CAMSHAFT OIL CLEARANCE
1. Measure the I.D. of the camshaft bore on the crank-
case with an inside micrometer.
2. Measure the O.D. of the camshaft journal with an out-
side micrometer.
3. If the clearance exceeds the allowable limit, replace the
shaft.
►
CAMSHAFT ALIGNMENT
1. Support the camshaft's both end journals with V blocks
on a
fl
at table. And set a dial indicator with its tip on the
intermediate journal.
2. Rotate the camshaft on the V block and get the eccen-
tricity (half of the measurement).
3. If the eccentricity exceeds the allowable limit, replace
the camshaft.
►
CAM HEIGHT
1. Measure the height of the camshaft lobes at their larg-
est O.D. with an outside micrometer.
2. If the measurement is less than the allowable limit, re-
place the camshaft.
