Ok, I have the cloyes double roller. I am clearancing my timing cover using the grease technique. Does anyone know how much you need to grind away and from where? Everytime I put the cover back on I get new grease marks and I am grinding and grinding. I know it is not that thick so I don't want to accidentally go through it. The hard part im having is down by the crank seal. I am basically freehanding a circular grind around the bottom since the chain left an entire grease mark around that spot. I have not been test fitting the cover with a gasket on but the gaskets are not that think.

Does anyone have any pictures of where they clearanced their timing cover because right now it is looking like I will almost have to clearance an entire valley for the whole chain.

 

no pics but how are you checking it with the grease?

I clearanced mine without a gasket and then put it on. the gasket then added a little buffer zone.

You should apply grease or marking compound to the cover then bolt it on and turn it over. Then clearance where the grease or compound is gone.

You know what works well for this? Use some window marking chalk. Coat the inside of the cover where the chain and sprockets ride then chek to see what was rubbed off.

On my cover I had to do most of the clearancing in the cam sprocket/chain area not the crank.

 

^^ Ditto and it was a pretty small amount.

Use a very thin layer of something to check with. If you are using grease you don't really have to grind if the grease is touched by the chain, just if its wiping all the way off.

Once it fits the gap will be very tiny between the cover and chain.

 

Did mine on a mill. Will try and snap a couple of pic's for you
