FLUID SPECIFICATION CHART

Scheme 7

1. Inspect bearings for the following defects. Cratering - fatigue failure Spot polishing - incorrect seating. Imbedded dirt engine oil. Scratching - dirty engine oil. Base exposed - poor lubrication. Both edges worn-journal damaged. One edge worn - journal tapered or bearing not seated.

Scheme 8

Scheme 9

1. Position on a length of plastigage on the bearing cap. Insert the camshaft, without lubrication, into the cylinder head. Position a plastigage strip, which should be equal to the width of the bearing cap, on the bearing journal.
2. Install the camshaft bearing caps. For additional information, refer to .
3. Remove the camshaft bearing caps. For additional information, refer to .
4. Using the special tool, read off the measurement. Compare the width of plastigage with the plastigage scale. The value that is read off is the bearing clearance. If the values are not to specification install a new camshaft.

Scheme 10

1. Determine the diameter of the camshaft journals. Using a micrometer measure the diameter at 90 degrees intervals to determine if the journals are out-of-round. Measure at two different points on the journal to determine if there is any tapering. If the measurements are out of the specified range, install a new camshaft.

Scheme 11

1. Using the special tool, measure the end play. Slide the camshaft in both directions. Read and note the maximum and minimum values on the dial indicator gauge. End play = maximum value minus minimum value. If the measurement is out of specification, install new components.

Scheme 12

1. Measure the diameter (1) and diameter (2) with a vernier caliper. The difference in measurements is the lobe lift.

Scheme 13

1. Inspect camshaft lobes for pitting or damage in the active area. Minor pitting is acceptable outside the active area.
