If the cleaning inside the exhaust casing was insufficient during RH turbocharger servicing, carbon contamination may be left, which which causes the clearance clearance to the turbine wheel to be small even after servicing. servicing. When the turbocharger was operated under this state, “Carbon Touch” (interference of the turbine wheel with carbon deposit on the casing) can result, which can cause the turbocharger damage at an early timing due to imbalanced rotor rotations. In the HFO spec. engines, in particular, particular, which will will produce larger larger amount of carbon, we need need to check the carbon deposit carefully. carefully. In order to know if or not the carbon inside the exhaust casing was removed appropriately, we have fabricated a new tool, (cylinder (cylinder gauge). One can check check if or not not the carbon inside the exhaust exhaust casing was was removed appropriately by inserting this gauge into the exhaust casing. The table below shows the cylinder gauge, which corresponds to the respective turbocharger model and the applicable engine models. Please order the app appropriate ropriate cylinder gauge from us through Yanmar Yanmar Engineering Company or your distributor.
