Precautions:
When pulling out the seat ring, please wear goggles and cover the access hole of the support frame with a thick cloth to prevent the seat ring from breaking and shooting and injuring people.
Operating steps:
1. Measure the inner diameter of the valve seat ring and select a suitable puller and a sufficient length of the claw pin shaft
2. Rotate the knurled nut left and right, adjust the claw to be at the lower end of the valve seat ring or the joint between the valve seat ring and the cylinder head, and leave enough space
3. Rotate the screw clockwise to open the claw with the top needle and make the claw tip contact the valve seat ring. Apply slight force
4.After taking out the valve seat ring, it is necessary to open the jack return valve to return it to its original position in order to extract the seat ring again
5. The height of the seat ring raised by this tool is 25m, and it should not exceed the limit when pulling the seat ring. The claw should not pull the cylinder cover body, otherwise it may damage the claw.
