Cleans the hands too ....

Hello Joe, the way you fitted spring #140 in your post #512 looks plain wrong to me. This is based on how mechanical engineers mount a spring in a groove or hole typically but not on the sharp edge of the part. I do not have specific knowledge of this engine though. Kind regards, Hugo

Hello Joe, whatever you do, when you have the head on the engine do not turn it with the starter. Turn it by hand slowly. A valve is bent faster than you can say "upps". And read and follow all the good advice from others here in the thread. And yes, all that sand has in your pictures has me...

Hello Joe, hammering is always risky. In the video the seal has an end stop, that is not always the case. I would always try to push it in in a defined way. A thread in the shaft can be used for that purpose with a mandril and a bolt. Attached picture of mandril set for seal rings. Chinese...

Hello Joe, you can get kits of round adapters for pressing in the seal rings. Inner and outer rings of old ball bearings are quite handy for that purpose as well or any piece of pipe with the right diameter as long as the ends are at a perfect right angle. Or sockets or basically anything round...

I thought the whole purpose of this Forum is to support people repairing and maintaining their Kubota tractors. Joe may not have a lot of experience but he is making a huge effort and I think he deserves to be supported. He may make mistakes, but I think so did everybody starting repairing...

Hello Joe, another thing: not sure about some of the flat gaskets you had bought and their material and price. But you can get gasket paper in various thickness that you can use to make the gasket yourself. Put the sheet over the part and hammer it slightly with a rubber mallet or similar. The...

Hello Joe, it may be that those bolts cannot be used again. Are they tightened with torque only or torque plus a specified turning angle? If the latter it may be that they have to be replaced. In this case they are being stretched when tightened and you may be allowed to do that only a limited...

Hello, schematics of G1900 attached that has the same motor. Dynamo is bottom left, regulator top left. Charge light is leftmost of the block of three bulbs in the middle of the instrument panel. Kind regards, Hugo

Ok, so I definitely have to shorten the front link to get the front rollers off the ground. That leads to another question: how do you measure the height of the blades? They are covered all around and not easily accessible when the deck is on the ground. I can always measure the height as per...

Ok, great, thank you very much, that answers my question! Will shorten the bars a bit and repair the pin holes.

Ok, but did it lift the anti-scalp rollers? The deck is the wrong one on my mower, so the figures from the manual do not work.

Modifying it is no problem. But can you confirm that the front link is lifting the deck at the front so that the anti-scalp rollers are not touching the ground when deck is lowered down? At the moment I think the link is slightly too long.

Yes, you are 100% right, it is a stout little tractor. Will definitely keep going. Problems I identified so far: - steering knuckles rear wheels excessive play - wheel bearings front excessive play - front axle pivot excessive play - front axle grease nipple broken off - steering ball joints...

Hello, a newbie question regarding the cutting desk setup. It is an RC48-G20K which I believe is the wrong one for my tractor. I think it should be an RC48-G20K-S for four wheel steering. Somebody before had been very creative and cut off the front link and welded it together shorter. The rear...

Second test Replaced the bottom hose and filled everything with water initially. The anti freeze and corrosion protection has to wait until I get the other hoses. I want to flush the system a few times because I do not know what anti freeze (if any) had been used. Mixing the wrong ones can lead...

Fan belt replacement The fan belt was top on the long prioritised to-do list: Lugbolt here in the forum kindly pointed me in the right direction how to change it after I failed initially. First take the mower deck off. Then loosen the bolts on the dynamo, top and bottom. Just loosen them...

Combination box and coolant hoses The first thing was fixing the electrics. The starter motor would not turn. The solenoid is driven by the "combination box" which adds some safety features and also controls the preglow light and the engine shutoff solenoid. The switches going into the box are...

Hello, as some may have read already in another thread I rescued a G1900 lawn tractor that, I believe, would otherwise have ended up in a scrap yard. The last few years it had been neglected and is in very poor condition. But short wiring the starter I could get it running and it started first...

Hello Joe, another thing I would like to say about the heads. Although you got them nicely cleaned up with a grinding wheel and wire brush you have to make sure that it is perfectly level and straight. I do not know the tolerances on this Kubota head but typically we are talking 1/10mm over the...
