Removal & Installation: Reassembly
- Before reassembly, check for loose or bent stud bolts. Use Stud Bolt Wrench (898878600) when replacing stud bolts. Coat threads with a torque-holding sealant (Loctite 270) and tighten to 25-33 ft. lbs. (24-44 N.m).
- Check stud bolt length. On 1.6L engines, length should measure 3.563-3.642" (90.5-92.5 mm), and on 1.8L engines it should measure 3.602-3.681" (91.5-93.5 mm). Check crankcase-to-cylinder head mating surface for warpage, and correct by grinding if necessary. Warping limit is .002" (.05 mm).
- Lubricate all friction surfaces with engine oil prior to reassembly. With bearings installed on the crankcase half having No. 2 and No. 4 cylinders, install crankshaft and camshaft so punch mark on camshaft gear is visible through chamfered hole in crankshaft gear. See Fig 2 .
- Clean mating surfaces of crankcase and apply liquid gasket. Install water jacket "O" ring and back-up ring into crankcase half having No. 2 and No. 4 cylinders. To complete reassembly, reverse disassembly procedure. Tighten crankcase halves and cylinder heads in sequence. See Figure and Fig 1 .
NOTE:
Torque varies with bolt size.
