little problem,here

[skyhookman]

I,m doing my drive shaft maint. Jerked the gear box, had about a teaspoon of gear oil in the end of the drive shaft. The houseing is perfectly dry, and there's no oil on the out side of the drive shaft. The fluid was good in the fill hole, just like I left it the last time I checked it. I haven't added any oil since. I changed it last year. Must be slow what ever is going on. Is there a vent hole in the gear box, might be making pressure and forceing by the seal, just guesing. Any ideals here. Thought about goeing from 80-w to 140 and keeping a close eye on it. I don't know. Sure hateing to tear the b---- down. Missed some good riding yesterday and today, darn thing. :(" title="" border="0"/>

I've only serviced mine once. So I'm not an expert, but a teaspoon sounds like too much as I recall.

Yes, there is a vent hole in the gear box. The blue arrow in the following pic shows about where it is.

Are you sure the tea spoon of oil wasn't the fliud the shaft lube is. That splin lube is a moly base and the fluid can separate.

The drive shaft should be dry... There is not supposed to be any gear oil or other loose oil in the shaft housing...

I sure wouldn't worry about a tea spoon of oil there either. A slow seep like that would be harmless 'if' it is????

Hi, I did the shaft drive service just before I put the bike away in storage for the winter. When I removed the final drive from the swing arm tube there was about an egg cup full of final drive oil in the swing arm tube at the joint where the final drive attaches.
I always filled the oil in the final drive with the bike upright and now think that was too much and will be following the advice of others and fill with the bike on the sidestand from now on. I am not sure yet if I am going to replace the seal or just leave it as is and see if there is oil in there next tire change. I usually change the final drive oil every engine oil change so it should not run dry even if the oil seal is leaking slightly. How long did it take for there to be an egg cup full of oil in there ? The driveshaft had not been serviced from new (37,000 kms) so I have no way of knowing.

I think it was final drive oil, it was the same color and smelled the same as the oil when I drained it before I took the drive off. The bike was up straight when I filled it last spring. I won't do that anymore. I'll check the vent hole and make sure its open. I think I.ll clean her up and greaser good and filler up the right way, and give it another go. I'll keep a close check on the oil level and make sure it doesn't go dry. Is there suppose to be grease on the big gear that goes in the wheel. Mine's as dry as a powder house, no grease at all. Thanks to all for thr input, Clyde

If its only a spoonful of oil I wouldn't worry about it. When my seal was leaking there was a about a 1/2 ounce in the driveshaft tube and it was leaking on the garage floor as well.

Hi, There is supposed to be a little grease that goes on the gear in the wheel hub. They should do that when you get a tire changed, if they know what they are doing.

If what I think of as an egg cup is what it is.. This is a leak worthy of replacing the seals.. If you can remove the seals and they are still mint, you may clean them, and re-use them, but i have my doubts this can be done and still have mint seals.

I can tell you that i try and on ocasions I even can, save a drowned seal, but you can bet I have a new set of seals on hand..

I maintain the book is WRONG, and that book spec is too much oil in the case. Also that the book spec oil isn't enough oil at all in the first place for final drive gears.. That the every 2 years or 24,000 miles it total hog wash.

If the amount were more like 24 ounces to 32 ounces that 24,000 miles might be closer to correct.

I never measured the oil really so I don't really know, but my guess would be 5.5 ounces of oil is as good as 6.2, and then the seals won't get over run and over flow.

Once a good seal leaks oil it will never stop leaking oil... Capilary action sees to that effect... There are 2 fixes.. R&R the seal and clean it well, and get it dry, and the same for the seat it sits in, or install a new seal doing the same things...

All new and used seals should be filled with light all purpose grease on the install and the shaves they seal should also have a light film of the same grease assembly grease that more or less matches the type of oil used.

skyhookman. Yes there should be moly lube grease on both sets of hub spline to wheel splines.

Anyone changing a rear tire is either due for, or is over due for a swingarm service. The book calls for 7,000 miles at a wack. If you have never done one, don't be surprised to find NO grease in the long swingarm bolt, the 3 spacers inside and out, or in the bearings, on the ends of the swing arm...

Ma Kawii is some wicket stingy with any grease!

[skyhookman]

Did the swing yesterday. Did the zerk fitting pumped her up and now I have grease comeing out of all the right cracks. Every thing was loose enough to take grease without doeing any grinding.

[dogdoc]

gadgets page says you need to mill that inner swing arm tube for the grease to work its way all across. Good to hear yours worked. How was the install of the zerk??

[skyhookman]

The zerk was no problem, took a bit of grease until everything filled up, and then you could see the grease start to show up between the swing arm and the frame. I'll give it a little when I change the rear tires and that should take care of it.

skyhookman, would love to see some pictures of the zerk process. Havent ever done the swingarm myself, and would like to. If/when I do i will be wanting to add the zerk

[skyhookman]

you know, Ive never been able to post picture here for some reason. I've done what they all said to do right down to the tee, but for some reason they wont't take. I guess you noticed, I dont have any sig picts or my bike in the avature. Didn't have any prob in some other places. I just can't get them to stick here. Look in, Gadget fixit page, he has some real photos, I basically did what he showed, I had enough slack at the spacer that , I didn't need to grind the grooves. I just drilled a hole in the middle of the spacer, all the way through to the other side, I took it out first before I drilled it. Cleaned it up good put it back together and started pumping on the zerk. Finally it started ozeing out between the swing arm and the frame and I was full up. I'll greaser againt when I change the rear tire, probably in about 11-12000 miles.

thanks will look at the gadget page
