Imagine my excitment as i found lots of little shards of metal in the bottom of the clutch case of my newly aquired tzr, then finding that they are bits of a crunched crank oilseal. Should i burn down the sellers house or could there be a non main bearing related cause for a spectacular oilseal explosion. The engine dose seem to turn over well but i dont want to take the clutch off incase it is serious and i do have to chuck it back through his window http://hovercraft.org.uk/images/icons/smiley_icons/icon_lol.gif



And could the engine have been running well with this, i think not but just wanted to know before i ring him up...



Thanks

having just had the cage of a TZR main bearing break up, that could easily rip out the oil seal - if the oil seal has gone the bike would have run very poorly indeed - if he said it was a good runner brfore you got it i think you have a case



my engine was still running with the broken cage



the other thing is the gear next to the oil seal breaking up but that's highly unlikley and would feel rough turning the engine over



good luck

Having looked furthur i cant find any trace of the c-ring that is meant to retain the oil seal- if someone forgot to put it in then this could have caused the damage and would seem pretty trivial, but bits could have got into the bearing+engine and wrecked it.



Its just that its such a hassle to take it back but it will be even more of a hassle if i have to keep throwing money at it.

I think its just RGVs that money gets thrown at... http://hovercraft.org.uk/images/icons/smiley_icons/icon_lol.gif

the C ring holds the bearing in place, you only see the C ring when you split it, if it's not been fitted there's a chance of the bearings drifting but unlikely to push the seal out



either the seal was fitted incorrectly from the start or somethings happened to the main bearing on the other side of the seal



again good luck
