datsunan Posted October 11, 2004 Share Posted October 11, 2004 I just installed a BW t-5 in my 240zt, I have already busted my new u-joints on the stock DS so I went to a driveshaft specialist to have a heavy duty one made. I brought him my input yoke off the 73 DS and Another input shaft from a z31 that has the bigger u-joints on it but that but niether yoke will fit in the BW. He tells me that the yoke I need only came on the automatics and it is to thin of a wall to use with this much power. The yoke from the 240 is to small and had the wrong # of teeth and the z 31 has the right # of teeth but the wall thickness won't allow it to slide into the tailshaft. Whats the deal? I know lots have done this swap but I can't find anything in the seach with anyone having this problem. Can I change out the tailshaft so I can use the thicker walled 26 count input yoke? Please help. Thanks Paul Quote Link to comment Share on other sites More sharing options...
Cody 82 ZXT Posted October 12, 2004 Share Posted October 12, 2004 Sorry I don't have your answer but, it seems like changing the tail shaft out might be the best option. Quote Link to comment Share on other sites More sharing options...
datsunan Posted October 12, 2004 Author Share Posted October 12, 2004 Yeh I looked at the five speed I have now and the case is totaly different, where the shifter goes in is like a box compared to the round style of the NA 5 spd so that won't work. Does anyone know how hard it would be to take the output shaft out of the BW t5 and have it cut down a 24 spline? Can I swap out the spline with another?

Trevor Posted October 13, 2004 Share Posted October 13, 2004 If the Z31 yoke allows larger U-joints, Could you (machinist with a lathe) turn down the outside of the Z31 yoke until it fits in the tailshaft of the T-5? Quote Link to comment Share on other sites More sharing options...
datsunan Posted October 13, 2004 Author Share Posted October 13, 2004 Yeh thats what I'm doing now but it will cost me $130 because it needs to be center ground perfectly and then the wall will be thin making it weaker. I guess I don't have a choice. thanks for the reply thou. Quote Link to comment Share on other sites More sharing options...
Cody 82 ZXT Posted October 13, 2004 Share Posted October 13, 2004 What about machining the tailhousing? Quote Link to comment Share on other sites More sharing options...
datsunan Posted October 13, 2004 Author Share Posted October 13, 2004 Hey Cody, thats a good idea. I could machine the tail housing and then use the seal and bushings for a Z31. I just picked up my machined yoke and dropped everything off at the DS shop but if it snaps the yoke I will be trying it your way. thanks Paul.
