Prop Shop Recommendation
 

I have a hartzell constant speed with 500 hours on it. Nothing wrong with it, but I would like to get it to a shop for IRAN. Any recommendation would be great.

I?ve heard from good friends that they have been happy with Tiffin Aire out of Tiffin Ohio. I had a tour of their shop and it was well equipped, clean, and very organized. The shop is right at the airport 16G.

Plus one for Tiffin Aire.

Hartzell Propellor Service
 

I used Aircraft Propellor Service in the Chicago area. They were next to PWK at that time but I see they are now in Lake Zurich. They also had a pickup and delivery service which I found out about after I drove my prop down to them, however they did deliver it back to my hangar. Not sure if the delivery service goes as far as Racine.

plus 2 for Tiffin Aire.
Honest, reliable, good service

Why? Do you suspect something? Is it spitting grease (a little is normal). I would not spend the money unless it needs repair. All the best. Remove both grease one of the grease fittings and punp out all the old grease and put the fitting back.

I had a good experience with New England Propeller Service, 3 Matthews Dr, East Haddam, CT. Included a visit to their shop which seemed very professional and capable. I'd go back to them again.

Preventive maintenance
 

I don't suspect anything. The prop has 500 hours on it and it's probably never been off since it was installed new back in 2004 so I think it's prudent to have it inspected.

Vic Syracuse went over this in his webinar Wednesday as well.

No, you don't want to do that with the Hartzell's. From the Hartzell Propeller Owner's Manual, page 6-9:

"(7) A label (Hartzell Propeller Inc. P/N A-3494) is normally applied to the propeller to indicate the type of grease previously used. Refer to Figure 6-3.

(a) This grease type should be used during relubrication unless the propeller has been disassembled and the old grease removed.

(b) It is not possible to purge old grease through lubrication fittings.

(c) To completely replace one grease with another, the propeller must be disassembled in accordance with the applicable overhaul manual.

CAUTION 1: OVER-LUBRICATING AN ALUMINUM HUB PROPELLER MAY CAUSE THE GREASE TO ENTER THE HUB CAVITY, LEADING TO EXCESSIVE VIBRATION AND/OR SLUGGISH OPERATION. THE PROPELLER MUST THEN BE DISASSEMBLED TO REMOVE THIS GREASE.

...

CAUTION 4: DO NOT ATTEMPT TO PUMP MORE THAN 1 FL. OZ. (30 ML) OF GREASE INTO THE LUBRICATION FITTING. USING MORE THAN 1 FL. OZ. (30 ML) OF GREASE COULD RESULT IN OVER SERVICING OF THE PROPELLER."

Whatever prop shop you decide on to do your IRAN would be kind enough to report back to VAF regarding your experience. I truly value others advice and experiences in my decision making.
Thanks
