Hi Rich,
I agree with you that the metalNylon assemblies seem to have a smoother
feeling with less sloppiness. I don't know if the all-Nylon gears degrade
over time or if they came that way from Drake.
I changed a set to metal/Nylon gears back last spring. I was first going to
attempt a change of gears, but I decided to simply swap out entire PTO
assemblies from a late C line that was in less than average cosmetic
condition. That's a very easy job. Just a few wires are unsoldered, three
screws removed, and the whole PTO assembly with dials comes out. No
calibration, no worry about gears meshing and tracking properly, etc. After
changing out one assembly and learning from it, another can be done in just
a couple minutes.

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.
Thanks...
Rich
