Hoping for some advice from those knowledgable regarding welding. A used 1995 m900 monster I just purchased has turned out to have a rather large crack along the entirety of the front engine mount. It looks like it had been badly repaired and is now coming undone. I can see pieces of the underlying mounting bolt on the left side of the bike. Given that this is an area which bears the majority of the stress/load of the bike I am wondering if simple welding can fix this. Any help would be greatly appreciated. I could just freaking kick myself in the head with the headaches buying this bike has caused me. I'll have to remember to go "new" or almost new next time. Thanks.

Well....that's certainly bad. Not safe to ride in that condition. :'( :'(

I have no FHE on how well the Ducati crancases weld. I've seen some cast aluminum welded, and it looks absolutely perfect. Other cast aluminum doesn't weld worth a damn. Depends on the alloy and such.

One guy here on the BB had a bad crack in the right rear motormount, and he got it welded up. That was fairly recently, so he doesn't have a lot of miles on it yet. Time will tell there.

I think it could be fixed by a talented welder/fabricator. It may require stripping the motor down to the bare crankcase halves to do it properly. From your profile, I see that you're located about in the center of the NASCAR community, right? Perhaps some asking around at the local race shops can lead you to somebody who is experienced at performing this kind of repair successfully.

There are probably folks here who have seen this kind of damage, and who may have more info than I.

It's a disheartening situation, and I wish I had more feedback for you. Don't give up yet, there's a lot of knowledgable folks here, and lots of spare parts that people have. Crankcases aren't commonly seen as spares, but you never know. Please let us know how it goes.

If it turns out that it's a bigger project than you're willing or able to deal with, there may be a couple of folks here who would be willing to try to do something with it. Worst comes to worst, I believe you could part the bike out to the folks on this BB. I know that's not really what you want to hear, and I hesitated before writing it, but I did want to give you the whole story as I see it. I'm offering it in the spirit of support, and definitely not the intent of taking advantage.

If you've got any more questions, fire away.

It also depends on the person who does the welding. From what I know, id say this is repairable.

It absolutely has to be stripped down to the case. After that it needs cleaned, and the crack ground out to allow the addition of filler metal. It also needs final cleaning with aluminum prep (chemical) or a stainless steel wire brush. Anything else will leave behind contaminants that will compromise the quality of the weld. The suggestion of seaking out a qualified welder in the NASCAR community is a great one! Thats the first thing id do, and would probably work out well.

Good luck

Winstone,
I totally know how you feel. I too had a crack in my engine mount, and also on a 95 900m. must have been a bad year for casing manufacture.

Mine was on the rear through bolt. The crack went from the top of the casing (near the Crankcase breather) back through the bolt casing, around underneath, through the neutral switch hole & right to the centre line of the casing.

Your comment, from your pictures looks correct. Someone's had a half A$$ed attempt, or more likely not had the experience & had a go at the repair & left you with a nasty looking reconstruction job.

looks like on the clutch side of the bike, they have tried to repair weld the casing on the through hole & exposed it to too much heat causing the casing to collapse completely, this is why you can see the through bolt. The otherside is not as bad and hopefully will be easier to repair. Some sort of additional bracing (or Building up) will probably be required to prevent the crack re-appearing. I welded up the earth strap mount to give the casing another structural support web.

The side that has collapsed will need some serious & meticulous highly specialised welding. The problem with welding alloy is it show's no signs of getting to Melting point (drop point) if you keep the heat on it just a bit too long it will all of a sudden collapse in front of your eye's.

Taking the engine out is no big deal. Stripping the engine & parting the casings IS a big deal unless you are real confident with the spanners to get all back together right.

I managed to take the engine out myself & get it welded without pulling the casings apart. Mine's done i think about 3k since & no signs of failing. But i must say mine didn't need as much as what yours will.

my advise is take the engine out & take it to the Best, Most Experienced Mig & Tig Welder you can find. Get him to check it out & see if he will attempt the job. I reckon even if he has a crack at it he will say that he will not accept responsibility if the job fails or worse, if he further damages the casing. This is what i was faced with. I went with the deal as i had nothing to loose as if it worked (which it did) i'm back on the road with minimal outlay, but if it didn't then it would have had to go to the Duc Shop for new casings & a rebuild anyway.

I tried to search for the thread that pertained to my cracked casing, but unfortunately i can't seem to locate it. Maybe someone with better searching skills can find it. It was called "Devistated......What Next" There are some picks Before & after there.

The repair if it can be done won't be pretty, but i guess it comes down to spending a few hundred & putting up with the looks of the repair, or spending maybe Thousands & getting it right.

If you want to give me your private e-mail address i can send the pic's. (i'm no good at uploading stuff here)

Good luck & if there is anything else you need to know that may help, drop me a line. Get it out & get it to the welding Guru's!

Thanks everyone for the input.


Chris, I read your thread and it gave me some hope that I could get this fixed, but from what everyone is saying I think this might be over my head.

This is my first bike and I'm thinking that if I kept it I would be spending the majority of the summer trying to fix it instead of learning to ride.

It's really disheartening that someone would sell a bike like this, especially someone on this board to someone so new and unfamiliar to bikes, but I guess that's just the way it goes sometimes.

http://www.ducatimonster.org/cgi-bin/classifieds/classifieds.cgi?search_and_display_db_button=on&db_id=599&query=retrieval

On the plus side of things, I'm really happy to have found such a great group of people who are willing to take time out and give some great advice.

