Help with Freewheel Maintenance - Page 2

30wt oil would be good to lube a freewheel. Just add some once in a while. I've also used 90wt gear oil with sucess, and this might overcome any thinning from residual WD40.

What's the difference between a freewheel and a freehub?

And also, I wiped down all my cogs, and they're really clean now. Do I have to grease them up before I put the chain back on?

Grease is for internal bearings only. Lube the chain with good quality oil or purpose made chain lube. (Some chain lubes are wax based, do not let this sort get inside the freewheel/freehub, it'll clog it up. I know this from experience; I wasn't always old and wise.)

Freewheel threads on to the hub. It can be a cluster of anything up to 7 gears.

Freehubs are a part of the hub. They consist of a solid body, sprung pawls (2-6. 3 is the standard) and a drive ring in the hub, or in shimano's case, part of a thread on body, which doesn't come on their Dura Ace hub cause its just better. They are splined and allow the cogs to slide on and off, kept on by a lockring meant to be torqued to a ridiculous 40nm, which no-one I know does.

Freehubs are plain better.
