1953 Ultramatic Torque Converter, Remove the 2nd Turbine? Plus some mysteries

Posted by JeromeSolberg On 2020/11/28 1:25:10

Hi folks,

So after studying the manual and watching Ross' many helpful videos, especially this one:https://www.youtube.com/watch?v=-MMpGPeswaI

I checked the endplay before disassembly using the method here around 11:00 in another one of Ross' videos:https://www.youtube.com/watch?v=UNbjh_4eYF4

I found it be between 0.024 and 0.025, which is 0.010 too much (spec 0.010 to 0.015). So I will have to deal with that.

My biggest difficulty is that for the life of me I have not been able to separate the second turbine from the first turbine after removing the bolts. No amount of "tapping with a plastic hammer" in the manual seems to work. Any experience any of y'all want to share?

Apart from that, I have made progress in disassembling my converter. I have found it to be in reasonable shape so far, with a couple of mysteries.

1). When I took the turbine assembly out and exposed the clutch assembly, I found one of the clutch pressure plate spacers to be "hanging out" on the wrong side of the pressure plate, and in none-too-good shape. After removing the pressure plate I found two more spacers where they ought to be, but the 4th spacer either was forgotten or escaped as it's compadre had been attempting to do for some time.

2) I measured the piston rings as per the manual and found the large piston ring gap to be 0.019, which is out-of-spec compared to the manual's specified 0.004 to 0.013. So I will have to deal with that.

3) Does anyone know the code for the balance lugs? I think I have it right, but there is a chance I mixed up some of the balance lugs that were installed in 2 pieces at each location. I have the "thick ones" marked, but the thin ones which were underneath were not marked and I might have mixed them up. The locations were factory marked "A", "H", and "K", which I believe corresponds to the required thickness. As "A" was a single thin lug, I am o.k. there, but could have mixed up the thin lugs which were installed underneath the thick lugs in the "H" and "K" locations (see attached photo), which are fortunately very close to one another. Does anyone know what the codes correspond to?

4) The direct-drive clutch is pretty hard, I cannot dig my fingernail into it. So that needs to be relined.

5) Where according to the parts book I expect to find #3.618, ball-bearing assembly, I find instead a bronze thrust washer assembly with some vertical tabs (pictures enclosed). Maybe there is a service bullet I missed.

Thanks for your interest,

Jerome
