What it is
RJ The Bike Guy walks through taking a threaded bicycle freewheel apart, cleaning and greasing the parts, and putting it back together. He uses a pin spanner and chain whip, reuses the original 1/8 inch ball bearings, and explains why someone might overhaul a freewheel instead of replacing it.

Fastace [LINK] is a maker of bicycle components. That looks like a freewheel with one belt drive sprocket instead of 5 or more chain drive sprockets. See the Terminology Index [LINK] for a description of the difference between freewheel and freehub/cassette systems. The belt drive freewheel should be removable with a four tooth removal tool (see the Park Tool video below for tool selection guidance). You'll then need to get inside the freehub to clean and re-lube the bearings and racheting mechanism. I believe that's done using a pin spanner to unscrew the rings with 'KENGMIN fastace' written on it. See the RJ the Bike Guy video below for a idea how the might be accomplished - your freewheel

I have watched videos for Bicycle Freewheel Disassembly/Assembly, and disassembled my damaged bicycle. The back wheel of it started to Cranking, and by opening its part based of this [this video] video instruction: [LINK] I have bought one ball bearing for it, but it seems not fit in its hole as you can see: [LINK] Also you can see below that,there is some corrupted part inside the hole which I guess there must be something inside it like which I understand it is broken and detached to two part as you can see below: [LINK] So, if possible, I want to know how can I replace bearing cup( sample photo of cup, but not my case [LINK] !)? Maybe by removing the bearing cup of other side or something else

I have a Maillard freewheel, big cog stamped 10 - 84, which i have taken apart, cleaned, lubed, and reassembled following the excellent youtube by RJ the bike guy . i don't know for certain, but i may have "misplaced" the spacers which slide down the body and allow the pin spanner locknut from crushing the bearings. the freewheel is back together, but i cannot tighten the locknut and still have the cogs rotate. Q; how far up the river am i, and what can i do to get new spacers/ what size? thanks
