Removal & Installation: Crankcase: Reassembly

1. Before reassembly, check for loose or bent stud bolts. When replacing stud bolts, coat threads with a torque-holding sealant (Loctite 270) before installation. Check crankcase-to-cylinder head mating surface for warpage, and correct by grinding if necessary. Warping limit is .002" (.05 mm).
2. 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.
3. Clean mating surfaces of crankcase and apply liquid gasket. Install "O" ring and backup ring on the crankcase half having No. 2 and No. 4 cylinders. Reverse disassembly procedure. Tighten crankcase halves and cylinder heads in sequence shown in Figs. Figure and Fig 1 .

NOTE: Torque varies with bolt size.
