7 Tighten the setscrews, in the correct sequence, a further part of a turn according to the length of the
setscrews (refer to Operation 3-12 illustrations A or B). Short setscrews (S) must be turned a further 150° (2.5
flats). Medium length setscrews (M) must be turned a further 180° (3 flats). Long setscrews (L) must be turned
a further 210° (3.5 flats). A special tool (C) can be used for this operation.
Fit the tool between the socket and the handle. Position the stop (C1) against a suitable protrusion on the
cylinder head to prevent movement of the degree dial in a clockwise direction. Rotate the pointer to align with
the relevant angle on the degree dial for the length of setscrew. Tighten the setscrew until the pointer on the
tool is aligned with the zero position on the degree dial.
If no tool is available, make a suitable mark on the cylinder head in line with a corner of each setscrew (D).
Make another mark, at the correct angle (counter-clockwise), on the edge of the flange of each fastener
according to the length of the setscrew. Tighten each setscrew in the correct sequence until the marks on the
flange are next to, and in line with, the marks on the cylinder head.
8 Put the push rods in position. Ensure that the end of each push rod fits correctly in the tappet socket.
9 Fit the rocker assembly, see Operation 3-3.
10 Set the valve tip clearances, see Operation 3-6 for four cylinder engines or Operation 3-7 for six cylinder
engines.
11 Fit the atomisers, see Operation 11-5.
12 Fit the high-pressure fuel pipes; tighten the connection nuts to 22 Nm (16 lbf ft) 2,2 kgf m.
Caution: Where access to the fuel injection pump outlet unions is possible, ensure that a separate spanner
is used to prevent movement of the fuel injection pump outlets when the connections of the high pressure pipes
are tightened.
13 Fit the fuel filter and the bracket. Fit the low-pressure fuel pipes between the fuel injection pump and the
fuel filter.
14 Fit the coolant by-pass connection; tighten the setscrews and hose clip.
15 Fit the coolant temperature sender unit.
16 If a compressor is fitted: Fit the coolant pipe between the cylinder head and the compressor. Then fit the
pipe between the coolant by-pass and compressor.
17 Four cylinder engines: Fit the oil cooler if it is integral with the cylinder block, see Operation 12-22.
18 Fit the exhaust manifold, see Operation 3-10 or Operation 3-11.
19 Fit the intake manifold, see Operation 3-9.
