STEP 1: See Figure 1. After cover (1) is installed on weld ring (2) with hinge pin (3), position
cam levers (4) on cover and close cam at each hold-down position. Minimal friction
resistance between bottom of cam and top of wear plate (5) should be evident. See
(FIGURE 1)
STEP 2: Insure upper pivot pin is centered between cam lever "ears". Use socket wrench to
tighten cam adjustment bolt (6) on top until gasket and weld rings top surface make
contact at each of the six cam locations
STEP 3: To insure a good peripheral sea tighten each cam adjustment bolt (6) shown in
FIGURE 1 to 13 lbs-ft (up to 16 lbs-ft). Cam tightening order should be done in a star
pattern which is shown in FIGURE 2. Tighten starting with cam number 1 and move

Gaskets should be checked periodically for cuts or accumulation of
product and could result in sealing problems. Replace all damaged
gaskets.
Cam levers and wear plates need to be inspected for excessive wear in
the area where they make contact. If the cam lever opens easily with
minimal resistance, replace the worn components.
