Looking for yokes & ujoints for Gravely PTO shafts

o2batsea · Nov 11, 2009

OK I know this is just a lawn tractor, but I know someone will have an answer. I have several PTO shafts for this old Gravely riding tractor. Some were clearly for a 400 and some are for an 8000 ( which is what I have). What I'm trying to do is make a 15T to 13T double u joint for the snowblower drive. I have the shaft that comes out of the front axle. This is 15 T. I have a couple of the Gravely 15T quick connect yokes and I will need to either bodge up or buy a proper 13 T female yoke to go on the snowblower side.
There are two kinds of ujoint. One takes a Neapco spider, the other is Rockwell. I can't find anything on the web about where to get these parts. Thanks.

OK found some part numbers. Small ujoints are Rockwell L6N and larger ones are Rockwell L12N. Cross reference is NEAPCO 1-1475, 1-1275; Spicer 5-430X 5-242X,
