Urrggh sorry to bring up old thread but need assistance timing TDC.
Took head of VL RB30 had head done; machined cleaned; studs etc Put on new tensioner; water pump; and belt. Lined up bottom crank cog with mark(s) and TDC with cam mark (ensure both #1 valves closed) new belt on using correct belt direction and 2 yellow marks on belt (that are 53 tooth/spaces apart) that align with mark(s) on each gear. Tensioned belt all good.
But
Rotated engine with crank bolt and marks do not cycle back to alignment! Looks to be a few cogs out. It hasn't jumped teeth that I know of. Yet engine should repeat it's rotational sequence and marks should come back to TDC marked positions. It doesn't!
Sigh ...anyone?
edit:
Ahhh my stupidity...the belt marks will not line up after rotation but the CAM and crank relationship marks will .....and will be 53 cogs apart....I've answered my own question....I'll just go punch myself now.
