[STAG1973]

Are there any timing marks on the block for the jack shaft and crank, if so where are they....:?:?

The timing mark for the crank is the one on the front pulley. Be aware though that it is often several degrees out from true top dead centre. There is a line on the jackshaft sprocket that is supposed to be used to time it to the crank. I forgot to bother when I built my last engine, but it makes little difference except that you may have to remove the distributor and turn it to the next tooth to get the rotor arm to line up with the appropriate plug lead. The important thing is to get the cams timed in properly to the crank.

It may be me but the jack shaft sproket don`t seem to line up with anything even though there are lines on the wheel, :?:?

I haven't done this job for 30+ years so can't help personally however if you look on the LDparts site at: http://www.ldpart.co.uk/shop/shop.ph...&image.y=8

he says, about the jackshaft sprocket, "Correctly made with 1/4 dowel holes and timing marks correctly aligned to tooth point and not valley" which, I think,infers thatthere are some out there which are marked differently from the original :?

I hope this may be of some help - Good luck

Cheers Julian,

The timing on the stag engine seems a bit vague to me as there are no positive marks on the engine, i may be looking at this too deep. I will get there

Adrian ,tempereraly put your timing cover back on and your front pulley ,set the crank to the tdc using the notch in the pulley against the timing marks bolted to the timing cover then remove the pulley and cover andget the cam markslined up with the marks on the no 1 cap marks .thats the important bit ,like Neil has said the jack shaft only does water pump and distributor which you can rotate in to the correct sector before you drop it down and adjust.
I take it the cams arn't bolted down whilst your turning the crank otherwise things could be hitting each other.


Good luck Steve

Cheers Steve i have preset the timing on thecrank and the cams before bolting together, i have found the best info on this is the Practical classics book on the stag rastoration page 58 - 59, and aswell as all the help from everyone here.
