Crankshaft & Main Bearing Installation
WARNING: This page is about a different variant/trim than selected.
- Lubricate and install upper crankshaft main bearings into upper cylinder block. Lubricate and install crankshaft. Pry crankshaft rearward, and install lubricated upper thrust washer by rolling washer into machined groove between crankshaft and cylinder block.
- Lubricate and install lower crankshaft main bearings and crankshaft thrust main bearing onto lower cylinder block. Clean upper and lower cylinder block mating surfaces. Apply Black Silicone Rubber (F4AZ-19562-B) to specified areas on lower cylinder block. See Fig 1.
- Install lower cylinder block over alignment dowels and onto upper cylinder block. Install NEW lower cylinder block-to-upper cylinder block bolts No. 1-16. See Fig 3. Install remaining lower cylinder block-to-upper cylinder block bolts.
- Ensure stud bolts are used in correct locations for reassembly of oil pan baffle. See Fig 2. Tighten lower cylinder block-to-upper cylinder block bolts in sequence to 27-44 INCH lbs. (3-5 N.m). See Fig 3.
- Pry crankshaft rearward, and seat crankshaft thrust washer forward. Tighten bolts No. 1-8 to 18 ft. lbs. (25 N.m), in sequence. See Fig 3. Tighten bolts No. 9-19 to 30 ft. lbs. (40 N.m) in sequence. Tighten bolts No. 1-16 an additional 90 degrees in sequence. Tighten bolts No. 17-22 in sequence to 18 ft. lbs. (25 N.m).
- Ensure crankshaft rotates freely and end play is within specification. See CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS table under ENGINE SPECIFICATIONS. If end play is not within specification, check crankshaft thrust face or replace thrust bearing.
