Just bought a 1979 bobcat 732, machine has been sitting for awhile. Whoever worked on it before had tore apart the lift control valve due to the ears breaking off on the spool. Wouldn't be a huge deal but during the time it sat they lost the positioner( back cover for the spool) and the relief valve. Could have the spool fixed at a good machine shop and think I can find the relief valve but the cover is definitely something I need to find from the looks of it on the parts diagram. So my question does anyone know the best place to look for used parts for this machine? Not having any luck online. Can find parts for a lot of other ones but the 732 seems to be a pain. Thanks for any help you can give.

ooh..... I'm not liking your luck on that. From memory, there were two styles of control block in this machine, One was Gressen, i don't remember the other. If you have the manual, it should tell you how to work that out.
What segment is missing the cap? I'd like to think all the caps are the same, so you could technically make a cap by copying one that is still there.
As for the relief valve, it may be harder to source than you think, if you have a good hydraulic shop, they may be able to sort you out though. The lift section should be pretty much the same as the aux, as both have a detent position.
I worked on my 731 that would have had the same style valve bank, they are not complicated.
Worst case, can you talk to your hydraulic joint and see if there are any valves you could swap it with? As long as it's open centre and the same size ports and spool location, you should be pretty well ok.

Thanks tazza, it is the gressen cs. I had the drawing, got it ioff of bobcat online . The ales are pretty simple but the spools, caps Ect. Are different on each valve. First thing I was going to try was switching out spools from auxiliary since its not always being used but of course everything internally is different. I was wondering if switching the whole auxiliary valve with the lift valve would work guess that's something I need to research more.
That may be the best option.
If you need to look one up from specs, your flow should be about 12GPM

Someone correct me if I'm wrong but I do believe the hydraulic control valve on the 730 series is the same as the 740 series, or at least the earlier ones. Should make finding a used one a lot easier. Just for fun I looked up the P/N for the 732 is 6558497 and looking at Bobcat Parts Online shows the same P/N for the 743... Hope that helps.
