1. Walking motor wear I unit 1 Ingersoll Rand DD110 double drum vibratory roller after many years of use, the traveling motor cylinder and plunger serious wear and tear, the inner surface of the track orbit rail curve razor, rotary body, plunger And roller jam, piston, cylinder and other parts of the serious damage, can no longer work properly. This type roller walking motor mounting structure shown in Figure 1. 2. Select the repair method analysis that repair the roller walking motor has the following 3 ways: First, replace the assembly. The original walking motor for imported products, the market research and analysis, to replace the travel motor assembly method, each walking motor procurement costs 8 to 10 million, and the procurement cycle up to 3 to 6 months, affecting the roller normal use.
