(1) Measure the depth “Al” (From the mating surface to the inner race of the ball bearing.)
(2) Measure the height “BI” (From the mating to the crank gear.)
(Al+ 0.3) - Bl=SIDE CLEARANCE (mm)
(SIDE CLEARANCE) - 0.2=THICKNESS OF CRANKSHAFT SHIM (mm)
(A+ 0.0123 -’ Bl=SIDE CLEARANCE (in)
SIDE CLEARANCE - 0.008”=THICKNESS OF CRANKSHAFT SHIM (in)
5-4-7-2 CAMSHAFT END PLAY (Model B=2:1 Reduction type only)
(1) Measure the depth “A2” (From the mating surface to the inner race of the camshaft bearing.)
(2) Measure the weight “B2” (From the mating surface to the camgear inner boss.)
(A2+ 0.3) - B=SIDE CLEARANCE (mm)
(SIDE CLEARANCE) - 0.2=THICKNESS OF CAMSHAFT SHIM (mm)
(A2+ 0.012”) - B=SIDE CLEARANCE (in)
SIDE CLEARANCE - 0.008”=THICKNESS OF CAMSHAFT SHIM (in)
