    Stephen, I just recieved the th400-np205 input gear and bearing. It arrived in good condition, Thanks!! As far as boring the case, the bearing should be a light press fit, correct? Am I correct in thinking it should be no more than .0005 bigger than the bearing? I lean toward making it a slight interferance fit to keep the bearing from spinning. Your thoughts?? Thanks again for the parts!

    You're pretty much right on, we usually find it to be a tight slip fit. Lots of wordy definitions for this stuff. Generally what we recommend is to measure the existing bearing and hole and use the same fit. 5/10ths over should be fine.

    Hey Ramjet, I'm on the east coast- I could do the job for you and probably save you some shipping costs as well.

    Local is typically cheaper because of shipping the 45 lb bare case around. We can do it here, charge for an exchange case is $90 and you'll get the case quick, if we bore yours we have to work it in and it's about $60.00.