Anyone know of anybody wanting a Monster with a cracked engine casing? I'll let it go cheap.

It looks like it had been badly repaired and is now coming undone.
Given that the repair material is on top of the paint, it looks more to me like an attempt to hide the crack, than an attempt to repair it.

And given that the seller, Jim Perry, has described the bike as in "good condition", I would ask for my money back. If he refuses, I would get a repair estimate from the local Ducati dealer, and take him straight to small claims court.

From his DML ad:
...seems to need jetting for now stock exhausts...

If the below is your seller, he seems to be a seasoned motorcycle owner, and it sure looks to me like he is guilty of intentionally screwing a newbie:

Good luck.

cobradoc, if you like the rest of the bike, you may want to look at a complete used motor to drop in that one. Try woundedduc.com to see if they have one in stock. Scan Ebay and other ads for wrecked Ducs to lift an engine out of.

Tom,

That would be his ebay auction. Interestingly enough, he said that there were after market exhausts on the bike which had been removed by the previous owner. (He had just obtained the bike before he sold it to me) The guy had seven bikes at his house and told me he had been riding for several years. He absolutely assured me that this bike was both mechanically and structually sound. If I bought the bike "as is", do I have a leg to stand on in small claims court?

People on the DML are supposed to have higher moral standards than other boards. The guy who sold it to you MUST make it right. That being said, I'm a lousy aluminum welder myself, but I have seen plenty of repairs that would render the area better than new. Try to have it fixed locally, if you need a set of cases to tide you over, I have some good ones you can borrow. If you decide to sell it, let me know, I'm always on the prowl for "projects".

Winston,

I am not a lawyer, and "buyer beware" aside, from what the ad states, and from what you and your pictures describe, I would say yes---the guy flat out lied about the condition of the bike.

As to whether or not you "have a leg to stand on in small claims court", I would certainly give a judge the opportunity to answer that question for you---that's his job.

In my experience, the small claims court system is fair, but prepare yourself: Print a copy of the DML ad that describes the bike as in "good condition" before it gets deleted (like, NOW), take more pics, get that dealer estimate, then file and have Mr. Perry served. He knows he f*cked you, and just might surprise you with a phone call...but it sounds like you'll need the leverage.

BTW - I'm assuming that this was just an oversight by the seller & he's going to be very apologetic & make everthing right, but....in case he doesn't, you should post his name, address, & everything else you can find out about him.

Just to keep the ad from being deleted.



That is sh!tty a seasoned biker sold a new person that without fair warning.

This is testimony to the fact that there is some real low down scum bags around (& that's put lightly, no where near what i'd like to say)

The person responsible should be highlighted as a Shonk & a theif on every ducati board on the globe. Then his use of this board terminated & blocked.

I can't feel enough for you.

I still don't think looking at the pictures that this was an attempt to hide anything. More a totally butchered attempt to repair. There is a good hunk of aluminium missing where it has simply been over heated & dropped away like melted plastic. I compared it with mine (same year & model) & there's aserious hunk missing.

I know you'd be fairly cut at this point in time. But i urge you to take it to a specialist alloy welder & see if anything can be done before you make any rash decision's & flick it off.

You never know, someone might be able to get it right. Building up is a tedious job, bit by bit, so the heat doesen't get outa controll. But you still could, may be in the saddle for not too much money.

Then Take the Pr1ck to court!!

Sure there is laws protecting the seller in an "AS IS" contract.

But, There must also be a law to protect a buyer that Buys from a seller, where the seller states "Good condition Mechanically & Structurally" knowingly that he is outright blatently lying.

It's a bit like if you write a personal Cheque knowing that there is no funds in the account, you can be prosicuted for Fraud! This might be a good avenue. Again i'm no lawyer.

Hopefull one of the DML members is & can shed a bit of light on the subject for you.

I wish you well. keep us up to date as things develop.

Thanks everyone for the support. Like I said, a complete teardown would be over my head at this point in the game. I'll be taking it in today for an estimate. I had one of our JAG lawyers take a look at the situation, (I'm a Navy Flight Surgeon) and he thinks the case has legs, especially since the bike has virtually zero additonal miles from the title change and also the fact that the damage could have have caused serious loss of life or limb. I'm going to let the seller know he's got one chance to make things right before I file a claim for the price of the bike and additional damages. Don;t worry though I'll be back on a monster in the near future.

I wouldn't be surprised if he got took when he bought it and that's the reason for the short turn around. I also gotta believe if it was crashed hard enought to not only dent the tank but bust the motor mounts, that the frame is hosed as well, or quite possibly not even the original. I've bought and sold a lot of bikes in my time but have never seen one with a broken mount like that. That is a major hit. And he obviously tried to gas weld instead of TIG/MIG. Wrong way to attack that.

Asking price was $2750, what did you actually give?
If for that price or lower you got a hell of a deal regardless, wrecked bikes with non rebuildable titles go for more than that.

The dude may not have known, even if he did, on used sh!t it's buyer beware. It's the buyers responsibilty to make sure it meets their standard before buying, there is no warranty afterall!

Some people would make good, but don't be surprised if not. Take solace in the fact that if you paid $2700 or less you got a great deal on the bike even if you have to repair it.
