This 2016 Service Instruction introduces a plug to replace the zerk that is removed every year (one plug per side). https://hartzellprop.com/wp-content/uploads/HC-SL-61-354-R00-W.pdf Hartzell's 2018 price sheet lists them as $0.74 each. I've not tried to order them myself - I bought a couple from a local A&P who had ordered several. https://hartzellprop.com/wp-content/uploads/2018-Price-List-Orig.pdf -- Tim Lewis -- HEF (Manassas, VA) CFI, A&P RV-6A N47TD -- 1104 hrs - sold RV-10 N31TD -- 1200 hrs ________________________________ Message 2 _____________________________________ Time: 08:48:16 AM PST US From: Kelly McMullen Subject: Re: RV10-List: Hartzell service bulletin, plug to replace grease fitting Curious. I can't imagine why the zerks would seize, given they are threaded back into grease, except for the person doing the servicing using their calibrated elbow for a torque wrench. Never had a problem with the zerks in the 18 years I had a Hartzell prop. Also tend to believe that those zerks and plugs are standard FAA/PMA Autozone parts. Not sure why the plugs would be any less likely to seize, unless they are made of a metal compatible with the forged aluminum of the prop hub. Maybe I should do a little experimenting with a red tag Hartzell hub I use as a big paperweight.
