I discovered that I am missing a grease fitting on the right rear wheel, it must of broke off. how the hell do you get out rest of fitting, drill it? Also impossible to get a drill in correctly to drill it, so looks as if control arm needs to be disassembled, ofcoarse it would have to be a PITA fix.

I noticed earlier today when my sister was riding the atv, that a squeeking noise was coming from right rear wheel, i assume it needs grease which is impossible for the fittings to take in grease for some reason. I remember starting a thread about this awhile back, and some people recommended using a better type of grease fitting vs stock fittings? Zerk fitting was it?

Also how important would you guys say it is to keep these areas greased? I try getting grease in, and I can feel end of grease gun fitting onto grease fitting, but grease shoots out around outer part of fitting. I then shoot grease around inside of spindle (or whatever they call it) right before wheel where there is a rubber boot around it, so grease hopefully gets in there. I was just wondering how critical it is to get grease in there and if it should break, I assume it would be an expensive fix? When i purchased atv, they did give me a free tune up which I never cashed in yet. I never had valves adjusted yet and have over 430 miles on it, and was deciding maybe i should schedule to bring in the atv for a tune up/ maintence session they do? What do the yamaha dealers usually hit you for something like this? I know they charge alot of money to work on atv's and motorcycles.

 

It is not hard to take things apart enough to get to this area. On mine I replaced both fittings with 90 degree fittings. Now they face forwards or backwards so it is easier to grease them. When you put the grease gun on the fitting is is often hard to keep the grease from oozing out where it shouldn't. Some pressure on the grease gun tip and changing the angle towards where the grease is oozing should help.

To get the broken one out you need to be careful. They make easy outs just for that kind of thing. You don't want to ruin the threads or get bits of metal pushed in with the grease. A grease fitting is also called a zerk fitting. Depending on what shape the broken piece is you might be able to get a hold of it and turn it out. Maybe a small screw driver will make it turn. Once you remove the wheel and the two bolts that are being greased, you will be able to get better access to the broken piece. If you can't get it out your self, you might be able to take it apart that far and then take the quad to a machine shop that can remove the broken piece. I am just not sure if you can get enough room to work without the rear knuckle being pulled off the shaft. If there is enough room it shouldn't be too bad of a fix.

Have you greased the drive shafts?

 

I can't get the grease gun to access the drive shafts fittings. I know what you are talking about the 90 degree fittings, i'll have to go to the auto parts store near me and see if they have any. Is there a certain size i would need, or does one size fit all?

 

There are different sizes. I am not sure exactly which is right. If you pull out one you should be able to match it up. I can't get a regular grease gun on the front shaft. I have a special tip for the grease gun. It isn't great but it is better than no grease.

 

I bought a special tip so I can get into that area, it's a hose that fits on the end. Problem is you need at least 1-2 hands on end of tip so that tip stays on fitting, and another hand to pump grease. I guess if you are related to an octopus it would be no problem. I usually just wind up using WD40 or fluid film on shaft seeing how it's impossible to get a grease in there.

 

This goes onto the end of my regular grease gun hose. Mine has a flexible hose. It has a tip shaped like a funnel. I press it against the grease fitting. A lot of grease leaks out but I am able to get grease to go in. You have to rotate the shaft until the fitting faces the right way.

 

So that peice works alot better then an extension hose would? I bougth the extension hose, hoping it would solve the problem of reaching tight areas. It reaches fine, but you cannot put pressure on the hose because it is well, a hose. With that extension seeing it's all steal, you could put pressure on the extension and be able to pump the grease gun.

I'm gonna attempt to try to take off a fitting and go down to auto parts store and see if they have the better fittings. I have no idea how the hell I would be able to get the one off of the shaft, there is not alot of room to get in there and take it off.

 

BTW, what about broken fittings? How the hell do you take then rest of the fitting out that broke off and is threaded in the hole?

 

I got the new fottings, but cannot get them in. So I said the hell with it and dropped off the atv at the yamaha dealer. Also they will do the free service tune up i had gotten when I bought the atv. Also getting a moose clutch kit installed, so I'll have better torque. $149 for the clutch kit which was not bad, plus labor. I am never touching anything again, not even taking off a tire on the atv. I dont care if it cost $1 million dollars, never again will i ever attempted to fix something, I only wind up having stuff break, like the stupid tire stud bolt which kept falling out when I tried putting the tire back on. I almost took a sledge hammer to the atv cause I was so mad.

Then I was looking at 09 grizz 700 efi power stearing, with no winch. $8459 new. They would give me $3500 for my 450 and $1200 for my KLR250 which I never ever use, then would be looking at a $4500 difference for a brand new 09 700 and the winch was $400 with 20 percent off. Oh yeah, it was a camo grizzely like DS2's. But the guy was tellling me I should be real happy with the clutch kit as it will give me back the torque I've been missing since adding bigger tires and then some. He also told me that the air breather for the carb could have played a role in the stalling in the water, hoses could be clogged with mud, or even shot. He said I could put a longer hose on and redirect them to front of atv and have them stick up in front of instrument cluster.

 

At the end of the flex hose is a metal tip that attaches to the grease fitting. The part in the photo I put up also attaches to the end of the hose. There actually is a grease fitting on the bottom of it so it will hook up to the end of your flex hose. I just wanted to clear that up for others that may want to use one.
