Repair of hydraulic excavator slewing 2011-10-09
Sumitomo excavator S2800FJ Worked for 8664h. In a construction site, met with the weight of the dump truck excavator. Later discovered that the seal bearing rotary thrown a lot of butter, while the internal rotating assembly unusual noise when you turn, issued respectively on the front and left side of the machine, record player in the grinding . Stays with the bucket, so that the siding from the ground, then down, found a large set of pivot point blank range. Bucket and then at the end of the earth, so stick extended to allow a major slew ring bearing radial clearance. Rotary engine and transmission speeds were normal. Therefore, the trial judge swinging ball in the segregation units and damaged, thus increasing thrust and rotational bearing radial clearance, the seal may be damaged. The collapse of the rotating assembly. Ring and the outer seats in the bus terminal. Connected to the inner ring. Is that all away at all engine hoses and seals the tube head with a sheet of clean plastic. Carefully use a crane to lift and the outer plate screws would be cowardly, and were separated from the car and get (Note that the balance of the car) and turn-off is still connected. In Figure 1, to play out of the cone 2, then blocked with 3 screws to remove and then controlled the ball and the insulation of the wire. Defines all the balls and isolation, we found that two isolated groups of the original shape can be seen, all crammed into the rest of Chunky. The ball with a clean diesel, more than 30 bullets were serious and significant deformation Ma Hang, and the rest in varying degrees of pitting. After removing the outer seat, the inner and outer seat butter can clean the tracks, both inside and outside of the pipe and the left front of the Ministry (the machine direction for the former) in sunlight can clearly see the bites. Pelle took the equivalent of suddenly applied radial slewing bearing an enormous influence, which (as shown in sentences in Figure 2, nylon, soft) for Pan insulating Some sets of damage, such as continuing to work on the isolation damage is more and more sets, so that inside and outside the headquarters of the gap, butter rose from inside and outside are the site of the gap on the jet, the Career isolation kits, and bullets are not lubricated, thereby increasing the insulation kits career and bullets to cause damage when the noise and unusual rotary excavator wiring.
