Balancer bolt torque spec

[turbodaniel]

If the crank balancer bolt is torqued according to spec which is approximate 240 lbs.
How can this happen

It can't and shouldn't if the clamp load is correct.

Assuming If the clamp load was correct... Is there any possibility of it loosening at all?

Cracked balancer?

If it's 5/8 thread it has 24000lbs of clamp load. I don't see that coming loose without something acting on it.

The stock balancer is not a friction fit so that's why it needs to be 240 pounds of torque because if not it comes loose the balancer I will come right off

ARP has a bolt for our cars check it out . Less of a hassle torque wise.

Something dimensionally incorrect with the lower chain sprocket?

Is it possible the bottom timing gear was on backwards? From the looks of the missing piece of key, the timing gear didn't have much bite.

The keyway isn't designed to provide any structural support although it only extended into timing gear about 3/16. I will post pic of timing gear

I had a timing sprocket last year that needed shimming but I don't think it would be so bad that the bolt would load up on the crank snout before clamping the balancer and the sprocket? Something to check for anyways

 

[BEATAV8]

It was a progear set btw

 

[turbodaniel]

seems there is only about a 1/8 of contact surface area

 

[TurboBuRick]

That bottom gear IS backwards. Shoulder side of the gear is suppose to be facing out.

Were you running an oil slinger? I've seen instances where if the oil slinger is left out the stack up of the lower timing gear and balancer and is shorter than the length of the crank snout. You can torque the bolt without clamping down the detail parts because the washer bottoms out on the FWD end of the crank.

Yes everything was there and installed correctly... the timing gear flopped out before I took the pic... I wanted to show the wear area
