O.K. T5 or any manual transmission specialists I have a question for you guys. I have a 1961 348 that is being mated with a W/C T5-S10 transmission. I traded for this car 32 Ford 3 window and both the engine and transmission have been rebuilt. I decided to pull the transmission off to make sure everything was torqued and to make sure all of the clutch mechanism were o.k. I noticed that there was no pilot shaft bushing in place in the crank shaft. I purchased a bushing for a 1961 348 and that is where the fun began. The bushings OD was too large for the end of the crank (fit perfect on the transmission). No problem I researched and tried to find a bushing with smaller OD, no success. I took the bushing to the machine shop and had them turn it down to the OD of the crank hole (used an electronic dial caliper for the measurement). Brought the bushing home and it installed fairly easily ( I did have to use a brass dowel/punch and made sure not to damage the busing). Apparently I did not have the bushing turned down enough as the input hole has now shrunk down and does not accept the transmissions input shaft. NOW TO MY QUESTION, HOW PERFECT DOES THE ID NEED TO BE IN RELATION TO MY TRANSMISSIONS INPUT SHAFT?[/B] I have taken my dremel tool with a 120 sandpaper drum and "reamed" out the ID and the transmission slid right in. I am only testing at this time and can easily buy a new bushing and take back to machine shop. Currently the transmission fits nicely but the fit is not as "snug" as it was when the bushing was new. HOW MUCH PLAY CAN THERE BE IN THE PILOT BUSHING VS TRANSMISSION PILOT SHAFT? DO I GO FOR IT OR HAVE THE BUSHING RE-MACHINED? By the way I know the right answer (re-machine) but I am getting lazy and frustrated. I have heard of guys in the old days running with no pilot bushing with manual transmissions.
