    Volvo EC25 looking for aux foot valve bi directional plumbing for a thumb

    I should've dug into may machine before posting.. Traced the lines, the aux spool has two lines going out to the boom. One is capped and the other goes out to the stick. I cracked the cap and I get oil when the pedal is rocked back. Looks like I need a hose and I'll be in business. Fingers crossed

    Volvo EC25 looking for aux foot valve bi directional plumbing for a thumb

    Soooo, I am in almost the exact same situation, though my machine is set up a little different. I'm trying to clarify what you did here, and see if it will apply to my machine? I have an EC25 and just installed a Manca thumb. The machine has two aux lines on the stick, and I mistakenly did not...

    replacement for my 773

    Hello, after plowing these last few rounds of snow, I'm realizing that it's probably about time to retire my 773. It's a 97, I've had it for the last 16 years and it's just too loose and beat to be anything other than a beater. I've gotten very comfortable with this size and power machine, and...

    Magnetic Plugs in Final Drives

    How about a small serviceable filter on the case drain lines? They come in many micron sizes, with JIC connections. I'm getting ready to replace the lines on my Volvo excavator, and have some picked out just for this. I had the idea to do it, after replacing the case drain lines filters on my...

    Mitsubishi diesel compression test

    New low hour engine on the way, $1500 shipped to my door. I'll strip this one down for spare parts.

    How to replace drive chains on a bobcat skid steer loader?

    careful, the sprocket edges can be sharp as razors. I didn't even know I was bleeding..

    Hydraulic filter issue

    grab a wide cold chisel and hammer. You want to hit it right where the outer skin crimps to the base, at the top edge of the filter as it's pictured. Hit it and make nice little dent that you can get the chisel in, and angled to help turn it loose. Been there, done that, it always works.

    Mitsubishi diesel compression test

    thanks for the quick replies. What is the procedure for a diesel leak down test?

    Mitsubishi diesel compression test

    My Volvo excavator has a sick Mitsubishi S3L2 3 cylinder diesel. Excessive crankcase pressure (oil spray out of the dipstick tube), starts hard, feels like its not running on all cylinders when cold. I've picked up a nice old MAC compression gauge but have a few questions. I pulled the glow...

    Mitsubishi MS40-8 swing motor issue

    If your machine has a swing cylinder for the boom to rotate the boom left to right (I'm not familiar with the mitsubishi machines) it will provide enough force to push loose dirt. The motor and mechanism to pivot the house over the track frame is just to pivot it, and won't take much more abuse.

    drive causes engine to bog and stall

    Further update. Took it out to use picking through a giant pile of logs, and clearing a path. Machine would bog when pushed hard. I looked the governor over and found the issue. Top of the housing was broken where the governor spring adjustment is. The screw still had the tamper proof cap, that...

    drive causes engine to bog and stall

    OK, as suspected, the RPM was low by about 500. Seems that the high limit stop screw (which has a tamper proof cap) had vibrated loose and in. The machine was not even pulling 1800 rpm. Adjusted it up to 2300 and all is better

    Loading a 4 ton minni x in a single axle dump truck?

    surge brakes are fine for small trailers, but with something like an excavator, you want independent brake control of the trailer and that means electric brakes. Even when you have the load bias set right, strong wind, or abrupt driving correction can set up some sway and you need to be able to...

    drive causes engine to bog and stall

    Loosened the tracks a bunch and it is 90% better. The engine does still bog down some, but is not nearly as easy to stall. At this point, I can at least use the machine while I trouble shoot the cause. I still suspect that the RPM is low, so I ordered diesel tachometer to check it. Thanks! SD

    drive causes engine to bog and stall

    Thanks for the advice about the tracks. Factory spec is 90-100mm of sag, I checked this morning and have half of that at most. I'll loosen it up, check, and post my findings. It's not surprising, the previous owners repairs have seemed to create as many issues as they've fixed. That they would...
