PhanDad 3,251 Posted June 25, 2010 there were two difference sizes: I was doing some parts house keeping and came across a few of the drive shaft disks. I was surprised to find the old (I presume) drive shaft disk was larger in diameter than newer disks. I don't remember what tractor the bigger one was installed in, but obviously it ran with loose bolts for while - but didn't fail. Pretty tough stuff. Share this post Link to post Share on other sites
wilm169 1 Posted June 25, 2010 The larger one is off the powermax PTO. Share this post Link to post Share on other sites
larry8200 4 Posted June 25, 2010 Almost looks like the hole patterm is the same, just one has more material on the outsude. Did you check that? Share this post Link to post Share on other sites
PhanDad 3,251 Posted June 25, 2010 Levi, I've never had a Powermax, so it didn't come directly from one. However a PO could have used a Powermax disk in their tractor before I got it. Larry, Yes, the bolt pattern is exactly the same. Share this post Link to post Share on other sites
HubbardRA 19 Posted June 25, 2010 There are two sizes of the disks for the large frame tractors. I have a couple extra on the shelf and there are two different diameters, but the hole pattern is the same. Share this post Link to post Share on other sites
SmilinSam 3,623 Posted June 25, 2010 I know that the 1967 2010 and 2012 I used for my project originally had the larger ones on them. Cant remmeber offhand when or what models the smaller ones showed up. Share this post Link to post Share on other sites
TimJr 206 Posted June 25, 2010 I'm pretty sure that the manual steer Sunstar/Ultima tractors used one on the steering column too. I don't know if it was the same as the driveshaft ones for the other tractors or not. Tim Share this post Link to post Share on other sites
