why would the 80w90 oil mess up my rear diff?
i think im going to just keep it in there in less i can find a oil like mobil 424 and kawachem wet brake fluid because my dealer doesnt carry either. Is there a substitute with the same properties as each.

 

You ought to keep posting your questions under one topic instead of starting a new topic every time.
Packardbell - have you bothered to read your owners manual yet? It says Mobil 424 - there are no substitutes. That should say it all. Your dealer is stupid; find another. If for some reason you can't find Mobil 424 or a Kawi dealer with the right Kawachem, go to a tractor supply store and tell them what you're looking for. They probably have a sub for Mobil 424.
As far as the 80w90 harming anything, if you have ever driven a 650 at speed for any amount of time and then touched the rear gear housing, you will find that it's extremely hot. And that's with the water thin Mobil 424 in it! How hot do you think it will get with 80w90 trying to work it's way between the braking plates. It could damage the braking plates and other related hardware. The 80w90 will also break down from the heat and there goes your bearings. But it's your money, do what you want, I don't think there is anymore information that we can come up with that will change your mind. Let us know if you decide to pour out that molasses and put in the right stuff. If you leave in the 80w90, let us know how much the repair bill is in a week, month, year? Don't know when, but it will happen.

 

yeh im going to have to geta new oil. My dealer is being a as*hole. Im going to get that wet brake fluid and oh well if he doesnt have it there is a tractor dealer right up the hill from it.

 

Now your talkin' ![img]i/expressions/face-icon-small-smile.gif[/img]

 

yeh!!!
do u have any experience with ordering parts from the dealer? Do u know how long it would take the plug for the front trans to come in? i broke it as i explained in previous thread.

 

I sell Mobil and 424 isn't offered in quarts. I'm not sure what spec's Kawasaki is looking for but my guess is that any wet brake tractor fluid will probably work just fine.

 

By the way the 80w90 has the viscosity equal to a 50 weight motor oil, the 424 is more like a 10 weight. The only problem with the 80w90 is that it will effect your braking.

 

thanks alot for the reply.
the first time i got some new holland hydraulic oil for wet brakes because they didnt have it and now they are being ignorant and not giving me the right kind.

 

Hey guys. I found this topic rather interesting and upon some further research (i had nothing else to do, lol) , i found that Amsoil also produces a hydrualic oil that meets the same manufactures specs as mobil424. If anyone else is interested here are the links to mobil and amsoil sights that list the specs[img]i/expressions/face-icon-small-smile.gif[/img]

I'm still saving up for my p-650[img]i/expressions/face-icon-small-happy.gif[/img] can't wait...hopefully will be able to get one in spring!

 

Mobil 424 is a transmission/differential/wet brake fluid and if memory serves me well it cross references to a John Deere J20 type fluid. I checked in on it and it was about the same price as the 424, so I just bought 5 gal. of the 424 for about $30 and split it with a guy @ work that has a 650. Any bulk oil dealler can cross reference it for you. Or go to a heavy machinery dealler like Catepillar thats where I got mine.
