    Kubota Super UDT2 Trans-Hydraulic Fluid Shelf Life & How to remove one of the drain plugs

    If the plug is a hex socket head plug the proper tool is a hex key - I prefer 3/8" drive socket style. The open bucket of SUDT2 will last years if you keep it covered and clean. You will probably use it up as makeup oil long before that. Dan

    What fluids do you use and where do you get them?

    Fear, uncertainty, and doubt is an effective motivator and hard to refute. AFAIK the only unique orange product is SUDT and you need to keep that in context. UDT is unexceptional UTTO in all regards except branding but Kubota still considers ot an acceptable alternative to SUDT. Dan

    Stripped oil plug threads lower knuckle

    More horse puckey. You have expressed your peference - I get it. But stick to facts rather than inventing mythical problems. You dont need a reamer for this job - that comment was in response to your silly straight sided tap drill comment. And as I said that step is commonly skipped even for...

    Kubota B21 low PTO horsepower

    The pumps are driven off the engine and consume engine output horsepower. That loss is seen at both the flywheel and PTO The manufacturer's SAE net engine HP measured at the flywheel includes that loss. The manufacturer's SAE horsepower measurement taken at the PTO reflects any additional...

    Regard to synthetic hydraulic oils and engine oils vs. Standard oils

    In todays world just about every "full synthetic" on the shelf is formulated with a blend of Group III+ and IV base oils. Even Mobil and Amsoil now use group III oils to blend their full synthetics. You will look long and hard to find and then pay mucho for a "pure" PAO (Group IV) formulation...

    What fluids do you use and where do you get them?

    Semi-synthetic is a nebulous marketing term and means it has some unspecified percentage of synthetic base oil in it. The percentage can be very small and does not have to be a PAO product. One would normally look at the manufacturer's product datasheet for a more specific description but...

    Stripped oil plug threads lower knuckle

    News flash - NPT tap drils are straight sided. You then have the option - usually skipped outside of a production shop - to use a taper pipe reamer to finish the hole. The exact same situation exists when using an STI . Personally I macine and hand tap a lot of holes and I own and use taper...

    Stripped oil plug threads lower knuckle

    If the strippef threads are NPT you use a helical pipe thread insert and tap and the repaired threads are tapered just as original. That helicoil may he a little harder tp get locally. And just for general information American pipe threads can be either tapered (NPT/NPTF) or parallel...

    That answer confuses me. Helical thread repair inserts always match the original thread. Dan

    Kubota B21 low PTO horsepower

    You are missing the entire point. Here is the original question which was why is the BX PTO horsepower less than other tractors with the same size engine. The answer to that question has NOTHING to do with the loader. PTO horsepower is measured on a stationary dynamometer and its relationship...

    Kubota B21 low PTO horsepower

    Perhaps you should re-read the comment to which I was responding and quoted. It was about hydraulic load not implement weight. But since you brought it up I suspect that loss/gain is also close to immeasurable. And absolutely the case sitting hooked up to a dynamometer which is how these OEM...

    What fluids do you use and where do you get them?

    I prefer Goose Island and usually get it at the golf course. All of the Kubota products I have tried taste like petroleum. :oops: Dan

    Kubota B21 low PTO horsepower

    Think about that. The only power loss is from the friction/resistance of the oil circulating through the neutral circuit in the valve. That is: For all practicable purposes immeasurable Does not go away or decrease when you dismount the loader. Dan

    Paint

    I have used a lot of both and the only real difference is drying time. The Majic takes forever. IMO hardner in acrylic enamel is a waste of time and money. If you want a hard durable finish use a catalyzed urethane. Dan

    L2250 hydraulic pump repair
