This front bearing cap gasket is an OEM replacement that is designed to be used in select outdoor lawn and garden equipment. The gasket is responsible for providing a tight seal for the front bearing cap, which helps keep the engine running properly. Over time, this part can wear and become cracked, which could eventually require a replacement. Gaskets are typically a part of routine maintenance and should be inspected regularly as they can become dry and brittle with age. Replacing a damaged gasket will resolve the issue and provide the seal that the engine needs to run properly. This OEM part is made of a durable composite material and manufactured to exact standards. It can be used in select tillers from Troy-Bilt and offers an exact fit replacement for compatible models. The part is sold individually and does not include additional parts or hardware. It is a good idea to replace all gaskets at the same time for congruity in wear. The gaskets are durable, but thin, so care should be used whenever they are being replaced. Always allow the engine to cool completely and disconnect power for safety.
