    Hydraulic Cylinder Rebuild Question?

    Getting the cylinders apart aren't a issue, I just remove the nut on the gland and then hammer the gland into the cylinder. Once the glad is slid back I can remove the locking wire (snap ring) then the gland and everything just pulls out. I saw on YouTube that there is a locking wire or...

    Hydraulic Cylinder Rebuild Question?

    Ok, I have a John Deere 410 backhoe, all the cylinders settle on it so I bought new seals for all the cylinders a coupe years ago. I started with the outrigger cylinders and I did not have good luck at all. There is a groove in the end of the cylinder that a snap ring goes in. When I went to put...

    Yes the there is a good flow of fuel to the pump, I made sure the filter and the lines going to the injector pump was all bled out

    Ok, I pulled out all 4 injectors, hooked them up to the fuel lines and I wasn't getting much fuel, however after cranking it over a few more times with the valve cover off to check the pulse timing the injectors started spraying really good! I set a camera up on slow motion and just checked the...

    That makes a lot of sense, I tried using starter fluid to seat a stubborn tire and I would just light the tire on fire, I finally gave up on it

    I didn't test to see if it's piping on the compression stroke, I figure I'll sort out no fuel out first

    JD 410 engine problems after rebuild

    Ok, I am getting a good amount of fuel to the injectors. I did pull #1 injector and then hooked it back up to the fuel line, I held a piece of cardboard Infront of it and it seems like the injector isn't puting out any fuel at all which explains a lot. So I'm thinking either the injection pump...

    That's funny, I was just talking to my friend that told me to use WD-40 the other day and he said "unless they changed the formula of it" lol, can't wait to tell him. He used to be a semi mechanic in the 90's, I guess things have changed since then

    JD 410 engine problems after rebuild

    I don't know if I'm getting enough fuel to the injectors, it's kinda hard to know for sure, when I crack open the line on the injector it pulses out fuel, how much fuel should come out? I'm thinking my Kubota (20hp) tractor sprays a bit of fuel when the injector line is loosened. This just seeps...

    JD 410 engine problems after rebuild

    Thanks for the info, sorry for not posting, haven't had time lately. I pulled the valve cover off, turned the engine over to tdc and I put the locking pin in the flywheel and the valves are all adjusted properly. I removed the pin out of the flywheel and turned the engine 360° and then slipped...

    JD 410 engine problems after rebuild

    Thanks for everyone's info and help! I found out the valves were waaay loose, even a couple pushrods had fallen to the side. I have no idea what happened but I have all the valves adjusted properly now and it's no longer blowing back out the intake and it sounds way better. It's now puffing out...

    JD 410 engine problems after rebuild

    That's what I'm wondering, perhaps one got a bit of surface rust from setting. I'll pull the valve cover off today and see what I can find

    I'm sure the crank is the correct one, I matched up numbers when I bought it and I compared the two side by side and they were identical

    JD 410 engine problems after rebuild

    There is always a possibility lol I did put paint marks on all the gears and I lined them all up when I went back together so it should be correct. I replaced the camshaft but the gear only goes on one way. Although the engine is blowing back out the intake it is also puffing smoke out the...

    JD 410 engine problems after rebuild

    Ok, today I got the pump pulled and the dots were not lined up. I rotated the pump a half turn and reassembled. The engine is now blowing some black smoke out the exhaust but it is not starting. However it is also blowing back out the intake? I'm wondering about a stuck valve? Although this...

    The shaft slides right out of the pump, I believe the gear is pressed onto the shaft
