gt14rider 1,044 #1 Posted 9 hours ago Good morning, I'm replacing the rings on a k181, piston is 20 over, aftermarket type A piston, ( think its a stens ). Bought a 20 over, kohler OEM piston rings. The middle set of rings is different, (see pics) Can I use these kohler rings or do I need to get Stens ring. 3 Share this post Link to post Share on other sites

Achto 30,628 #3 Posted 9 hours ago As long as they fit in the groove, not too tight, not too loose. I just came across the same scenario on my K91 with what I believe is a stock piston. Original had a 3 piece ring set. NOS replacement is a 9 piece set. 4 1 Share this post Link to post Share on other sites
WHX?? 54,032 #4 Posted 9 hours ago I think you'll be ok. Many guys here use off shore pistons but elect to use genuine Kohler rings. Not a bad idea if the tractor is going to be a daily go to. I do use Little Red Barn rings if just a occasional tub puller. 4 1 Share this post Link to post Share on other sites
gt14rider 1,044 #5 Posted 8 hours ago THANKS ,I'll check side clearance of ring in the groove. Worked on a couple VW 1.6 diesels , a friends dad was a old VW mechanic, he told me you can use aftermarket pistons but he always uses VW rings, those little diesels got high mileage, I had one with over 350,000 miles and not a lot of wear. They would pop a head gaskets if you ride them hard and get them hot. 1 Share this post Link to post Share on other sites
