i have a 1951 chevy 3100 with a 216 i am goin to install the balancer back on i have read up on heating it up in the oven before install so it will go in "smoother" i was just wondering what temp to set the oven and how long to leave the balancer in there for? because i dont want to damage any rubber componants by over heating it, i just installed a new front cover seal and dont want it to melt before it takes its first spin.
