Does anyone know how to remove the cogs from a circa 1974 5 spd Maeda Industries Ltd. Pro-Compe 5
spd freewheel. I would like to change a cog. I did it last time over 25 yrs ago and forgot how.
(senility?)
P.S. no, I have not been riding it for 28 yrs, its still in good shape and worth using even if I
can't change out the cog.

Thanks Jeff

The smallest freewheel cogs tend to be threaded on, and because of that they will be very hard to
remove, since they tighten with use -- and 28 years of sitting around will not make this easier. The
larger cogs are probably splined and fit on specific parts of the freewheel body.

Get 2 chain whips, put one on the smallest cog to try to loosen it, and put the other on the biggest
to hold the freewheel.

If you don't already have replacement cogs, you may be out of luck. I don't think you will find cogs
for that freewheel for sale anywhere.

They are similar to Suntour Winners in that the last two cogs secure the lower gear splined ones.
Hold the low gear in a cog vise. Uncrew the high gear with a chain-on-a-stick tool. Unscrew the
second highest cog the same way. Now you can slip everything else off with your fingers.

All the cogs and spacers for that system are readily available up to 38t!
