[ROVERNET - UK] From Steve Lawrence P6 timing

[Vern Klukas]

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 
manual.
(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.

Yours
Vern
