Piston Rings for a MF65 w/G176

According to my M and W book from 1968 the MF 65 came from the factory with a 3 and 37/64 piston. Rounded off that is 3.58

M and W made a kit with a 3 and 11/16 bore that would convert over to 44/64 inch. That is 7/64 over bore or around .109 over bore. I am thinking you have a set of M and W sleeves and piston that maybe could be .109 over. One of the other guys said this also. I thought I would share with you the numbers from the M and W book. If you could find rings for the M and W kit then they might fit.??? Barrett Jones who drives a MF 65 with the G176 engine to feed cattle.

Just had another thought. M&W used to supply engine overhaul kits. They were an aftermarket parts supplier. They always advertized, "More Power Than When New" on their decals that were supplied with a kit. I guess the extra power had to come from a larger bore on their sleeves ? Maybe that is what you are dealing with.

There may have been other non-OEM kit suppliers that may or may not still be in business. I used a Sealed Power kit on my 65 about eight years ago. They may be a place to start your ring search if that is the route you want to take.
