Q&A Section
Q1: Is the 4607609 compatible with the older ZX200 (Dash-1) model?
A: No. The 4607609 is specifically designed for the Dash-3 series. Earlier models use different port configurations and pressure settings.
Q2: Does the assembly include the swing reduction gearbox?
A: This part number typically refers to the hydraulic motor assembly. The lower reduction gearbox is usually a separate component, though they are often bolted together.
Q3: What are the signs of a failing swing motor?
A: Common symptoms include unusual grinding noises during rotation, "swing drift" where the cabin continues to move after the joystick is released, or a significant loss of swing power on inclines.
