I'm looking at a 670 with a serial number 29903894. Can someone tell me the year. Also, is this pump capable of operating a loader (what gpm and pressure does it develop). It has teloflo, but the pump is on the engine. Does that make it a closed center system? Please help!
 
That S/N shows to be a 1967 M670 Super. AFAIK all supers had the pump on the engine, I doubt it is closed center hydraulics. My M670 is a pre-Super with the pump on the backend. It may not be very fast with a loader.

Ok, next question. What is the probability of finding the parts to
make it closed center so I can have a good loader tractor.
Having no luck finding what I need/ want and not willing to pay
the big dollars for the tractors most feel you need for a loader (
fwa,shuttle clutch, synchro shift, etc) at least for the operation I
currently have.
 
Why would it need to be closed center to be a good loader tractor? They were open center for years, and worked fine, IMHO.

I don't think any Molines in that time period were closed center, so doubt if there are any parts that would make it so.
 
I have a Jetstar that was used in construction. It came with a loader and a pump where the belt pulley goes. Still have the pump, but no loader......
 
Partly going by Bryce's comment that it wouldn't be very fast. Used a U302 with a loader for years...only slightly faster than a pitch fork. I was also wanting more than two remotes so I wouldn't have to take the loader off every time I hooked something to the back. (My brother has one like that and it is pretty awesome even though the pump is all but worn out. It handles a loader and a backhoe easily)
Maybe beggars can't be choosers...
 
All you need to do is get a two valve assy for a loader. Then you will have a float position for the loader. Run the main pressure line directly out of the pump to the loader valve and then from the loader valve to the line you disconnected from the pump. The three point and romotes will operate as normal and you will have a satisfactoy loader operation. The reason your 302 was slow, was you was using the tractor valves for the loader, and running the fluid through the tel-o-flo slows everything down. Also the 670 has a larger pump than a 302
