To fit Operation 3-5
1 Put the push rods and the rocker shaft assembly in position. Check that the push rods fit correctly in the
sockets of the tappets. Check that the ends of the adjustment screws fit correctly in the sockets of the push
rods.
2 Inspect the cylinder head setscrews for damage and excessive wear. Renew any setscrews that are
damaged or excessively worn.
3 Lightly lubricate the threads and the thrust faces of the cylinder head setscrews with clean engine lubrication
oil.
Warning! Ensure that there is no lubricating oil in the holes for the cylinder head setscrews. If there is oil in
these holes, the cylinder block could be damaged by hydraulic pressure when the setscrews are tightened.
4 Engage all the setscrews in their correct positions, except the setscrews at each end of the shaft, and tighten
them finger tight.
5 Ensure that the rocker shaft is in the correct position when the setscrews are tightened. To do this:
l
Put a 0,13 mm (0.005 in) feeler gauge (A2) between the rocker lever (A3) for the inlet valve of number one
cylinder and the first mounting bracket (A1) of the rocker shaft
l
Put another 0,13 mm (0.005 in) feeler gauge between the rocker lever for the exhaust valve of number six
cylinder and the last bracket of the rocker shaft
l
Fit the end setscrews, and tighten them finger tight.
6 Tighten the setscrews in the correct sequence and to the correct torque, see Operation 3-9. Check for free
movement of the first and last rocker lever.
7 Remove the two feeler gauges.
8 Check the valve tip clearances, see Operation 3-21.
9 Fit the rocker cover, see Operation 3-2.
