OK, so today's job was KR head onto 6A block. All went swimmingly until I fitted the clutch & flywheel. Twas at that point I realised I'd moved the crankshaft about a bit and as I hadn;t fitted the pulley I didn't have a clue what position the pistons were in. The head is fine, I haven;t fiddled with it and the inner and outer cam sprocket marks align where they should. The engine is in the shed with no gearbox so I have nothing to align the flywheel notch with. Is my only option now the screwdriver down no.1 spark plug hole jobbie? And it looks like the crank pulley had four holes for the notch so can be fitted in any position - is that right? Cheers.
the whole screwdriver thing is abit philistine like! Can you borrow a dti guage and use that? Should be a key on the crank pulley to align for one place?
Sorry, when I said notch I meant the raised bit on the crankshaft sprocket - is that what you mean by "key". On the reverse of the crank pulley there are four indents so that the raised bit/key can be fitted in any position - i.e. it don;t help none. BTW, What's a dti gauge?
Sean, you'll find that the crank pulley will only go on, and all the 4x 6mm allen bolts will only line up/screw in, in one place. I use the screwdriver on top of no.1 position method as did Vince @ Stealth when checking my cam timing. DTI (dial,test,indicator) is a special gauge fitted with a plunger that shows movement in parts on an analogue scale.
As I said to someone on here last night, the screwdriver/knitting needle approach sounds inaccurate but you can't be half a tooth out on the cam belt so as long as you pay attention you should get it bang on or 1 tooth either way, which you'll notice. The poor man's dial gauge is accurate enough for this job.
the intermediate shaft only runs the oil pump, so no it doesn't matter. (edit: beaten to it!) i timed mine with a screwdriver and you really can get it spot on. the difficult bit is getting the cam belt on and tightened without it slipping half a tooth. make sure you double check your alignments once its all back together and tightend up.

I put the crank one tooth out so, that when I tighten the belt it puts the crank 'on time'. Obviously check it all after turning the engine over one complete turn.
