17029 Mercury WASHER, CAP SPRING

start by:a) remove camshafts1. 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 parts of 8S2241 Tool Group) can be used with an 8H684 Ratchet Box 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.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).a) install camshafts REMOVE CRANKSHAFT
start by:a) remove rocker shafts 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
CAUTION The rocker shafts 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 shown. 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).2. Remove counterweights (1) 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 engine block. The weight of the 3512 Crankshaft is 454 kg (1,000 lb). The weight of the 3508 Crankshaft is 299 kg (660 lb). 7. If necessary, remove bolts (7) to remove gears (6) from each end of the crankshaft. INSTALL CRANKSHAFT
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 number on the bottom surface and must be installed in the same position as the correct number on the right side of the block pan rail.
CAUTION Do not use an impact wrench to tighten the bolts 180° 5° of a turn more.
5. Apply Bel-Ray Molylube 67700 on the main bearing cap bolts and tighten the bolts in number sequence as shown to a torque of 136 14 N m (100 10 lb.ft.). Then tighten each bolt in the number sequence as shown 180° 5° of a turn more. Refer to the following link for ordering: www.belray.com 6. Put clean engine oil on the thrust plates and install thrust plates (8) on each side of the center main bearing. Install the center main bearing cap and the bolts to hold it. Use the same procedure in Step 5 to tighten the bolts. See INSTALL CRANKSHAFT MAIN BEARINGS for the correct bearing clearance check and crankshaft end play.7. Remove the wire that holds the upper half of the connecting rods in position. Make sure the upper and lower halves of the bearings are in position on the connecting rods and the rod caps. Put clean engine oil on the bearings.
CAUTION Do not use an impact wrench to tighten the bolts 90° 5° of a turn more.
8. Put the connecting rods in position on the crankshaft. Install caps (9) in the same location as they were removed from with the number on
