KC9KAS 4,744 #1 Posted April 9, 2016 I have a 16hp K341 engine that is going to be rebuilt. The crank has been ground down 0.010, and the cylinder will be bored 0.020. My question/problem is....I am having a difficult time coming up with the correct part numbers for the rod & piston. I have been looking at KOHLER part numbers thinking that if I get the right KOHLER number, aftermarket numbers will be easily crossed. If anyone can help me I would greatly appreciate it. The complete KOHLER engine number is: Model: K341 Spec: 71179 Serial: 3023500409 1 Share this post Link to post Share on other sites
slammer302 2,156 #2 Posted April 9, 2016 when i rebuilt my dads 16hp kohler i went on ebay and looked at the aftermarket kits one of the sellers had thier phone number listed so i just called and ordered what i needed and paid over the phone and it worked out good. 5 Share this post Link to post Share on other sites
pacer 3,177 #3 Posted April 9, 2016 I've rebuilt 4 of the single cyl K's using the after market parts from ebay and found their descriptions were well described as to what they were for and simply followed them to order and all came out good. Their "kits" I found to be really nice --- and INEXPENSIVE! 6 Share this post Link to post Share on other sites
rmaynard 16,344 #4 Posted April 9, 2016 Whatever you decide to do, order the parts first, then have the machine shop bore the cylinder to match the piston, and turn the crank to match the rod. That way if there is a problem with fitment, it's the shops fault and not yours. 5 Share this post Link to post Share on other sites

He didn't have any second thoughts about grinding the crank, but he did want the piston before boring the cylinder. I have to trust him! Share this post Link to post Share on other sites
rmaynard 16,344 #6 Posted April 10, 2016 My machinist would touch neither the bore nor the crankshaft without first having the piston, rings and rod on hand before starting. 1 Share this post Link to post Share on other sites
Shynon 7,482 #7 Posted April 10, 2016 took my 1045 motor in for bore and turn crank, bored .020 over he needed the piston, did not need the connecting rod as crankshaft is turned to .010 under from standard. Share this post Link to post Share on other sites
