • This guide is written for the tamper-proof unloader assembly.

    • If you need to remove an all-in-one style unloader, use a large adjustable wrench to unscrew the two large Banjo bolts. This will disconnect the unloader from the pump assembly.
