Well I finally after almost owning my bike for three years decided to do this mod.
The zerks were still there. The back one was messed up the most, the front was fine, filled that one up.
Went to the middle one and this happened.
Guess the ball was gone.
So I figured it would be fine til I got a good zerk in. But when I went to do the back one it wouldn't even take grease, actually the hose jammed up and I had a bubble in it about the size of a quarter.
4500 psi working pressure? Guess I am ripped.
Anyhow so I removed that rear zerk which threaded out fine, but I had a hell of a time getting the good one in. Oddly enough the old one would go in very easily. I was really careful not to strip it out. But once I did get it in, the grease wouldn't go in but it started to seep out around the base of the hex portion.
So I figure I will have to up size the the zerk. But I am worried that the taps that I do have will be a problem. They have pointed tips and the threads don't start out till probably too late. I am thinking that the tap would hit the through bolt on the knuckle. I had seen someone on this thread mention something about a bottoming tap
. Is that a different type of tap? I haven't tried any of the new zerks out, but maybe they will work better and I won't have to tap.
I don't know why but it only seems the a few people have mentioned using a Grub Screw
. That seems like they would be better then a cap screw since it would be flush. Also has anybody thought of trying to find an all nylon screw that way it wouldn't strip out the aluminium casting? Which they do make in a grub screw style.
edit: Found out what a bottoming tap is. Good ol' wikipedia. Found a whole article about taps. Tap and Die
If I got one of these maybe I could just chase the threads.
