Transmission

I have been working steadily on rebuilding my
Farmall m transmission I have got all the bearings
from the front of the transmission to the bull pinion
replaced now I am left with the axle bearings. I want
to replace the inner axle bearings with the roller
style used on the 560's as I mentioned last year and
y'all were really helpful giving me information. I
know that 375215R91 was the original part number
but is no longer available through Case, then the
new part number that was gave to me was
529427R91 and I found the part on Case's website
put it in the cart and got busy doing some other
things but now have devoted my time back to
restoring this ol' girl, but now after looking closely
529427R91 is listed as 65mm ID X 120mm OD
which would be for a 2.5" axle so this bearing would
not work I'm assuming? I have tried browsing the
internet trying to find a match but still am having no
luck I need the 70mm ID X 120mm OD bearing that
was 375215R91. Any help is appreciated! I will
include some pictures of the rebuild I even went to
the extent of replacing the bushings in the reverse
idler gear.

The number thats scribed/stamped in the outer race is your best possibility of crossing it over to something newer. I have seen them on the rubber seal on newer bearings also.
 
Thank you, the pictures are out of order but I will probably do a write up once I am finally done so I can help out anyone who is wanting to tear it down like I did. I think I will go to a bearing distributor there's one not far from me, Is there a certain number I should be looking for stamped in the new roller I get? I know that most of the ball bearings were deep grove or maxi-fill so that got me a little confused on which roller would be best.
 
Three piece bower bearing had number 1214 on all three pieces. Would need to lookup letter or letters that went with the numbers if needed. Think it was 1213 on the tractors using 300 size bearings. Think the bearings were made special for IH and not sure if anyone is offering them now.
