Rat trap pedal from a 1982 Motobecane. My assumption is this isn't designed to be user-servicable?

It looks like it may just pop in to the pedal. What I would try is a knife blade in between the cap and body and give it a tap like you're opening a watch case.

"My assumption is this isn't designed to be user-servicable?" doesn't mean you can't try.try prying where the taper ends,could be a interference fit.

IIRC these pedals have their end cap pressed on. A fine edged tool might pry the cap up a bit and then a slotted screw driver could do the rest. I suspect you'll find the bearings are common cup and cone and can be taken apart for servicing. The usual challenge is on reassembly and how to trap the cone from turning while the lock nut is tightened down. I would consider a non take apart flushing with solvent then injecting with grease. It's easy to drill a tiny hole (in the cap) and use a needle tip on a grease gun. Andy.

You may be able to pry the cap off with a fine blade but you will likely find a cup and cone bearing assembly with the end of the pedal axle peened over to hold the cone in adjustment instead of a lock nut. Good luck with this.

Thanks for the info, gents!
I tried prying it apart with a box cutter blade and I could tell the blade was going to fail before prying it open. I'll try again (carefully) with something a little more resilient. Sometimes leaving it alone is the best move.

If you do manage to get the dust cap off and discover that the spindle is peaned over making the bearings non-removable, you might be able to lubricate them with a very heavy oil or with a light oil mixed with some grease. I put the mixture into a syringe (from the surplus store near me) and inject the oil/grease mixture into the pedals.

You can get grease in there like you do a bearing, put the grease around the seam and push it in with your fingers...I have put an abundance grease on the seam and hit it with a quick pulse of compressed air...seems to work.

I've wondered if any types of grease will melt at low heat, so they can be poured into tight spaces, then re-harden back to grease when they cool down.

On non serviceable things like this (or don't feel Iike taking apart) I use these type of products. Sprays in as a liquid and sets up as a grease.

There's a lot of products that are aerosols that deliver grease in a volatile solvent, which achieves similar things to trying to melt grease with high temperature and is not so cumbersome. Spray these products into the bearing as a psuedo liquid, and the solvent evaporates off. I'd probably want something with moly disulfide in it. So in addition to dedhed's suggestions, here's another

The downside to the product I suggest is that its expensive. So dedhed's suggestions may be better (cheaper, just as serviceable).
