743 engine V1702 after repair.

[nester]

The engine is rigidly connected to the pump, to run in the engine after repair it is necessary without putting j-point? It would not be desirable to dismantle the engine once again. How it is correct обкатать and how long the engine after repair? Changed the piston with rings and liners, bearing all the standard.​

Are you saying its installed but without a U-joint? How did they do that? it should have a U-joint to take up and mis-alignment.

I meant that after engine repair, it it is necessary (I do not know as to tell on To English) обкатать. That is, that it has worked in the single. It to make directly on Bobcat?

Ah, no problem.
Just remove the engine mounting bolts, hoses and wires. It will simply slide off the drive pump shaft when you come to remove it.

It is a pity, but you don't understand me. I don't know English. And Google the translator is very bad, as I see.
I have already made engine repair. Also has put it into place. I wanted to know, how I should start to maintain it that it worked further long. Slow turns not to eat well for the engine. At first operation me interests. Or at once in full work?

Очень жаль, но вы не понимаете меня . Я не знаю английский. А Google переводчик очень плох , как я вижу.
Я уже сделал ремонт двигателя. И поставил его на место. Я хотел знать, как я должен его начать эксплуатировать, чтобы он в дальнейшем работал долго. Медленные обороты не есть хорошо для двигателя. Первое время эксплуатации меня интересует. Или сразу в полную работу?

To maintain the engine, do not use synthetic oil during its run in. This is at least 200 hours from memory. Synthetic oil is good at lubricating, but it will not allow the new rings to seat in the bores correctly. Don't keep the machine at one speed all the time, move it up and down, load it down too. You want to make the engine work, just like a new car. Do not let it sit idling for long times.
No need to make slow turns, you want the engine to get loaded down. Diesel engines need a good load on them or they build up with carbon.
Replace the oil and filter after the first 50 hours of operation, this will remove any particles that were not removed after machining.
Make sure you use diesel grade engine oil. Failure to do this will cause damage over time.
Hopefully that's what you were looking for.

In a manual - oil replacement in the engine each 50 hours. It in usual conditions. Or it not so?

In some manuals it says 50 hours, but some say 200. Its even printed on the rear door of some machines showing 200.
If you were a contractor, you would be changing your oil every week or two if it was only 50 hours of operation.
Its a good idea to check it every time you go to use it, watch the colour. Diesel engines always have dark coloured oil, it happens a lot faster than a petrol engine. You will get used to the usual light black looking oil and the really black look when it needs to be changed. Usually when you can still see through it, its fine. When you can't, its time to change it.
