    • 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.

    • Before you begin, be sure that the engine is powered off and is cool to the touch.

    • Grab the plastic housing at the end of the spark plug wire.

    • Pull firmly to disconnect the wire from the spark plug.

    • Look through the top access hole on the pump, near the engine coupling. You should be able to see the pump shaft through the hole.

    • Slowly pull the starter cable. This will slowly turn the engine's axle.

    • Keep rotating the axle until you can see the set screw through the access hole.

    • Use a 1/2" wrench to remove the four 30 mm long bolts which mount the pump to the engine.

    • You should still have the support block under the pump assembly to help bear the pump's weight.

    • Re-assembly tip: note how the washers are stacked when reinstalling the bolts.

    • Replace the lock washers with new ones.

    • Re-assembly note: To re-attach the motor:

    • Press the axle key into the notch on the engine axle.

    • Align the pump shaft with the keyed axle. You may have to rotate the pump to do so.

    • Slide the pump onto the axle until the coupling surfaces touch.

    • If there is a significant gap between the pump and engine, pull the pump off, and re-set the axle key.

Conclusão

To reassemble your device, follow these instructions in reverse order.

When you re-connect the fittings, clean off the old thread sealant and apply new thread sealant (tape or pipe dope).
