Stupid question time. A few days ago I did my "spring check up" on my MX6. Loosened the slip clutch, slipped it, checked the gear box oil, got underneath it (it was on jack stands and attached to the tractor with parking break and wheel chalks). The grease fitting on the U joints were at bad angles, so I ended up taking the little screw with the phillips head out to rotate and then slide the plastic sleeve down, move the plastic bell, and get to the U joints. While I had those off, I greased the white plastic that holds the safety shield on.
When you clean and grease the shaft, do you remove the plastic safety shield for the smaller shaft so you can grease it? That little screw in the plastic didn't look like it was good for a lot of removals and re-insertions. Or is it sufficient to put a blob of grease on the end as best you can and re-insert it?
Other PTO drive shafts I have use a quarter turn plastic screw, I can see where that would have a better lifetime than the little sheet metal screw in the MX6.
