Yup, time to change that one. Good catch. If (when) one of the 4 bearings that support either jackshaft or drive shaft fail completely while riding, it's a major PIA to get it back to trailer so paying close attention to them during maintenance cycles always pays off IMO.

For the cost of these bearings, IMO it's not worth taking the chance on any of those 4 bearings for the jackshaft or driveshaft. They are so important and critical that I just replace them with top quality bearings about every 2 seasons or so. I realize I've taken out "good" bearings but I like the peace of mind. Personally, I use SKF EMQ (electric motor quality). EMQ bearings have better finished raceways (more highly polished to reduce noise) than standard bearings. I notice that Cat calls out C3 fit bearings for the PTO side secondary clutch and caliper, and on the chain case side they call out standard fit. Maybe because both the chain case side bearings run in oil so they theoretically run cooler, and on the PTO side, the jackshaft bearing gets very hot courtesy of the exhaust manifold being very close by, and the brake disc heat being close to the caliper bearing.
