So I have a bunch of these pedals sitting in my stash. The PD-6400 and PD-7400 are the "triangle" shape pedals with toe clips. The 6401 and 7401 are the look compatible clipless pedals.
My wife has been using some PD-6207 on one of her bikes, and I have been using some 7401 in my attempt to learn clipless.
Some of the pedals in my stash are pretty rough in the bearings. Previously I was able to rebuild a pair of 6207's easily enough. You just pop off the dustcap and it was pretty straightforward. Here is the velobase entry for the 6207-- you can see the dustcap. The hardest part of the rebuild was getting the dustcap off.
But these others don't appear to be so simple. The 6400's don't have a dustcap. And the spindle appears to only be fastened on one end. I am not sure how they work. Again, here is the velobase for them:
Finally, the 7400 are like the 6400, but also appear to take a special wrench.
The PD-7401 and PD-6401 appear to be constructed just like the 7400 and 6400.
So my questions-- how does one go about rebuilding these pedals? And I note that Velobase says that some of them take "needle bearings"? Do bike shops carry needle bearings? Do all of them use needle bearings? And where to get the tool for the dura ace?
I guess I don't really need the tool just yet, because it is really the 6400 pedals that need the rebuild.
Finally-- should I keep the 6207's? Is this one of those "the old ways were best" or is it easy enough to rebuild the 6400 and 7400 pedals once you know what you are doing?
