Hey very general in nature but I have a B2601 ( 25.5 HP- 3 cylinder). Any idea what the engine life expectancy is of the engine - in hours? I know that throughout its life it will need its maintenance but at what number of hours roughly would be the life expectancy of the engine?

I have some kubota engines at work with 10,000 plus hours on them. As long as they are maintained and taken care of you should get plenty of years out of it :D:D

keep the air filter clean, keep the radiator and screen clean, don't overheat it, and keep the engine oil changed....and adjust the valves once in a while, it'll last a long time. Unfortunately by time I see 'em they've been overheated multiple times and ready for replacement...did one a couple weeks ago (B2301) with 46 hours, overheated, junk engine.

Thanks good advice. what do you mean by overheated? How do you overheat the engine? in other words what do you do to it that would make it overheat?

Low oil, wrong type of oil, and or low radiator fluid, clogged up radiator inside or out will cause the heat to build up in the engine - without the dissipation of heat, metal will start to change shape, once it does - permanent damage will occur, seals and gaskets will split and it goes downhill from there - typically seizing occurs.

Radiator coolant will effectively cool the engine about 90%, the oil cools the other 10%!;):)

Checking the temp of any engine is very important and not to be overlooked!

Thanks very much. This is all good info for me. Have a Happy Thanksgiving. [emoji106]

Radiator plugged with dirt, operator does not know what the screen is for, operator did not pay enough attention to the gauges-which would tell him when the engine's running warmer than normal. Engine coolant runs hot because the external parts of the radiator are plugged with dirt/debris which restricts air flow across the radiator core/fins, which then boils the coolant. Continuing to run it, the engine actually got so hot internally that the pistons basically weld themselves to the cylinder walls. This takes a little while based on my own experience and it's usually accompanied by a gauge that's pegged into the red/hot area, the smell of boiling coolant leaking from the overflow bottle, engine loss of power, and finally the engine just stops. Usually abruptly, right after a loss of power. The loss of power is the pistons trying to weld themselves to the cylinders and the engine stopping IS the welding. Let it cool off and it might or might not start back up. This particular one did, barely, on one cylinder-or actually more like 1/2 of one cylinder (no power whatsoever, would barely self-sustain).

Neglected, that's all. Or operator neglect. His insurance picked up all but $250 of it. Sometimes I don't understand how insurance works when they'll pick up stuff like this but cant (or won't) cover a natural disaster damaged vehicle on a technicality.

Thanks. These are good to know. This is my first diesel anything so I will be mindful and maybe just make myself a checklist from this of stuff to check regularly. I know there is a screen in front of the radiator but didn't realize how important it is to keep it clean so maybe I should just check it each time and check the oil as well. Thanks again. Really appreciate your help.

Depending on what a tractor is used for some folks can go for years and the radiator screens stay very clean and air flow excellent. On the other hand if you are mowing a open field with 3-4 foot tall weeds with mature seed heads on the weeds a radiator can become clogged in less than 30 minutes.
