cam sprocket alignment and cam end float
Turbo Mini Forums

just wanna run this by you guys on here, currently building an engine spent a bit of money on it so wanna make sure I'm doing things proper. I'm currently fitting the cam sprockets and noticed the crank sprocket sat too high so i removed 1 shim and appears to align correctly but iv never heard of removing shims only adding them lol is what iv don acceptable or is there some wrong elsewhere?

is this the best way to check? or should i be measuring at a different angle
secondly my cam endfoat is 0.04

is this ok?
do you guys use cam chain tensioners with duplex timing chain?
matt

that all looks ok,

personally ive never bothered to alighn the pulleys, thats nt to say its not worth doing though.

I always use a tensioner,

the endfloat seems fine, you should be able to get that DTI more in line with the cam though to get a better reading, being on the piss like that will give a different reading although probably only about 1/4 a thou

ok cheers, yeah i know the dti should be more up right i realised when i posted the photo lol i'll check it again tomorrow just to be sure. i think i better order a tensioner before i do the cam timing

The tensioner is down to personal preference, I dont use one and neither do any of the big engine builder names but a few on here do

I seriously doubt it!

I concure with paul

It Has been mentioned in previous. Threads, the single row tensioner on a duplex chain stresses the chain link pins, premetureley wearing the chain out thuss affecting the cam timing from optimum. ... sadley they don't make a duplex tensioner

I don't use them for this reason and never have.

I keep forgetting that the rest of the planet went metric last century. I was going to say that forty thousandths of an inch is too much slack if you run a distributor. But if you measured 0.04mm (can't read the dial in your pic) then I think that is too tight. Recently I measured an older A series stock cam setup, and IIRC it was .008".
