this is going to be my first roller cam i have installed and want to make sure i do it right. i was told i need a thrust button and retainer plate and a wear plate is that right? also how do i know exactly what i need and how to shim it? how do i know what thickness wear plate to get? i have purchased the comp cams xr294hr-10. this is also a retro fit i am doing.

 

The eaisest way I know to do it, is to knock out your back cam plug and
set up the dial indicator to read on the back side of the cam. You want
around .010. you will need a stiff timing cover as well, beacuse a stock
one will often flex while trying to set endplay and your readings will be all
over the place.

 

what do you do if the motor is still in the car?

 

A two peice timing cover would be the easiest.......

I guess you could do the 'ol tootsie roll trick, like when you check piston

to valve clearance. Take all the washers off of the cam button and install

it. then take a tootsie roll and smash it a little bit then use some scotch

tape to attach it to inside of timing cover where it will contact cam

button upon installation. put gasket on timing cover and then push timing

cover down on to dowels and as far as it will go onto block. Remove

cover, carefully take tootsie roll off of inside of cover, then put tootsie roll

in your freezer for 30min or so to make it hard. after 30 min or so, you

measure your squished tootsie roll with a set of dial calipers and it should

give you the dead nuts measurement.

your timing cover gasket should be roughly .010 or so thick, so if you can

get your timing cover to barely contact cam button without gasket on,

you should be in the ballpark.

 

that info helps alot i didnt think of that. i like that cover too but its a little expensive but i might just have to spend we'll see. thanx

 

Im sure that there are other methods out there for in-car roller cam button setup, but those two are all I could think of. Good luck!
