12Horse Paladin 1,038 #1 Posted June 19, 2020 This Horse keeps biting me...not fun. But, ah...funny n fun in it's own twisted way. Anyways, without going into everything that has me here again...how do i findout for sure if a/my 1977 c-160 hydro takes a 10 or 12 tooth starter? Ive had the engine cover off once already, n kno there was a 10 tooth on there, n that's what i replaced it with. It is not engaging. No broken teeth, either on the flywheel or starter, snd as b4, i dont want to keep ctanking it n then i DO break something (like whst happened to the last starter b4 i got it). Thsnks for any input.

gwest_ca-(File Mod) 10,444 #2 Posted June 19, 2020 The original tractor parts list included a parts list for the engine. There were 2 different engine spec numbers used in the 1977 C-160 Auto One lists stater number A-237534. The other lists starter number 450981 Both have gone through number changes including 4509803 4509807 4509809 They will all use the same starter drive if you can figure it out from the numbers. Found where one of the numbers above is listed with a 10 tooth gear https://www.bantasaw.com/catalog/viewproduct.asp?i=1475&p=7133 Is the starter slow to rev up? They need to be fast to throw the bendix to the end of the shaft. Garry 1 1 Share this post Link to post Share on other sites
Tractorhead 8,526 #3 Posted June 19, 2020 Based on Garry‘s suggestion about the slow revning. Maybe your Battery status wasn‘t full enough or a cell drops. did you check the Voltage on the Battery? Something between 11,9V and 12,7v must be measured. If battery Voltage is below, it can cause a too slow revning on the Starter. how much Voltage you can measure on the Starter leads directly while pull the key to start position ? it sounds to me the Battery Voltage or a worse wire connection shall causes your Starter troubles. 2 Share this post Link to post Share on other sites
953 nut 51,018 #4 Posted June 19, 2020 The 12 tooth Bendix Drive is used on the 8 HP engines with a smaller flywheel and ring gear. Do as @Tractorhead suggested and use some graphite dry lubricant on the Bendix. 1 Share this post Link to post Share on other sites
Tractorhead 8,526 #5 Posted June 19, 2020 Good advice Richard, I use just teflon instead of graphite, but only dry lubricant. All wet lubricants binds dirt and dust. 👍 Share this post Link to post Share on other sites
stevasaurus 22,197 #6 Posted June 19, 2020 We had something like this happen a number of years ago. If I remember, all you had to do was switch the gears. Both kinds fit the shaft. This was on a Kohler 10 hsp high mount starter. One other issue that came up was whether your starter is a clock-wise or counter-clock-wise. We had ordered one from Pat's Small Engine Parts and the wrong starter was in the right box. The Kohler's on Wheel Horses use clock-wise. Kohler's on Cub Cadets use the counter-clock-wise. I think that is right. Look on the bottom of your starter...should see "CW" or "CCW". 1 Share this post Link to post Share on other sites
