About differentials inside of riding mower transaxles,,, how do the axle shafts attach to them?

 

[TUDOR]

Usually a spring clip, 'C'-clip or a pin near the inboard end of the axle.

Usually the end of the axle shaft that goes into the differential has splines and it slides into a matching splined hole and is held by a clip like Bob said.

What size axle and how many splines are typical?

 

[TUDOR]

That depends entirely on axle capabilities, who made it and when. Light weight RERs may have a 1/2" axle with one spline (keyslot) and a heavy GT may have a 1 1/8" axle with many splines. Plus there are at least a couple of spline configurations for each size of axle. Axle diameters go up in increments of 1/8" as a rule.

For instance, Chevys came with 2 different splines on the same size transmission tailshafts back in the 60s, and I think on the axles as well.

There is no easy answer without specific information.

I found a Cub Cadet 682 differential with fine splines but the owner doesn't can't read how many splines it has with his eyes. Does anyone know the number of splines and the shaft size?
