Casing numbers on 1961 Cub.

Guys,

Got a centre casing on my Cub that’s past it’s sell buy date.

Im looking for a replacement, the replacement I’ve found has the same E4087 number as mine  , but mine is stamped underneath that as AM 1, the replacement is AM 2.

They look identical but that’s from a comparison of photos , not in person.

Will the casings be the same, I’m assuming the AM number is probably a casting batch and the part number is the E4087.

Thanks.

Sounds like these are just casting numbers and not matching case numbers. If line boring and other matching of cases has been carried out then I would expect to see after casting markings and not cast in markings. Complicated aint they these Cub devices!

Are they ever.

Give me a Sherpa engine any day of the week and I’ve not even started rebuild this Cub engine yet. Anticipating the air being rather blue when I start ?????????????

Might be blue after you’ve rebuilt and fire it up....oil smoke.

It’ll be interesting, just ordered a load of parts, the engine rebuild should begin Monday if the parts arrive.

Wheels frame and suspension are done, just that lump in the middle.
