| Camshaft Bearing Set | T65L-6250-A |
Removal
Remove engine from vehicle. Refer to Engine — Automatic Transmission or Engine — Manual Transmission in the Removal and Installation portion of this section. Mount engine on a workstand using Rotunda Engine Mounting Brackets 014-00932-1 or equivalent.
CAUTION: Use care when pushing pistons to top of cylinders to prevent damage to piston cooling oil jets (6C327). Use connecting rod installation guides (rubber hose) or equivalent to protect connecting rod bolts (6214).
Remove camshaft (6250), flywheel and crankshaft (6303). Push pistons to top of cylinders.
Using Camshaft Bearing Set T65L-6250-A, select proper size expanding collet and backup nut and assemble on expanding mandrel. With expanding collet collapsed, install collet assembly in camshaft bearing, and tighten backup nut on expanding mandrel until collet fits camshaft bearing.

| 2 | — | Expanding Collet (Part of T65L-6250-A) |
| 3 | — | Backup Nut (Part of T65L-6250-A) |
| 4 | 6A251 | Camshaft Bearing |
| 5 | — | Puller Screw Extension (Part of T65L-6250-A) |
| 6 | — | Pulling Plate (Part of T65L-6250-A) |
| 7 | — | Puller Screw (Part of T65L-6250-A) |

| 9 | — | Thrust Bearing (Part of T65L-6250-A) |
| 10 | — | Puller Screw (Part of T65L-6250-A) |
Assemble puller screw and extension, if necessary, and install on expanding mandrel. Wrap a cloth around threads of puller screw to protect front camshaft bearing or camshaft bearing bore. Tighten pulling nut against thrust bearing and pulling plate to remove camshaft bearing. Be sure to hold wrench on end of puller screw to prevent it from turning.
Repeat procedure for each camshaft bearing. To remove front camshaft bearing, install puller screw from rear of cylinder block (6010).
Installation
CAUTION: Failure to use correct expanding collet can cause severe camshaft bearing damage. Be sure front camshaft bearing is installed the specified distance below front face of cylinder block.
Position new camshaft bearings at camshaft bearing bores with oil holes aligned, and press in place with Camshaft Bearing Set T65L-6250-A. Be sure to center pulling plate and puller screw to avoid damage to camshaft bearing.
Make sure each camshaft bearing oil hole aligns with oil hole in camshaft bearing bore. Use a length of wire to verify oil hole alignment.
Install camshaft, crankshaft and flywheel (6375). It is not necessary to check connecting rod and main bearing clearances as a part of camshaft bearing replacement.
Install engine (6007) into vehicle.
