ok, so long story short - the input shaft bearing needs replacing on my t176 (82 cj7) and ive decided to replace it myself. whilst ive never done anything like this before, all was going well until i went to a 'tranmission specialist' to remove the front bearing/shaft from the case. anyway, i left it with him (first mistake) and when i picked it up I noticed these burrs (pic) on the inside of the case, i.e inside the round hole the input shaft bearing is pressed into.
im so annoyed because this is the whole reason i wanted to do it myself, but because i dont know what im doing and ive never seen inside a tranny before, i dont know how bad this is. is it bad? clearly he has just gone to it with a screwdriver and hammer - christ! i could of done that!!! anyway its done so what now? is it just a matter of lightly sanding it down and it will be fine?
secondly, i know the input shaft bearing is the problem so i wasnt going to pull apart the main shaft and gears etc - but i noticed one of the synchros had a chipped/filed tooth. i was told however that this isnt a problem as synchros only need replacing when the rectangular cut outs on the inside are worn. is this correct, or should i just rebuild it? i do already have replacement parts.
thanks for your help folks, this site rocks and has been extremely helpful since i have been a cj owner.
