702854boy 502 #1 Posted 4 hours ago Would this still be salvagable or should we try to find a new block? 1 Share this post Link to post Share on other sites
WHX?? 54,997 #2 Posted 4 hours ago (edited) What ya got there buddy... not the best pic but crank will need to be ground fer sure. It looks like some chips off the bottom of the bore? Might be able to smooth them out and runner. Hard to tell the actual carnage from yer pic. Inspect the block carefully for cracks. Looks like a rod let loose.

702854boy 502 #3 Posted 3 hours ago (edited) Yeah, I forgot to check the oil on a leaky tractor and the rod grenaded, we just weren't sure if the engine was runable withe the little chunk and tiny crack at the bottom of the bore. This is the rod that came out of it. Edited 3 hours ago by 702854boy 1 Share this post Link to post Share on other sites
WHX?? 54,997 #4 Posted 3 hours ago Nothin we ain't never seen. Somebody's gotta go to mandatory oil check school tho. Tell ya right now yer looking at least 300 in rebuilding tho if it's even possible. new piston, rod, gaskets, machine work ...yeah all of that. 1 Share this post Link to post Share on other sites
Achto 31,004 #5 Posted 3 hours ago You will need to see if the damage extends into the travel of the piston rings. I have one engine with a chunk missing on the bottom of the cylinder that I rebuilt years ago. Runs just fine. Share this post Link to post Share on other sites
702854boy 502 #6 Posted 3 hours ago The piston somehow still looks okay and we have a k321 that I took the rod out of last night and it looks like it's all right so I think we'll just have to measure and make sure everything is in spec and if it is just take the aluminum off of the steel crank and we should be good to go hopefully Just now, Achto said: You will need to see if the damage extends into the travel of the piston rings.

According to our eyecrometers, it appears to be below where the rings and everything go. 1 Share this post Link to post Share on other sites

ineedanother 1,874 #9 Posted 2 hours ago Was that a standard piston or had it already been bored? Share this post Link to post Share on other sites
702854boy 502 #10 Posted 2 hours ago I believe it was a standard Share this post Link to post Share on other sites

If it's anything but standard I would seriously consider setting it aside before investing in a second rebuild. JMO. 1 Share this post Link to post Share on other sites
8ntruck 8,602 #12 Posted 1 hour ago I'd do some dye checking in the cylinder to see if there are any cracks. If no cracks, and all the parts fit and are useable, I'd grind the fracture face smooth to help preventing cracks to start there in the future. Share this post Link to post Share on other sites
