Default When to change clutch bell bearings

How do you guys gauge on when you need to change your clutch bell bearings? I have some J&T Ultimate bearings and I just pulled them out after 2 gallons to check them and they appear to be fine. My clutch bell spins really free. Are they still good to go for another gallon or is it time for them to be replaced? I don't race and just bash. Also, that's just dirt a little dirt in the race that wiped off pretty easily.

Honestly, I change them very often. I always put new ones before a race, if it is a big race or a long main I will put new ones during the weekend. I then reuse the old ones for practice, clean and oil. As soon as they start sounding loud or get considerable axial play, I throw them away. You can get lots of life from them if you clean them often, but since they cost 1$ I think it just isn't worth the risk.

Yes, as stated replace ofter, it is the cheapest way to ensure clutch longevity and prevent blown out bearings. Buying a bunch in a tube is a good practice. If in doubt, replace them.

I change mine about 45 mins to an hour of use. I generally get a 30 min main, practice and qualifiers out of my bearings.

I change mine every 1- to 1.5 race days (Usually about every hour to 1.5 hours of time). The only time I had a clutch bearing issue was when I went past that time frame. Sometimes I pull them out and they dont feel bad, but I still change them out anyways. It is a cheap assurance method.

Usually run a set for practice and race. Then change before the main and run that same set for practice and race the next week(or whenever I race again)..... and just repeat

Though they usually can be cleaned and oiled again with good results, if you're the least hesitant just change them, if the bearings goes out they can take the crank with them.

JT clutch bearings last a long time. Change them when they just start to get rough. Should get more than 45min from a set imo.

45 min of bashing? I don't race so I was just wondering what the signs are of them needing to be changed.

If you do not race then change when it got too much play, feeling gritty of has broken in pieces.

Yeah TKO all the way for sure, in the clutch now have been ran for 2 1/4 gallons so far, after an hour of constant use I take them out, clean them with a rag and see how they feel, oil them and get back on it, before with nearly all other bearings it was half-hour use and replace so very confident you would have the same results
