Start By:a. remove camshafts 1. Install tooling (A) as follows:a. Install the cam bearing pilot in the camshaft bearing.b. Put the backup plate in position so the bearing is between the parts.c. Install the bolt to hold the tooling together. 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 tool (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 bolt 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 Group) 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° 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. 5. 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. b. Follow Steps 2, 3 and 4 to install the tooling, and pull the bearing into the center of its bore.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 camshaftsRemove Crankshaft
Start By:a. remove rocker shaft assemblies and push rodsb. remove front drive housingc. remove front balancer group (3508)d. remove rear gear group (Step 1 only)e. remove piston cooling jets
The rocker shaft assemblies and push rods do not have to be removed to remove the crankshaft but bent push rods can be the result if they are not removed.
1. Put the engine in the position as shown. The weight of the 3516 Engine is approximately 7763 kg (17,114 lb.). The weight of the 3512 Engine is approximately 5443 kg (12,000 lb.). The weight of the 3508 Engine is approximately 4445 kg (9800 lb.). The counterweights do not have to be removed from the crankshaft if the piston and connecting rod assemblies have been removed from the engine. 2. Put identification marks on counterweights (1), and remove them from the crankshaft. 3. Remove bearing caps (2) from the connecting rod, and push the connecting rods away from the crankshaft. Use wire to hold the upper half of the connecting rods away from the crankshaft. 4. Remove the center main bearing cap, and remove two thrust plates (3) from each side of the main bearing. 5. Use two of the bolts that hold the flywheel to the crankshaft, and install a bolt in each end of the crankshaft. Fasten a hoist to the crankshaft as shown.6. Remove the remainder of main bearing caps (5), and remove crankshaft (4) from the cylinder block. The weight of the 3516 Engine crankshaft is 726 kg (1602 lb.). The weight of the 3512 Engine crankshaft is 549 kg (1201 lb.). The weight of the 3508 Engine crankshaft is 363 kg (801 lb.). 7. If necessary, remove bolts (7) to remove gears (6) from each end of the crankshaft.Install Crankshaft
If main bearing clearances or crankshaft end play is to be checked, see Install Crankshaft Main Bearings.1. If gears (1) were removed, install gears (1) on each end of the crankshaft, and install the bolts to hold the gears. 2. Make sure the upper halves of main bearings (2) (bearings with oil holes) are in position in the cylinder block. Put clean engine oil on the bearings. 3. Fasten a hoist to crankshaft (3) with two flywheel bolts, and put it in position. Make sure the word "FRONT" on the end of the crankshaft is toward the front of the cylinder block.4. Make sure the lower halves of the main bearings are in position in the main bearing caps. Put clean engine oil on the bearings, and install all but the center main bearing cap on the cylinder block. The caps must be installed with the word "FRONT" and the cast part number toward the front of the cylinder block. Each cap has a
