    Rockshaft snap rings failed

    I was recently mowing with my rotary cutter and noticed a clanking sound. I stopped the machine and noticed that one of the snap rings was missing on the rockshaft that controls the lift arms on the 3PH. The missing snap ring allowed slack from side to side that was causing the clanking sound. An O-Ring also had come out of place because of the slack. I pushed the O-ring back in place and installed a new snap ring. There seems to still be a small amount of slack but i think that is normal. My question is could this have affected anything else internally? it seems to work fine. What is the purpose of the O-ring? I could never figure out what actually engages the Rockshaft that makes it rotate and lift.

    thanks

    The rockshaft snap ring groove on my 1026R is about 1/8" from the end of the rockshaft, judging from your #2 picture it appears that the lift arm is not on the rockshaft all the way and the snap ring is not seated in the snap ring groove. Compare the right side lift arm to the left side and you should see the difference.

    I'd have to agree with Vern. In looking at your #2 picture, it doesn't appear that the snap ring is seated in it's groove. I wonder if applying pressure to the opposite side would push the rockshaft over far enough to allow the clip to engage the groove. Or, if maybe the arm pictured needs to be pressed onto the rockshaft further.

    That would of been mine, I agree the #2 picture doesn't look correct. You can't compare sides they are both different one side has two snap ring grooves in case you decide to add the mechanical lift for a mmm.
