Removal
With engine (6007) removed and placed in a work stand, remove the camshaft (6250) crankshaft, and flywheel (6375). Refer to Camshaft and to Flywheel in the In-Vehicle Service portion of this section. Push pistons to top of cylinders.
Remove the camshaft rear bearing cover (6266). Refer to Engine Block Plugs service procedure in Section 03-00.
Using Camshaft Bearing Set T65L-6250-A, select the proper size expanding collet and backup nut and assemble onto expanding mandrel. With the expanding collet collapsed, install the collet in the camshaft bearing. Tighten backup nut on expanding mandrel until collet fits camshaft bearing.
Assemble the puller screw and extension (if necessary), as shown, and install on expanding mandrel. Wrap a cloth around threads of the puller screw to protect the front camshaft bearing or journal. Tighten pulling nut against the thrust bearing and pulling plate to remove camshaft bearing. Hold a wrench on the end of puller screw to prevent it from turning.
Repeat the procedure for each camshaft bearing. To remove the front camshaft bearing, install puller screw from rear of cylinder block (6010).
Installation
CAUTION: Failure to use correct expanding collet can cause severe bearing damage. Align oil holes in camshaft bearings with oil holes in cylinder block before pressing them into block. Be sure front camshaft bearing is installed 1.0-1.5 mm (0.040-0.060 inch) below front face of cylinder block.
Position new camshaft bearings at bearing bores, and press in place with the tool. Be sure to center the pulling plate and puller screw to avoid bearing damage.
Install a new camshaft rear bearing cover. Refer to Engine Block Plugs service procedure in Section 03-00.
Install camshaft, crankshaft (6303), and flywheel. Refer to Camshaft and to Flywheel in the In-Vehicle Service portion of this section.
