Oilless Reciprocating Air Compressor Pumps

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 pis-

ton 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

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.

* FOR LOW PRESSURE PISTON ONLY
