Camshaft Bearings

Tools Required:

 

Removal

  1. Remove the camshaft, flywheel and crankshaft. Push the pistons to the top of the cylinders.
  1. Remove the camshaft rear bearing bore plug. Refer to Section 03-00. Remove the camshaft bearings using Camshaft Bearing Set T65L-6250-A.
  1. Select the proper size expanding collet and backup nut and assemble on the expanding mandrel. With the expanding collet collapsed, install the collet assembly in the camshaft bearing. Tighten the backup nut on the expanding mandrel until the collet fits the camshaft bearing.
  1. Assemble the puller screw and extension (if necessary) as shown 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. Be sure to hold a wrench on the end of the puller screw to prevent it from turning.
  1. Repeat the procedure for each bearing. To remove the front bearing, install the puller screw from the rear of the cylinder block.



 

Installation

Camshaft bearings are available prefinished to size for standard and 0.38mm (0.015 inch) undersize journal diameters. The bearings are not interchangeable from one bore to another.

 CAUTION: Failure to use the correct expanding collet can cause severe bearing damage. Ensure front bearing is installed the specified distance below the front face of the cylinder block.

  1. Position the new bearings at the bearing bores with the oil holes aligned with the holes in the block, and press them in place with the tool shown. Ensure to center the pulling plate and puller screw to avoid damage to the bearing.
  1. Install the bore plug using Perfect Seal Sealing Compound B5A-19554-A (ESR-M18P2-A and ESE-M4G115-A) or equivalent. Refer to Section 03-00.
  1. Install the camshaft, crankshaft, flywheel and related parts. It is not necessary to check connecting rod and main bearing clearances as a part of camshaft bearing replacement. Install the engine in the vehicle.
