The darn dipstick: What is the fill level I should aim for? I have always split the difference across the dipstick in...

    Old B7100 - adding a temp idiot light

    Approximately a 1984 B7100. Has anyone added an idiot light for temperature? I don't need a gauge/sending unit - just a light on the console. But I don't see any plug or accessory location that a sending unit could be installed. It's gonna be another hotter than normal summer. (but what is...

    Old B7100 voltage regulator, 3 wire

    I'm finishing some things up on the rewiring project. I still have a few illusive opens, I'll find them. But here is a question: The 12v hot from the regulator to the battery connection (at the key switch) is directly connected to 12v positive to the battery (via the starter positive). As in...

    B7100 valve clearance procedure

    It's time. 40 years old and I doubt its ever been done. I recently ordered a valve cover gasket and thought I was good to go. I looked in the WorkShopManual and, yup, there are instructions. But the instructions have the engine on a motor stand, duh. I'm looking for TDC markings for each cyl...

    B7100D Manual, 1984, Electrical

    I'm getting ready to do some rewiring. Mostly everything electrical is out of service except for the Starting circuit. Just this last weekend I eliminated the bayonet connectors to/from the alternator/gen under the exhaust manifold. I was charging as recently as this spring but now not at all...

    Mystery Bolt/adjustment?

    '81 B7001 manual xmission: Under the seat, right side top by where the 3pt pressure line comes in and the diverter accessory valve is located is this bolt painted yellow from the factory. It has a lock nut on it so it seems to be an adjuster for something. I'm guessing its a pressure adjustment...

    '81 B7100 (B7001) Need differential exploded view

    Hi Folks, My toy tractor is down, kind of. Its stuck in low range. I pulled the cover with the shifter/MFWD levers and drained it down. Everything in the gear box is good. I can see where the range selector engages a yoke on a splined shaft and it goes through the gear case and into the...

    B7100 Replacement Starter

    In addition to some wiring restoration it was time to change out the 40 year old starter. It's been sluggish for quite a while and despite battery condition, new heavy cables, etc. it has just been something I tolerated because of the replacement cost. But a week ago I saw a whif of smoke coming...

    B7100 Std Hydraulic Tap

    Folks, under the seat on this tractor is a handle that diverts the flow from the lift arms for the PTO to an optional output. It has a threaded plug in it. Has anyone ever used this output for anything?

    B670 backhoe boom cylinder

    I was filling in a trench with the loader when I backed into a tree. Oops - the darnest things happen in low range. The yoke on the boom cylinder broke loose from the ram. It looked like it had been welded before and whoever attempted the repair, they didn't get much penetration. Anyway, I have...

    B7100D (1981) Xmission growl, 2nd gear

    Hi folks - my 1st post here: I've had the above referenced Kubota for many years. The hour meter was broken when I bought it so I have no idea how many hours are on it but its a bunch. I've been dreading the day but it has happened. The unit has always growled quite noisily in 2nd gear and...
