    Kubota L4150 white smoke, no start

    Found the leak. Old hose clamp wasnt tight enough under dash. Do you know what would cause functioning problems between front and rear hydraulics? When I raise or lower 3 point implement, the loader raises slowly. Ordered an operators manual to see what all the levers do and hoping that...

    Kubota L4150 white smoke, no start

    I have 3 pt operation and loader works. Just slow hydraulics. I just played around with it a bit yesterday. Maybe they need to bleed some more.

    Kubota L4150 white smoke, no start

    Thats the area I am going to focus on this morning. There is a screw for the governor that was loose after my mechanic left me. There was also a spring inside the speed control plate that was sprung that I fixed. Maybe it is too tight now. Either way I should be able to figure it out Im...

    Kubota L4150 white smoke, no start

    New head gasket came in today. Installed and she fired right up. No throttle and no stop. Had to pull fuel line to stop. I will do some research and see what I can come up with for those issues

    Kubota L4150 white smoke, no start

    Believe it or not it started on 2 cylinders a couple times. Im guessing with compression on 5, it will do better. Thanks for the hope

    Kubota L4150 white smoke, no start

    I was able to get the company to send me back 4 good pistons. Now at least I have 5 to put back in the tractor. I am surprised these pistons arent available. Waiting for my last set of rings to arrive from back east and the head gasket from Japan to put this back together. Wish me luck...

    I appreciate that. Just waiting to here back from Kubota on pistons and/or company I bought the motor from that has my core. I am wishing now I would have just rebuilt.

    Kubota L4150 white smoke, no start

    A little update on this expensive used motor that ran at removal and was sold to me this way. 4 out of five pistons are broke between rings. Waiting to here back from Kubota to see if pistons are available in Japan. None are available in the states... Never trust someones word is the...

    Kubota L4150 white smoke, no start

    I know now what to look for in a used diesel engine. Thankfully the company has been kind enough to right their wrongs with discounts. The unfortunate part is that they said they were ordering rings and a head gasket on Tuesday. It is now Friday and the owner states he did not claim that and...

    Kubota L4150 white smoke, no start

    Compression on rear problem cylinders are 65 to 110. Front 2 are 270 and 310. Now I need to figure out how to correct this problem. Researching to see if its rings, valves or what? Glad I finally checked pressure and appreciate everyones help so far. I know enough to be dangerous and I am...

    Kubota L4150 white smoke, no start

    Found one more problem. Starter spring on governor was stretched out and not opening fuel rail on IP. Fixed, now getting darker smoke. Guessing I need to bleed more. What do the shops use to bleed injector lines and if cranking, how long do they take to clear. Also going back to throttle...

    Kubota L4150 white smoke, no start

    It has a manual pull fuel shut off as well as a fuel solenoid to shut off fuel. Solenoid is working correctly and manual pull lever is in and not stopping fuel flow. Going down this morning to pull a couple parts and look at diagrams for linkage of the governor and throttle linkage

    Kubota L4150 white smoke, no start

    Not sure what Im not doing that you told me to. Fuel shoots up about 3-4 ft from injectors. Update. I started it again today and it ran for another 10-15 seconds, then shut off. There is no throttle. Tried throttling up and nothing. So guessing now, this problem is related to this issue I...
