Remove & Install Camshaft Bearings
*Part of 6V4077 Camshaft Bearing Tool Group.
**Part of 8S2241 Camshaft Bearing Installation And Removal Group.Start By:a. remove camshafts
Typical Example1. Install tooling (A) as follows:a. Install the cam bearing pilot in the camshaft bearing.b. Position the back-up plate so the bearing is between the parts.c. Install the bolt to hold the tooling together.
Typical Example Tooling (D) is used in place of tooling (B), and (C) to remove and install the camshaft bearings when the flywheel and front drive housings have been removed from the cylinder block.2. Install tooling (B) on the flywheel housing as shown, or install tooling (B) and (C) on the front drive housing. Tooling (C) must be used behind the holes for clearance to install tool (B) on the front drive housing.3. Use tooling (E) as needed to get the correct length. Connect the extensions to the stud on tooling (A). The threaded shaft, thrust bearing assembly and nut (all part of 8S2241 Camshaft Bearing Installation And Removal Guide) can be used with an 8H684 Ratchet Wrench in place of tooling (F) if a hydraulic puller is not available.4. Connect tooling (F) to extensions of tool group (E) and pull the bearing from its bore in the cylinder block. When the bearings are installed in the bore of the block, the bearing joint must be on the horizontal centerline of the bore and the upper oil hole of the bearing toward the vee of the block. The upper bearing oil hole must be put 20° 5° above the horizontal centerline of the bore in the block, and the location of the lower (outside or outboard) bearing oil hole will be (and must be) 20° 5° below the horizontal centerline of the bearing bore as shown. Also, the bearing joint of the right side bearings must be toward the vee of the block, and the left side bearings must be toward the outside of the block.
Typical Example5. Install the camshaft bearings as follows:a. Install camshaft bearing (1) on tooling (A) as shown, and put unit (2) in position in the bearing bore.
Typical Exampleb. Follow Steps 2, 3 and 4 to install the tooling. Pull the bearing into the center of its bore with tooling (B) and (F).c. Check the bore in bearing (1) after it is installed. The bore must be 86.00 0.06 mm (3.386 .002 in).End By:a. install camshafts
