REASSEMBLY
3. After cleaning the shell, piston, and cap thoroughly, assemble the
accumulator as follows:
a. Install new teflon back-up rings (19) and new seal
rings (20) in the grooves of the shell, with the
seal ring nearest the open end of the shell (16).
It is important that the teflon seal be installed
in the ring groove of the shell so that the open
ends do not catch on the threads of the steel cap
when it is threaded into 'the end of the shell.
Lubricate the seal ring and the sealing surface of
the end cap with engine oil before installing the
cap. Reverse positioning of the open ends of the
back-up ring can cause contact between the ends and
the cap itself. This can cause the back-up ring
to buckle and result in an improper seal ring seal
when the cap is threaded on the shell.
b. Install the fluid end cap (14) on the shell, being
careful not to damage the seal ring.
c.
Assemble a new seal ring (17) between the two new
teflon back-up rings (18), in the piston (15) ring
groove. To insure correct positioning of the seal
ring and the two teflon back up rings, it is
recommended that a suitable ring compressor with
a diameter capacity of 3-1/2 inches to 7 inches
and 3-1/2 inches high compression band be used.
