Aaaaarrrrrrrggggghhhhh, I'm at a loss...HELP!!!

The way I understand it is that it had the knock before the clutch blew, is that right?.

It started after his clutch shat itself dragging at Ruapuna.

Fk me. I had something remotely useful to contribute to a mechanical thread.

i was trying to isolate the tapping sound on a machine , this machine happened to be about $200,000 worth so a fuck up wasnt gonna be tollerated , i ended up getting a sound meter and moved it round till i found the loudest area , it ended up being in the hermetically sealed part of the machine , i pulled it apart and got it bang on i found a loose baffle that was bouncing up and down in the 250psi gas rushing past it , i got the best welder i could find to help me piece it together and it was all a success.

now for your problem , have you tried a different brand or weight of oil , are you sure it aint a fracture or loose mount throwing you off,also i had a loose header pipe and it was leeaking and fuck it made the weirdest noise and it felt weird too

I know you don't want to hear this, but , I always try to diagnose before pulling down. might have to assemble.
Primary gears , damaged , loose ???? Had that on an old yamaha once , replaced a bearing three times before finding one loose ! Gaz.

Does it get louder (or quieter) when the engine warms up?

And are ALL the engine mount bolts actually doing their job? no slogged out mount holes?

Well I have found the problem,

the primary gear on the crank has 2 bent teeth, not bent enough to see but enough to measure, unfortunatly the gear is also part of the crank so unless I can get it repaired, im up for a new crank.......

Thanks for all ya help guys

I wouldnt think so, they are big case hardend teeth.

So,with hindsight we can see it all makes sense....and all the clues were there,not so difficult afterall.....in hindsight.....

Hindsight's a beautiful thing, but not very usefull.

[Motu]

WHAAAATTT????? It's THE most usefull thing in the world of diagnostics!!!!! And we can now all learn from this - or don't you want to? Learning from your mistakes and applying them in the future is soooo old fashioned????

[scumdog]

Yup, my 20-20 hindsight has stood me in good stead throughout life too!!

Fully agree, what magua was saying is that hindsight is not usefull to him- hes bit of a slow one.
