whc160 74 #1 Posted February 21, 2012 Well this last summer Dad's C-160 was using oil. He does not use it any more in the winter so I decided to look into it. Found what a I thought was alot of carbon when I got the head off. Also the head gasket was blown. Then found the piston & cylinder were worn along with the valves. So I took it all apart & then found that the top ring was broken. Now going to do a complete rebuild. Here are some pics. Share this post Link to post Share on other sites

whc160 74 #6 Posted February 25, 2012 Took the block, head, & crank to the local engine shop. Checked the crank & it was still within specs. They are going to bore the cylinder & surface the head. Then set me up with all of the parts I need. Share this post Link to post Share on other sites
Martin 2,132 #7 Posted February 26, 2012 i really enjoy working on these big block kohlers too... dont have a k341 though, would like to do one one day to compare the power difference to the k241, 301 and 321. Share this post Link to post Share on other sites
can whlvr 993 #8 Posted February 26, 2012 so what kind of cash are we talking,im not trying to be rude,just comparing,i have a 341 13 fin that is in great shape,but id like to have it checked some time Share this post Link to post Share on other sites
whc160 74 #9 Posted February 26, 2012 I let you know the cost next week. They were only open a half day today & they will call me next week with a cost. Martin I have a cub that has a 10hp & it does not have near the power my 16's do. But I don't now if it is just sick or there is that much difference.

can whlvr 993 #10 Posted February 27, 2012 i have a 10,12 14 and 16 hp that all run really good and the 16 is by far the most powerful,its on a hydro and still eats up the 14 on an 8 speed,and the 14 is very strong,the 16 is a great motor Share this post Link to post Share on other sites
mattd860 162 #11 Posted February 27, 2012 so what kind of cash are we talking,im not trying to be rude,just comparing,i have a 341 13 fin that is in great shape,but id like to have it checked some time I recently had a shop bore the cylinder and grind the crank on my K341. They seated the valves and de-carbon'ed the head. Machine shop cost me $260 and rebuild kit + extra parts another $250. Hope this gives you an idea of the cost for a total rebuild.

Anglo Traction 761 #12 Posted February 27, 2012 Just to give you a comparison, it cost the equivilent of US$109 for a Rebore/Hone, Crank Regrind/Polish and Steam Clean/Oil coating on my K301 here in UK. I thought that to be a good price. Purchasing/Shipping and Import Duties on the Aftermarket Parts was US$145. Share this post Link to post Share on other sites
rmaynard 15,514 #13 Posted February 27, 2012 I had my K-241 bored, honed, valves seated, and block totally bead blasted for $55.00. Crankshaft was turned for $50.00 which included shipping both ways to a shop 130 miles away. Parts were all aftermarket and included new piston, rings, connecting rod, valves, seals and gaskets, for $90.00. If you can accept that aftermarket parts will work as well as OEM, you can save a lot of money. I also shopped around for machine shops and used two different ones for the work. Total cost for machine work, rebuild kit, and shipping was $195.00. Share this post Link to post Share on other sites
can whlvr 993 #14 Posted February 27, 2012 thanks matt and others,i just finished a m12,aftermarket and the total was 300 bucks,are you talking kohler parts mattd860,if so thats cheap,up here kohler parts are nuts for price,i got the complete rebuild kit for less than a piston without rings,but time will tell i guess,so far shes awsome Share this post Link to post Share on other sites
bowtiebutler956 650 #15 Posted February 27, 2012 I recently rebuilt my k301 using stens parts. The block machining was $110, thats $30 to bore, $30 to grind valve seats, $20 to deck block, $20 to surface head, and $10 environmental fee. The engine kit I got from a guy on for 103.99, that included the piston, rod, new valves, gaskets, seals, points and spark plug. I also bought a new governor gear for $25. The engine kit was all stens parts. The governor gear was kohler. The guy's store on ebay is called The Man's One Stop Shop, he was very friendly and helpful, and he has kits for just about all kohlers. I would recommend him to anyone who is trying to save some cash. Matt Share this post Link to post Share on other sites
can whlvr 993 #16 Posted February 28, 2012 thats who i got my kit from,the machineist said they seemed alright and he would use them too,after seeing kohler prices,when i do my k341 i want to do all kohler though,just because its my fav motor,shes not ready for a while though,shes still strong Share this post Link to post Share on other sites

squonk 41,156 #20 Posted March 11, 2012 My 16 big block smoked like a pig when I got it. The tractor had sat a lot. Ran some Sea Foam in the the oil and it pretty much stopped. I use about 2 oz. of oil an hr. when mowing.I would like to rebuild it but it runs too good for me to tear it down. Plus it's my mower and snowplow machine. My hydro went out last spring but I was able to find a good hydro motor and got it going again. I'm getting a spare hydro rear this year. Maybe next year I can locate a 16 spare motor and have it redone to drop in and not be without my favorite tractor being available. Share this post Link to post Share on other sites

whc160 74 #22 Posted March 19, 2012 Well the weekend came & the 341 started going back together. Still have a few things to put back on it. I ended up with $850 in Kohler parts & the machine work. Here are some pics & I put the balance gears back in. Share this post Link to post Share on other sites
