    Deere 824K center pivot bearings

    The upper pivot doesn't have those spacers, only the bottom. I've has several smaller loaders with this problem and was able to install the spacer without splitting the machine.

    490e hydraulic oil leak

    You can drain the oil from the open swing gear cavity by removing a cover on the bottom of the X frame close to the rotary manifold. It's oval shaped and about 4-5 inches long and is attached with two screws. Be careful removing it, I've gotten drenched in oil more than once doing this. There's...

    JD550 starts & dies

    Check the return fitting in the cap on top of the injection pump. It's supposed to have a ball and spring in it to hold a small amount of pressure in the pump housing but if it gets plugged the engine will die when the pump housing pressure is equal to the transfer pressure. The fitting can be...

    Deere 824K center pivot bearings

    Check items E and H in the lower pivot bearing , they are the spacers that keep the lower pin located in the frame. If one is broken or missing that would be the source of the up and down movement. The shims only set the preload or end play on the bearings and couldn't cause the amount of play...

    JOHN DEERE 410 HOW TO DRAIN HYDRAULIC FLUID COMPLETLY

    I forgot to mention that it's best to use John Deere Hy-gard hydraulic oil or another quality that meets the same specs. The higher quality oil have additives that allow water to mix with the oil which is better than the water separating and and going to the bottom of whatever component it's in...

    JOHN DEERE 410 HOW TO DRAIN HYDRAULIC FLUID COMPLETLY

    Yes, the more cylinders and lines/hoses you can get the oil out of the better. Make sure you check the suction strainer in the bottom of the transmission case and replace the transmission and hydraulic return filters. You may have to change the oil more than once to get it cleaned up. It only...

    Dead John Deere 855

    Aside from parting this machine out I don't suggest buying it. It is not feasible to consider running it. The 855 was a beast in its day but JD never made that many of them. The engine should be pretty easy to sell and the transmissions will work in an 850 or early 850b but would have to be...

    160clc problems. Hydraulic stall.

    A good place to start would be to check the system relief setting. If the system relief is set to high or not opening the circuit reliefs will open and that will cause the overheating issue and excessive engine pulldown since pump discharge ( high flow ) instead of load sense pressure ( very...

    350G No high speed travel

    A few things have to be working and reading in the correct range for high speed propel to function. Both pump discharge pressure sensors have to be reading and pressure must be less than 1500psi , both pump control pressure sensors have to be reading higher than 2.25mpa for the controller to...

    Roosa Master DBG Injection Pump - Recommendation on Rebuilder?

    Check the return fitting in the top cap first. It's supposed to be a return check valve with a spring and glass ball in it to hold a small amount of pressure in the housing of the pump. If it gets plugged with debris or pieces of the retainer ring, when the pressure in the pump equalizes with...

    Caterpillar 320D Excavator Steering/Tracking Gets Stiff After Running for a While

    I would lean toward the rotary manifold. Pick one track up off the ground and try to run the track on the ground slowly. If the track in the air moves there's definitely leakage in the rotary manifold.

    Bell B25D brake pads wear

    The mud could be an issue but you need to make sure the exhaust brake and retarder system are working correctly. Since the front brakes aren't wearing at all you might want to check the rear and intermediate caliper pistons for not retracting far enough and make sure all the covers are in place...

    jd 450

    Can you put a picture of the control valve on here? Some of the older valves had a power beyond sleeve in the end cap to supply oil to a backhoe or other attachment. There are a couple o-rings that could be blown on it causing the hydraulic pump to load the engine with everything in neutral.

    jd 450

    It sounds like a spool in the control valve could be out of neutral. Does it have an auxiliary section that's not being used? If a spool in one section is stuck out of neutral the system pressure increases until the system relief valve opens and the engine is loaded until you use another...

    Hydraulic oil for Deere 200c

    You should be fine staying with the Citgo oil. JD and Hitachi really dropped the ball on hydraulic oil specs on all of their products for years. When you mix other oils with the 46HN ( Mobile 1 ) oil it's clear like water and when mixed with other oils it stains the oil a yellowish color and...

    deere 450clc fuel problems

    I helped a friend put a head gasket on a C17 ( I think that was the model ). We had Cat TM instructions but it took me a while to figure out the sequence to adjust the valves and then adjust the Jake brake rockers. It was a weekend project so the beers probably added some confusion! Years ago I...

    deere 450clc fuel problems

    I've worked on some Cat stuff but not a 3116. The sleeves in the JD6125 are stainless. Copper might be a better choice.

    2011 Deere 824K Parking brake

    No, that's not normal. The parking brake only holds 20 ounces of oil and a leak on it probably won't be noticed until it's to late. I don't usually recommend reman components without checking repair options but I do on this. The last time I checked a reman parking brake was priced for about what...

    deere 450clc fuel problems

    I've pulled my hair out over 12.5L engines ( especially in 450CLC's ) with this problem before. The problem I've found every time is compression leaking into the fuel galley in the cylinder. head between the bottom of the injector and the sleeve in the head. With the injectors removed the...
