Parts for Briggs & Stratton 12C702-1708-E1: Crankshaft, Sump Base, Cam Parts

This genuine replacement crankcase gasket creates an airtight seal on the crankcase so that oil and air do not leak out of the engine when it is running. Over time, this gasket is exposed to extreme pressure and high heat and will naturally deteriorate. It could become faulty and create leaks or it could break entirely. In either case, a full replacement of the gasket is the only solution. This OEM part can provide an exact fit for compatible lawn and garden equipment engines. This genuine crankcase gasket is manufactured to strict standards by Briggs & Stratton and is compatible with select engines on lawn mowers and generators from Briggs & Stratton, Lawn Boy, and Toro. This gasket is made of durable composite material and it is sold as an individual unit. Other gaskets, hardware, or related parts are all sold separately. The repair can be done with just a wrench, but be sure to allow the engine to cool entirely before beginning any repairs. Always wear gloves and disengage the spark plug for safety when performing engine work.
