I bought this beast yesterday and have been tuning it up. It sat up for a couple of years and I imagine the slip clutch is frozen up. I cannot for the life of me see how to adjust it. I need to loosen it up and break it loose. Any help?
The big nut on the back of the clutch pack, closest to the gear box is what you adjust clutches with. IDK the proper foot pounds, I just keep mine snugged up good is all. It doesn't take a lot if the clutches are good.
Adjust the clutch using wrench #1 (part number GY2256W) in the diagram. A standard wrench can also be used.
Loosen the nut a bit.
Engage the tractor PTO a few times to make certain the disc are not stuck together(if they are, the engagement and disengagement will help to un-stick the disc).
Snug up the nut.
Place a mark on the housing(#10) and the holder(#8). Use a soap-stone, or a colored marker.
Engage the PTO.
Tighten the nut until the housing and hub turn together(no movement/slippage).
Back off on the nut until there is very little movement/slippage.
At this point, the clutches will slip when the blades comes into contact with as obstacle.
Thanks guys! I kept Assuming the adjustment was in the front. Lordy, that’s a big nut! Calipers say 2 1/2”. I have a big crescent I thought would do it. Nope. Looking like a pipe wrench now or a custom wrench out of steel plate.
I see the wrench in the parts diagram. Guess I can get it from Deere.
