Kubota M5-111 water pump starting to weep, replace now or wait?
Noticed a slow wet spot around the water pump on my Kubota M5-111 and honestly it kinda stressed me out a little. Midsize farm tractor, mostly field work and bale moving. Coolant gets changed on schedule like it always has.
Tractor still runs fine, no overheating or anything. Just this damp spot near the pump that keeps coming back after I wipe it dry. Not dripping on the ground yet but its bugging me.
Now I'm worried about getting stuck right in the middle of busy season so I'm thinking about grabbing a spare pump just in case. But part of me feels like I'm probably overthinking it. Might not even be the pump, could be something else entirely, and then I'm just out money for no reason. The one on there now is aftermarket, swapped it maybe 3 years ago and its been fine until now.
Slow weep like this, would you swap it now or just run it?
