Sorry ignore this - there is a Huge crack on the other side - im going to replace it


I am I the process of checking everything after my recent purchase and have found the PO has cracked the CVT cover and the bearing looks like it is damaged too

My question is - does it matter that much or am I worrying about nothing
Also would this cause vibration I just don't know is all so looking for some "expert" guidance


Thanks

Here's some pictures The outside, the inside of the crack, looks like its gouged here probably trying to get the bearing out, and the bearing a bit fuzzy but you can see the damage I hope

Sorta looks like stress fractures........!!!! I looked at all the pics and I would just lube up the insert in the CVT case where the bearing goes......and hope for the best...... Personally - I THINK IT IS FINE.......

thanks for the input do these 2 pics (one of the bearing damage and one of the larger crack I found - still look ok)

I was getting very bad vibration when accelerating so wondered if this was causing that
again appreciate the thoughts

To me, the larger crack looks pretty deep.

Maybe we have some metalurgist on the forum who will weigh in on this.

It's probably ok, but I wouldn't want to do any long trips with all the cracks and outer bearing damage.

This is just my opinion.

As you probably guessed I am leaning that way too, I will order the part and swap it when I get it - course it made my great deal not so great as that case is almost $200

On the Outer bearing - how do you pull that off off the clutch bell - do I need a puller - I couldn't see any posts on that particular process - thanks in advance

I love the people on this forum always willing to help a "worry wart" out :)

cracks never get any better, especially when under heat and vibration,so it is going to get worse, slowly or suddenly, who knows, the bearing will/ should require a straight pull to get it off the shaft, a puller would be recommended, auto zone has pullers they will let you borrow, of course they also sell them and it's always fun to add a new tool to the collection. but concerning the bearing and the crack, the bearing is put in the case in an exact position to line up on the shaft to go back on, the case is damaged and the lineup may be no longer true causing binding while installing AND while bearing is rotating,(or trying to) vibration, heating and possibly the 4th world war being the result, or nothing at all,
Suzuki engineers felt it was necessary to add that enormous thing out there to give the shaft a support and strength point, so it probably should be aligned correctly, since the po obviously did all his maintenance with a hammer and a doberman pinscher don't assume he/she drinks good quality beer either, decline any barbecue invitations or birthday parties.

I suspect someone that did not know what they were doing as removed it
with the help of a big hammer, I would replace both.

You can have that aluminum case heli-arced much cheaper than a new case..and just replace the bearing......

nearly 17k now - I am pretty much doing everything, replacing all fluids,for the exact reasons you state
I think the reason its in this condition is because he did change the belt at 14k - I suspect all this damage was getting to the belt - I think he did fluids cos he gave me some extra filters, orings etc

I will also be changing the brake pads and anything else I can find, checking torques etc, will probably do a valve check too

I would not recommend welding as the bearing housing alignment is critical the current damage is the cause of your vibration and it appears that someone tried to pull it apart without knowing what they were doing. replace bearing and housing will save future headaches.
my job before retiring was fixing airframes and systems on airplanes so what you show in your photos is familiar to me.

the brake pads on the 08 have a groove for wear that you can inspect without tearing anything up, changing pads unnecessarily is like giving your wife jewelry for no reason, expensive, time consuming and bound to cause trouble, (she will think you are feeling guilty about something, therefore you must be guilty of something and she WILL find out what) or second worse, she will start expecting you to do it more often and you won't be able to afford to give it to your girlfriend , not only that, the brakes usually drag a while and make noise while they wear in.

Just to close this off - I got the parts from bikebandit - ama discount - and installed last night - all good, hardest part was installing the bearing but its all there now - did a run to dmv today and back and it seems much better

I wonder what would have happened if you just took the bearing off and put cover back on and ran it? Smaller scooters do not have a bearing on the outside of the clutch, I wonder why the 400 has this setup?

^^^ More torque? And if it wasn't needed or didn't have any stress on it, then you should be able to run it even if it was cracked.
