Hartzell overhaul costs
 

What are some real world costs for hartzell 2 blade CS hub/prop overhaul costs? Please state prop model if possible.

A local shop here says $3000-3500 is typical. Sounds a little high to me.

Sounds about right to me
 

When I was at Hartzell this spring (Piqua, OH) they mentioned that same range and I think they wanted it every 2000 hours or six years (I think).

One of my friends just got his back from American Prop in Redding California.

It is the Hartzell used on the 200 HP IO-360 and uses the 7666 blades. He reported that it was just under $1,800.

yes every 6 years but...
 

Yes Hartzell recommends 6 years BUT here in Canada, COPA has lobbied the gov't to allow up to ten years (with inspections) then mandatory overhaul. The shop I spoke to said, they still recommend what the manufacturer recommends, 6 years. "Props that go the full 10 years are more often beyond corrosion/erosion limits". That's what he said. I don't understand how if it's maintained and checked regularily how it could all of a sudden get "beyond" limits on the tenth year. I don't know cause I've never owned one.

So best price so far is $1800.00 (I guess it depends on what needs to be replaced.) Thats $300/year for the operating budget. :(Sound right?

Shop around & OH cost depends on the model/age
 

Shop around but make sure you go to an approved Hartzell shop. Call Hartzell and tell them what shop you are thinking about going with. For legal reasons they don't publish bad shops but they can give you a wink and nod if you give them a choice of two or more shops. It does not do any good to pay cheap and get something less. Many AD's for Hartzell's historically are about overhauls at one shop or another. One example, the prop shop did not use the proper medium or process for stress relief (shot peen).

Hartzell has a list of approved shops/dealers, but these are not the only approved repair stations for Hartzells, just dealers. In fact some dealers didn't impress me or are not competitive price wise. I called about the eddy current inspection for the older Hartzell's. I called a Hartzell dealer did they not have the probe to do it? I also checked prices of the 100 hour inspection and they varied wildly from $100-$250.

I have bee told, been quoted $2000 to $4000. It also depends on if there is a bad part.

It really depends on the MODEL. Older F7666 blades and C2YK hubs like I have, need more inspections and work during overhaul, so it cost more at OH time. New designs are cheaper to overhaul. I agree the 6 year deal is short. I go by time. They have to account for a plane left outside on ocean coast 24/7, not flown regularly. Corrosion is a big killer of props. Moisture works into the bearings and causes corrosion pits. A pretty RV kept in the hanger, flown regularly is not going to have the same corrosion environment or risk. So some shops quote high and low. Shop around and tell them you can get it cheaper; ask them to match it.

A prop overhaul is really a tear down and very detailed inspection. They strip the blades, measure them clean them up and re-paint them. Old blades need more detailed inspections, pilot bearing removal / replacement and extra fatigue improvement, like a shot peen. The hub and bearings are inspected, but than they just put it together with new seals. If there is a bad part, it will of course be more expansive.

about 1800 for me
 

RV-6 0-360 with Vans recommened C/S, circa 1995. not sure what blade numbers. I had blade seal leaking grease. Prop was about 10 years old too.
We removed prop and met prop shops truck, they OH'ed and we met delivery truck, and reinstalled prop. Charges from Prop shop was about 1800.

The leaking seal MADE us have the prop serviced. We had been struggling with the decision on when to service the prop. Our plane was well cared for and always hangared. We have seen and heard of certified planes going 20 years or more without servicing, etc. But also hear or read stories when the prop just starts leaking without warning and we all want to do a good job of maintaining our planes so they are ready for a cross country at the drop of a hat, or any reason to fly. We spoke to Hartzel at Oshkosh and they told us what other have said above about the 6 year OH is mainly for corrision and some air carriers operating in the west (drier air I guess) had that extended with inspections to prove there operating enviroment proved to allow safe
operations beyond the 6 year time period.

So I would kinda vote for 10 year servicing........for a well cared for prop like ours.
Good Luck.

I bought used and OH CS prop
 

$3500.00 for the prop for my IO320. My friend paid the same for the prop for his RV10.

R&D Propeller
 

I just had mine overhauled at R&D Propeller in Pearland, in S Houston, TX. They did a great job, and even met me close to my home field after I got it back on for dynamic balancing on the way back from picking up some props for overhaul.

The cost for the overhaul was a little less than $2K, and they did a great job. I would recommend them highly. It came back like new.

This subject has been debated for a long time, when do i get my propeller overhauled or looked at?

The problem we see being in the propeller industry is that propellers are a very well designed pieice of equipment and will go along time with very little maintenance most times which leads people to be complacent with maintenance other than dressing rock nicks from blades.

There are many things that can occur from low maintenance or no maintnance, corrosion, seals cracking or getting hard, internal grease seperation or breakdown and metal fatigue.

We reccomend if you are not going to have it overhauled at the manufacturers reccomended time becuase of low hours or dry enviornments is to at least have the propeller resealed and safety checked at 6 years, this will replace all the seals that have been in the propeller for the last six years and to make sure that there is not a problem that is slowly wearing out a part and getting it fixed before it cost alot of money when you bring it in for overhaul, or fix something that will eventually lead to the propeller to stop working. The reseal is cheaper than a overhaul and can help offset a huge part cost when you decide to overhaul the propeller.

The comment by gmcjetpilot to try and get a shop to "match a price of a competitor" is a bad idea i believe, the problem is that if you do find someone to do that they may cut some corner to match that price, we have one price here and we stick to it because we do quality work and that price is what it takes to do that work and to pay quality technicians to do that work.

The final thing i have to say is to please maintian your propeller, the result of failure is not very good sometimes.

"one price"
 

Thanks for all the replies. I like the idea of "one price". It makes the estmate very accurate.

James, what is that "one price" for prop overhaul at your shop? Hartzell C2YR-1BF/F7497

What would the shipping cost be to 98226.

Thanks
