Carrier bearing issues

[socaldatsun]

So I'm swapping a ka24e into my 72 pick up and I wanted to use the 240sx drive shaft since "we'll I think" it's stronger and will hold up to a little more beating. I am going to have the drive shaft cut and lengthen but I was woundering what will have to be done about the carrier bearing? Can it be relocated by a few inches do fit the stock xmember?

Anything can be done. Sure.

 

Easier to shorten the front of the stock 620 shaft though. You may have to shorten/lengthen both front and rear shafts on the S13 driveshafts to get the carrier bearing in position..

For that amount of trouble I would just get a one piece shaft built.

Well I still have both the 521 shaft and the 240. The 240 is way thicker then the 521 so commons sence to use that one. I've read a lot of threads about ka 620 builds but never come along to what they did for a drive shaft. This would be my last part to have "everything" to have it running if everything works out: wiring, and radiator clearance.

Because a 521 drive shaft is two short sections, It does not need to be as large of a diameter as the 240-Z drive shaft. Another issue s the 521 drive shaft turns at a higher RPM than the 240-Z, because the 521 rear axle ratio is lower, (higher numerically)

I would leave the carrier bearing where it is. Shorten the front half of the 521 drive shaft, and put a yoke on the front end of the that shaft to match the transmission on the KA24-E.

I used these guys to do shorten the front half of a 521 drive shaft when I put a Z-car five speed in my 521.

I am sure you can a drive line shop in the LAX area.

It's a240sx shaft and I was just worried about it snapping or something due to the added power.

I just used my stock 620 shaft in my swap. I would have had to shorten it to fit the stock 240sx transmission, so I used a 720 transmission that was the same length as the stock 620 transmission.

What part of the drive shat do I need? I have a guy asking me for the yolk and the flange that goes to the yolk? I have the 240sx yolk that fits my tranny

Why not do a 1 piece drive shaft and get rid of the carrier bearing.

[socaldatsun]

Cause I'm not filled up with mula like you mr. big :)

[kelowg]

it well cost close to the same to have one lengthened/ shortened as it does to have the one piece made. given u have yokes from the old one(s). this is what i did, best thing i ever did to her. makes clutch r/r's much less time consuming.

You can't use the 240sx drive shaft AND the carrier bearing.  So, either you use the 521 driveshaft (and have the front half shortened and altered for the transmission) or have the 240 shaft altered to fit, eliminating the carrier bearing.
