It is not coolant. It is for sure unburned diesel. I am now waiting for the new valve springs and nicer weather. If the new valve springs don't help then I will have the heads done again, or I will buy the seat cutter to do it myself. I have the manuals and specs.

Today I have tried to get the engine to reach operating temperature. The outside temperature was minus 5* Celcius. (23* Fahrenheit) I had the whole radiator covered and managed to get the temperature gauge up to 70 degrees Celcius, (158 * Fahrenheit) but the bottom of the radiator was still ice...

After the rebuilt, the compression was first tested in the shop because of smoke and was over 300 PSI. The tester maxed out at 300 PSI on all 4 cylinders. All cylinders have their own head and head gasket. The tractor was driven to a field to be put on the disk. After disking for about an hour I...

I put the disk on it for one hour and worked it hard. The engine oil is regular Rotella 20W30 for diesel.

Each cylinder has it's own head and head gasket, no cracks in the block. It has sticky soot in 3 exhaust ports. One exhaust port is dry soot.

There was one cylinder in compression stroke for over 20 years. The springs were not compressed. That might be the difference. I didn't think they lose strength, many engines are older than this one, but who knows?

I have saved a Zetor 7045 from a farm where it had been sitting outside for over 20 years. The hour meter shows 2122 hours. The engine was seized, which was expected. I have replaced the cylinders and pistons and the valves, I have ground the valves/ seats. The injection pump is tested and...

The bolt is a M8. This is the plug to check the oil level. It is to small to be a fill hole. The fill hole is left on the axle. The drain hole is on the bottom of the differential. The M8 bolt sits in a plate, if it is stripped out, this should be easy to upgrade to a M10. Try Zetor-forum.de...

Ridgeway Enterprises is expensive. Look at "ATP Motor". Ordering parts from Czech republic is easy, much cheaper, even with transportation and customs. Usually takes 10 to 14 days. The parts in the picture were US dollar 340, and delivery costs with customs and brokerage about 400 dollar US...

We have a new to us Kubota M120 tractor (1900 hours) with an intermittent problem with the 3 point hitch. After starting the tractor the 3PH sometimes start to move up and down 1 or 2 inches or more by its own, the same happens with a implement attached. Other times the 3PH works without a...

Nice tractor! If you have a PTO lever with 3 positions, than one position is the PTO on engine speed, middle position is PTO in neutral, and one position is PTO on ground speed through the gearbox. I think if you put the High / Low in neutral, and the gear in reverse, than your PTO runs in...

I don"t know this gearbox, but want to try to help. Hopefully someone who knows more about this tractor will post. Maybe the tractor was in gear when you took the stick and housing out, or you put it in gear while removing the stick and housing. If you shifter has a H pattern and only has...

It is not moisture, the engine has a separate head and head gasket for every cylinder. They are all fine. The block is not cracked. If the heavy smoke is from the oil that was used on pistons and cylinders at assembly, how long will it take before it is gone?

I am working on a Zetor 7045 with a 7001 engine that was retired 20 years ago and left outside. The pistons were seized because the exhaust was not capped and water made it onto the pistons. The injection pump and injectors still had fuel in them. I have replaced the cylinders, the pistons, did...

I have a Kubota KX41. There are 2 quick connect ports on the boom. I want to use these ports for a hydraulic thumb. I can push the service port pedal "up" and "down", from a "neutral" position. In the "up" position the cylinder will extent and is strong. In the "down" position the cylinder...
