Man my big bear give me a hard time, I was out the country for 2 years and left it behind to 2 friends that was less mechanically incline that I thought. What I thought was going to be a simple timing chain and exaust valve job turned out to be a absolute complete overhaul, and I cant find a manual for my bigbear because it is a special edition release only in canada in 2000. You just saved my day.
Hey I know this is an older video, but having a problem with excess oil getting into my middle gear drive. When I remove the fill cap to the middle gear box, oil just starts poring out. When I change the oil, I put the right amount in the middle gear drive the manual calls for, and it is fine. I run the atv for a minute then shut it off and let it sit for a couple of minutes. Then When I open the fill cap, oil starts gushing out. l I am assuming there is a seal or O-ring that is worn between the crankcase and the middle gear drive that is letting more oil overfill it. Any ideas where this seal is or how to get to it? Thanks
Mine does the same thing. I'm sure the oil that's in the middle drive gear housing mixes with the crankcase oil. The fill plug that you refer to, is a plug used to initially fill the middle drive after an oil change. It should take about a half a court. After you put the initial oil in the drive you shouldn't have to worry about it again. The oil is mixed with the crankcase oil and is checked at your engine dipstick. I hope I'm right. I hope that helps.
If you have to use a hammer to remove an axle shaft ALWAYS put the castle nut back onto the axle BSCKWARDS to protect the wheel hub's threads And the castle part of the nut.. BEFORE hitting it. You'll prevent the axle from getting thread damage. The nut gives you more surface area to strike and wont deform the end to where you cant get the nut back on.
Was yours leaking into the boot that covers the u joint? Mine is leaking somewhere and it fills the front of the protective boot around the u joint. I jacked the quad up and put it in gear and let it run in gear and I pulled back the boot and it wasn’t leaking out of there. It actually looks like it’s leaking from the cover that bolts onto the jug. Can that cover that bolts onto the jug be removed with out doing all this? Like the seal around the cover is bad
How difficult was it to remove the u joint? Mine is leaking here....I'm debating removing the front U joint and trying to tighten the nut that way first.

do you need a gasket in between the two halfs of the drive gear?

Any idea where to order that seal? I’ve got the same problem .. is it called a drive gear seal?

It's alot easier to try that first. Should only take about an hour. Depending if you have ever done it before.

I normally use Partzilla to get the OEM part number then copy that into Rocky Mountain ATV or my local dealership. Don't cheap out on seals. 😃
