Vic, thank you so much for posting the pictures of the PCU and giving the part number, I have been getting the go around tracking that down from direct communication with PCU. I did want to confirm you have the IO-540 D4A5 in your latest 10?
Also, did you note/order a lever offset (in degrees) or did you just do that at install, I know for my 7 I had to move it a bit from how it arrived from the factory, so really not an issue.
Cheers & thanks again for the info. Mike

Yes, I have a D4A5. And it was not clocked properly, but I think it might have been because they rushed it out the door after they initially shipped the wrong one. It is easy to clock---just take off the safety wire, loosen the 6 screws and rotate it to the position you want, retighten and safety wire.

Hi Vic, I would like to purchase your PCU5000X if Jack M. is unable.

Thanks, Bill 9364436846

Sorry---Jack jumped on it right away.

I installed Vic's and am back flying. My plan is to reinstall ours after the sb is done. Therefore, if anyone would like to loan Vic's, we would be happy to send to you. Mt is stating two week turn time at this point in their schedule

Has anyone verified if the flyweight design in the PCU5000X is the same as the Hartzell or the MT? From what I've heard elsewhere, the Hartzell uses a one-piece machined part, but MT used a 2 weld system on the ones that are bad, and a single weld (I hope I'm getting this right) weld on the new ones they are putting in. The question is, what does PCU5000X use? If it's a single machined part like Hartzell I'd be optimistic about either of those 2 options. I also am curious as to what my pre-2008 (mine is probably 2004-2005) P-860-3 has for a design. It sounds like they must have went to the weaker weld system somewhere around that 2010 mark. Not sure why they would have done that. But I'd be interested from a design perspective how my old one compares to the Hartzell and how the PCU5000x compares also. Right now I'm not too worried about my old P-860-3, but considering I have over 1200 hours on it, maybe I'd be interested in buying a new one and having this one overhauled. It all depends on the designs involved.

When I spoke at length to Sean regarding the PCU-5000X he assured me that the desings were completely different. We didn't know it was a weld issue at the time, so perhaps Sean will chime in here.

I just replaced the MT P860-4 with a PCU5000X (RV-8 equipped with an IO-360). The MT PG was due to go back for the 72 month rebuild.

I spoke to Sean (APS) at length about the PCU vs MT design. He answered all my questions and provided a lot more info I didn't know.

Sean indicated they are considering a change to the PCU5000X. I believe he said they are looking at putting lighter weight flyweight assemblies in them.

The PCU5000X I received need to be re-clocked, after that it bolted right on. The RPM was set correctly and required no additional adjustments.

To me the response of the PCU seems more linear and slightly less abrupt then the MT.

Not RV-10 related. Sorry for the thread drift.

The pictures poste by Vic shows that the MT and PCU-5000X governors are similar in shape and size, easily interchanged without need to change the control cable mount.
Is this also true for the Hartzell S-1-26 governor?
Does "clocking" refer to the positioning of the control arm of the governor? Meaning removing the 6 screws and turn the orientation of the control arm to fit your installation.
Thanks.
