    So I have disassembled my T-14 tranny. When removing the roller bearings and spacer washers from the counter shaft, I removed 4 set of spacer washers, each was doubled up so I had 8 in total. here is my dilemma.

    per Novak instructions and my TSM it shows the use of 4 spacer washers in total. I checked the thickness and one washer from my rebuild kit and one of the original washers are the same thickness. Has anybody else ran into this? If so did you use 8 when you rebuilt or did you use 4?

    Are you talking about the 4 washers/spacers in the photo just above the needle bearings that go inside the counter shaft bore at each end of the needle bearings?

    IIRC, what is critical is not just the thickness of the 4 spacers, but alos the length of the needle bearings. I'd compare the length of the needle bearings that you took out with the ones in the Novak kit. I can also probably find the ones in this picture that I took out and get measurement if needed.

    Correct. Those 4 washers. I didn’t think about comparing the length of the bearings. I just compared an old to a new and they appear to be the same size. Definitely not enough difference to justify a second washer.

    If I remember correctly, one you put all the needle bearings with the 2 spacers on each side, the outer spacer should essentially be flush with the end of the countershaft, and then there are the thrust washers on that go between the countershaft and the side of the case. I would test fit a bit...if you use just the 4 washers (1 on the inside and outside of the needle bearings on each side), everything should be flush...If all 8 were used previously, I would worry the thrust washers either suffered damaged or something is/was wrong with them. I'd also compare thickness of the new vs old thrust washers....There is not much excess room to fit 4 extra spacers - maybe the inside of the case were the thrust washers ride is messed up?

    That is probably what I will do. I am going to post a picture of the case could you confirm that everything looks normal. This is my first time into a transmission.

    I can’t get a picture that shows much. Once I get the outer washers to sit flush, and install the thrust washers the shaft should be installed with very little to no play front to back?

    The outer washer/spacer should sit flush with the end of the counter gear, and it should not be able to be 'pushed' further in. IIRC, spacer goes in one end, then the needle bearings go in, and the the 2nd washer/spacer on the outside. When that washer/spacer is pushed in, it will push the inner spacer to the stop inside the bore, and push all the needle bearing up against that inner spacer, leaving just the right amount of room for the outer spacer to slide in flush with the end of the bore - I guess if you could have too deep of a bore inside the shaft before it hits the stop, so an extra couple spacers were used? Once the thrust washers are installed, there should not be any significant play (like the thickness of one of those spacers), although I would guess there is a proper spec somewhere around few or 10 thousandths? Lets say, it probably should not be bound up tight.

    Thank you for your help. I will post an update once I get it cleaned up and start rebuilding.

    I have the transmission reassembled. Ended up have to use 8 spacer washers to get the outer washers flush. I have one more question for you. If I grab the output shaft, I have about 1/8” of endplay. Does the transfer case seat to the rear bearing adapter to tighten things up? Or do I need make sure I didn’t miss anything.

    I believe once I get the transfer case installed onto it, it will go away. It looks like the play is coming from where the drive gear shaft slides into the main shaft. Everything works flawless if I keep a finger on the read adapter plate.
