Camshaft timing

Method 1 (without equipment)
Figure 39
Determine top dead centre (TDC) for cylinder 1 proceeding
as follows:
- Rotate the crankshaft so that the piston for cylinder 1 is
close to TDC.
- Fit the dial gauge as illustrated in the diagram.
- Carefully determine TDC (the point at which the dial
gauge pointer stops).
Figure 40
Trace two marks, one on the crankshaft key (1) and one
reference one on the cylinder block/crankcase:
- Rotate the crankshaft until a movement of the pointer is
detected on the dial gauge and then make a second mark
on the crankshaft (2).
- Measure the halfway point between the two reference
marks and make a third reference mark (3) on the
crankshaft.

Figure 41
Check that TDC coincides with the mark made:
113060
- Rotate the crankshaft backwards.
- Rotate the crankshaft again, forwards, until the dial gauge
changes direction.
- Check that the point at which the dial gauge changes
direction (zero point on the dial gauge) coincides with the
reference marks made on the crankshaft andon the
cylinder block/crankcase.

- Fit the dial gauge on the exhaust tappet for cylinder no.
4.
- Search for the point at which the tappet on which the dial
gauge is fitted is fully lowered and zero the dial gauge.
