Camshaft Bearings

NOTE: Camshaft bearings (6261) are available prefinished to size for standard and 0.38mm (0.015 inch) undersize journal diameters. The camshaft bearings are not interchangeable from one bore to another.

Removal

1. Remove engine (6007) from vehicle. Refer to Engine—Except F150/250 with 5.0L and E4OD Transmission or Engine—F150 with 5.0L and E4OD Transmission in Removal and Installation portion of this section.

2. Remove the camshaft (6250), flywheel (6375) and crankshaft (6303) as outlined. Push the pistons (6108) 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. Be 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 (6010).

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 0.127-0.508mm (0.005-0.020 inches) below the front face of the cylinder block.

   

2. Install a new rear bearing bore plug.

3. Install the camshaft, crankshaft, flywheel and related parts as outlined. Do not check connecting rod and main bearing clearances as a part of camshaft bearing replacement. Install the engine in the vehicle.
