Do any of you, especially the classic/vintage guys use one of these? Is this a good way to go for freewheel maintenance?
Thanks,

It works pretty good and is far easier than taking a freewheel apart for service. two hundred tiny bearings all loose :eek:

Every freewheel body I've ever owned needed oil, not grease. Most good freewheel bodies have an oil port, someplace under the cogs. I've never needed more than an oil dropper to lubricate a freewheel.

Yup, oil is the best. I flush out the existing oil with solvent, air dry, and add oil. Just to make sure the oil gets in thoroughly, I blast some air in afterwards.

what they said.
As RevChuck hinted at taking a freewheel apart can
be a challenge, especially chasing ball bearings (78) around
the shop floor. One site I've frequented suggests soaking
the entire freewheel in solvent, and then oiling it.
If you do take it apart, grease only the races for the ball bearings,
don't grease pawls as this will gum up and cause all sorts of
problems.

I flush it out with WD40, form the large cog side, then drizzel std bike oil in.
Some better freewheels like Sachs are sealed for life and dont take kindly to solvents.
