Camshaft Bearing: Service and Repair
Replacement
REMOVAL
1. Remove engine. Place engine on work stand and remove camshaft, crankshaft and camshaft rear bearing cover.
2. Remove camshaft bearing with Camshaft Bearing Set T65L-6250-A.
3. Select proper size expanding collet and backup nut, and assemble on the expanding mandrel. With the expanding collet collapsed, install collet
assembly in the camshaft bearing, and tighten backup nut on the expanding mandrel until the collet fits the camshaft bearing.
4. Assemble pulling screw and extension, if necessary, and install on the expanding mandrel. Wrap a cloth around the threads of the pulling screw to
protect the bearing or journal. Tighten the pulling nut against the thrust bearing and pulling plate to remove camshaft bearing. Be sure to hold the
end of the pulling screw to prevent it from turning.
5. Repeat the previous step for each bearing. To remove the front bearing, install the puller from the rear of the block.
INSTALLATION
The camshaft bearings are available pre-finished to size and require no reaming for standard and 0.081 mm (0.015 inch) undersize journal diameters.
1. Make sure the front bearing is installed 0.51-0.89 mm (0.020-0.035 inches) below the front face of the cylinder block.
Position camshaft bearings at the bearing bores and press them in place with Camshaft Bearing Set T65L-6250-A. Be sure to center the pulling
plate and puller screw to avoid damage to the bearing.
Failure to use the correct expanding collet can cause severe bearing damage.
NOTE: Align the oil holes in the camshaft bearings with the oil holes in the cylinder block before pressing bearings into place.
2. Install camshaft rear bearing cover.
