    Anyone have any suggestions on getting water contaminated hydraulic oil out of the system?

    When I get time I’m going to take a small tank and add contaminated hydraulic fluid and put it under a vacuum to see if that may work, sounds like a reasonable idea. I have an old champ forklift that got water in the system thru a poor filler cap design, after draining the tank and changing the...

    Hitachi ex30

    I’m assuming you’ve already figured out your problem but I just replaced mine on my EX30. Mine was an intermittent problem so I changed it out. The new one works fine. I used a test light to see what the harness was doing. The black wire is the ground the other two wires, blue and blue with...

    John Deere 444J can monitor unit

    For an old retired guy I can sure stay busy trying to keep my ranch tractors running! I rent my 444J out in the winter to a snowplowing company so this last year it got a good workout. The latest problem now is the dash display. It goes thru the test cycle fine but then the gauges just stay in...

    JD 444J head bolt torque specs

    I finally got the time to put the head back on and was wondering how to get the 60deg extra turn after the 110 ft lb torque. I got to thinking there is 60 degrees between each point of a hex bolt “6X60” = 360. So I used a sharpie to mark one point on the head and another on the top of the hex...

    JD 444J head bolt torque specs

    I’ve had to replace the head gasket on my 444j and wanted to know the torque specs. I’ve found a few specs on google but just wanted to check here. Does it require oil on the bolts or dry? Any other tips would be appreciated. The machine is low hours so I’m not sure why it failed but it didn’t...

    John Deere 210le won’t drive

    Mine was located to the left of the brake pedals, basically on the fire wall. There is a photo if you look close you can see the brake pedals. It’s the size of a cigarette pack.

    310SG vibration

    I’ll have a new filter tomorrow afternoon and will check the old one then. It still has lift power but does seem a little slower. I’m not familiar with the pressure relief valve on that pump but I guess I’ll be figuring it out. Any thoughts on OEM, aftermarket or rebuilt pump, if that’s what...

    310SG vibration

    Plowing snow my 310SG developed a vibration in the hydraulic system. It vibrates when operating any hydraulic function. It feels like a sticky ram packing but it happens with all functions front and rear. Oil level is good and everything is greased. I’m suspicious it is the pump going bad...

    310Sg sudden no start

    I would start out making sure you have fuel all the way to the injection pump. Use the primer pump on the side of the engine. Checking for water in the fuel. If you have fuel at the pump then crack a fitting on an injector at the valve cover and crank the engine over to see if fuel comes out...

    Case 580C quit mid job! Engine won't hold rpm's

    If you are worried about the engine over revving you could try removing the pre cleaner next to the exhaust stack and find a stiff ball or something tapered that will plug the intake pipe and will shut off the air supply. You may want to pre test it to make sure it’s going to do the job. Make...

    John Deere 450H

    If you have a 450H you will have to recalibrate TCU. The unit is located on the left side above the battery compartment. Under the black plastic cover. You may have a controller that is very oxidized but if you can still read the display you should be ok. You should have a code displayed and...

    Cat Excavator Model 312CL will not take grease in track Adjuster

    A lot of track adjusters have a ball and seat in front of the zerk fitting keeping the zerk fitting from having to hold the extreme amount of pressure from the dirt building up on the idler. I don’t know if your machine has that setup but you may want check that out to make sure if you do it...
