The previous article said how to decompose, so today I will talk about how the car cranes are assembled after disassembly.

    1. Before installing the slewing ring inner ring and outer ring, thoroughly remove the old grease in the sealing and sealing groove, then apply new grease, and then seal the inner ring. Secure the seal to the elastic bolt turn of the rod (evenly tighten about 10-15 turns). Note: Apply grease to the ball and the support and adjust the gap between the ball and the stand.

    2. The steel ball and the support are alternately loaded into the support from the plug hole.

    3. Push the plug into the outer ring, tap the pin, turn over the top of the pin, and lubricate the slewing ring with grease.
