2. Install the thrust half ring to adjust the axial clearance of the camshaft.
3. Lubricate the camshaft journals and lobes with clean engine oil and install the camshaft into the cylinder head so that the groove on the front flange faces upward.
4. Install the camshaft bearing caps and tighten the cap mounting bolts in the following sequence.
Four-cylinder engines
1. Tighten bearing cap bolts #2 and #4 in a diagonal sequence, turning each bolt one-half turn at a time until each cap contacts the cylinder head. Then tighten the bolts in the same sequence in several stages to the specified torque. Gradual and uniform tightening of the bolts is necessary to ensure uniform compression of the valve springs.
2. Similarly tighten the camshaft bearing cap mounting bolts No.1, 3 and 5.
Five-cylinder engines
1. Tighten bearing cap bolts #3, #4 and #5 in a diagonal sequence, turning each bolt one-half turn at a time until each cap contacts the cylinder head. Then tighten the bolts in the same sequence in several stages to the specified torque. Gradual and uniform tightening of the bolts is necessary to ensure uniform compression of the valve springs.
2. Similarly tighten the camshaft bearing cap mounting bolts No.1, 2 and 6.
Six-cylinder engines
1. Tighten bearing cap bolts #2, #3, #4 and #7 in a diagonal sequence, turning each bolt one-half turn at a time until each cap contacts the cylinder head. Then tighten the bolts in stages to the specified torque in the same sequence. Gradual and uniform tightening of the bolts is necessary to ensure uniform compression of the valve springs.
2. Similarly tighten the camshaft bearing cap mounting bolts No.1, 5 and 6.
3. Install the camshaft sprockets.
