A Dongfanghong-70 bulldozer continuously broke two axles in operation. According to the operator, the axle inside the axle was lost due to looseness, and it was later replaced with one. The reason the repairman analyzed the broken shaft may be due to a problem with the newly replaced roller. After inspection, it was found that the rim thickness was 6.5 mm thicker than the outer wheel. After a 195 diesel engine was repaired, the power was reduced, fuel consumption was increased, the exhaust pipe was severely black smoke, and there was a thicker diesel smell in the exhaust. The reason is that in order to increase the compression ratio of the diesel engine, the operator added a hollow washer in the vortex chamber. As a result, the swirling motion of the compressed gas in the combustion chamber was destroyed, and the formation of the combustible mixture was seriously hindered, so that the fuel in the cylinder could not be completely burned. And black smoke.
