SERVICING – THREE PISTON SYSTEM
Drain the remaining fluid from the cylinders.
Inspect both bores of the trim cylinders for exces-
sive scoring. If one or both trim bores are scored
or damaged, the hydraulic assembly must be

driver to carefully pry the scraper out of the end
cap. Discard the scraper.

and the outer O-ring. Discard the quad-ring and
O-ring.
