Swingarm grease nipples

7 posts in this topic

I just finished replacing all the swingarm and link bearings(00 426)over the last few days and aside from water contamination the bearings could have lasted alot more than seven years. Without to much trouble I managed to install grease nipples to get grease to every bearing in the assembly. The hardest part was drillling the hardened races in the swingarm. One carbide drill later and it was done. Then I figured the grease would push the seals out so I installed O-rings between every seal and whatever housing the item was assembled in. Just thought I'd post this up because it can be done with little effort. Just a few taps and drills really. The carbide bit can be bought in any industrial supply store and you only need to drill two holes. I even threw a grease nipple on the rear brake pivot.

I dont think I, personally would do the swingarm mod, but I love the rear brake nipple. One of the most neglected parts on a bike. PS. very clean 426

My last bike was an 96 KX500. As such I've been really into it and have gone over just about every nut and bolt on it.

The Corrado was last winters project. I bought the car with a 1.8T in it and it blew up on my first day out. #3 rod and various parts were spat all over the BMW behind me. Aparently VW's don't like BMW's. Bad engine management setup and really shoddy engine swap will do that. Now it has all the goodies and about 350hp. Unfortunately she's been put away for the winter.

Hehe I did the rear brake as an afterthought. Figured what the hell why not.

IMHO the linkage is the most important because it is subject to so much dirt and crud. When I pulled them apart they were rusted right through and the needles fell out with the races.

Next time you have to drill through something tough, try cobalt bits. Best thing I've used yet for drilling hard metals.

nowhere neaw as good as a solid carbide drill though a bit more expensive. When I was a toolmaker we used masonary drills that we sharpened to drill through hardened D2. We'd put the machine in low speed with no coolant and drill through quite easily. However these were just holes for putting the wire edm through and they didn't have to be accurate
