OK,guys Im the thrust take out GURU.
PSI X size of snout is=PSI against thrust
With that said Chris ,helped me repair mine after taking out two rotating assemblies.
I tried the orfice in the feed line to convertor and so did others TRASHED after about 50 passes.
What we did was bought Chris718s pump ,got tranny end play and crank end play to a minimum about .003.Shimmed convertor to I think it was about .060?
Also the main line pressure reduced from 210 to 140 psi with Chrises modified pump
I also do some modding to the thrust surface cutting a releif groove at a 45 on the parting half,oversizing feed hole to .250 ,and i cut a hole in the rear of the bearing half and chamfered it drilling into the oil galley with a 1/16" drill bit.
So far after two seasons good to go
Hope this helps
