Chain case site glass has Milkie color

[Apex1958]

I brought my sled to the dealer to have the 500 mile oil change and have the chain case adjusted and some other work done. First off only moved the adjustment screw on the chain case 2 ½ turns. But here is the problem when we looked at the site glass the oil HAD A MILKY COLOR TO IT. I am assuming its moisture that got into the oil from condensation. My dealer freaked out and took the cover off and cleaned everything and added Yamaha chain case oil and has a call into Yamaha. HAS ANYBODY ELSE NOTICE THIS?

That would be water to cause the milky color. I think Yamaha is going to regret getting into bed with AC. But that's just me!

Do you park the sled in a heated garage after every ride? If so that is probably where it is coming from.

 

[Apex1958]

Yes heated to 45 but at the end of a weekend I leave it outside until I leave camp. My Apex has been in the garge for years and the oil on the dip stick allways looked good.

X2 plus low. Added fluid and plan to change it out. Had to tighten chain too.

Cat uses self adjusting system. This yamaha system cat I feel overlooked when assembly.

Planning on changing might at oil change.

 

[Apex1958]

Familyman so you have noticed this also? Do you think the oil is crap that AC uses?

Agreed, it is worse if you leave a sled in the trailer closed up in the summer....I have seen more than one crank fail from rust that way. I would explain the physics behind it but Sled Dog says it is Arctic Cat issue so we must defer to his wisdom.

Stingray719 you started a thread to ask about the problems of the viper and you now want to defend AC on a Yamaha site, hmmmmm makes a person wonder. I have stored my yamaha sleds (3) in my 3 place trailer for 10 years now and have never seen the oil get milky from parking my sleds in their all summer and never lost a crank and where I live we gets lots of rain and high humidity along with very hot days. So yeah I am going to say this is a AC problem along with a bunch of the other problems this viper has seen. Why are all the chains so loose its like AC who built these sleds are setting them so this part fails.

Seal going bad allowing water in? I've stored sleds inside for upwards of 30 years and have never had chaincase oil get milky on me.

Yes Sled Dog , we get it! You don't like the Viper and the venture with Cat.

Yes seal gone bad make much more sense seeing how this sled has only been around for a month now. Water condensing not the problem!

You have bashed the Viper and Cat in your last two or three posts that is why I called you out on it. You bash this sled (Viper) and Cat every chance you get and add nothing to the conversation. Yamaha and Cat are partners get over it.

Hot days in Canada? Here in the western US parking a vehicle in an enclosed trailer cause condensation that wicks its way into gas tanks and crankshafts. The conditions have to be right but when they are this occurs. Having rebuilt more than a few of these when I worked at a Yamaha dealership long ago I do not feel the need to explain further. But here is an entire thread talking about trailer condensation - http://www.spyderlovers.com/forums/show ... for-winter

And look closely I have been a Yamaha fan for a long time, but I am also smart enough to see this partnership is good for Yamaha. Enough so I bought a new Yamaha Viper and would not have bought a new Yamaha without a competitive chassis. My 2014 M8 will probably go towards a Mountain Max next year, so save the "hmmm makes a person wonder" eh?

i had this problem with my 07 phazer when i got it..i could change the chaincase fluid and after 2 rides it was milky.. then a update was made by yamaha and it was to replace the gasket..never had an issue ever again over the next 4 yrs i owned the sled..

I also had the Phazer chain case gasket issue, didn't check for an update just silicon sealed it....lol

I've seen this happen on other mfg sleds. Polaris, Ski doo.

A buddy had a 600 ski doo that had tons of water in it.
I've seen a Polaris not move because of ice in the chain case from the moisture building up.

It all depends on how you store the sleds. A cold sled brought into a warm environment will produce condensation.
Until the sled equalizes to the room temperature.
Do enough cold heat cycles and you will get moisture build up.

When I store my sleds in my 4 place trailer in between trips I always leave a door open to eliminate the cold heat cycles that cause condensation build up and to get more ventalation in there.

It only takes a small amount of moisture in a chain case to create a milky color.

It usually will evaporate when the chain case gets warm and run hard.

Unless allot has built up then the oil should be changed.
