I made a bunch of gaskets (joints) of various thickness material for the main bearing housings, and by trial and error added or removed them untill I had just got rid of end play in the crank. Some are made of plain typing paper. I have read of others using a few thousandths of end play in the crank for TRBs but I think they should be just snug like the wheel bearing on a car.
This was a great reply from "12 gauge" on page 1 of this thread, that answered the question well.
All tigger needed was to shim it up with paper shims as documented very well by Quinn in his excellent kit engine report on the Utterpower website.
It is unfortunate that it went down hill from there.
Tigger, if you are still there, I wish you all the best for your venture. I do not consider what you are doing to be out of the ordinary or risky if done carefully.
As Nobby demonstrated on the previous reply, it is a valid and commercially available option to chance over to TRBs.
Yes tigger got a little upset because of the comments of some, and lashed out a little to others who may not have deserved it, but this is what happens when a guy is dealt with unreasonably.
Tigger, I hope you will still hang around this forum. It is usually not like this. We are normally very friendly and helpfull.
All the best to you Tigger!!!
regards,
Matt
