Ford Vibration Damper Questions February 12, 2017 01:22AM
What's out there as far as a damper for a small nose 6 bolt Genesis crank (same nose dia. as 401)? I'm still using the 8000 cast front bolster, so O.D. is limited. Max. rpm will be in the 3.5-4k range.

On a 7.8 with a 401 front cover - Has anyone found a front crank seal that fits the 401 front cover & 7.8 stock crank/damper without machine work? I haven't taken the time to search seal catalogs yet, but would think it exists.

Thanks!!

I went to a specialist machine shop and they bored my front damper to fit the 7.8 nose and I had them make me a custom sleeve for the 401 front cover and seal. Had the whole front converted to a 401. As far as the 456 with the 6 bolt crank my stock balancer and 401 seal sleeve fit right on. I just had to have the crank gear changed to a 401 gear

Thanks for the replies! I should have been more specific about the Genesis setup. I already have what 7040 stated, but my old balancer is done now. So I'm looking for options to replace it.
Used - Spend $ on 50 year old rubber that might do same thing??
Reman - Company I found no longer doing larger than auto size dampers.
New - $$ is so much that's why I'm asking if any aftermarket or high performance is available. If I'm going to spend what CNH wants, I should be able to upgrade.

On another note, while I have blue folks looking:
Does anybody have .020 over pistons for sale for the 7.8?
Best head gasket options for genny head to 7.8 block?
Thanks!!
