2. Establish a persistent half ring for adjustment of an axial backlash of a camshaft.
3. Lubricate the camshaft journals and lobes with clean engine oil and install the camshaft in the cylinder head with the groove on the front flange facing up.
4. Install the camshaft bearing caps and tighten the cap bolts in the following sequence.
Four-cylinder engines
1. Tighten bearing cap bolts #2 and #4 in diagonal sequence by turning each bolt half a turn in one pass until each cap contacts the cylinder head. Then, in the same sequence, tighten the bolts in several stages to the required torque. Gradual and even tightening of the bolts is necessary to evenly compress the valve springs.
2. Tighten the camshaft bearing cap bolts No. 1, 3 and 5 in the same way.
Five-cylinder engines
1. Tighten bearing cap bolts No. 3, 4 and 5 in diagonal sequence by turning each bolt half a turn in one pass until each cap contacts the cylinder head. Then, in the same sequence, tighten the bolts in several stages to the required torque. Gradual and even tightening of the bolts is necessary to evenly compress the valve springs.
2. Tighten the camshaft bearing cap bolts No. 1, 2 and 6 in the same way.
Six-cylinder engines
1. Tighten bearing cap bolts #2, 3, 4 and 7 in diagonal sequence by turning each bolt half a turn in one pass until each cap contacts the cylinder head. Then, in the same sequence, tighten the bolts in several stages to the required torque. Gradual and even tightening of the bolts is necessary to evenly compress the valve springs.
2. Tighten the camshaft bearing cap bolts No. 1, 5 and 6 in the same way.
3. Install the camshaft sprockets.
