Pinned balancer removal So I’m gonna do a cam change , ditch mast vvt cam and go with a btr blower cam . I double pinned my truck balancer when I put the whipple 2.9 on . So now what ? remove and put same one back on ? I could buy a new one, and pin in a new spot? Im Still on a 6 rib belt but it seems to be fine with the gates rpm @14 lbs . Also what do I need to get rid of vvt? New timing set , timing cover , was thinking new oil pump high pressure/ volume . Anything I’m missing ?

Take your balancer to a machine shop with a knee mill or CNC, and they can get the half circle you need with an end mill.
I'm guessing .25" diameter pins?
If the pins were put 180 deg apart from each other and there is no reason to index the HB then, a machine shop can do it very easily no problem
If the pins were not 180 deg apart from each other then you may have to get creative or pay someone to get creative.
Edit: Make sure it is chucked up on the interior portion of the HB. If they clamp it from the outer rim of the HB, the tooling pressure combined with the rubber on the HB will make for an inaccurate machining operation. A machine shop that knows about engines will know this, a regular machine shop may not
Edit 2: I guess you could also reuse your old HB. May need to get creative in reinstalling it

Ive removed my pinned balancer and reinstalled double pinned without issues. I just used a new spot on both the balancer and crank. I like to use a brand new bit though.
