engine should not be at top dead centre.

it should be at 9 oclock on the pulley pointer ...its marked

then 6.5MM drill bit should be inserted into the back of the flywheel into a hiole that is drilled in the flywheel


then you should have your pulleys like this .

First picture:



The above illustration shows the crankshaft pulley index in the 9 O'Clock position. Then, pistons Nos. 1 and 4 will be at 90 degrees BEFORE TOP DEAD CENTRE and pistons Nos. 2 and 3 at 90 degrees AFTER TOP DEAD CENTRE. All four pistons will be at the same level in the cylinder bores. When 'timing' the engine prior to fitting the timing belt, that crankshaft index must be set like this.

Picture 2:



The INLET CAMSHAFT PULLEY (on the left) and EXHAUST CAMSHAFT PULLEY (right) need to be in this position. However, it's not as simple as that because there are TWO slots on the camshaft pulleys- see next pictures - and the correct slot must be selected..

Picture 3:



LHB10028 - EXHAUST PULLEY with its locking bolt removed to show that the slot marked 'EX' must be located over the roll pin.

Picture 4:



Again with bolt removed, INLET PULLEY LHB10029 with the Roll Pin located in the slot marked 'IN'. The roll pin is difficult to see but is in the slot marked "IN" if you look closely.

Picture 5:



This is how they should look with the timing belt in place and the CRANKSHAFT PULLY INDEX still showing the 9 O'Clock position - see Picture 1.

WARNING Before starting that engine, DOUBLE CHECK AGAIN that CRANKSHAFT pulley index is still in the 9 O'Clock position.

Pictures taken of the engine in my 1993 TomCat Turbo.

also turbo puleys are not interchangeable, the one marked lhb10028 must go on the inlet cam and the lhb10029 must go on exhaust cam. in the correct roll pins slots aswellhth

I would take MGJohns to be right
My copied version of Johns post has been a sticky in rovertech for a long time ..
if it was the wrong info someone would have corrected him by now ..
My engine is running and was built with the aid of johns info .
