Probably does not really matter here but learning from car gear boxes and differentials I always open the fill plug first. Reason being is if you cannot open the fill plug you still have a driveable vehicle and can go to a work shop for help whereas drain plug opened and no oil in the gear box...

Interesting that you saw more of those kinks. I have seen reductions or wider parts as a damping mechanism in Diesel fuel lines but I do not think that this is intentional. It looks to me as if something hit the pipes and pushed them onto the frame, the forward pipe has another kink on the...

The thread is actually M10x1.25. I am doing rear axle repairs at the moment, so I have everything apart. There is enough clearance behind the wheel hub, so I will simply turn the studs around with the long end pointing inwards. That saves me cutting them off; I could not find shorter studs with...

Thank you very much ! Yes, you can say that :ROFLMAO:

Fuel lines When I first looked at the tractor I had noticed that the fuel pipes were kinked, squeezed, to about half the cross section. I wanted to replace those. And while I am at it I may as well replace all the fuel hoses too. First I drained the tank and then took the seat and fender off...

I thought about that. The wheel nuts would have plenty of thread and would basically be flush with the stud then which is what I want. But the studs would be protruding inside the wheel flange, so I am not sure if they would collide with anything. The king pin bearings and the wheel bearings are...

Speed and brake pedal The speed pedal was all wobbly, the usual, lack of grease, hence rust and worn out. And the brake pedal had been crudely cut off, welded and bent to make it fit into a cabin at some stage. I removed everything and machined down the speed pedal shaft inside the bearing...

Brake switch repair My brake switch was faulty and I had it bridged with a wire. I had bought switches but it turns out they are the wrong ones, the brake switch is normally closed and opens when pushed in. It is always worth trying to repair things, you have nothing to loose and can't make it...

By profession I design electronics, mainly with embedded controllers, this makes it very easy to change functionality by changing software. But working on old Kubota tractors is way more fun :giggle:

For the design I use Visio (Version 5, before Microsoft messed it up). For prototype stuff I use an old Minolta laser printer with laser printable self adhesive vinyl sheets. But those labels I got printed professionally by a company in Germany together with the overlay for the instruments. They...

Some guy in Germany got the valve sequence of his Mercedes OM617 Diesel engine tatooed on his forearm so that he can tick them off when adjusting them ...

Hello, when I cut the grass at the site boundary last night, the neighbours fencing wire got caught in the wheel studs (he used strong wire, so I noticed before any damage was done). I had a look at it today and the studs are indeed protruding the wheel, something I do not like. I believe they...

Not sure, Kubota calls this thing "combination box", the box doing the pre glow timer and the safety functions and the engine stop. Mine was faulty so I designed my own. I included the status LEDs, error blink codes in the dash board (with glow light) and an override start mode where you can...

Glow plugs The engine had white smoke after starting for a few seconds. It starts fine though and does not use any oil. So I suspected the glow plugs. Checking them is easy, take the three nuts off that connect the power rail and take the power rail off. Take an ampmeter with about 15A range...

Finally finished the wiring for my modified instrument cluster and put it in the tractor. While I was at it I measured the glow plugs and found a faulty one, replaced it and white smoke after starting is gone now. Starter did not always work reliably, thanks to the LEDs on my home brewed...

This may well be. I have not done the maths. But in this case there would be a lot of material missing well outside the neutral axis.

Keep in mind that having the torsion bar through the arms would weaken the arms, so that has to be taken into account. As far as I can see the design is good but the welding was faulty. As a few people pointed out already: no penetration whatsoever. And that on a weld that looked good on the...

Was Joe Smith working for Kubota at some stage?

In the first year building the house I had 7 power cuts, some the whole day. So I added a small room at the back of the garage for a 16kVA slow running (1500rpm) Diesel generator. Engine is a four cylinder Mitsubishi Diesel. Runs fine and has been used regularly over the past ten years (once it...

I think a cutting deck with collector bag would work fine on this type of lawn.
