Some of the same bolts that hold your cylinders to your Lycoming engine also hold the case halves together. When removing a cylinder, or especially if more than one cylinder is removed, it is very important to maintain the torque between the case halves. The worst case scenario is that you’ve removed a cylinder, or more than one, and then inadvertently bump the prop, which is very easily done. Bumping the prop when the case halves are not 100% torqued together can potentially cause movement of a crankshaft bearing, which can lead to engine failure later.

Installing our cylinder torque plates is an easy, inexpensive way to alleviate this concern.

Nicking a connecting rod is also a potential cause of engine failure. The thick center grommet will prevent connecting rod damage by giving it a nice, safe rubber pad to rest on. This product is a direct replacement of Lycoming PN ST-222, and is compatible with all Lycoming engines except the 0-235 series.

Lycoming and other sources want a ridiculous price for these simple devices. Save your money and get them from Flyboy Accessories at a very reasonable price!

These are nice hold-down plates. Great price!

The only issue is with the the rough texture on one side of the plates around the holes. It appears there was no attempt to chamfer or de-burr the edge on one side, leaving a bit of slag on the edge from plasma cutter (?) If you installed the plates with that side against the case it would cause expensive damage to that engine case, which left un-repaired, would cause case failure. I would change the manufacturing process to address this. Unknowing users may cause flight safety issues.
