WOW! thats the phrase in my mind this afternoon. I have a real nice 706 gas that is in real good shape, but the engine was tired, so, I tore it down this morning. It had a small tap in the engine when it ran, did not use it much, just cause of that reason. Found out why it tapped. Sleeves were so badly worn, 4 out of 6 cyls, top 2 rings were broke, and all 6 pistons were cracked on the skirts! Sure glad I did not run that motor just yet, would have been disaterous if she let loose. I noticed 3 sleeves, on the distributor side of the engine, had a small chip out of them, at the base of the block. and they had knurled the piston skirts once before I had it. The rod bearings looked ok, couple of scratches on the surface of the insert, all seemed to have the same wear pattern on the bearing insert,,,, wondering if the broken pistons combined with the worn sleeves, caused the bearing scratches due to the excess movement. So, Im going to spec the rod journals make sure they are good to use. (I hope so) funny thing is,, the hour meter reads 2400 hrs, and still works. Wonder why such a low hour engine had so much damage? ran out of oil at one point? overheated, who knows? LOL anyways, Sure is a nice ol 706, a nice loader needs to find its way on this machine. Im looking for a sleeve puller, or to build one to work. Anyone have one to rent, or sell, or have blueprints to make one? Where do I find a new sleeve puller? is it worth the $$??? Any info would be great! Thanks! ChadS
