D18 TCase rear output seal?

[Buildflycrash]

I remember someone mentioned a "Double Seal" for the rear output. Can anyone provide a part # or link?
Thanks for your input.

I think there is also a version marketed by National. You need to either use a sharp utility knife and reduce the felt "seal" to half thickness or just leave it out.

Same p/n as F-M, also Timken as well. I actually put two of these in Tonk & still had room for a thin felt.

Shop brands carefully, I cannot remember exactly which ones but some brands do not use a spring wrap seal which is generally preferred. Also seal overall thickness can vairy from brand to brand, I found some were too thick to allow two of them to be used. Installed double seals and felt on both the front and rear output shafts on my D- 20 and on my d-18.

Hmmm, I just used a SKF 15450 seal when I changed the yoke on the output shaft on the D18 to eliminate the 4 bolt flange yoke. It does seal things, but seems I might have used the wrong seal?

Your results? I have not had the double seal installation leak.

I have not had a leak on either the front or rear out put since installing the double seals on the D-20. I have probably 3-4K miles so far. The results are still undecided on the D-18, as I only drive it occasionally, maybe 500 miles on it in 4 years. But so far no leaks. I cannot remember for sure but I am thinking I used National seals and packed plenty of grease in between the seals because the outer seal won’t be getting any gear lube.

Same here on my 18.

I did as well.

I used wheel bearing grease on that outer seal.

I used wheel bearing grease on that outer seal.

I think I did too, and maybe assembly lube on the other one. Either one appears to work ok.
