I am working on a center propellor shaft bearing assembly for my ton truck. Has anyone got any better ideas
just a thought but a TT truck is quite heavy with no additional power. I think you would be better off with a T chassis and an engine with performance parts. Perhaps you can find a speedster on the classifieds for cheap! Good luck with your T plane! Post pics when you get done please.
I've heard of folks drilling and tapping three holes around the circumference of the torque tube and running three bronze bolts up until they just barely touch the drive shaft and hold them in place with jam nuts. Mine does a little whipping around at 16-17 mph, but goes away as I accelerate through that point. Only lasts a second or two and it's past it. I don't give it much thought.
Joshua, A lot of TT trucks seem to have that vibration at a little over half throttle.
There have been some past posting on this subject.
A friend removed a TT shaft and spun it on a lath and found no problems on the shaft. His solution was the bearing Hal described. The worm drive seems to place some side torque on the shaft causing the vibration.
My family owned 1924 truck has this vibration. I just speed up or slow down a little and keep going.
After over 85 years it is still going so I am not going to get excited about fixing it.
My TT high speed rear axel,Ruckstell and Warford with lots of engine goodies it will manage 38 mph but due to prop shaft vibration it just ain't, Currently working on something special for it, I will keep you all up to speed. (no pun)
I think Gator in LA has a source for those. You may want to talk to him. Dan
Hahaha sorry for the joke Josh. I dont own a TT and was unaware this was a real problem! good luck!
Joshua, The bearing in the center of the drive shaft housing does work. We have two trucks equipped with this bearing besides the family TT without any modification.
You may have to get a machine shop to turn the shaft so the middle part is perfectly round. A shop that handles bearings should be able to help you with finding the right size bearing.
Thanks for that Will I am sure the truck will be a cracker when it is done I do have my own machine shop so that part is easy. I will post some photo's of it shortly, I also keep a RAJO Ford Special and have installed front brakes all based on 27 rear brake parts works well and looks right. Josh
