This weekend after a 40 minute stint on the track, we saw our transmission temps getting to 247F. That is on a day were it was about 45F ambient and we had the pump and cooler running.
Doing some research, the answers I've heard on safe temperatures are all over. The oil is good to 300F according to the manufacturer and some folks say they run there, but that seems really hot. Most folks say they like to be around 225F. We just rebuilt the transmission and set the R+P to the factory backlash setting of .007", but we're going to open the transmission up and loosen things up a bit. |

I am curious to know the tolerance spec of what I would call the front bearing/housing etc.
Not the intermediate plate...that can be replaced. The front one that is in the case and holds the pinion shaft. I wonder if there is a better solution there... A better and more modern bearing and potentially a machined sleeve for the case. Seems the flex is in that shaft versus the Ring/Diff setup which seems pretty stable, and can be beefed up with new plates etc. I am asking because I have never seen anyone address that point of the system... I have seen new side covers, better bearings. I have seen new intermediate plates etc. I have also seen ovaled out cases that are now considered junk. Not an easy solution, but seems a larger bearing seat to spread the load, and possibly a more modern bearing using more modern metal would tighen up that point. Seems like your failures are due to that pinion gear moving sideways. rich |
