Engine Overhaul Kama 554

The reality show could be called.

The Man I Wish Was My Brother

lol, those ARE my clean clothes!
No really, it's always so dirty and greasy even clean clothes would look like that in about 5 minutes.

I'm leaning more and more towards leaving the pistons in and not balancing them.
Of course I still don't have the bottom end opened up yet. I hope I haven't let anybody down if I make that decision. But man, there is a lot of work removing just that front timing gear cover and housing. I'm not looking forward to remove the head at all. I'm still confident that the scoring on the old crank journal is the reason for loss of oil pressure. That's why I'm replacing it. Now, with a new pump and crank and new bearings, the bottom end should be good.

Leaving for work today, so I won't be posting until Wednesday.
See you guys later.

I think I speak for everyone, when I say that you won't be letting us down. Your doing a great job. Keep it up.

I'm looking forward to the day when the Kama's running again, and we get to hear more about all the great things you do with it!

Thanks Cyril,
I appreciate that.
Before I leave today, I will try to get the bottom off. I'm leaving the oil pan on since all the bolts holding the engine and what they call "main oil housing" are separate from the pan. I need to get that off to get to the journal caps. But like I said, I will look at if it is possible to remove the pistons safely without damage. But more important, that I can install them safely. If I don't feel confident about it, then I'll leave them in.

That sounds like a solid plan.

I think its unnecessary to balance them on a engine that does not even turn 3,000rpm. You will not disappoint me Rob.

the first thing I did was mark all the gears that would be coming off.

Curious as why you didn't use the original timing marks ?

Rob:
I'm glad I have not had to go that far yet into my JM284... I have to do the clutch very soon as I noticed when snow plowing it is getting even more weak. I think it may have cracked and or damaged spring washer... It happened a while back when my back was messed up and my brother was using it so I don't know exactly WHAT happened ya I know never loan out the tractor... I have a clutch, that I ordered when I ordered the tractor, though so far none of the parts I ordered have fit MY tractor. I think I got someones spare parts order and they got mine???

Maybe you can see the markings in the close ups? That way, I can line up the meshing teeth exactly the same as when they came off.

WILLL beat me to it. Weren't we just talking about the timing marks
on the gears? Or was that the Yanmar thread? I can see the factory
marks very clearly. I am glad Kama is doing it like the other Diesels.

You DO have to rotate the engine a few times, but miraculously that
little 'A' on the lower tooth will line up with the 2 'A's on the middle tooth.
Why didn't you use them?
