Removed the pressure line from the head to the tank, removed the 4 allen bolts holding the head and valve plate to the cylinder.
Set that all aside, and loosened the allen bolt and nut holding the connecting rod to the eccentric on the electric motor.
Slid the connecting rod off the bearing at an angle, then pushed the piston and rod up through the cylinder, taking the cylinder sleeve with it out.
Then reassembled the assembly with the new parts, in reverse order.
buttoned up the shroud and unit tested out just fine.
Make sure that when you put the valve plate back on under the head assembly to get the intake and the exhaust valve plate in the right direction, or there will be no way for the compressor to build the pressure it is designed for. You will hear a distinct noise if the valve plate is put on in the wrong direction.
