I don't know about the reconditioning but if you go to the trouble of splitting it see if you can use a 180 pump. We put a 180 pump in a 165 years ago and it lasted till I sold the tractor with greater capacity.
I don't have to split it as it comes out through the top of gearbox. I looked around and cannot find anything about a 180 pump. What are you talking about? Tractor size? Pump model?
This is going back now to the mid 60s when I was in jr. high school. I'm not sure if a 65 and 165 are the same in the hydraulics. But yes Dad had the dealer put a pump from a model 180 in our 165 to give it more lift capacity. A MF dealer could let you know if it would work I suppose. Now that I think about it wasn't there a model 85 built during the same cycle as the 35, 50, 65? Like I said I dunno if the 2 series are interchangeable but a pump from a model 85 of that era might work equally as well. Good Luck.
To conclude, I ended buying a new one. It is a later model than the original with a filter but fits the same. The thing is, it only cost $560. How do they or the chinese make such a precision little thing for that price.
I don't know how they make stuff that cheap. China can make precision stuff when they get paid to do it. Sometimes it lasts, other times it doesn't. I've got 7 old Deutz tractors that were made in the 1970s that have the mufflers rusting away. About 10 years ago, you could buy a replacement for about $800. This muffler is tricky, because it is also the exhaust manifold and has six short pipes that attach to the heads. In recent years, the muffler was unavailable, but I kept searching online to see if that would change. I found a Deutz supplier in China that was making them last year and could buy a container of them for about $38 each plus some shipping. But I didn't need 1000+ mufflers and later i found a supplier in the US who imported them and sold them for about $250. I got a couple and they work great. (so far) And look better than the homemade one I made out of desperation a while ago.
There is so much precision stuff coming out of China now, anybody who doubted the quality of it would have to dumb. I hear JD have set up a couple of factories or something over there.
