Nice job Tinbender! What will the final cost of your project be and how much weight can your pallet fork/bucket handle?
Homer,
That's great that you were able to find the problem.
Did you notice any oil mixing with coolant in the sleeve area? If you noticed oil in your rad there is a good chance that all your sleeves got contaminated with oil. While you've got the engine apart, you might as well take all your sleeves out so that you can clean them out – including the engine block area. We also replaced all of the o-rings on the sleeves.
Bob,
Sorry, I got it now.
We cleaned the engine block where the engine sleeve slide in as it was quite dirty in there and we flushed our cooling system on several occassion.
Bob,
Here's a comparison with old and new sleeve. There is cavitation on the new one as well. I believe that this is how they are formed.
The cavitation were not that drastic…we wouldn't of put them back in if we found them to be in that bad of a condition. We've been working the tractor quite hard this winter and with no problems.
Bob,
When we got the tractor there was water only in this area and we changed it over to the proper antifreeze for diesel engines. Here's what it looked like once it was cleaned.
Okay, if you've noticed that it's dripping from the front cylinder then yes that is a good next step to verify if the cylinder sleeve is cracked or if the o-ring around the sleeve is damaged. We removed and cleaned and replaced all the o-rings on the sleeves as we've noticed that the engine oil got mixed up badly into that area. We also cleaned out the rad.
I wonder if that oil port can be in the front of the engine head!?
Below are pictures of removing the piston and sleeve.
