cylinder engine as
this may prevent the setting pin from being tted, clean away the corrosion.

Drive Checking Timing
To check the engine timing is correct the Flywheel
Locking pin is used to clock the crankshaft at tdc no.1 Cylinder and the camshaft setting plate is tted to the exhaust
camshaft to check correct camshaft position. It will be necessary to use the crankshaft turning tool supplied in the
kit to turn the engine to fully insert the ywheel locking pin.
5. Flywheel Locking Pin
There is a sealing plug in the access hole where the Flywheel Locking Pin is inserted.
Remove the plug
and partially insert the pin into the access hole ready to locate the timing hole in the ywheel
as the crankshaft is turned to TDC. (Fig.5)
6. Crankshaft Turning Tool
6-1 The engine can only be turned at the crankshaft pulley. Fit (B) onto the heads of the
4x pulley retaining bolts and use a ratchet spanner in the square drive provided to turn the
crankshaft/engine. (Fig.6)
IMPORTANT: The engine should only be turned in the direction of normal engine rotation. It
MUST NOT be turned in the other direction. Fig.6 6-2 Slowly turn the engine to TDC No.1
cylinder, and fully insert the ywheel locking pin to locate the timing hole in the ywheel.
6-4 The timing marks on the camshaft gears must be aligned. (Fig.8)
7. Camshaft Setting Plate
7-1 The Camshaft Setting Plate is installed onto the "Flats" on the exhaust camshaft.
For the camshaft timing to be correct, the (K) must be in contact with, and sit ush on both sides, of the surface of
the cylinder head, without a gap. (Fig.9) Should the gear timing marks not align or the Camshaft Setting Plate not

6-3 The correct TDC position is con rmed by the camshaft lobes
on No.1 cylinder pointing slightly upwards at an angle and to
the left when viewed looking in a direction towards the back of the camshaft gears.
(Fig.7)
Note: It should also be possible to read the part numbers on
top of the camshafts. Fig.7
sit fully ush on the cylinder head, without a gap, timing adjustment will be required.
