    Yanmar 1810D hydraulic won’t work

    You have mixed up a couple of hydraulic lines. Start by telling us how many lines connect to the loader valve. 6 or 7. Clean the valve body to make the port letters cast into the valve body visible. Dave m7040

    Normal set up of front end loader controls

    Many years ago I was an accident investigator for the Canadian government. I was sent to the scene of a farm accident where the tractor operator was crushed and suffocated by a large hay bale. He had been working on the loader and reversed the bucket hoses. He thought he could mentally...

    Broken PTO

    The video forum member Peace supplied is excellent. Here is the section from the WSM on removing the pto shaft. Does your machine have a mid pto and if so how is it acting. Before starting to take things apart, make certain the pto control levers are fully engaged. Dave M7040

    Kubota M9540 brakes

    My M7040 has a lever above the brake pedals which you pull up on as you depress the brake pedals. You should have the both pedals locked together before using parking brake. Make certain both pedals have same adjustment. Dave M7040

    Kubota LA 302 loader boom won't drop

    Suspect any quick connects in hoses going to loader cylinders. First open and re-set the connectors. If problem persists, swap loader arm hoses for bucket hoses to see if problem now moves to the bucket operation. Quick connects can and do fail internally. When swapping hoses, take great care...

    Did you have your multi meter set to measure AC voltage when checking the dynamo output? A common mistake owners make is to have the multiimeter set to measure DC voltage for dynamo output. Dave M7040

    M7040 sudden fuel line separation

    No barb does not exist on these valves. Plastic end was smooth and unbroken. Judging by the simple wire clamps Kubota uses all along this return line they are not expecting any pressure. I never have water issues with my fuel but that does not mean condensation coming back from the tank affected...

    M7040 sudden fuel line separation

    In my area a major storm is coming and because my wife is very ill, I was readying the M7040 and blower so I could keep our lane open for medical supplies or an ambulance. I backed the tractor out of its storage location and was getting ready to drive it into my heated work shop. When I got out...

    GX270 Electric start conversion

    I start my similar sized generator engine running on propane with a cordless drill. I was making up a bendix drive system with socket of the correct size (23mm) welded to it but my next try will be with a power bar rachet to act as the bendix drive. You need a drill with some guts. I have...

    Slow moving front loader

    Check you do not have a rear remote control valve that has not returned to neutral. These valves can be draining off the hydraulic pressure making the FEL work slowly. Dave m7040

    FEL loader valve body model LA211

    There are two styles of loader valve controls. A 4 position bucket control and a 3 position bucket control. You need to figure out which you have because copying someone who has a different valve than you do wont work. You also need to find and then study the hydraulic block outlet type on...

    Kubota BX2200 LA211 Bucket Actuator Seal Rebuild Photos

    If you are doing this regularly, why not make the special stretching and compressing tools Kubota's details in their loader shop manuals? I have attached the jig details for a different loader to explain what I am talking about. I think the idea of using the jig is to avoid any twisting of the...

    I’ve got a 45’ Eagle towable manlift and bottom boom is leaking down.

    The parts diagram you posted describes the cylinders as have a valve in the base of the cylinder. Likely it is some form of load check to prevent the cylinder from suddenly moving if a hose burst. A small leak in this valve would allow the cylinder to lower. I would remove the cylinder in...

    My Homemade Skid Steer Machines

    Post the brand and spec's for your motors. You need to have an idea of the torque requirements of your drive system. A quick and dirty way would be to remove the motor, rig up a way to connect a simple torque wrench to the drive and see how many foot pounds is required to rotate the wheels...

    Joystick Valve

    Why do you think you need a new valve? The one you have has 7 hoses which means a replacement must have a power beyond option. The common mistake owners make is buying too big a flow rate replacement valve. What this does is rob you of fine control of the loader. 10 gpm or even a bit less will...

    Looking for service manual for Kubota F3990

    Kubota hydraulics

    Does your loader valve have power beyond? The arrow "from implement," would be the loader valve power beyond port providing hydraulic flow back into the tractor system. Not certain if you have power beyond. 6 hoses on loader valve means no power beyond. 7 and you have pb. Most valves can have a...

    Kubota L3830D Hydraulic Issue - Low Pressure

    Kubota L3830D Hydraulic Issue - Low Pressure

    Almost always a plumbing error. Do not take the pump apart as you will create greater problems. The clearances in modern pumps are beyond the tools and ability of most mechanics. Your hydraulic pressure will always be low on an Open Center system until the flow is restricted so your test can...

    Pto shaft advice

    The parts illustration clearly shows a two section pto shaft with each section having two U joints and each being able to telescope. Deviating from this design carries significant risk. Woods would not have opted for this more complicated setup just for fun. This is not a China designed...

    Wood splitter hydraulic question?

    I regret that my advice is correct especially with the valves you are working with. I looked over the spec's for the valve you posted. The spec's are even worse than I expected with a max tank port pressure of 150 psi. Normally I see 450 psi as a valve's tank port spec.. When your second...

    Wood splitter hydraulic question?

    Your plumbing is completely wrong!!!! First, your first valve in line needs to have a power beyond circuit. This is usually an optional sleeve or plug which you buy and install. Since your latest valve is the newest, see if you can buy a power beyond kit for it. The power beyond option is...

    Snowblower for FEL, price, comments?

    I do not think you have the pto power to operate such a unit. Landpride recommends 52 pto HP. Consider that a minimum. Your NH has 44 to 46 pto HP depending upon the model of the main transmission. The manual transmission sending a bit more power to the pto. If every HP your engine can produce...

    Advice on using existing connections

    Your point: Normally a backhoe is just 2 hoses and when the backhoe is disconnected....those two hoses hook to each other It all depends on where the Backhoe valve is in relation to the relief valve. On some machines the BH valve is fed first in line from the pump. The BH valve then needs a...

    B73 Ber-Vac Snowblower

    I did some on line searching for the owners particular model. I think the reason it is not listed in the Bervac material I provided is because the blower is very old. I say this because it has a 3 blade fan. All their new models come with 4 blade fans He needs the pto shaft shear bolt it would...

    B73 Ber-Vac Snowblower

    This attached page from Ber-Vac translates some part numbers to real bolt sizes and grades. I suspect the owner has mis types the actual model he has and perhaps it is a 74 *PN 657199-10MM X 55MM GRADE 8.8 There are other 74 blowers with different shear bolts Dave M040

    GPM for a hay mower

    Are these mower conditioners not driven from a conventional pto shaft. The only hydraulics are to raise and lower but not drive the implement. If I am correct, then the hydraulic flow needed will be minimal. Dave M040

    Clearing snow (3 kilometer long wood trail)

    I live north of the St Lawrence river and maintain trails on the farms of my brother and myself. I like an inverted blower. When snow is not too heavy I can motor along at pretty good speed. A much higher speed than you could do with a conventional 3 pt blower. Greatly reduces the time to...

    Cause of pump damage?

    This is a question not a statement! Could the control valve for the implement, in this case blower but previously who know, have been a spool valve for a cylinder and not a motor? If this was indeed the case how would this "mistake" show itself in pump damage? Dave M7040
