Vernier Prop Control

[George]

Our vernier control vibrates to high RPM..Is this an easy fix or will it require a new control?

Thanks

Some verniers have a friction lock that adjusts friction on the mechanism.  If yours does, turn the lock about a quarter turn and you should be able to "tighten" the control.

Unfortunately this control does not have the friction lock....I have been resting my hand on the control to keep the knob from vibrating to high rpm..

How old is it?  If it is original, it may be a good excuse to change it out anyway.  It is recommended that they be changed with each engine overhaul, but this does not seem to happen in practice.

Have you had the prop dynamically balanced? Vibration causes stuff to wear and get loose in the engine compartment, the panel, all over. 

[George]

Controls looks to be original and don't recall any mention of replacement in the logs. Prop was overhauled 2006 and has accumulated 500 hour since... no balance mentioned in the prop logs. I would like some new vernier controls especially for the mixture..

There are several threads here re replacing control cables. McFarlane makes the throttle, prop, and mixture controls and their website makes is pretty easy to acquire an "owner manufactured part" and the log entry info. You should discuss this with your A&P who will need to sign off on the installation.

Some people leave a rubber band on it and once setup in cruise, we wrap it around the knob and something else to keep it from turning.

The McFarland ones are over priced in my opinion. You can order one from ACS, they are based out of Lake Havasu City AZ. You have to order it through Aircraft Spruce. They did mine last year. You send them your original one and they build it to that spec and your mechanic can sign it off as owner produced part. It's half the cost and works fine.... maybe even less then half, can't remember.

Ask an experienced A&P.

I replaced 3 ACS cables with McFarlane. The ACSs were less than 20 years old and clearly inferior to the McFarlane though probably "good enough" if you're selling the plane soon. 

I did not price ACS after researching the difference. The McFarland throttle cable was under $300., the other 2 were a little more than that - prop and mixture are vernier.

Agree 100%... I've used McFarland and the quality is a bit better.

George (Hank?), where are you in NC? (FAA is still showing PFLUGERVILLE TX for N7164U.)

There's now a MSC in NC @ KMRN. Lynn Mace does a lot of Mooney annuals. Very experienced and reasonable rates.

Bob   -   I'm in Monroe EQY....That's great with a MSC in MRN...Was not sure where to go for annual....I need to head up your way and say hello to the both of you! I try and do as much maintenance as I can with the assistance of friend / A&P. Replaced some leaking valve cover gaskets and tires today. My right wheel has some small cracks...two on left half and one on right half less than 1/2" long and crack width maybe paper thick/wide. What might one suggest for finding new wheel assembly?

Talk to Lynn, I'm sure he can get you what you need re wheel. As I recall, Mooney wheels are generic, probably Cleveland? But he can tell you if it need to be replaced.

Do come see us! I'm out at the airport this week, doing my annual and adding an external power receptacle.

Please don't confuse George "Hank" with his C in NC with George "Hank" with his C in AL. I'm also trying to keep us straight . . .

George, are you new to the area?  Talk to DrBill, he's a local mooney owner and might have some tips of where to pick things up that you don't need a MSC for.

Sadly, Bill is selling or has sold his Mooney though O don't think he's completely withdrawn from MS. But the MSC I referred him to will treat George and anyone else in out area right.

George Hank:

Lynn tells me you scheduled an annual for February @ AGL and that he was able to give you a lead on where to get a rebuilt wheel at a fair price.

Ain't MonneySpace grand!

Yes...may have found one...Dallas Air salvage is going to clean it up and do some testing to check for cracks..hopefully on the way tomorrow if all goes well.
