That tag shows the engine s/n 45V61187.
There is a support bracket under the governor housing that supplies engine oil to the servo valve in the governor, the governor itself and I believe the injection pump as well. There are o-ring seals between the engine block and the support bracket plus o-ring seals to the bottom of the governor housing. Probably one or more of those o-rings that are leaking.

No, you don't need to disassemble the pump. You need to check the support bracket connections under the governor section.

Testimonials

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
