squonk 41,158 #2 Posted November 28, 2022 Probably just an end bearing. Fairly easy to fix. I you are unable, look for a shop near you that deals in starter/alternator repair 2 Share this post Link to post Share on other sites
Pullstart 62,916 #3 Posted November 28, 2022 @WHX?? doesn’t know a ton of things about a lot of stuff, but he’s pretty good with starter generators…. @Achto knows things too! 1 1 Share this post Link to post Share on other sites

Basically only 2 differences in them 1 - clock wise or counter clock wise rotation. 2 - The length of the body, short or long. You should require a long/standard length with a CW rotation. Here is a source for a complete S/G or a rebuild kit. https://isavetractors.com/electrical/starter-generator-parts/ One other source for a complete S/G. Part MES9193N http://www.psep.biz/store/kohler_starter_motors.htm I just opened this S/G a bit ago and plan on rebuilding it. Bearings were good, rotor was rusted to the magnets. 1 Share this post Link to post Share on other sites
45to70 61 #5 Posted November 28, 2022 OK< Thanks. Think will go with the rebuild kit. Am guessing it is a bearing. 3 Share this post Link to post Share on other sites

Most likely... me thinks Dan has you covered but any issues let us know. I generally enjoy rebuilding them 'cept for cleaning. Usually ther is a distinct bearing whine when time to replace but if it sat and looks like Dan's all bets are off. I have enough pics to do a tutorial on them ... should get off my butt and do it. I saves vid it is OK but doesn't get in depth on things that i feel should be addressed. The bearings are a real common one and I just order them off fleabay. Always some on the shelf. I have found the brushes seldom need replacing but it doesn't hurt. Since I am a horseaholic and most of my tractors are early 60s always have a rebuilt on the shelf too.

gwest_ca-(File Mod) 11,048 #9 Posted November 29, 2022 One thing that is often overlooked. The ends of the armature housing should be wire brushed to bare metal along with the matching surfaces on both end plates. A thin coat of dielectric grease on the cleaned surfaces will keep rust at bay till the next time it comes apart. These surfaces provide the ground circuit required. Starter motors should be done the same way. 1 3 1 Share this post Link to post Share on other sites
peter lena 8,637 #10 Posted November 29, 2022 @45to70 just noting the end bearing on the armature , excellent opportunity to pop off the end grease caps , clean out and refresh that lubricant , would also use graphite , on related slide areas , pete Share this post Link to post Share on other sites

peter lena 8,637 #12 Posted November 30, 2022 @45to70 glad you found it helpful , typically , whenever I am doing a service issue , its not a 1 and done , there are related areas that also need some help . rusty areas ? binding / sticking linkage ? electrical connections that could use new wire ends? corrosion / shorting chafing wires ? its the details , pete Share this post Link to post Share on other sites
