Cracked Sump - leaking oil - UPDATED

[CVSensei]

So I just started the first oil change on my brand new MT-07.

Changed filter no problem.

Drained oil no problem.

Went to tighten up the bolt when I noticed there was a crack about 4cm long running underneath the casing. https://imgur.com/A2x4Pq5

I'm sure I didn't over tighten it, I only have a tiny torque wrench and I hardly gave it any effort which makes me think it might have already been there and I just made it worse.

Spoke to dealer and Yamaha assist about warranty and both of them got very tight lipped when I said I was changing the oil myself.

They're picking it up in the morning to take it to the dealer to check it out - anyone have any advice?

Nothing constructive other then brace for an argument. Might be worth trying to see if this is a common issue on other bikes.

Is there a crush washer missing between the bolt and the engine case or can I just not see it?

Going by the state of the sump plug I'd say you over-tightened it and had the spanner slip off too. The dealer is going to say it's user-inflicted damage IMO

Yamaha won't replace that

Sump for me is done up with fingers until washer presses against casing and maybe, just maybe 1/8 turn. 1 finger at end of spanner/ratchet. No more should be needed.

Can you buy just the sump...

First oil change. Y u no free dealer.

If it wasn't oozing oil out before you've more than likely done it yourself 'tightening it up'.

[spannermonkey...]

It's been Over tightened, mechanics don't lie. What torque is your sump plug, you'll be surprised you can over torque very easy. You should a crushable washer to seal the bolt between the sump, copper or bonded washer type. Best bet to source a replacement sump and fit that. Unless you can find a man who can weld alloy.

Because you've serviced it yourself the warranty many not be covered as the dealers like to do everything and charge a fortune for doing not a lot.

I've been there and done this myself on a Suzuki a few years back, cracked the sump and stripped the thread. I learnt my lesson, young and stupid and brought a torque wrench best thing in the tool box.

Actually, having taken another look at it, It looks like a bolt that has been wrung-off with a six-sided socket in a nut gun. If it really was as tight as you say then the damage could have been done by the monkey that assembled from the crate. Unfortunately, you're never going to get the dealer to admit to it all the time you have a hole in your, err, sump.

Had another look and it does actually have the washer.

I just don't understand how if I really did damage it myself by over tightening then how did the monkey who put it together not crack it? It may as well have been welded together I had to put all my body weight on it to loosen it at all!

I kinda figured I'm in the shit now regarding the warranty. Guess I just gotta take that hit. Worst part about it though is this is the first of my 10 day holiday and the dealer has estimated a minimum of 3 weeks to fix it. /Sigh

Buy new sump, fit new sump.

Good news - New sump is only £76.55 plus vat.
Bad news - they are on back-order.

Shame, coz I was just going to offer to weld it up for you whilst they order up a new sump.

I'm surprised that the threads didn't strip before it cracked.

[Taught2BCauti...]

Wouldn't the first oil change normally be done by the dealer as part of the first free service? Just curious as to what motivated you to do it yourself.

I use a 4" long 1/4" drive ratchet for tightening drain bolts - even the smallest torque wrench on the lowest setting could be too much (unless it's a good 'un).

Never seen a sump go like that though, without stripping the threads as well, so my guess is material failure.
