WHX?? 48,815 #7 Posted February 10 (edited) Give Bob a cigar... now for the million dollar question. The bore is within specs so a std re-ring. Minor scuffing on the piston. Crank looks good. Would you on reassembly... A. Flip the piston & rod around. B. Pull the wrist pin and just flip the rod around. C. Replace the rod.

ri702bill 8,323 #8 Posted February 10 OK - much like the adult undergarments, it "Depends"... Sounds like you are pulling the piston / rod assembly out anyway to re-ring it. The piston is flat topped anyway, so that MAY not matter how it goes back in. That gives you a better look at the bore and the crank journal. Myself, I would reassembly just the rod and cap in the desired orientation, but using Plastigage across the journal, Torque the rod bolts and pull it back apart.IF the squished gage shows a problem, either a taper or oversized (not enough squeeze) it's time to address that. Possible turning the crank undersize and a new connecting rod. The oil hole is there to lube the cam - how does that look?? 4 Share this post Link to post Share on other sites

rmaynard 15,461 #10 Posted February 10 You Wisconsin boys are always looking for the easy way out. Pull the piston and do a ball-hone to get a nice cross hatch, and replace the rings. As Bill said, Plastigage the crank journal. No sense in doing the rings and such if you're not going to check the other stuff. 3 1 Share this post Link to post Share on other sites

Sailman 1,291 #18 Posted February 10 @WHX?? thanks for the thread. I am ready to pull the oil pan off my K-161 and this thread helps me know what to look for (rookie here). What does the scoring on the rod caps indicate? Poor oil flow?? Would they need to be replaced? Please keep posting here as I will be following your procedures on my first attempt at this. 2 Share this post Link to post Share on other sites

Never heard it run but was told ran when parked 40 years ago. 2 hours ago, squonk said: Lots of dirt in that engine No more than usual but certainly not enough tar oil in it. Perplexing part is my big end crank measures 1.855 spec max 1.850 but the after market part number on the rod suggests a 10 under rod. Possible my eyeball yardstick is off but off tomorrow to my official scorer. Going to get a new rod regardless. "Sides these s would be on my @$$ like a dirty DEPENDS. I don't do it right. 29 minutes ago, Sailman said: . What does the scoring on the rod caps indicate? My pleasure Sailman. I think it was because the rod was installed backwards and poor oil changes. The hole in the rod must face the camshaft. Also there are what are called match marks on the rod and cap. They must always be together and face the bearing plate.That puts the hole towards the crank. Pics in abit. Edited February 10 by WHX?? Pics 3 3 Share this post Link to post Share on other sites

If I recollect right you suspect a broken rod? If that is indeed the case the piston can then come out the top end. Yes start a thread and follow disassembling in the manual to the letter. Take plenty of pics. Edited February 10 by WHX?? 5 1 Share this post Link to post Share on other sites
