Nothing better than a nap on the creeper under the old truck.

Re: Rear main seal
Since Cabovers have been out of the US market for close to 20 years, finding new shifter parts was a challenge. None of the new Eaton transmission parts books cover the old remote shifters. A day of digging found both an Eaton part number and an IHC part number. Eaton part number went no where, had to wait till Monday to get Check the IHC part number, which had been superseded, and got the new number as well as a new Eaton number.
With computers making things like cross-reference quick, one would think that when I entered the old part number into Eaton's website, I should have been directed to the current number, but no!
New part is ordered, so hope it will get here soon.
Cold to be pulling transmission out side. My air tool freeze and my fingers get fumbally.

It is a funny thing how you never notice how loose things are getting until you replace with new tight parts. The shift is much "crisper" and rivals a conventional truck with the shift rod straight into the trans.
I also went thru are re-sealed the fuel pump. Whoever built the pump really made a "pigs breakfast" of the job, and I doubt it ever worked as it should.
It was my 1st time getting as deep into a Cummins AFC pump, but I had some "guidance" from some old hands on another site. Starts easier with less smoke and seams to have more power. NO leaks! More ever I was able to correct the problems/mistakes of the previous builder. I have 5 Cummins PT pumps (well actually 6) The one I was in was the latest generation with the "shaped port" AFC and was a bit different than I was used to. I have 4 other 1st gen AFC and one PTG that I keep around for parts only. I feel a lot more confident working on them now.
