Previously, we introduced that crawler is an important vulnerable part of crawler pellet thrower. When the workpiece is constantly turning over, it will cause damage to the crawler. If it is used for a long time, it will reach the life of the crawler. Then, it needs to replace the crawler, here we will tell you the correct way to replace the crawler.
Here are 8 steps to replace crawler of shot blasting equipment:
Step 1: Open the round plate and the flower disc inside the chamber, generally, the fixed screws are in two side of the chamber cover, which can be seen when the cover is opened.

In these two cases, splint knife can be used to cut the crawler from left to right inside and start the crawler shot blasting machine. The crawler turns in a positive direction, and then the crawler can be pulled out on the machine.
Step 3: Roll the three drives apart and pull them out from one end.
Step 4: The crawler type needs to take out the supporting roller together. Before removing the supporting roller, the tightening screw in the lower left corner and the lower right corner of the equipment should be placed in the top position.
