Swingarm Pivot Shaft Grease Fitting

[Yaxy]

Has anyone installed a grease fitting into there stock Banshee swingarm on the pivot section? I can't keep bearings and the shafts from rusting and seizing after 4 months. It appears that it will easy to do just where and how many should I put in. I feel the best would be in the center, but would it end up hittign the motor or shock?

I will try to post some pics in images. I just did mine.

I did the one on mine and my son's also. I tapped and installed a plug on one end of the swingarm bolt and the zerk in the other. I then drilled a hole in the middle of the bolt and lightly ground a "channel" around the bolt at the hole. I made a corresponding hole in the piviot tube that, when installed, lines up with the hole or channel that I made on the bolt. The pivot tube is hardened so you won't just drill a hole through it. I used a small grinding bit and a dremmel. Grease it a little at a time and it will make it's way to the bearings. IMHO, this should have been done by Yamaha along with a greaseable axle carrier. It's not hard to do and is well worth the time it takes.

I thought about doing it that way but I wasn't close to a welder to plug up the other end of the hole and the bolt on mine is hardened. I drilled out the swingarm. I have several good pics if someone wants to see how I did it and if someone wants to post 'em that's even better. I used an angle zirk that screws into a 1/4-28 threaded hole and used a small nylon washer under the zirk to make sure I could turn it where I wanted it. It took less than 1/2 hour to do. It would probably only take 15 minutes to do now that I know what's involved. Total cost: less than $1.

Great ideas guys. They all sound like they would do the trick. What if I drill an inch or two hole into the bolt on both ends and put grease fittings in both ends. I could then drill a hole in bolt ends an inch or two in where the bearings are. Thus the grease would have a minumim ways to travel and would go directly onto the bearings. I would probably to have to gind a groove or put three holes in the tube to make sure the greese would go into the bearigns when the greased???

Well if your bolt is like mine, you'll ruin a few drill bits before you realize that it won't drill. Send me an email and I'll show you how I did mine. Super fast only a couple tools and you don't do anything to the strength of the bolt.
