Blown up TE 310R

I guess you could hammer on the inner race but wouldn't expect that from the factory.

Wouldn't surprise me from guys who are hitting shots of espresso and grappa all day long.

Sorry about your motor. Sure was nice of those Italians to put shit bearings in our bikes.

i dont think that about the bearing being particularly a bag of shite, they are mostly sourced form skf and fafnir like all the other brands.... maybe just a little on the X-Lite side of the load spec......but then again there does not seem to be any trend in this particular bearing crapping out. It is a machine and machines with all their moving and loaded parts do fail.
Also as we know This motor by virtue of its design is not particularly a very robust design, its a lite weight race motor......you guys know what that means.

After further investigation it appears the upper timing chain sprocket/gear shaft bearing is the culprit. Bearing failed causing gear to shift and engine come out of time. Intake valves then hit piston head stopping engine. Luckily I don't see any obvious carnage. valves, piston, cams, gears etc. all look o.k. without field stripping engine down. Unfortunately still needs to come apart for full inspection to have any confidence in condition of other parts, bearings etc. Hopefully wont be that bad. Seems odd first bearing in line from the oil supply line is the one that fails?? You would think it would be the better lubricated of all in top end. I'm concerned if I take it somewhere other than say Zip Ty they will change out bearing and call it good without proper inspection of all parts potentially affected. Maybe I am just paranoid but confidence in the bike is a big part of riding for me especially riding alone some times. Wish me luck!

If you pop the head off the engine & remove the cams, you could try putting some light fluid (like petrol) in the ports & see if it leaks through the closed valves. That will tell you if they are bent/damaged, it is likley that they will be.

Getting the remains of the bearing out from inside the cases will harder....not sure where the pieces go in this model, someone else will, but if you are real lucky they'll come out the drain.

Fingers crossed dude.

You could also try George @ Uptite in Santa Ana, CA. 1 714 540-2920 m-sat 9-5. People ship him engines to rebuild in ice chests all sealed up with silver tape....;} Anyway, there would be no worries that he would thoroughly check it out and rebuild to better than new. I'm not sure anyone will get the parts very fast, unless they have them in stock and bearings from George will be better than stock if he has any doubts

Good luck

Well, I feel REALLY fortunate, becuase that bearing failure is exactly what happened to my '13 te310 with less then 500 miles on it-amazingly no other damage(I found pieces of the race when I did an oil change). Luckily my extended waranty covered most of the cost.

That's interesting and scary that it was the same bearing. I assume you saw something on the magnetic plug and investigated?? Wasn't all that easy to see that bearing I assume stealership found it for you?? Wish I had been as lucky but also good info for other 310r both TE and TXC owners. Pulled the trigger and sent off to Zip Ty for fix and what upgrades I can afford afterwards. 100$ shipping but at least its in motion. The old XR will get a few more miles in the meantime.
