Engine bolt specs

[Tmac897]

Does anyone know the bolt specs for the rear oil seal cover? Checked with DBE and they didn’t have any info.

Also, need the specs for the pulley to crank bolt, if anyone has.

Engine has been apart for a long time and some pieces have gone missing.

Thanks,
Tony

Hi

The rear oil seal housing is held on by 5/16” UNC threaded bolts @ .750” long
The original crankshaft pulley bolt is a 7/16” UNF threaded bolt @ 1.125” long. You may find it difficult to find a replacement bolt at this length so the more common 1.250” long bolt can be used without risk of bottoming out in the hole.
