Sloppy timing chain. UPDATE

Ken Betts Racing has the + sizes for BB Buick, I'll ask him tomorrow if he has any + sizes for the 350.

 

I called TA yesterday and they don't know how to measure it either. I am affraid that when the chain is too tight and eating my crank and cam bearings alive...

 

Not too tight, Needs to be just right. Never going to get tighter with use.

 

Just put the cover back on and forget you saw the chain, it will be fine

 

I ordered the 0.003 today. We will see. To try is not a option overseas.

 

.003 will be better. You might even have gotten away with a .005
Looked pretty loose in vid.

 

With the shorter chain I would definitely degree the cam, don’t forget it’s going to be shorter on the tight side too, so that will pull the cam clockwise a tad, if I’m thinking correctly

 

Mark, it's not shorter chain, it's same.
Gears are made slightly oversize to take up the slack.

 

I put mine in the freezer to shrink it

 

Now you gotta drive it fast before it warms up and stretches again

 

Not that I know of.

 

Put in the new 0.002 oversised dubble roller timing chain from TA. And slack is gone.
Happy....

 

Excellent!

There you go!

 

I hate to say this, but I know it will save you from having to do this all over again real soon.

what I mean is it does not look like you pre- lubed the chain up anywhere, and I mean anywhere to the point it needs to be!

it should be dunked in a can or bowl of oil and then each roller should be spun around to spread the oil thru the roller.

it may sound like I have COD, but the chain will live a normal life expectancy from taking 10 minutes to do it this way.

squirting the chain with a oil can as I have seen too many folks do will not get the job done the right way and you will be chewing up the new chain from right at the moment when you first start the motor!

 

^^^, Yep, looks like the 150 dollar 9 keyway billet gearset. Take it off & lube it up. Nice gearset!

 

Best tip of the day above ^^^
