Just my opinion, but I think the metal gears are way over valued. I still think they were a cost
cutting measure when they ran out of nylon gears near the end of the production cycle. Nylon gears
themselves are inexpensive, but the tooling to manufacture them is quite expensive. If the tooling
'wears out or is lost or broken, metal gears from stock look a lot more attractive.
The metal gears have a 'grainy' feeling to me, while the nylon ones are smooth
as glass.
When the nylon gears are 'soaked' in oil, it sometimes becomes necessary to re-do the 'Smooth as
Glass' process on 'hfn after they have swollen a bit more.
Opinions are like ... well, you know.

Rich,
Based on my experience...clean those gears with soap & water & use a stiff brush to be sure NO old
gread, dirt etc is in the very bottem of the teeth.
Maybe you have already done this...if so maybe there is still oil in the
plastic?

Subject: [Drakelist] R4C PTO Brass Gears replacement
Ive had my R4C PTO rebuilt about 8 months ago and the PTO tuning felt
great. Before the rebuild it would stick and would have different
tightness as I tuned.
I hadn't used the rig for a few months and turned it on last night and I
have the same issue again. Wanted to know if anyone changed out the
nylon gears for the brass set? I think the nylon gears keep swelling on
me. And yes, the oil was removed during the first rebuild.
Also...does anyone have a set of brass gears or an old broke PTO with a
set of brass gears on it that they would like to sell.
