had the same noise from my 2002 280 pro i bought as a non runner for a lot of years, so decided to change the main bearings and seals but when rebuild and started it sounded like a bag of bolts and my heart sank but after i strip the clutch side off notice under close inspetion that the basket and crank gear had marks on them as something must of came loose at one time and causing the damage,got the dremel out and clean the damage up on the gear wheels the best i could and rebuild and started,this cut the noise down by half but now i know what to replace when i get the ££££££ in

just to let others know the problem i have had it might help others with same systoms i done a rebuild off the bottom end off a 2002 280 pro i got cheap as it was sieze with corosion round the fly wheel while sitting damp over a few years,i build her back up and when tried to start she give a couple of revs and stopped but would not start but back fire which was saying to me that timing was not right,checked wiring plug etc but could not find a problem as i was getting a spark and carb seem to be good so decided to take fly wheel off and found that woodruff key had sheared off in 2 halfs

sorted, took it to my local dealer and he used a punch down the centre of the crank and a few blows with me holding it to let crank fall out off casing into my hand and no damage done think the problem may have come a bout with someone hitting the end of the crank and getting a mushroom effect while fitting the gear wheel on !!

i am in the middle of stripping my engine to replace the main bearings but the gear wheel on the water pump side does not want to come off,i have removed the c clip but the gear is stuck fast and dont want to force it to much any ideas colin

First thing I would try is to run a tap into the threads to see if that would sort it,it really depends on how far you went and you might get away with cleaning the threads
