[Ultrasauras]

What do you use to seal the crank haves.

thanks

YamaBond

What do you use to seal the crank haves.

thanks

YAMABOND, non-hardening

^^^what Kraven said^^^

thin film is all it takes...you dont want a bunch of extra squeezing into the crank and bearing cavities.

I use 1211.

Threebond.... 1211. I like it alot better than Yamabond, but Yamabond is still a great product.

You use 1211 on the case halves? I don't use that, too thick for my liking. I use 1194 for the case halves and then 1211 on base gaskets.

I use 1211 for anything that needs sealed up

purple loctite, it's an anaerobic sealant, goes on thin never had any problems.

In 2005 up to the 2008 manuals Polaris calls for Three bond 1215...(part #2871557)

In the new manual printed this year (2007 - 2011 IQ service manual PN 9922854) Polaris calls for Three Bond 1217 H... It has different properties than the 1211. The 1211 is fluidic and not resistant to sag like the 1217H.

The 1211 has a surface drying time of 90min...1215 60 min... the 1217H 5 minutes.

The elongation properties of both are radically different between the 1211 and 1217H.

At a given fastener torque on the case halves.. the difference in viscosity might make a difference in bearing crush or bearing clearances or give more consistent results .

I'd like to know if someone on here can chime in that has hands on experience with both 1211 and 1217H... and tell us what the tech differences mean "in use"

1217H
Has excellent resistance to engine oils such as SJ-oil.

Has excellent initial resistance to pressure.

Has high elongation and withstands vibration well.

Has excellent resistance to heat and cold.

Retains the elasticity of rubber in a wide range of temperatures,
from -60°C to 200°C or even, briefly, to 250°C.

Is a deoxime type and does not sag.

Used for sealing of surfaces such as those of oil pans of automobile
engines, chain cases, and oil pumps.

1215
General-purpose liquid gaskets.

Excellent engine-oil resistance.

Excellent gear-oil resistance.

Corrodes copper and copper-based alloys. Can not be used for
copper and copper-based alloys in tightly-sealed state.

1211

Low viscosity, fluidic, and excellent workability.

Can be used with solid gaskets and it can be used for temporary fixing
of O rings.

Corrodes copper and copper-based alloys. Can not be used for copper
and copper-based alloys in tightly-sealed state.

Sledguy... I know you do your homework on this kind of stuff... Sincere question here... Isn't the 1194 for High clearance flange and thread assemblies for its "padding" properties?

Now you are going to go make me look at the tube.

I'm pretty sure its 1194, grey like Yamaha bond. On a case half, because it is semi drying is all, it squishes out. I use the thinnest of films of it on one case half and then stick it together.

Anerobic Sealant!!! Take your pick on the brand but I prefer Loctite's. It Absorbs vibration and shock that the other stuff doesn't after it has been in use a while. It seals instantly with zero oxygen. All the OE's are using it now and it is taking work away from me. Sled manufactuer's are a little behind but they will get there soon. Don't get me wrong, Yamabond, 1211 is good stuff but something better has come down the pike. I use it on head bolt flanges also.
