Camshaft Bearing: Service and Repair
Replacement
NOTE: Camshaft bearings are available prefinished to size for standard and 0.38 mm (0.015 inch) undersize journal diameters. The camshaft bearings
are not interchangeable from one bore to another.
REMOVAL
1. Remove engine from vehicle.
2. Remove the camshaft, flywheel and crankshaft. Push the pistons to the top of the cylinders.
3. Remove rear bearing bore plug.
4. Select the proper size expanding collet and backup nut and assemble on the expanding mandrel Camshaft Bearing Set T65L-6250-A.
5. With the expanding collet collapsed, install the collet assembly in the camshaft bearing, and tighten the backup nut on the expanding mandrel until
the collet fits the camshaft bearing.
6. Assemble the puller screw and extension (if necessary) and install on the expanding mandrel. Wrap a cloth around the threads of the puller screw
to protect the front bearing or journal. Tighten the pulling nut against the thrust bearing and pulling plate to remove the camshaft bearing. Make
sure to hold a wrench on the end of the puller screw to prevent it from turning.
7. Repeat the procedure for each camshaft bearing. To remove the front bearing, install the puller screw from the rear of the cylinder block.
INSTALLATION
1. Position the new camshaft bearing at the bearing bores with the oil holes aligned and press them in place with the Camshaft Bearing Set
T65L-6250-A. Be sure to center the pulling plate and puller screw to avoid damage to the camshaft bearing. Failure to use the correct expanding
collet can cause severe camshaft bearing damage. Make sure the front camshaft bearing is installed 0.127-0.508 mm (0.005-0.020 inches) below
