I have a 3.5 ton sams club Michelin floor jack , it needed fluid and when i took out the refill plug , the spring and crome balls came out , i picked up the parts and there were 2 balls ( big and small ) , i can Not find any info on the web about these , the Question is , IS there 2 balls or is there only ment to be 1 ??? and what order do they go back in ? thx
That wasn't the fill plug. That was the pump valve.
Small valve to bottom large ball on top. The spring usually goes between them.
thanks Steve , i tried that and didn't work , i put the small ball 1st then the big ball then the spring and plug, it WORKS , thanks for the idea though ,
Depends on which factory and work group made it....
Here's a diagram. The little ball goes in first, then the small spring, then the big ball, then the big spring. I've seen this in a couple of jacks:
Of the same dimensions, file size and a substring of the same file name, and excerpted straight from the site I had provided:
