Fordiesel69 271 #1 Posted October 6, 2014 Video Here: http://youtu.be/I6bVzrxQRAU Purchased this tractor for the attachments. I think I already know just how bad, but would like to hear if from you guys as well. Can this engine be used as is? I believe this knock is a little more severe than others I have operated. I just wonder if and when she will blow. Share this post Link to post Share on other sites
C-101plowerpower 1,606 #2 Posted October 6, 2014 sounds like you got a diesel in there, doesn't sound too good for a gas engine Koen Share this post Link to post Share on other sites
Save Old Iron 1,571 #3 Posted October 6, 2014 (edited) can't see any opinion offered here to be better than the one you have already voiced. what we think does not change what exists. opinions on longevity would be blind guess-timates but I wouldn't plan on blowing snow with it this winter! pop off the head, wiggle the piston then check for crankshaft rotation without piston movement. that would be the beginning of an educated guess Edited October 6, 2014 by Save Old Iron 1 Share this post Link to post Share on other sites
Fordiesel69 271 #4 Posted October 6, 2014 Piston is loose as in needs to go to a .010 over, and it is also glossy finish on cylinder. But the rod I did not check, there is a titch of movement on the crank before piston moves. The piston does not bother me as it is not loose enough to bust the skirt. But the rod makes me a bit nervous. Share this post Link to post Share on other sites

SousaKerry 503 #6 Posted October 6, 2014 Well the crank is probably already worn beyond repair so either run it till it blows and deal with the aftermath, tear it down now for a winter project, or buy a spare engine and swap it out, you'll have a good parts donor then.

Fordiesel69 271 #8 Posted October 8, 2014 I adjusted the GOV up today by ear to match my 255 hr M14 speed. My tach showed only 3100. Now it shows 3550 to 3883 bouncing. The knock is hardly noticeable when at the correct RPM. Also I did a piston soak and man did it free up the rings, there is a TON of piston slap, and yes it is egg shaped. It also helped, but did not stop the oil burning, so I assume a good majority of the knock is from the piston slap as well. So I have decided to run it for a few hrs and see if it gets worse. If it is a rod / crank, it definatly will. If piston, usually not. I have a spare M14 and M12 that I acquired as a two for one special. I just hate to part with either as these are the only spares I have. Share this post Link to post Share on other sites

Fordiesel69 271 #10 Posted November 24, 2014 UPDATE: The tractor / engine is now my winter plow tractor. With decarbon, piston soak, and fresh oil it actually sounds usable. No, not good, but acceptable. I have a spare M14 / M12 to use just in case. This knocker uses 1/2 qt of 5w-30 per hour. I think the thick carbon was partially causing higher compression / detonation as it does not knock anywhere near as bad as in the video. Share this post Link to post Share on other sites
