let me state this, blow by is not terminal as a blow up , you can run this engine and we just can not say how long ( before blow by reduces compression till it will not run), it might even improve if it needs running hard to seat rings , this engine is of low hours. I have seen engine that were so worn the had to be started with starting fluid but once going would still work all day. I would not be in a hurry to do a teardown get some hours on it and reevaluate . Also buying a complete engine might be the way to go you will have a spare parts engine then unless a core is required which I doubt.
still a compression check would be your best move, it should not make any difference but engine oil for these is 15/40. how many hours are on the machine? You never know maybe it was not broke in properly , just thinking of this take a compression reading then run it hard within reason for 5hrs or so , make sure it gets to a good operating temp. 80 c or 180 f let cool off and take another reading and see if the rings seated any better. also check the oil in the injection pump, that gets over looked often. good luck
makes you wonder why they did that once in place where is it gonna go? just need enough tension to make the bearing spin in place.
I have a 50 hp foton and a 20 hp dong feng , I do not believe there are any zerks on my rear ends but I am gonna look. wow!
you might want to put wedges between the axle housing and the rear end , the more slender the better and tap them as you are using the slide hammer be careful not to mar the mating surfaces to much, file flat if you distort where the gasket goes.
maybe you could try a coupla c clamps on the housing and slide hammer and a extra set of hands . hopefully the bearing did not seize to the axle. good luck
good to hear you got the problem figured out , hope the new fix is better than the screen that was from the factory. A lot of people have had issues with them.
I know I would not have made it like that,, but I have two Chinese tractors each with about 1000 hrs. on them and I have not had those issues with the drive. All I can say is to look at it and make a judgement on what can be done to make it better , so let me ask this was that your binding issue, I assume it was. And try to remember not to run in 4 wheel drive on pavement, I think it makes it a design problem worse . later on
