Damaged flywheel on 1929 "U"

[sunnen1250]

Is there anyone who has had a 29 flywheel repaired.  The ring gear is badly damaged and needs to be repaired.  Does anyone know where I might find a ring gear or have one made that could be installed on the flywheel.  There is no replaceable ring gear on the 29 flywheel.  The gear is cut in the perimeter of the flywheel and the flywheel would have to be machined to accept a later model ring gear.  Any help will be greatly appreciated.

I found this on ebay.   I don't think flywheels are interchangeable for all years though.  frank

Thanks, I think the one on ebay may just work.

Hi Neil,

I have not had to have this done but it appears that Frank might have found a replacement flywheel on eBay.  I would think that the original part could be ground and a new ring attached but it might be less expensive if you could find a suitable replacement part.  The 29 block was used for a number of years and I suspect that the flywheel didn't changed much.  According to the Plymouth Master Parts List 28-33 both the Q & U had ring gears.

Ring gear Q    Part# 319916
Ring gear U up to Y-201-PP US Built and All Canadian built   Part# 303039
Ring gear U after Y-204-PP engine #U-89290 All US built, 30U, PA  Part# 74455

I don't know why there were differences in the Ring Gear.  Form and fit might be different but I would suspect that function would be the same   Just my uninformed opinion. 

Have you talked to a good machine shop ?

Good luck Chet...

I believe you might find this article by Edwin Sapp on his starter problem very interesting in determining the proper starter ring for the 29-U

Please see attached:

Chet,  Interesting article.  I would disagree with Edwin's statement of both housings being for Bendix. The pictured #13 is described as Bendix and #14 as Motor Clutch.  The Motor Clutch uses the Shift Lever #17.  The starter must have changed with the change of the Ring Gear at engine # U89290.  The Delco-Remy starter motor for the earlier engine is 714-J as Edwin says.

All this hoo-ha said, do the flywheels/ring gears have the part number on them for identification?  How could you positively identify the e-bay flywheel?

Aren't these fun??

Frank,  THAT IS THE QUESTION ?  Neil might inquire to the seller what car or engine it came from.  Anything other than an early 29U might make it a #74455.  Ring gear U after Y-204-PP engine #U-89290 All US built, 30U, PA

Might also depend on which starter he has.  Who knows what these cars have in them after 80+ years of repairs.  Could be any combination now.  Maybe Ed Sapp can add some additional wisdom concerning the flywheel. 

Fun is an interesting description,  Chet...
