[R-390] New Project (PTO)

[Carole White-Connor]

Thank you, everyone, for your help. As always, your knowledge staggers me. More
than that, your willingness to help out shows just what a great group you are.

The problem is in the PTO linkage. The KC knob does not turn the PTO shaft.

In looking at the Oldham coupler, I have a stainless steel disc between the KC
knob drive and the PTO shaft. It has a groove that mates with a ridge on the KC
knob drive. There appears to be groove in the back that do not mate with the
PTO shaft. The stainless steel disc fits very loosely between the KC knob drive
and the PTO shaft. It's definitely more than the 1/32" gap shown in the Y2K
manual. There is no anti-backlash spring.

1. My first question is whether there should be one or two discs between those
drives. I'm looking at Pete Wokoun's diagram in the Y2K manual (Figure 6-4) and
it's a little hard to tell.

2. If there is only supposed to be one disc, why is everything so loose and why
doesn't the KC knob turn the PTO shaft? What's the fix?

3. I've never had to work on a PTO or Oldham coupler before so I need simple
instructions (very simple, might be more like it!).

4. When I turn the PTO shaft a little by hand, I receive stations loud and
clear, so I'm pretty sure the linkage is the problem.

As always, thanks.
