Re: '63 K NV4500 removal / reverse build thread

Heres the countershaft. Nothing special here except that it is a MASSIVE part that weighs close to 30lbs. I just thought it was interesting. After I reinstalled it, I was able to roll the MS back into the case, install the 4th gear syncro, the input shaft and bearing retainer. I used indicator to check countershaft endplay (.004) and MS endplay (.003). The manual calls for .002-.006 on both with the lesser being desired on the MS.
