Yesterday wheil getting the snow blower ready to mount on the 1855 I notices a loose snap ring behind the pulley on the PTO Shaft.

The snap ring is item # 26 in the diagram and the bearing # 27 had crept out about 1/8 of an inch. So being ingenious i pushed the bearing back in and put the snap ring back inside on the Nut #28. Before putting the snap ring back in i did feel the inside of the nut and did NOT feel any ridge or grooive that was to hold the snap ring in place.

After fitting up the snow blower I started the tractor engaged the electric cluth and then shut her down only to find the snap ring was back out of nut #28 and the bearing had crept back out like i had previously found it.

So here are the questions: Should there be a groove in nut 28 to hold the snap ring? And does nut 28 just unthread off of the sleeve? Anything unusual in removing the nut? Do I need to have the front end raised? I do have a parts tractor that has the pto shaft, nut and bearing still in it and the parts are there just wanting to know what to expect in fixing this hiccup.

Wish I could help, but I sold this complete shaft setup off my tractor as I didn't need it for my loader tractor.

The nut just turns off its threaded.The snap ring does keep the brg from comming out.But if I remeber right there is a snap ring on the splined shaft as well ,there's one on each end,I'am trying to think what mine looked like but I also belive that there was a snap ring inside the big nut also.Larry
