Crickets 4 #1 Posted May 24, 2021 I am refurbishing a 1980 C 165 Automatic ( 01-16KS01-1708 9203 ) with a Kohler K341 engine (K341 Spec 71303A SN 9724332 ). Would like to check the flywheel’s balance but none of the machine shops in the Wichita, KS area have a correct seized mandrel for this flywheel. Anyone know where one could obtain a mandrel this size (tapered approximately 1 1/8” by 1”)? Thanks in advance. Share this post Link to post Share on other sites
305 380 #2 Posted May 24, 2021 if i was looking to buy one i'd be looking at McMaster Carr or Manhattan Supply websites keep in mind that tapers in machining are usually expressed in degrees or inches per foot. for example the taper on an old Ford tie rod end pin is expressed at 1-1/2 inches per foot or 7 degrees. i'm not sure what 1-1/8 by 1 fits in if i was looking to make one i'd whip one up on my lathe. the machine shops you went to could not make one?

Could you see if someone has a crank shaft with a bad rod journal? Cut the flywheel end of the shaft off to use as a mandrel. 2 Share this post Link to post Share on other sites
WHX?? 51,732 #4 Posted May 24, 2021 Does it really need to be balanced if there is no metal or fins broke off it? Share this post Link to post Share on other sites
