CAM LEVER ADJUSTMENT PROCEDURE

LM 20” MANHOLE ASSEMBLY

WITH ADJUSTABLE CAMS

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

sequentially to cam number 6.

NOTE (1): Gaskets should be checked periodically for cuts or accumulation of

product and could result in sealing problems. Replace all damaged

gaskets.

NOTE (2): 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.
