Reet. I have posted this on the F3 page but im getting no response...

I have a running problem with my F3.
Started making a horrendous rattle in the engine. So today ive swapped out my CCT for a manual one (tried using the same one in my f2, dont, its a different one, theyre not compatible)
And now its worse!!! too lose and it rattles its head off, too tight and it cuts the motor out.
Is the chain shot? are my cams kaput? am i missing something small?
wa gwarn

 

Found the problem!







Three of the four bolts that hold that alternator on had come out and destroyed.
The threads where they screw to the alternator cover are all knackered :/
So, what do i need to replace?





Metal filings from the screw's??

Do i need to replace this bit as well or not????


Any help appreciated !

 

Man, that sucks! I hope none of those shavings made their way into the rest of the oil, and if so, I hope none of it made it's way into the other oil passages.

If this were my bike, this is what I woud do: I would definitely NOT run the bike until the oil has been drained, the filter removed, the oil pan dropped and everything in the lower crankcase somehow "flushed" thoroughly. Then, I would put on a new filter, put in 2 1/2 quarts of some cheap-o oil, and one quart of a "motor flush", or "crankcase flush" - I'm not sure what products you have there... follow the instructions for the flush, and then drain, change filter again, and put in the preferred oil.

That's a lot of crap to do, and a few quid thrown away, and that might not even be enough insurance that there's no metal bits in the oil, but I personally would not go forward without doing that. And it might actually be total over-kill, as I'm not even certain what kind of oil pressure is built in that area, but if oil can get there through a passage, then debris could possibly get back through a passage, and I'd rather be paranoid and safe, then sorry, with a potential lump of scrap metal on my hands!

As far as replacing any parts in that area, assuming the rotor and stator are undamaged, including the internal threads in the stator cover, then it looks like all you need is four new bolts.

 

The threads are dead, completely so a new cover is required, hopefully picking one up tomorrow, and the, forgive me, I dont know the name of it. the circular part that currently has the metal filings in now is very very magnetic so im hoping that this part has collected any pieces of floater and I can 'scrape' it out of there. but I am going to change the filter and flush some oil through.


any ideas what could have caused such a disaster?

 

Yeah, that's your rotor, and I was going to say that hopefully it kinda "sucked up" a lot of those shavings, but the problem is, not everything in there is steel, the cover, for example, is aluminum, so the magnetic properties of the rotor won't help you there!!

 

Probably due to them not being torqued to spec, that would be my guess, a little medium thread-locker would be a good idea too... I definitely used that when I upgraded to my race cover.

 

All this expense...
I have two bikes and currently neither is on the road.

The summer has finally hit here in the uk and I can't get out. Eurghhhhhhh.

 

Still got problems!!!!



Fitted all the new parts
And it's still making the same
Noise!!! How is that possible.
I've stripped it allllll down again, annoying!
And now I've noticed this...


Is this the cause of my issues, what else could be making the noise so bad?

Worth while upgrade?

 

Well. If I've ever needed you guys. I need you now!

Sump plug snapped.



It turned enough to make the oil drip very slowly.
What the hell do I do now?!
