Title: How I fixed the hole in my motor.
Post by: 04monsterduc on October 19, 2011, 12:50:43 PM
When I bought my monster "04 1000" it had a hole in the bottom of the motor.  Both sides of the case were affected, and they wanted $4000 for both cases. I said screw that and made this with the help of my uncle.


Quick easy fix, and it has been working for 2 years now.

Impressive!  [beer]

Got any more pics?

What adhesive/sealant did you use?

Whoa!!!  I did the same thing to an Interceptor 500 motor that blew a rod out the case, and sealed it with JB Weld (it never ran again, but seems like it would've).  Drilling little holes in alloy cases is surprisingly easy.  I used bolts though, should've used rivets.

What did you use to seal it?

I used high temp RTV silcone. Worked great. Unfortunately I don't have more pics of the motor fix, but I did post these http://www.ducatimonsterforum.org/index.php?topic=53140.0 (http://www.ducatimonsterforum.org/index.php?topic=53140.0)

Great job.  I missed your thread the first time about your bike rebuild, thanks for the link.  Not many guys have built their own bikes and it's really something to be proud of.

Yeah, looks like the rebuild is coming out great.  Always nice to see a Monster saved from the grave.   I didn't connect the threads either. 

If the bike was mine I wonder if I would leave the patch the way it is, kind of like a badge of courage, or try to pretty it up some.  Have you decided which way to go 04monsterduc?

So far i have left the patch this way for the past 2 years. It only leaks a lil oil when it is cold outside. I have been looking at getting a new motor, but those are hard to come by, and money is tight. I do see it as a badge of honor and I see the hole bike as that. Ive put over 6000 miles on it over the past couple of years, and plan on putting a lot more on it. [evil]

nice job.


I picked up a crashed monster a couple years back and patched this hole with JB weld and it's also held up for 2 years without leak or issue. Looks like your job was a little bigger however.

A two part epoxy. One part 'magic' and the other part 'somewhat more magic.'

Yes jb weld is awesome. Think of it as plumbers putty but for mechanics. Ive used it on radiators, manifolds and exhausts forever.

The stuff is amazing.  Yes, it is available in Australia.

The JB only let me down once - header heatshield broke off on the 1098, so I carefully crafted a mount directly on the header.  Wow that didn't work at all, burnt to a crisp in 5 minutes!

Post by: Punx Clever on October 20, 2011, 09:05:57 PM
Yeah, but it says right on the package that it wont work on exhausts or other parts that regularly exceed 500*F.

Basically, JB weld is a 2-part epoxy with metal in it.  Think of it as the equivalent of wood-filler.

Correct. I dont do any bloody wrenching mate.  I use spanners  [cheeky]. 

And if I'm ever retching, I'd say I was crook in the guts.

I put petrol in my petrol tank.  And tire is something I do if I work too much.  On the other hand the car's spare tyre is kept in the boot.  Elephants have trunks.  Its a big wide world, much of it outside of NYC :-*.

Aha... special 2-part epoxy, eh?  Thanks, gotta find some. Just in case [thumbsup].

Yeah, I hear all of America yelling its virtues regularly.  Finally figured I'd ask what it actually is, so that I can get hold of whatever the local brand name version is.

Really?  I've never seen it.... maybe I need to get out more  ;).

Since, like He Man, I live in New York and we New Yorkers have a limited view of the world   http://bigthink.com/ideas/21121 (http://bigthink.com/ideas/21121) :P  I googled "jb weld australia"  and came up with a bunch of stuff.  Easily available?  Dunno.  Might even be black market for all I know, but it is there.

ive seen a version of it called "Q bond" on the counter at the local bursons but not the "jb weld" brand. its really handy stuff for adventurists to do some bush mechanic work with. they have examples of busted water pumps, engine cases, pulleys, all sorts of ferrous metal castings.

I have fixed so many things with JB weld, I can't remember them all.
To this day, over a year passed and my boat outboard engine cowling fix is still doing great. 
Can't really get a picture because it's in a nook, but I used a small aluminum plate and filled with JB weld all around, above and below it.  Holds up amazing!
More is better with that stuff, just sand it down once it's dry.

JB Weld does not work on holes in gas tanks a million miles (1,610,000 km) from nowhere.  [bang]
