To quote from the Rover Service Letter Vol 2, No. 23 (Aug 67):
The timing hole in the flywheel has been repositioned, so that when
the flywheel locking peg is inserted the EP mark no longer lines up
exactly with the timing pointer.
This has been done for assembly purposes, and is a design feature to
ensure that the timing is correct after the timing chains have been
fitted, and the engine run under power when all backlash in the
timing mechanism is taken up.
It means the the procedure for valve timing and valve check9ng now
differ as follows:
(a) valve timing during assembly of chains or chainwheels, apply lock
to flywheel and camshafts as detailed in the Rover 200 Workshop
(b) Valve checking, after operational running, rotate engine until EP
mark on flywheel is in line with timing pointer. With No. 1 exhaust
valve fully open it should now be possible to insert the locking key
into the slot of the camshaft driving hub.
So, in a nutshell, assemble the engine using both locking devices and
check timing using only the cam locking key and the EP mark.
>Thank you Paul. I can currently lock the cam when the pointer is on
>(close) to EP, but it sounds like it would be best to have the cam
>locked when the pin can be inserted in the flywheel (pointer not
>aligned with EP mark).

>>No, that is how they All are.
>>Just lock em and set em.
>>One day I'll measure to see if the pointer really is that far out.
