    B7100 with a slight mechanical issue.

    Don't overlook changing ALL the fluids including the steering box. My B5100e had a torn shifter boot and allowed water into the transmission prior to buying it.

    L48 oil warning light help

    Maybe a chaffed wire and jarring from the bucket movement is shorting it out. Since the engine has been replaced it's possible the wire is not routed correctly.

    Radiator antifreeze leak out of expansion pipe

    I have a "new to me" B5100E and in the days before they added overflow bottles on cars and trucks you simply didn't fill the radiator to the top and left room for expansion;) Just make sure the tops of the tubes are covered.:D Since the weather is warming, finally, the coolant is expanding...

    smoke from breather in B7100HST

    There is also a Shell Rotella 30 weight that I would use in your area of the country, it's in the white bottle. I find it at my local NAPA. Be aware there are three formulas of Rotella. Blue bottle is 5-40 synthetic, silver bottle is a blend and the white bottle comes in 15-40 and straight 30w.

    Kubota B5100D parts..

    As "ford-9in" mentioned it could be the adjustments for the compression release. Definitely check the pump timing too, not the gears but the mark on the flywheel and fuel starting to be pumped that's adjusted with the shims under the pump:D

    Kubota B5100D parts..

    Have you checked the engine timing?? Is the pin in the rack on the pump in the slot in the yoke? Are both springs connected?

    injection pump timing

    Having just gone through timing my B5100 (two cylinder, 500cc, same gear setup) I can give you a few hints. First one shim changes the timing a lot, so start there. Second the timing marks on the gears as shown above only come around every 138 revolutions of the crank:eek: This threw me for a...

    Need to purchase new starter for L2600DT

    OK since I was the first responder and got the e-bay starter I'll tell the rest of the story:D My old starter would about half the time "click" but not turn. Being a the person I am I took it apart suspecting it was most likely the switch on the solenoid. I also found the brush holder had...

    Hydro fluid fill location on B7100HST with Woods LS-72 Loader

    This won't help answering your question but my "new to me B5100E-P" had a torn gear shift lever boot and I suspected I would find water. I drained the fluid from the main transmission and the oil and water had mixed and a white foam came out. On the two axle reductions drains the water had not...

    Where do I start Kubota B7000 engine siezed

    It takes two things, a good product and time:) Personally I use Kroil that is also hard to find and expensive:o Trans fluid and Acetone is an interesting subject

    Not your usual oil thread, there is a difference

    The EPA has reduced the amount of ZINK in the oil so the automakers will warrant catalytic converters longer. The highest point of stress in an engine is where a NON ROLLER TAPPET rides on a camshaft. Such engines are likely to suffer camshaft or tappet problems in that area and in automotive...

    Looking for E-Bay injector results good & bad

    thanks guys:) I tried a local diesel shop for D850 injectors for a generator and with parts and labor it's the price of new ones at $60 from a local dealer. But at the same dealer it was $105 each for them for my D905 engine on another generator. I'll see what they want locally. A big advantage...

    Do it Yourself Mower Deck Replacement.

    thanks guys. If I were to have changed the size it would have been smaller. With my folding chute it just fits through the side gate in my yard. I chose the B5100 because of it's smaller size. Yes I laid the old one on top of the new material to mark all the hole locations:D JoBo

    Looking for E-Bay injector results good & bad

    My "new" B5100 had the saddest looking injectors I could have ever imagined and I'm surprised it even ran with them. I put in two that I had removed and cleaned up from a D850 powered generator unit, better but not really good. So now I'm looking for people that have gotten injectors from e-bay...

    Do it Yourself Mower Deck Replacement.

    Here's part 2, Notice the output deflector was added after I painted the deck. I tried it out yesterday and other than needing some adjusting of the lift mechanism it worked perfectly. I used 1/8" steel for the deck that I bought and 1.5"x.250" steel cut from some angle iron I had for the skids...

    Do it Yourself Mower Deck Replacement.

    About a year ago I started looking for a older smaller Kubota tractor to mow my small city yard. I found tractors meeting my requirements all had bad mower decks and I resigned myself that I would have to rebuild the the deck. An ad on Craiges list yeilded a B5100 sound but needing lots of TLS...

    Need to purchase new starter for L2600DT

    The starter on my "new to me" D5100 was getting worse by the minute. I looked on e-bay and found many vendors selling them and ordered the least expensive one from "Pat's Small engine plus" for $85.99. It's made in China and arrived yesterday. I was startled how fast it turned the engine over...

    Alternator / generator not charging

    I've had my water jacket/dynamo on and off twice in the last week or so and used a "Gear Wrench" to reach that almost impossible nut:o Every few clicks of the wrench I rotated the gear head 2 clicks and gained more travel. To make getting the nuts back on easier you want to have the threads...

    Cause of Excessive Diesel knock found.

    This was an "interesting" situation. I determined that with the all the "dots in the right places" once you rotate the engine the crank has to turn over 138 times for all the dots to align again. That happens to be twice the number of teeth on the idler gear. But looking at the key ways that are...

    Cause of Excessive Diesel knock found.

    I've owned my thirty some year old B5100E for two weeks and from the first I suspected the timing was too far advanced. At operating speed the knock was not apparent. A week ago I verified that it was and started to adjust it with shims. In the process between my old eyes and lacking a clear...
