    I am resurfacing my head and I was wondering if i need to reinstall it with a shim or not. If so is there a certain way to do it. Do I need to spray anything on it to set it? Also I was wondering if there is a certain orientation that the water flange gasket has to sit. There is circular...

    How do yo change the belt on a B20?

    In order to get the belt on or off the main pulley it must come off the drive shaft for the front loader hydraulic pump. The drive shaft is sectional but still won't allow me to remove it due to lack of clearance. The only way I see is to remove the hydro pump. A big messy hassle. Is there an...

    How do yo change the belt on a B20?

    How do you go about replacing the fan belt with hydraulic shaft and pump driven by crank pulley? I loosened the piece between the two but it won't drop down.

    B20 - dynamo / alternator started smoking

    Cylinder Head Cover Breather Pipe

    It all depends how much time I have to run the tractor. I do run it for only 45 minutes at times but I also run it for 3-4 hours as well.

    Cylinder Head Cover Breather Pipe

    What does it mean if there is a whitish smoke that coming out of this breather pipe. Sometimes it looks worse than others. When the engine is running hot it does it more. Is this normal or is something wrong going on?

    Water Flange Gasket Replacement

    This weekend I blew my water flange gasket on my Kubota B20. This is where the t-stat is. I thought it would be a easy fix but looking more into it, it seems hard to get to. It sits right behind the water pump. But removing the water pump won't help either since the back of the water pump...
