Installing the Wash Housing
Before installing the wash housing, ensure that
 The large washer is installed on the piston and pushed all the way back
 The wash housing seal is installed in the wash housing
To insert the wash housing
1. If you removed the left wash housing check valve see To replace the wash
housing check valves on page 173 .
2. Reinstall the wash housing O-rings if you removed them. Ensure the O-rings are
fully inserted into the O-ring grooves.
3. Identify the left and right wash housings. Remove a fitting on one of the wash
housings. If the fitting is a check valve then the housing is the left housing. If the
fitting is hollow then the housing is the right housing.
Tip: You might have labeled the wash housings Left and Right in the
section To remove the wash housing on page 169 .
