Alpine Rear hub seals

During the full brake rebuild of my Series 2 Alpine, I also replaced the rear hub seals (the right hand side was leaking). After putting everything together the right hand hub is still leaking. I have read the postings regarding the fitting of a sleeve to the hub, but was wondering if a simpler solution would be fitting the bearing (with integral seal) from a Series V. Are they the same dimensions? Is there any reason why this wouldn't work?

Hi, just another thought. My new seals appeared to be leaking but it turned out I didn't have the hubs tightened on the shaft enough and oil was coming from the axle to hub connection. A 3' breaker bar did the trick.

3' breaker bar?

I don't remember seeing that in the SM....Page number?

I can hear the whining come time to take the hub off, next time.

180 ft/lbs is the recommended torque. Is there a danger of breaking the axle with too much torque?

I suspect that the threads (axle or nut) would fail long before the axle shaft would break. A stock S-V engine produces about 100 ft.-lbs. of torque. Multiply that by the low gear ratio of 3.12:1 and the final drive gear ratio of 4.22:1 and the axle shafts can potentially see over 1,300 ft.-lbs. of torque. There is probably a huge safety factor, so as a guess, the axle shafts might be good for several thousand ft.-lbs. of torque. In the real Series Alpine world, the Woodruff keys typically fail before the axle shafts (as proven by several dark-siders).
