REASSEMBLY PROCEDURE
To reassemble the cylinder stroke limiter into the piston retaining assembly, follow the
procedure below. Numerical references in this procedure refer to Figure 2.
n
Remove the piston retaining nut (7) from the mounting post and set aside.
o
Flip over the spring carrier (4) and place the four low stop springs (5) into the four holes
on the bottom of the spring carrier (4) (the bottom of the spring carrier is the side
WITHOUT the white plastic ring).
p
Place the cylinder stroke limiter (6) into the center section of the spring carrier (4).
Be sure to orient the cylinder stroke limiter correctly: pointed end facing out in the
direction of the springs.
The cylinder stroke limiter floats with the cylinder and is thus part of the cylinder assembly
mass. Take care not to contaminate this part when handling it. It is preferable to avoid
contacting this part with bare hands.
