    Pressure gauges

    hmmm, if I understand you correctly, I can use the threaded holes where the bolts of the cup fit to screw in a plate with a hole in the middle to compress the spring and then somehow get a grip on the head of the bolt to undo it? Even imagining that I can get so far, will screwing this bolt...

    Pressure gauges

    So you suggest I remove the actual spool from the control bank? wouldn't that cause lots of fluid to come out? I guess I could jam some clean cloth in there to stop it. I would also like to replace the spring on another spool as it is totally bent and the lever will not come back to neutral...

    Pressure gauges

    Hi there, I've been away for a while, got back and started working on the machine. so I have inspected all the linkages for the bucket, took them apart, cleaned them and checked for interference, they are all good... what I have noticed is that the spool will travel out about 1mm less then it's...

    Pressure gauges

    Hi John, thanks for the reply. The pump is a Nabco ph82518 I don't know if that rings any bell. I have 3 of them mounted in series one after the other, and they are all very compact, my guess they are gear pumps, but I cannot be sure. for the bucket, all the links are mechanical, that's why I...

    Pressure gauges

    Yes, a quick coupler is exactly what i was thinking of, only in a T configuration. I have to admit I thought about digital gauges, but then I don't know if they will fit the look of my banged up ancient dinosaur over here, I guess steam punk is more adequate for it, and for my wallet too... I...

    Pressure gauges

    thanks for the replies, is there a ball park figure for a 4 ton machine, my problem is that information on this ancient beast is really scarce and I am pretty sure the controls have been messed around with in the past, so I don't know how reliable the actual reading would be. on a related...

    Pressure gauges

    Hmmm, maybe my machine is older, therefore different in design, but if I follow the logic of the valves, it shouldn't make a difference whether I put the T before or after the relief, when that valve opens that is the maximum pressure in the system relative to that pump. So you think 400 bar...

    Pressure gauges

    So in your case it is installed after the relief valve? Would it not serve the same function if it was installed between the pump and the relief valve? I mean the relief settings will still determine how much pressure goes into the system, or am I wrong? Is there any way to know what max...

    Pressure gauges

    Hello all, I want to install pressure gauges for this old Mitsubishi MS40 I have. I am thinking to use T connection between the 3 pump outlets and the control valves bank, and I will be installing 3 pressure gauges, one for each pump. My question is what range of pressure should the gauges be...

    Mitsubishi MM40SR - Final Drive

    yeah, that sounds about right, you can keep the sprocket on and roll it on the ground if you have to move it far. Or you can disassembly it there and then, piece by piece it's much lighter. Don't forget to plug the hydraulic ports on the motor or you will get tons of crap in it. An impact wrench...

    Mitsubishi MM40SR - Final Drive

    Well, like Nige said above, the thing is probably totally fcuked, so at this point I think it's more important to check what parts you need to replace than to worry about where to source them. Then if you really struggle to find replacement parts, I can talk to a few suppliers here and see what...

    Mitsubishi MM40SR - Final Drive

    So, the "3 big bolts" hold everything together, if you undo them the whole final drive with the casing will come loose, and the ball bearings at the front and the back will end up everywhere. What you would need to do is remove the hydraulic hoses from the back and plug them and the ports on the...

    Mitsubishi MM40SR - Final Drive

    Hey man, congratulations on removing the cover, you solved the puzzle, somehow... If you look at the picture I sent you there is a ring of ball bearings between the plate held by the three bolts and the body of the drive, I don't see anything like that in yours and that's kind of strange. Either...

    Mitsubishi MM40SR - Final Drive

    What I do is I get a flat small screw driver and inserted between the plate and the ring, then push outward (i.e. make the wire go more inside the lip that retains it in the side wall. I do this all around every 20-30 degrees, if I see the whole wire moving I go ahead and repeat, if I see that...

    Mitsubishi MM40SR - Final Drive

    hi, if your drive is similar to mine, there should be a steel wire in the groove between the body of the drive and the front plate. You have to use a small pointed tool, like a straight pick or very small screwdriver. you run it along in the groove until you feel where the two ends of the ring...

    Mitsubishi MS40-8 bucket curls in when machine off

    So here are some pictures of this grease nipple, it's been raining a lot here last few days... It starts under the seat and ends on top of the turn table at the front of the machine. the swing motor is 90 degrees clockwise to it, to the right of the seat. It looks like it corresponds to the...

    Mitsubishi ms40-8 intermittent track problem

    Update, after using the machine without problems for about a week, I went and checked the oil level on the gear side. when I took the plug out with the engine running, oil came out even though the plug was positioned at the upper most level. also oil was coming out in pulses, so I figured the...

    Mitsubishi MM40SR - Final Drive

    HI, I have a Mitsubishi MS40-8, and I have also been through rebuilding a final drive recently. If you know what brand the drive is maybe we can see if it is the same. Looking for parts for mine was not easy but in the end we got it done. you can also send some pictures, maybe we can figure it...
