Roll Pin on slip clutch

Sun Aug 20, 2006 6:41 pm

I have 2 slip clutches for the tractors, one is 1 1/8"? to 1 3/8"? spline, and the other is just 1 3/8-1 3/8" and i have lost both of the roll pins for them :oops: i was just wondering if you HAVE to have a ROLL pin in there? i know that they are hollow blah blah blah so they can get grease, but local hardware stores dont' have the right sized roll pins, they are too short, but are only bout 3/4 the length of the "correct" one... but would a shorter one work? apposed to using a regular pin the right length? (no hole in middle or anything)

just want some opions from people who know before i might ruin somthing....

Thanks for any help/advice

Johnny - Try a TSC store or Cub Cadet / lawn and garden equipment store. Roll pins are typically hardened and are there for a purpose.

i don't have a TSC place anywhere near me, and the cc dealer is a long ways away :cry: i know there is a reason for them, but would a pin work :?: or a shorter roll pin :?: i know that they hold it on the pto shaft too....

Thanks

Johnny,

What size roll pin do you need?

If the roll pin is longer than the shaft diameter and is centered it should work at least temporarily. I'd call Ken at Carter & Gruenewald and order some.

i don't nkow what size i need Don, i will check tomorrow, i think for now i wil just buy a shorter one, it's a bit longer than the shaft diameter, but not from one grease fittin to the other... i will call Ken in a few days, cause i NEED to cut like 20 acres in the next few days...

Thanks
