Wellgo pedal rebuild? Ideas?

Okay, before anyone gives me grief, I LIKE my cheap little SPD Wellgo pedals. They're what I need right now, and I'd like to be able to keep them for a while longer. I simply can't figure out how to remove the spindle and service the BBs on this guy. Please take a look and toss some new ideas at me. Thanks!

No end cap as is found on many models.


Shows model number RC-703

3 things to do. Keep the body screws tight, Keep the cleat jaws lubed and keep the bearings lubed. Andy

Your thumb in the second photo is beside what passes for a lock nut on those pedals. You will need to unscrew it to get at the spindle and bearings. You will need to brace the pedal to remove the nut. May not come apart easily. May not go back together easily. Good luck.

I believe you unscrew the grey part with the flats from the black body, and the whole bearing assembly should come out. On my Shimano PD-M520, it works that way, but they use a custom "reeding" instead of flats, and I had to buy their custom tool, a plastic disc with the same reeding plus flats for a wrench.

Is the pedal bearing actually loose? I have never actually found any of my pedals needing service - Shimano road, SPD or Speedplays. These are sealed pretty good. I take them apart, regrease and adjust the bearing, and they seem just like before.

Yeah, that *looks* like a lock nut but isn't. It's actually a plastic thing that collapses when you put a wrench on it.

Right I know itís plastic. To get the peddle spindle our that has to come off. Probably easier to squire new peddles. Best of luck.

That looks a lot like the Shimano pedals.

The grey part with the flats on it next to the black pedal body is what unscrews, and it takes quite a bit of unscrewing to pull the guts out of the pedal.

The outer grey sleeve is just a spacer. There is no lock nut.

You should find a sleeve with cones and bearings inside that should be relatively easy to disassemble, clean, and repack.

For Shimano, it unscrews normal (counterclockwise to loosen, clockwise to tighten), both sides.

For the Shimano pedals, the cheap plastic ones use a special multi-faucet tool. The more expensive ones use a titanium bolt, I think.

Anyways, on yours, would a deep 6 point socket fit? Either 16mm or 17mm? Or maybe a 6 point box-end wrench if it will fit over the top.

You can also purchase 6 point "flare nut" wrenches.

That is assuming you can get them slipped onto/off of the pedal.

For Shimano pedals, you use the Shimano TL-PD40 tool for this:



But every manufacturer seems to have their own proprietary tool for this purpose. I haven't seen a Wellgo version, but that doesn't mean there isn't one out there someplace.

If you ever manage to get it open and remove the spindle, the bearings will probably come out with it in a retainer...In which case, servicing is easy. Just fill the pedal opening (where the spindle fits) with grease, then thread the spindle (with bearings) back in and watch the old dirty grease be expelled from the pedal.

FWIW, I love Wellgo pedals. Although mine are MG-5 flats.

Some pedals are such a PITA to service it's tempting to just wear them out and buy new. I tell myself that every time I consider servicing my old Look clipless pedals. They seem to be okay so I'm just gonna leave 'em alone.

I just serviced a nice set of Wellgo aluminum platform pedals and everything was pretty easy other than the cone/bearing surface and separate lock nut. The only way to hold the cone in place while tightening the lock nut was to jam a thin but stiff bit of metal into the tiny space between the socket and pedal body. I think I used an old mismatched table knife because every other makeshift tool I tried bent. Took half a dozen tries with each pedal to get it right. And I'll still need to check the pedals every ride to be sure it's holding securely. The pedals are too nice to discard but without the appropriate tool to hold the cone in place it's a real chore.

Another reason I'm a fan of Stolen Brand Thermalite platform pedals. Cheap, good, just ride 'em 'til they wear out and buy another set.

In the case of the Wellgo clipless pedal above, I'd write or call Wellgo and ask 'em if the pedals are serviceable. Maybe they'll offer tips or point to the correct tool.
