You can get a modified retainer with the seal installed and ready to bolt on to your engine for about $50 from tst. It's worth that to me to not have to do the job over again.

Quoting Steiner tractor parts for rear crank oil seal.
"International / Farmall - Fits: [ Cub, Cub Loboy, U1, 154, 184, 185 (For all models using later retainer: must be used with late # 251363R2 rear seal retainer, will NOT fit tight in early # 251363R1 retainer. For engines with the early R1 retainer, you must either change to the late R2 retainer or use loctite 660 or something similar to retain seal into the R1 retainer. (Early R1 retainer has bore size of 3.881", late R2 retainer has a bore size of 3.876", seal has an OD of 3.881")) ], [ Baler: 50T, 55T (For all models using later retainer: must be used with late # 251363R2 rear seal retainer, will NOT fit tight in early # 251363R1 retainer. For engines with the early R1 retainer, you must either change to the late R2 retainer or use loctite 660 or something similar to retain seal into the R1 retainer. (Early R1 retainer has bore size of 3.881", late R2 retainer has a bore size of 3.876", seal has an OD of 3.881")) ]; Replaces: 251378R92, 360662R91, 364692R91, 364861R91"unquote.

My R2 retainer measures the same specs as quoted above.
i understand using the R1,I don't understand why my R2 needs to be modified.

I think if you get the correct IH seal, you won't need to modify the retainer. The R2's are few and far between and was probably installed when the engine was redone by the PO. TM also has the R2 retainer and seal.

Don't put a lot of faith in technical information from Steiner's catalog. You can read the straight information on R1 vs. R2 in this thread. All you need is a seal that has a proper tight fit in whatever retainer you use. There are several ways to get there.

I was basing my comment on the retainer and seal available from TM. I had forgotten about the post that Jim referred to.

:Dito:

aggred. they have messed me up several times before farmallcum.com

if the po did a rebuild replacing the seal and it is not leaking what is your concern?
When you only have 9 horsepower you need to know the names of all of the ponies!

I don't know when the overhaul was done,so as
long as the engine is out I'll be replacing the seal and
all the other seals and gaskets whether they need replacing or not.
I call it peace of mind down the road.
