resealing cases with threebond question

Hey,

1980 GS 550

How much threebond 1184 should I use when I'm resealing my cases? A thin bead? Huge globs?

Also, how much do I need to clean/polish/whatever the contact patches that will be mated?

Anyone have any photo ref or threads where this is explained? I tried search.

Thanks

A thin bead should be all you need, maybe 1/8" thick or even less. The cases are matched surfaces. Put it this way: one tube is known to go a few (3 or 4) cases.

Polish should not be needed, a slight roughness in the surface is not a problem. Surface should be clean as in free of oil/grease, try to get most of the old bond off.

the mating surfaces should be spotless and degreased. you do not want a "bead" of sealer, you need to smear it on the surface, making sure it covers all the area with no gaps.
 
Actually the 1207B is whats recommended for case sealing. Took me almost 2 months to get some from Suzuki..back order issue.
 
I used the 1207B, clean the surface with mineral spirits and apply a thin bead. Make sure to keep it off the bearing surfaces and out of the oil passages. Did you take those gears off the shafts and check them thoroughly?:rolleyes:

There is also Yamabond and Hondabond, usually available at your local dealers. Pretty sure they are made by Threebond.
 
I think the main thing is not to use too much of whatever you use. The excess which oozes out of the joint into the inside can make its way into the clutch, oil passages, ect.

I've been told quite a while ago that Suzukibond, Yamabond, Hondabond and Threebond are all the same.
Is this true? I can't prove it but can confirm that I have used Yamabond with success. :)

exactly, you will be surprised how much a "bead" will squish out over the sides. these are mated surfaces so barring any damage caused by prying apart etc. they are pretty much flush fitting.

even a smear will squish out a tiny bit
 
Thanks guys.

So will the 1184 not work? I've already purchased a tube but clearly I can wait for the 1207B to arrive if that's definitely better.

Any techniques for making sure the cases seal properly? I tried to dry-fit the cases back together just to make sure they would fit snuggly, and it looks like they don't want to mate without leaving a tiny gap. The guy in that youtube video seems to be using a case-mating tool, but is there such a thing for horizontally split cases?


Almarconi, the pliers needed to check those gears are in the mail right now. Thanks :)

Nearly anything should work as the cases should fit together so well it is barely even necessary to use a sealant. When you torque those 50 (or however many) bolts/nuts that gap should disappear unless the cases are damaged somehow or you have something assembled incorrectly. I used that grey, "high torque" permatex stuff from the auto parts store as directed.
 
quexpress..yes all three are the same as Three Bond 1184, 1194.

The difference from these and the 1207 B is that 1207B dries hard and the others..as you will read on their tubes..is a SEMI drying sealer.
 
My favorite is Three Bond 1211. I've had a tube for over 10 years, but I figured it was time for a fresh one. All the shops around town had 1184, Permatex, Yamabond, but I've had such good results with this stuff, I wanted to keep using what I'm familiar with.

Z1 sells it for $20ish.
 
I use the 1207B because of the many manuls i have cruised thru it seems to be mentioned and recommended a lot...thus my thinking is that if it is specifically mentioned by the factory...good enough for me!!!
 
I use 1194. Latest and greatest Threebond formula for sealing cases. Great stuff. As chuck said, it remains flexible so it won't crack and leak. Better than the OEM Threeebond stuff Suzuki used 30+ years ago I think. My first 850 had an oil leak from between the case halves. Make sure you spread an even coating over 100% of the case joint area.

Ed...I SO MUCH agree on the old plastic acting hard case sealer from the 70s!!!

Thi is the beauty of the 1207B..its dries hard but yet it isnt rock hard and plastic like when cured..Its like the perfect happy medium in a case sealer. Seals and almost never leaks, yet has that certain "flexability" to adjust for the contacting and expansion of the metals.
