INSPECTION & CLEANING

INSPECTION & CLEANING

Check the HP seat knife edge
orifice (cone) for damage prior
to assembly.

The pushrod assembly must be
inspected for corrosion on the shaft,
also any bending of the shaft.
If any damage is noted replace the shaft.

All threads are checked for damage, look for peeling
chrome and damage caused by crossed threads.
