Engine Mount Shim

Yaw Adjustment Test Shim for a Jabiru 3300 engine mount. To install a Washer or Spacer or Shim, you have to pull the engine off the mount. This washer will allow you to just loosen the engine mount shock absorbers, slide two of these washers in on the firewall side next to the rubber, and click them together in place. Then re-tighten the bolts and nuts to snug..(Do Not Torque per Jabiru Engine Installation Manual.) Pressure from the mount will keep them together. This was designed as a quick way to test if you need to remove the Yaw caused by your Engine. First check, if Power off glide centers your ball, if so, you might need to try this as a test. Install on the side that the Ball is on...( or the Foot that gets tired... LOL )

Print using a Higher Temp material such as NylonCF if you want to EXPERIMENT with leaving this in. This should give an Idea on how much spacer you might need.
