Bill D 1,599 #1 Posted November 15, 2019 I have a muffler and elbow from a M10 that I would like to install on an M16. Will it fit, and do all Kohler K/M series engines have the same 1 1/2" exhaust port? Also, does anyone have any tricks for changing the crankshaft seals on these motors? Thanks. Bill.

Stepney 2,314 #2 Posted November 15, 2019 Crank seals? Honestly never seen a K or Magnum with that issue. You sure your crankcase breather is good? As for the muffler. I seem to think my 16hp K series has a reducer in the factory exhaust. 1 3/4-1 1/2" maybe? I know it's not the same as my 12hp. Haven't had a 10 in a while so I cant answer that one.

Bill D 1,599 #3 Posted November 17, 2019 There was 25' of rope wrapped around the crank between the pulley and the seal. The seal appears to be damaged. The breather seems fine. Share this post Link to post Share on other sites
