Sprite/Midget 5-Speed Kit
Rear Crankshaft Seal System

As a result of numerous requests, Rivergate has developed a rear crankshaft seal for Sprites & Midgets. The seal system uses a spring backed neoprene seal, and is incorporated into the aluminum transmission conversion adapter plate. It applies to 948, 1098 and 1275cc engines. No engine teardown nor modification is required for installation, but the engine must be out of the car. It is designed to stop oil leaks at the rear of the engine whether they are from around the crankshaft itself, or if the leak is thru the machined surface between the block and the rear main bearing cap.

The crankshaft seal arrangement is furnished with a tube of special aluminum sealant. In addition to use with the seal, it is large enough to use to seal the adapter to the back of the engine block and the oil pump cover into the adapter plate.

The crankshaft seal requires a specially machined 5 speed conversion kit adapter plate. The plate is furnished as part of the conversion kit. In addition, Rivergate can re-machine any of our adapter plates built since February of 1996 to accept the seal kit. See the price list for information.

Also available is the service of machining the standard Rivergate adapter plate to allow for installation of the Bolt-on rear crankshaft seal available from several of the Spridget and Mini Vendors. See Price List.
