2. After bearing cools, use .002” feeler
gauge to make certain bearing is
seated and not cocked.
3. Install retaining ring (Item 26). Note:
allow shaft to cool completely.
4. Carefully inspect hook piston rings
(Item 5). Piston rings need to be
modified prior to installation. SEE
CHYPR-008 DRAWING FOR PROPER
MODIFICATION PROCEDURES.
Clean piston rings prior to installation.
5. Lube shaft diameter and hook piston
rings with Mobilfluid 424 or similar oil.
6. Visually inspect piston ring grooves on
shaft for any signs of contamination.
Using hands install hook piston rings
onto shaft in the configuration shown
below and close hooks once the rings
are installed on the shaft.
ATTENTION: the orientation of the
dimpled side of the rings are
extremely important. Spread rings
just enough to get into groove.
