Jrain 276 #1 Posted May 19, 2022 I am helping a friend out who has a B-80 , apparently the starter drive gear needs to be replaced , their is only 2 teeth left on the gear , the starter actuates in and out and spins ,it also looks like every thing aligns and fully engages correctly , my question is, what and why would this happen , also as far as getting a replacement drive gear or drive kit to install ,where would be a good source to get one , Kohler engine SPEC 181s 30461d , I believe it is a 1974 B-80 4spd ( model # 1-014 is all I can see on the ID tag.

rmaynard 14,897 #2 Posted May 19, 2022 New and used K181 starters can be had on eBay pretty reasonably. My last new K241 starter was only around $50. 1 Share this post Link to post Share on other sites
ri702bill 7,319 #3 Posted May 19, 2022 It is my understanding that the Bendix assembly is out of production and NLA. As @rmaynard mentioned, aftermarket complete new starters (made in the "offshore" facility) are available - search the Forum past postings - I recall there being issues with the fit on the K181 engines with the location of the holes; they are a direct replacement for the larger block 10 HP and up.

ri702bill 7,319 #4 Posted May 19, 2022 46 minutes ago, Jrain said: my question is, what and why would this happen If the Bendix drive is dirty, the linear motion is sluggish, allowing the starter to spin with the drive only partially engaged. Then bad things happen... 3 Share this post Link to post Share on other sites

squonk 38,928 #6 Posted May 19, 2022 8 HP starter is different than 10 HP and up. Bolts that mount it are above the starter as opposed to under it on the big blocks. I have a spare one here if you need it 2 Share this post Link to post Share on other sites
