Help repairing Jennings Pump

Postby Jetlag4now » Sun Oct 14, 2018 6:23 pm

Have a Jennings Victory Chief. Have to manually return handle after each play. Took pump apart. Large rubber gasket around front of the push rod looks good. Small rubber (?) gasket on inside of cap is worn. Several questions. What do I replace the small gasket with & should it be glued to the inside of the cap? Is this an air cylinder only -- no fluid? After cleaning the cylinder should the rod be oiled or greased? Anything else to know? Thanks!

The pump head is not rubber. It is made of leather. Very hard to find a replacement, Usually go buy some leather scraps if you have a leather store or buy a pair of cheap leather gloves a cut them up to the size your original pump leather is. The plunger side should not have anything around it, it should be free moving.

Thanks mechanic. Neophyte here. So I cut the leather to fit snugly around the push rod & glue it to the back cap? The plunger looks good & moves freely. Anything else to know?

No glue !! Just screw the new leather to the rod and ease it into the tube. Clean tube and all other parts first. A little oil on the rod 3 in one or 30 weight just with a cloth or use your finger. That should be about it.

Thanks again. Will do & post result. Just 1 more question as the leather was totally deteriorated. Should I cut it the size if a nickel or as large as the cylinder?

Take the original leather off and flatten it to get your diameter. It should fit over the brass spokes. then you carefully slide it into the cleaned tube. Suction should be right away. Then reassemble. :D
