So I sprung for the swing arm needle bearing upgrade. Before I start putting everything back together, I pumped some grease into the pivot shaft to clean out the old goo and then it occured to me that the pivot tube that comes with the needle bearing upgrade kit does not have any grease holes in it. I assume that once assembled, the grease would go through the pivot shaft, then through the pivot tube to where the bearings are. Should I drill some holes?   Also, the (four bearings - two per side) bearings are not the same on both ends. Can anyone tell me which end goes towards the inside of the swing arm for the first bearing and which end goes towards the thrust washer for the second bearing? Instructions are in German...parts made in Japan... |

I don't know about the bearings but you might want to drill and tap a hole in your swing arm for a grease zerk to keep those bearings greased. Bottom center.

Thanks xsleo. It didn't even occur to me to put a fitting in the swingarm even though I remember reading about it somewhere now.

First650 what did you find out about the bearings? I am doing the same and wondering which end goes first?? Simple question enough. Thanks

Most bearings of that type insert with the numbered side out.
In the pic you see the bearings have a thick side and a thin side. To insert the bearings, if you have to use a tool for install, the thicker side out gives you more material to drive against.

Put the bearings into a deep freeze for several hours. Clean the inside of the swing arm where the bushings seat. When ready to seat bearings, heat the swing arm with a heat gun. When hot the bearings will slip right in. Seat the inside bearing with the numbers in. Drive this bearing all the way into the machined lip on the inside of the tube. Place the outside bearing numbers out. The outside bearing only needs to go in about 3/8 to 1/2 an inch. This will leave a space between the bearings. Measure from the outside in and this will give you the spot to drill for a grease access hole. I would drill 2 opposed from one another. As set the bearings will spread the load over a greater area, and the gap between will allow for lubrication. I also recommend dry assembly of all components and put onto the bike to allow you to get a feel for things. A first go with greasy components can be a real pain. Good luck.
