Heat it up as evenly as you can, put some penetrating oil in there and GENTLY try to work it off. Once you get it moving make sure you wrap a rag around it so that the little balls under the sleeve don't go flying away in every direction like mine did. Once you have it off, give everything a...

Our 873 C series did the same thing, wasn’t being used enough and the float detent part of the spool got rusty to the point where it would actually cause the spool to stick and it was impossible to do any sort of precision movements with the boom. I took the valve out and apart and of course the...

You'll also need spacers to run tracks on an 873 as otherwise they won't fit between the tires and the frame of the machine. We couldn't even fit tire chains on ours without spacers...

Looks like a 640 series machine to me as well. The 643 had a 3 cylinder Kubota engine in them as was stated earlier, the 642 had either a Ford KSG416 4 cylinder gas engine in the early units or later ones cme with a 4 cylinder Mitsubishi gas engine while the 641 had a 2 cylinder Deutz air cooled...

Here's what the manual says as far as ignition timing… In my experience, the timing advances significantly more as the revs go up, but I don't have a timing light handy otherwise I'd go and see what mine is at different RPMs for you… On edit I also found the amount of advance in the...

It almost sounds to me like the centrifugal advance in the distributor might not be working… the reason they have you set the timing at such low RPM is so that the centrifugal advance isn’t in play yet. I’ll take a look in my manual tomorrow as I seem to remember you set the timing with the...

Oldmachinist unfortunately passed away a few years ago...

What you have there is the dealer installed hand control option. Definitely not the advanced hand controls, those were not available when the C series was built as far as I know…

Check and see if something is blocking your fuel supply. Not unheard of that someone dropped a rag in the fuel tank that would move and cover up the suction port… also check the electric fuel shutoff solenoid between the tank and the fuel pump, they are known to go bad as well. If it’s as...

Sorry Reds, I was thinking of Too Much Tin’s 753 with this video… as for your Mitsubishi I have no idea where to find parts for one of those. You could try Jensales.com, I got all the parts I needed for my Ford KSG416 from them, maybe they can help you…

How did you end up making out with this project? I came across this video just now and thought of you... this is a 773 but the 753 should be very similar if not identical...

If it saves you from having to take the new engine apart I would certainly consider doing it that way! Our 873 is set up the same way, however so far I’ve yet to have to take the engine out. There should be a subframe just above the main frame of the machine on some isolation mounts that you...

The engine is meant to come out as a unit with the hydraulic/hydrostatic pump. You undo all the lines off the pumps and the lines and electrical connections on the engine then you undo a few bolts on the subframe and the whole works comes out as a unit. Once you have it out you take the engine...
