Cylinder Torque Plate for Lycoming Engines

Material note: We have been changing the materials and finish options on this product to keep costs as low as possible for our customers. At the moment, we have a mix of different finishes in stock and you may receive what we have (there are options that are red or grey painted steel, and a newer version that is uncoated stainless steel, as seen in the main product photo). We'll try to match any sets that are ordered together, but can't guarantee that you'll get something exactly like the product photos! 

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!
