I proceeded on the first winder, stripped, clean, and lubricate
the motor sleeve bearings with Polydimethylsiloxane, followed
by using Molykote ATM grease on all the cogs, both in on the
flat surfaces and on the teeth themselves. Then reassembled
that winder, and tested on a OM2n, I installed the the uncleaned
winder first, the put the cleaned and lubed winder on
Wow !!!
Smooth, the motor whine was a lot higher pitched, at least twice
the pitch, faster winding, and smooth, and smooth, did I mention
it was smooth ?
Ian,
Just out of curiosity, what is the low temperature rating for these greases
if you happen to have this data? Of interest is the low temperature at
which the grease would stiffen to a point of impeding the winder. Some of
us use our gear in severe cold weather; I've been out in -20F on a couple
of occasions. Rarely that cold here, but it does occur, and I know the
Canadian and Scandanavian list members can easily experience those
temperatures and lower during Winter.
