Disassemble plastic housing around compressor unit using appropriate tools. Remove the four bolts from the compressor head using a 5/16 nut driver. Carefully remove head assembly including airline. Remove bolt through rod bearing with Allen wrench.

Reassemble with new rod and piston assembly. Best to use blue locktite on bolt through rod bearing when reassembling. Make sure to torque all bolts to specs listed.
