5.8 Replacing a Pump Piston
Continued leaking of the piston seal after installation of a new seal (assuming the
pump head is tight) indicates a dirty, scratched, or broken piston.
Follow the instructions in Section 5.7
to install a new piston (P/N 052840) and
piston seal (P/N 055870). Always replace the piston seal when replacing a piston.
After replacing the piston and seal, reset the seal wear and pump piston stroke
counters.
