Hello and thank you for using JustAnswer.com
These older balancers can be a bit of a pain
There are two threaded holes in the balancer. I normally tap them to clean them so I can use the M6x1 bolts to thread in them and use the puller
See image as a example
The bolts need to thread in pretty good to grab. You can't use a couple threads. It will pull right out
There are 5 holes in the balancer. Does not have the hollow slots. Photo must be of a newer balancer after 95?
That is really not a picture of the balancer on your truck.
That is just to give you the basic idea
It's a example picture
I'm way beyond what the puller is. As the balancer is siezed on the crank, you do not know of a 2 piece replacement lower timing cover is available? or if I can use the 5 threaded holes in the balancer to jack against the timing pulley without damaging it?
