TH350 NP205 Adapter Sleeve Coupler

Looking for some help on my 1972 K10, 350, TH350, NP205 Adapter. I want to get a new bearing and sleeve in the adapter but they seem hard to come by for older style. Can I use a newer style sleeve without the bearing and just have it float on seals? Trying to find another solution if unable to find original style bearing and sleeve.

Re: TH350 NP205 Adapter Sleeve Coupler

The replacement couplers eliminate the bearing in the adapter (no you don't need it in there). I replaced mine (TH350/NP205) and took the bearing out, put new seals in and has been fine for 5 years. Typically when the trans fluid leaks into the transfer case you need new seals. Here is a picture of my old adapter and the removed bearing. See the link below for a typical new adapter shaft without a land for the bearing.

That is good to hear, I was concerned the adapter bearing setup was required for alignment and sealing. Thanks
