I'm reaching the point when I shall be reassembling my now-2200 engine, and I am puzzled by the wording in the factory workshop manual.
It says, to quote, 'On late models [like mine] 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 the backlash in the timing mechanism is taken up. It means that the procedure for valve timing during assembly of chains and chainwheels and valve checking after operational running now differ.'
The manual then describes how to check and re-set the valve timing, instructing us to position the EP mark in line with the pointer and making no mention of the locking key which, for the reason mentioned above, of course wouldn't fit anyway. Presumably this is the method for engines which have already been run and whose timing chains have been under load.
I'm building the engine from scratch, with new chains and tensioners. It seems that I should set the timing by using the locking peg, as implied in the first paragraph above. Am I right?
Many thanks for any advice.
