Ultima Rear Shaft - Is UT-18 and UM-614 the Same Thing?

Post by Snaab9-2 »

Will both fit the Pro XL? I see the 614 has a little hole in the shaft. Any other differences?

Also, anyone know if the pinion set screw is 3x3 or 4x4? The manual say different things in different places.

Thanks

UM 614 is listed as "REAR WHEEL SHAFTS FOR ULTIMA SC/DB" (RB-5/Rb-6 based), so maybe not. You can try, though.

Doesn't the Pro XL use the cone-drive hex washers? If the UM-614 has a hole in it, it must have pin-drive right? And therefore, they wouldn't be the same thing.
