The Riva Crankcase Repair Thrust Plate provides a cost efficient repair option for damaged Yamaha 1.8 liter engine cases. This item can save your expensive engine cases after failures due to:
Driveline coupler loosening
PTO transfer shaft loosening
Nut on end driveshaft loosening
These failures can push the crankshaft forward and damage the thrust plate area inside the crankcase. As a result, the crankcase needs to be repaired or replaced. Our specially designed bronze bushing requires machining of damaged crankcase for installation. We recommend working with a qualified machinist due to the tight tolerances that must be kept.
