butter filling method
① Working device fills butter, the machine is parked normally, the machine is parked normally
Note: After filling butter, it works for 2-3 hours, and the squeaks are squeaking when lifting the upper arm, which is particularly obvious in summer. What is the reason?
Reason: There is a lack of butter between the pin and sleeve , and dry friction. In addition to adding butter once in the figure above, lower the upper arm according to the figure below, lift the front crawler, 20-30 cm above the ground, and add butter. The reason is that the direction of the large gap between the pin and sleeve of the working device is changed, and the butter is easier to inject evenly, extending the butter filling interval.
In addition, please check the dustproof skeleton oil seal on the empty end face of the seat. If it is damaged, butter is easily lost.
(The main arm supports the track downward, the front end is 20-30 cm away from the ground, the maximum gap between the pin and the seat hole of the working device changes, butter is easily injected evenly, and the squeaking sound is eliminated.)
② Rotating bearing inspection window fills butter
Every time, add it 90° on the frame, add it once, up to 30cc (about 24-27g) each time, and butter overflows from the bearing seal strip under the oil nozzle.
③ Butter filling and moisture discharge in the rotating butter tank
Loosen the bolt (1), remove the cover (2) and sealing gasket (3) and conduct inspection. If butter is missing on the tooth surface of the large ring, apply butter to each tooth one by one using bamboo slices, wooden sticks and other strip tools.
When there is a lot of moisture in the butter tank from the butter window, loosen the bolts (4), spring pads (5), remove the cover plate (6), and seal gasket (7) under the lower frame to remove moisture. The increase in moisture is caused by condensation, which is a normal situation. A small amount of water is mixed into the grease and emulsified, so there is no need to worry.
④Crawler tension check and butter filling and unloading tips (20T)
lower the upper arm, let one side of the track off the ground, and turn the track on the side for 1-2 turns. The size A=320-350mm is normal (as shown in the figure)
If A is less than 320mm, please use 19 sleeve + joint rod + ratchet wrench to loosen the butter nozzle 1. First loosen the track and tighten the butter nozzle for half a circle, turn the track on the side to see if the butter is discharged. If it is not discharged, loosen the track 1/4 and turn it. Do not loosen more than one circle! During the loosening process, hands, feet and other body parts leave the observation hole to prevent the butter mouth from falling off accidentally and ejaculate and hurting people!
⑤ Rotary motor reducer bearing butter filling
Butter nozzle (1) is most easily overlooked. The first 500 hours of work is used to fill, and the next 500 hours of work is added. The butter spills out from the butter relief valve (2) and stops filling.
⑥ Left and left and right joysticks and walking joystick pilot valve column hemisphere head supplement butter
Remove the pilot handle cover, apply a small amount of grease at the apex of the pilot valve column (1) and the rotation and sliding part (2), and check and apply every 1,000 hours.
