4110 water pump rebuild--possible?

[al3]

Well, my water pump has started to seep fluid from the weep holes; bad seal. Can see the pump is designed with what appears to be a removable backing plate. Has anyone every rebuilt one of these? If so, where did you find the replacement seal?

Also, maintence manual shows an O-ring in addition to a backing plate gasket. Anyone that had their's apart know if there is still one in there? Dealer thought not. Thks

I'm not familiar with your pump but there may be more than the seal needs replacing?

Bearings?? Shaft??

IMO, if you can not replace the impeller as well then is probably not worth rebuilding. You can try to match up parts with a Yanmar dealer but they will probably not be able to look up parts based on s/n as it will not show any info in their system due to an mfg agreement with deere (typically). $250 for a pump IS steep I think but not too bad. Good Luck
