Freewheel not engaging - removal required?

[rmwesley]

Please could I ask your advice... I have a BMX wheel which is probably 80s / 90s. The freewheel (freehub?) doesn't consistently engage when pedaling, so I'm guessing grease has gunged up the ratchets inside the body and the pawls aren't able to engage. Does this sound likely and, if so, is it possible to pull the freewheel apart to degrease it etc? I also don't have the correct tool to remove the freewheel, so if anyone could also point me towards what tooling is required, it would be much appreciated.

Thanks in advance, Richard

Well, I've answered one of my own questions? Flushed it through with solvent and the pawls are now engaging much better / properly.

Still wouldn't mind knowing what tool was required to remove the freewheel though if anyone knows that.

Cheers.
