While using the machine, it started making a strange noise and refused to develop pressure.
Using a socket drive I disconnected the high pressure hose exiting the motor/pump cover going to the one way check valve mounted on the tank.
Using a Philips head screwdriver, I removed the two screws holding the housing in place near the tank brackets.
Using a torx driver I removed the screws holding the two motor/pump cases together, pushed the assembly forward from the mounting brackets and then separated the plastic cases.
There are rubber mounting feet placed at various locations keeping the pump and motor mounted to the plastic cases. Be certain to retain all of these square feet. If one or more are lost, they are available at this site as a separate part number.
Once again, using a nut driver, I removed the pump head (four screws) and separated the gaskets, valve assembly and O-ring. This is when I discovered the missing piece of head gasket. As the parts were so inexpensive, I ordered everything except the head casting itself.
The gasket kit I received had a replacement gasket to go with the new valve assembly that no longer used the O-ring. The gasket kit contained an O-ring had I used the old valve assembly.
Installing the head required using a cross-tightening pattern for installing the head bolts. As I had no specifics regarding the actual torque suggested for the head bolts, I tightened them to a level I thought appropriate without stripping the cylinder threaded holes.
Re-assembly was a reversal of the process listed above.
Silly me! Had I known the repair was going to be successful, I would have ordered motor brushes as they are worn more than half way and are only another $20. Now I need to order additional parts and separate the motor/pump casing halves again in order to replace the brushes.
