Camshaft Bearing
- Inspect camshaft for runout. If runout exceeds 0.0059" (0.15 mm), replace camshaft. Inspect camshaft journals and bearings for wear or damage. If clearance exceeds specifications, replace camshaft bearings and/or regrind camshaft. Bearings are available in standard 0.010" and 0.020" (0.25 and 0.50 mm) oversizes.

- Drive out camshaft rear expansion plug from cylinder block. Remove front and No. 2 bearing using Camshaft Bearing Remover (Tool 09215-60010). Place front and second bearing adapters against rear of respective bearing and place tool against front part of cylinder block.
- Insert replacer shaft into the 3 parts and screw retainer nut onto replacer shaft. Hold slotted part of shaft with wrench to prevent shaft from turning. Front and No. 1 bearings will be pulled out to front by screwing in retainer nut with another wrench.

- Remove No. 3 and rear bearing toward rear of block using tool in same manner as for front and No. 1 bearing. When installing new bearings, ensure that oil holes of bearing match up with oil holes in cylinder block.
- When new bearings have been installed, measure to obtain proper clearance. Only a very light cut is required to ream bearings to proper size. Coat rear expansion plug with sealer and reinstall plug in block.
