6  Remove new piston cup(s) from protective cardboard packaging. Set new piston cups 

onto retainer plate, these parts will sit flat against each other.

7  Press retainer plate with piston cup into cylinder all the way to the piston. The cylinder 

can be rotated to align the screw holes. Apply thread locking compound (Loctite

®

 222) 

to retainer screws, torque screws to 10-13 inch-pounds.

8  Remove the cylinder o-ring(s) from the bottom of valve plate(s) and install new o-rings.

9  Inspect leaf valves for damage or wear. NOTE: There is one intentionally “bent” leaf 

valve per set. If leaf valves need to be replaced, a complete leaf valve plate can be 

ordered. The screws holding the leaf valves are susceptible to breaking which makes 

individual leaf valve replacement very difficult. Complete valve plate assemblies:

  SRC25VP for SRC25 units; SRC50VP for SRC50 units.

10 Check that orientation of the valve plate(s) with ports is correct and place over  

cylinders.

11 Remove old and install new head o-rings in the o-ring grooves on top of valve plate.

12 Reinstall head over valve plate(s) checking that orientation with ports is correct. Torque 

screws to 50 inch-pounds. 

Check that all external accessories such as relief valves  

and gauges are not damaged before re-operating product.

* To troubleshoot low voltage, unit can be tried in an outlet closer to the breaker panel. Voltage drop 

in longer electrical runs can cause low voltage.
