Sorry if this has been discussed before but I tried the search and found nothing to help.

My 2wd Sapph is running Kent BD10s and vernier pulleys, I am changing the timing belt tomorrow (friday) and I want to know if theres a certain way to set them? I dont trust the way they are set at current because inlet is at 0 degrees and exhaust is right round to the end of the adjustment. I cant see any visable timing marks on the pulleys like the arrows on the standard ones so how can I tell if they are set ok?

Also I have heard that if you advance one cam 10 degrees and retard the other 10 degrees this is the best way to run BD10s? Is this true, if so which one for which?

Do the verniers really make that much of a difference with BD10s as they are only a mild cam?
Was thinking of just putting standard pulleys back on it.

Any advice/experiences/info would big a big help

Thanks in advance, Ian

 

The pulleys are only really noticable on big cams when adjusted for power gains.

The main reason for Verniers is to get the cam timng bang on, after all most cosworth heads have had a good few skims so with a head that has been skimmed say 3 times, the belt is not going to line up exactly so the verniers allow to be "dialed in" to put the belt Spot On as without them on a head that has been skimmed loads, std pulleys can make the belt be out over a tooth which isnt good.

 

So do how do I set it on the verniers then?? Im fairly mechanically minded I just havent done this with these pulleys before.

BigErn are you sure they are kent cams in there not just kent pulleys, you need to take the rocker cover off and see for some part numbers on the cam shafts and then reference them back to the manufacturer's spec and time to suit cheeRS paul, if you find the info out and want a number of a clever bastad to tell you how to time them up then drop me a txt and i'll give you his number.
