Default PCU 5000X prop governor & IO-390

All,

I will be ordering my FWF kit soon. Has anyone used the PCU 5000X prop governor on the IO-390? Any problems mounting this governor? Any problems with the stock bracket and the prop control in the FWF kit.? Any information would be very helpful. Also will be using the Hartzel blended aluminum prop from Vans.

Thank you,

Default works great...

The PCU 5000 can run from the back or front of the case and needs to be geared correctly for the choice... also, the direction of rotation can be CW or CCW. It can be changed from one to the other but you will have to send it back.

I suspect that the 14 has the routing worked out so you just need to order the right rotation and mount location.

Rather than starting a new thread, I'll just resurrect this one...

It's time to order the prop governor for my RV-14 build. I'm going to take advantage of the advertiser special that was listed on the Front Page of VAF a few days ago - 15% off the price of the PCU5000X!

I need some specs, and the guys at Aero Tech can't answer for me. I'm putting the standard IO-390 with the Hartzell 74" prop on my plane. So...

1) Gov drive ratio - I'm assuming 947:1 based on Lyc IO-390 wide deck fwd mount.

2) Control lever rotation - clockwise or counterclockwise???

3) Oil Pressure to Increase Pitch or Decrease Pitch???

4) Take off RPM ???

If you've got similar setup, what were the specs on your governor?

Can the sales rep look up the specs from a previous customer?

I have the PCU5000X on my RV14 with an IO-390 and the Hartzell blended airfoil prop. I’m not home to look up the info but I will PM you my name and address for him to see which one I purchased. I will say it was very difficult to order because they sent a spec sheet that was impossible for me to understand and a few of them really did not understand it either. Also, I had to replace the pitch stop screw because the one that came on the unit did not work with the -14 cable system. If you purchase it I can send pictures of the linkage. If I had it to do over again I would just purchase the one Vans sells and it would fit straight away.

I ordered the Hartzell governor, Hartzell prop - easy way to go IMHO. Both fit the standard kit/engine well, no muss no fuss...

Marvin,
What is the lowest RPM your governor operates at the coarsest setting. I have the Hartzell governor and not very happy as it goes down to 1700 RPM when it is pulled all the way. Hartzell tech has confirmed that this is normal for this model governor.

This is being corrected to prevent others mistakes
.895:1
Counter clockwise for the RV-14
Oil pressure to increase pitch
2700 takeoff rpm

At least that’s how mine will be spec’d

Anyone got the specs worked out for the IO-540 C4B5? I'd like to get in on this and it's time to move on it.

And by the way, Brad - I'll take a couple of those 6-cylinder P-mags any day now, pal

I believe the 0.866:1 is for a rear mounted governor. I think the front governor is 0.895:1. At least that is my understanding from Lycoming and Hartzell for my composite prop using an S-1-79 governor.

You might want to double check this to be sure... the drive ratio depends on where it is mounted on the case and the rotation of the arm and RPM change is routing and description dependent.

Mine is forward mounted with the control arm over the top of the cylinders... push for high rpm (cw from HRRPM to LRPM)
947:1
Pressure to increase
2700 rpm take off
