REMOVAL AND INSTALLATION
Camshaft Bearings
Removal
1. Remove engine (6007) from vehicle as outlined in this section.
2. Place engine on work stand and remove camshaft (6250), crankshaft (6303) and camshaft rear
bearing cover.
3. Remove camshaft bearing with Camshaft Bearing Set T65L-6250-A.
4. 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.
5. Assemble 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 bearing or journal. Tighten the puller nut
against the thrust bearing and pulling plate to remove camshaft bearing. Be sure to hold the end of
the puller screw to prevent it from turning.
6. Repeat above step for each bearing. To remove the camshaft bearing, install the puller from the rear
of the cylinder blocks (6010).
Installation
The camshaft bearings are available pre-finished to size and require no reaming for standard and 0.38mm
(0.015 inch) undersize journal diameters.
CAUTION: Failure to use the correct expanding collet can cause severe bearing damage.
1. NOTE: Align the oil holes in the bearings with the oil holes in the cylinder block before
pressing bearings into place. Make sure the front bearing is installed 0.51-0.89mm (0.020-0.035
inches) below the front face of the cylinder block.
Position new bearings at the bearing bores and press them in place with Camshaft Bearing Set T65L-
6520-A. Be sure to center the pulling plate and puller screw to avoid damage to the bearing.
2. Install camshaft rear bearing bore plug as outlined in this section.
3. Install camshaft, crankshaft, flywheel (6375) and related parts. It is not necessary to check connecting
rod and main bearing clearances as part of camshaft bearing replacement.
4. Install engine in vehicle as outlined in this section.
