things are going ok, but not too great.

 

I did get my $500 package yesterday, with rings, gaskets and connecting rod bearings.  Funny thing is that it did not come with a new t state like other kits I have seen.

 

Not sure if you can remember the bad #2 ring or not, but heres a shot of the new standard ring.  Its roughly .020 gap, a little high for me.  The tolerances in the cylinder were at .010 taper as well as #3.  Now the #1 was great at .005 taper from the bottom.

The pistons are within specs as well, but again, its looking like I am needing 25 over pistons and rings.

I took the block to my machinist and he is going to soak it first to get rid of all the rust and gunk in the block.  When I first bought the engine, it was missing the freeze plug out of the head. This will be nice, and hes only charging me $20 to do it. 

Were is it?

I might be taking a quick right here.  UTsmitty has a l3e that he might sell me if he can twist my arm.  That would be a quick fix and I will then have a spare engine. 

Im not one to half az a job or quit before the finish, but if there is a way to complete a job correctly and using the brain god gave me, then by all means, "were there!"

Took UTsmittys engine and did a little swapping of the timing cover, injector pump, injectors and intake manifold, and wola!  I have a decent engine, that starts just about every 1st try.  I even went out today and blew some snow.

Indeed. This was a wrench in the gears, wasn't planning on tearing into the engine, but I'm glad I did. I learned a lot about my engine, and what it's weak points are, strengths and anything in between.

Unless I'm mistaken, it looks like the cylinder is cracked in the picture above.  You can see it almost in line with the gap in the ring.

Smitty, it sure does look like a crack.  Not a straight line like a mark made by placing rings/etc.  That would sure drop compression!!!!!

That would also explain the missing freeze plug when Ryan bought the engine... it's a shame as he's put a lot of time and money into it... I twisted his arm (a little) to buy my engine to save him some time, but it turns out it had a cracked water pump housing on the front cover... I wasn't aware of it as I had never unpacked it from when I bought it... But, using some spare parts from his engine and my engine he finally got one running... Hoorah!!

Now smitty, don't twist too hard.

Yeah, it runs fine now thanks to Steve. Like he mentioned, I had to replace the timing cover due to a cracked mounting bolt. I also had to replace the injector pump too.

I do wish these engines were a direct injection. That way I could hear some turbo wistle.

All in all, this went well., I still plan to look into rebuilding the old one and possible sleeve the blocks back to standard.

Ok, next question. Since this engine is a "indirect injected", referring to the pre combustion chamber, can I put a turbo on it?

Reason asking, I read that some direct engines have a low compression ratio, 14:1 or so, and would benefit to a turbo. Mine on the otherhand has a ratio of 23:1. Assuming compression remains constant at 330ish psi on all three cylinders. I would also assume that I could have knocking as well if I get too high a ratio.

Are these assumptions correct?

I'm always looking for something new to learn each year. This year, I want to turbo either this engine or the one in my Kubota b8200.

I was over at the shop to look at the block,  looks like that was a scratch in the wall.  Theres no crack and after talking with the guy, we both agreed that we will sleeve this engine back to standard or 2.9921".  The sleeves cost me 92.31 shipped, for 3 and he will do it for me at no cost.  Thats because I am hooking up a shop heater for him.

 

I think im still going to rebuild and swap the engine back in.  It would be nice to have a fully serviced engine.  I want to have 400 psi in each piston and be able to know its good for another 2000 hrs, or 15yrs, which ever comes first.

 

I will keep you posted.!

I'm no expert as you know, but I do know that many indirect engines are turbo'd... my Ford with the Navistar 6.9 Liter V8 Diesel is one example.  Bear in mind that at this altitude, you've already lost compression pressure.  A turbo helps the engine to be altitude-neutral... you'll need to be careful as to volume and boost pressure.

 

As for doing the engine on your B8200--I'd be careful since I think the engine has a lot of hours if I remember correctly... this could lead to problems with thrown rods, bearings, etc.

 

Regards,

 

Smitty
