Timing gears - refit
1. Clean gear locations on camshaft and
crankshaft, fit Woodruff keys.
2. Check camshaft Woodruff key is fully engaged
in keyway.
CAUTION: Space between Woodruff key
and keyway acts as an oil feed. It is
therefore most important that key is
properly seated and parallel to axis of camshaft.
Overall dimension ’A’ must not exceed 30.15 mm
(1.2 in).
3. Temporarily fit crankshaft gear, and if
necessary turn crankshaft to bring timing mark
on gear to the twelve o’clock position, remove
gear.
4. Temporarily fit camshaft gear with marking ’F’
facing forwards.
5. Turn camshaft until mark on camshaft gear is
at the six o’clock position, remove gear without
moving camshaft.
