AC43.13 page 7-7 para 7-40 (d) "Add the friction drag torque to the desired torque....". My 2 cents -----Original Message----- From: owner-rv9-list-server@matronics.com [mailto:owner-rv9-list-server@matronics.com] On Behalf Of Boyd Butler Subject: Re: RV9-List: Re: torque wrench calibration --> RV9-List message posted by: "Boyd Butler" The torque on the wood prop was to give the correct amount of crush on the wood at that torque not to have that added to it.Consult the correct torque tables, they will give it to you and don't just add to things because one thinks that is right as that could over torque the bolt. There are specific torque's for certain grade of bolt or for certain parts never exceed those values. -------Original Message------- From: Richard Scott Subject: RV9-List: Re: torque wrench calibration --> RV9-List message posted by: Richard Scott OK, so you got your wrench calibrated within a gnats eyelash. Are you actually measuring the torque correctly? First, measure the drag the nut / bolt combination exerts. Those nuts with the inserts will give you a few inch pounds. And the wood on my wood prop initially gave several pounds. Then add the drag to the specified torque and use that number for your torque setting.

I bought it for an rv9 but I know it will fit some other rvs. engine package heater package EIS monitor no fuel sensors fuel valve Oeitiker kit 1 metal tank and 2 gallons of antifreeze engine manual Will sell for $15,500.00 about what I have invested with no markup email me if interested at _carlrayw@aol.com_ (mailto:carlrayw@aol.com) It has been stored in a heated garage and is still in the crate. I have used a wrench to turn it over occasionally so I know it is still ok. Was going to start it up but decided it would be better not to unless I don't sell it, then I will have to run it occasionally till I sell it. Reason for selling is that I don't think I will get to finish and fly my kit for a lot more years if ever so rather than have it sit for much longer I would like to see someone get use of it. A hard decision to make but something I must do. I would like to have someone pick it up or I could deliver it for a shipping charge. I live in Michigan at Traverse City.

Measured as high as 3 ft. lbs. The spec called for 17 ft. lbs (I don't remember the inch lb. numbers), so without adding the friction drag amount I would only have gotten 14 ft. lbs, short of the spec by 17%.
