^Si.
Heavy push type clutches wear the bearing, In this case, the bearing fell out likely because the builder made a mistake

also man i believe that was a mechanic problem because the only time i have seen that exact thing happen when the thrust bearings come out is when they were put in backwards and not getting the oil they need because the groove is not facing the crank and messing everything up.... this was not a clutch problem. one of the reasons mitsu went with a pull style clutch is to help prevent crankwalk good luck. JAM put thrust bearings in wrong on a member on here and is trying to blame everything else.... but themselves

i know right i mean it is not rocket science you just need to pay attention and double check and tripple check everything.and when you put thrust bearings in backwards guess what i guess you didnt double check or tripple check then lol.... to the OP good luck with your motor man if you lived closer to me i would sure give a helping hand i have built many 4g motors.

Hello!
Sideck did you ever find out what was the cause of the bearing failure?, I have the same problem, I install 6 months ago and HD act kit and flywheel, and now the crank pulley side thrust bearing is gone so im taking the engine out. Any advice will greatly and will be greatly appreciated.

I love how people always claim crank walk when clutches are installed and adjusted incorrectly. It has been a dsm fad for years and its so sad.
