I've got a 283 chevy in my 81 chevy k10 pickup, and the harmonic balancer keeps coming loose. It doesn't use a bolt, so how do I get it to stay on?

I swear to god it has no threads for a bolt,,I acutally spent like 23 dollars on an ARP fastener only to find out there were no threads in the crank for a bolt...I found out that some sbc cranks don't use bolts, but I didn't find an answer for how they stay on...
Yes, it is a 283 in an 81 k10. It was an upgrade from the 4.1....It was stroked with a 327 crank...maybe that will help, maybe not

Hmm I think only the early 283/327s had a press-fit balancer. If its a late 60s 327 crank, check for a bolt hole. Check the balancer for a crack on the snout, or excessive wear. Check the crank snout for wear. I have used the red loctite in the past to hold the balancer on a 235 chevy, it was a press fit as well. Clean all oil and dirt off of crank snout and inside of balancer. Apply loctite to parts and tap it home with a dead blow hammer. Let it sit overnight. It'll hold as long as balancer is good and you dont over-revv the engine.

Not having a bolt is probably why it keeps falling off !!!
Actually, it may be held on with a large nut or maybe 3-4 smaller bolts. I suggest seating the balancer properly then use Loctite to hold the bolts in place. Oh yeah, torque the hell out of it !!!!

It Should have a bolt holding it to the crank.

Sounds like you need to pull it off and replace the little
press-tite spacer that keeps it on...
Perhaps a little lok-tite ?
Replace it with a 350 ??
