Glen Davis Posted October 23, 2020 Report Posted October 23, 2020 Is shimming a sagging prop covered in the service manual. Quote
ragedracer1977 Posted October 23, 2020 Report Posted October 23, 2020 (edited) Yes, but you shim the engine, not the prop. Edited October 23, 2020 by ragedracer1977 1 Quote
PT20J Posted October 23, 2020 Report Posted October 23, 2020 Don Maxwell has a procedure on his website. But before shimming, make sure the motor mounts don’t need replacing. Also, most J’s look like the spinner is out of alignment with the cowling because the play in the camlocs allows air pressure to push the top of the cowling up and back slightly during flight. The cowling may look perfectly aligned after removing top and bottom parts and putting it back on and then look out of alignment after a flight. Compare yours with others in pictures and on the ramp. I believe @jetdriven wrote about mods he made to his cowl to fix this. Skip 1 Quote
carusoam Posted October 24, 2020 Report Posted October 24, 2020 If it’s really bad... check on all the welds of the motor mount itself... If the rubber donuts are ancient you might want to get new ones prior to shimming... Then look up the fancy shim stock that has a slot to allow them to be installed without too much effort.... PP thoughts only, not a mechanic... Best regards, -a- Quote
Rjfanjet Posted January 7, 2021 Report Posted January 7, 2021 34 year old motor mounts. Needed to be replaced about 25 years ago. Quote

How does that work? Reason for question is that Barry states single part no. 94011-02 is needed for install per location. I like the price as it's much cheaper then (two) Lords. Quote
carusoam Posted January 7, 2021 Report Posted January 7, 2021 Lord vs. Barry... Ford vs. Chevy... Some people prefer Lord... When it comes to the big donuts... we only have Lord... I have the good Lords supporting my IO550... Best regards, -a- Quote
Robert C. Posted February 4, 2021 Report Posted February 4, 2021 Anyone know if you can buy just the rubber pucks for the Lord mounts (IO-550)? Don't see that on their website or Spruce's but figured it would be a lot cheaper than the $500x4 that I'm now looking at Robert Quote

carusoam Posted February 5, 2021 Report Posted February 5, 2021 Keep both eyes open when ordering the Lords... For the IO550...There are three of one type and one of the other... If you ask them why, remember to post the answer around here somewhere... https://www.lord.com/products-and-solutions/vibration-and-motion-control/aerospace-and-defense/fixed-wing/general-aviation-mounts -a- Quote
