CAMSHAFT AND HYDRAULIC LIFTERS
Camshaft and Hydraulic Lifter Removal
1. Keep the timing marks (A) aligned during removal (Figure 13-46, Page 13-25).
2. With cylinder head removed, pull the hydraulic lifters out of their bores to the top of the cylinder. See
following CAUTION. See Cylinder Head on page 13-8.
3. Take the camshaft out of the engine block.
∆ CAUTION
• Do not depress the socket (1) (Figure 13-47, Page 13-26). This will cause the engine oil to leak out of
the high pressure chamber during storage. Keep the hydraulic lifters upright to prevent the engine oil
from spilling out of the lifters during storage.
• Do not attempt to disassemble a hydraulic lifter because the engine oil will drain out of the high
pressure chamber in the lifter.
Camshaft and Hydraulic Lifter Inspection
If the engine typically remains noisy for two minutes after it starts, the hydraulic lifter might be worn between
the plunger (2) and the body (3). Proceed with the following to check the hydraulic lifter for wear (Figure 13-
47, Page 13-26).
1. Put the hydraulic lifter vertically on a measuring stand to measure leak-down distance.
2. Push the socket (1) down and measure the distance that it sinks (Figure 13-47, Page 13-26).
3. If the distance exceeds 0.0197 inch (0.5 mm), replace both hydraulic lifters as a set.
4. Inspect the camshaft for wear or broken gear teeth.
5. Measure the camshaft journals and cam lobes with a micrometer at the points shown (Figure 13-48,
Page 13-26 and Figure 13-49, Page 13-26).
6. If the camshaft journal diameter is less than 0.9026 inch (22.927 mm) at either end of the shaft, replace
the camshaft.
