Need help & info on Monitor
I just acquired a Monitor w/pump jack and need some input to help me along. I have read all the past postings on Monitors, which has helped considerably, but I still need more. It is type VJ, 11/4 HP, speed 500, Serial #44617. I pushed the stuck piston out with my grease gun and oil with no problem. My imediate questions are----When was this little thing made and what kind of oil ring have you people who have worked on these things, installed? The oil ring that was in it has a grove all the way around on the face, with no ports through the ring as some automotive rings have. The bore is 3 1/2" and the ring width is 3/16". Also original color. I see a few patches of gray paint which may or may not be origional. I will appreciate any help you good people can offer. I know, from reading posts from the past, that there are some very knowlegable people out there. Hope to hear from you.
