NOTE: The orientation in which the pistons are reinstalled is very impor- tant. Improper placement will cause premature wear of the ring and pis- ton.

NOTE: When removing HP piston on two-stage pumps, remove piston and then insert retention sleeve having the same diameter of piston pin or piston to small end of connecting rod. If not, you may drop or lose needles from the bearing, as HP needle bearing does not have support.

 

Fit piston by referring to ∆ marking on the top of the

! CAUTION

piston surface and list on above chart.

NOTE: Gradually insert piston pin while turning it. Inserting with force can damage oil seal of needle bearing.
