17A ENGINE TIMING
8 Rotate the crankshaft counter-clockwise
approximately 45°, then slowly clockwise to check
the timing again. Continue to rotate the crankshaft
clockwise and check the TDC position. If the timing
and the TDC are correct, remove the dial gauge
and the adaptor from the fuel injection pump and fit
the washer and the plug. Tighten the plug to 10 Nm
7 lbf ft (1,0 kgf m)
9 Fit all the pipes to the fuel injection pump.
Remove the dial test indicator from the cylinder
head and fit the valve springs and the rocker lever.
Set the valve tip clearance to 0,20 mm (0.008 in).
Fit the rocker cover, operation 12A-01.
10Eliminate the air from the fuel system, operation
20A-08A.
The procedure given below is suitable for
engines fitted with a Bosch EPVE fuel injection
pump which have a static timing of 9° or less.
1 Set the piston of number 1 cylinder to TDC on
the compression stroke, see operation 17A-01B.
2 Measure accurately clockwise around the outside
surface of the damper/pulley from the TDC mark
and make a temporary mark to indicate the static
timing angle, see data and dimensions.
Note: 1° is 1,8 mm (0.07 in) at the circumference
of a pulley of 203 mm (8 in) diameter. If a large
damper is fitted, 1° is 2,7 mm (0.106 in) at the
circumference of a damper of 310 mm (12.2 in)
diameter or 2,9 mm (0.114 in) for a damper of 327
mm (12.9 in) diameter.
If a pulley of a different size is fitted use the
formulae below to find the measurement for the
temporary mark for the static timing:
C x P
360
C = circumference of pulley or damper
P = Static timing angle, refer to the data and
dimensions
3 Remove the high-pressure pipes from the fuel
injection pump and fit the adaptor and dial gauge to
the rear of the pump, see paragraphs 2, 3 and 4 of
operation 17A-03.
4 Rotate the crankshaft counter-clockwise for 1/8
of a turn. Slowly rotate the crankshaft clockwise
until the timing mark on the damper/pulley aligns
accurately with the tip of the pointer. With the
crankshaft in this position, the timing is correct if
the dial gauge on the pump plunger indicates
1,0 mm (0.039 in).
5 If the timing is not correct see paragraphs 6 and
7 of operation 17A-03.
6 Rotate the crankshaft 1/8 of a turn counter-
clockwise, then slowly clockwise to align the timing
mark with the tip of the pointer and check the
timing again. If the timing is correct, remove the dial
gauge and the adaptor from the rear of the pump.
Fit a new washer and the plug and tighten the plug
to 10 Nm (7 lbf ft) 1,0 kgf m.
7 Fit the fuel pipes to the fuel pump. Remove the
temporary marks from the damper/pulley. Remove
the temporary pointer from the timing case. Fit the
rocker cover, operation 12A-01.
8Eliminate the air from the fuel system, operation
20A-08A.
