Hi, I have a question regarding mower decks. I am thinking of buying a wider deck for my G1900 (18hp). A dealer told me that the rc60 would be too big and would require a tractor with about 30hp. The G1900 was offered with 48, 54 and 60" wide decks. So why would it suddenly be too weak? With...

Hi, I have a relay already but there is no signal coming from the combination box. All safety switch signals are fine and starter signal is coming too. The plan is to build my own electronics with identical function but diagnostics output added to see a blink code for the reason the starter is...

Hello Joe, that's great that you got the engine running ! Wrt the cables, I am not sure if I understood that correctly but you mentioned 6 gauge wire to the starter and 2 gauge wire from the frame back to the battery. The current flows in a circle, so both wires have to be decent cross...

Hello Joe, does this engine need decompression to start? If yes, is there a flywheel missing at the front? In my opinion it cranks too slow to start. I have an old single cylinder tractor that requires decompression, crank it until it reaches speed, then close decompression to start. This needs...

Hello Joe, sorry, "within spec" was based on the 300-500 psi mentioned. According to the manual it is outside the Kubota specification, but I would not get excited about it. Typically compression is measured with warm engine which you do not have at the moment. As somebody mentioned already...

At minimum yes, but within specification.

Ok, my oil dip stick is 280mm long. And it has 16851 on it, so I think it is correct. And the one on the Messicks web site 16851-36410 is with an imperial ruler, has only 8 divisions, so 11.1 inches, that matches. So for reference if somebody is looking for it: maximum mark is 92mm below the...

Hello Joe, take the injector out and put a tiny bit of oil into cylinder 3. Turn by hand first if it runs freely, then do compression test. If compression is good it is the piston, if it is still bad it is the valves. Maybe you can get the oil in through the intake or exhaust port. Kind...

I just checked the number 16851-36410 on Messicks web site and it shows a dip stick just over 111mm long (4.5"). I think mine is way longer, will have to check, it would be wrong then. If somebody could measure from the oil pan end to the minimum mark, the maximum mark and to the edge of the...

Ok, so the manual drawing is misleading. Probably "cut and paste" from somewhere else :) I will make a new rubber so that it fits tighly again like the transmission oil dip stick.

Hello 85Hokie, yes, I did run the engine briefly to fill the filter and then waited for the oil to settle. And yes, the angle makes a difference. So you reckon it is the correct dip stick? The picture in the manual shows totally different proportions. That the rubber is not very tight could be...

Hello, I am a bit confused by the oil dip stick in the engine. It does not even look close to the picture in the manual. It is also fairly loose in the block, this could be wear or possibly it is the wrong dip stick. When I did an oil change today I filled in exactly 3l as per manual and now...

Hello Joe, a lot of people are missing the oil on the pistons... Kind regards, Hagen

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...
