Replacement Starter needed for K301 on Raider 12, Model 1-6251

[MarkS Indiana 0]

I have a K301, spec 47176 replacement engine on my Raider 12 that was installed by the tractor's original owner With this variation of the K301, a starter was not furnished. The K301 installation instruction manual calls for transfer of the starter from the engine being replaced and that is what was done. So what is in need of replacement now is the original red wheel horse starter.

 

There are many eBay listings for aftermarket starters for the K-301 from reputable sellers. However, two that I have spoken to have stated that their stock aftermarket starter for the K-301 is not a fit. If anyone here in similar situation has successfully installed an aftermarket starter that they can confirm is a proper fit, I would greatly appreciate it if you can provide the specifics needed for obtaining one.

 

Note: K301, spec 47176 installation instruction manual which as stated above calls for transfer of the OEM starter does go on to state that if a new starter is required it can be added using kit # 237693. However, my research online shows that p/n # 237693 and its replacement, p/n # 221520-S are now both discontinued.

  Glad to have another Hoosier!

 

The model you have (1-6251) is a 1970 Raider 12, and should have a K301S-47371C.

Is there mounting holes for a starter? Teeth on the fly-wheel? Alternator for charging a battery?

 

I was going to send you to a TORO link for parts, but it is by model number, and your Raider 12 model is correct..not the engine.

Try a KOHLER web site if no-one on here can help you out.

 

Sorry I am not more help to you, but if you wait, someone will come along and help you. Good luck with your tractor.

Thanks KC for the info and the Hoosier welcome!

 

Just to clarify, the grey replacement engine is spec K301S-47460. The original engine is long gone. However, I did find a green card-stock tag stapled to the Raider 10 & 12 Owners Manual with engine name plate info presumably from the original engine. That tag indicates just as you stated that the original engine was a K301S-47371C. Not sure why the substitution, but one thing these two K301S variations have in common is that the starter for original (spec # 47371C) fits the replacement (spec 47640). Therefore if you or anyone else knows of an aftermarket starter that is a confirmed fit for either of them I would appreciate the info.

Near as I can tell the original starter has been changed to 45-098-09.

This is a Stens dealer in Ontario Canada

Do a search for 4509809

They provide a good description of the motor.

This one will work but the gear is a little worn.

Here is another that will work:

I have interchanged many K241, K301 starters with no difficulty at all.  As long as the engine block has a caved in area for a little portion of the starter motor to fit, it will work.  Belt drive starter engine blocks DO NOT have this indent.

Thank you GWest and Fordiesel. What had me confused at the time of my first posting yesterday is that several eBay listings for used and aftermarket starters for K241, K301 engines show images of starters that appear to be almost mirror images of each other without any mention of the fact that two distinct variations of starters exist for these engines and they are not directly interchangable. The two variations are the high-mount and low-mount. I see now that the starter I need to replace on the K301S on my Raider 12 is a high-mount. For those in need of a replacement starter who follow, caveat emptor.

Aftermarket high-mount starter received and installed on K301 yesterday and it works great. However, a word of caution to those who follow down this road: The bore of the mounting holes on this aftermarket starter (9.6mm according to spec) is just slightly undersized such that the holes are large enough for insertion of threaded portion of OEM mounting bolt but too small for the unthreaded portion of the bolt to pass through. Therefore it is possible to get the bolts started into the threaded engine block mounting holes but then for the partially threaded bolt to hang up on the face of the undersized unthreaded hole on the starter bracket. The fix is quick and easy. I just stretched the unthreaded hole on the starter bracket to 25/64" on the drill press and called it good. However, if someone did not know this in advance and was not observant as to what was happening at the moment the partially threaded bolt hung up he could easily think the bolt was seating properly and proceed to torque it down. This would likely result in the unfortunate consequence of stripping out the threads of starter mounting holes bored into the engine block. 

 

Earlier I stumbled onto a posting or possible two on the need to drill out the starter bracket mounting holes on aftermarket starters. This along with specs from multiple online stores listing the same 9.6mm mounting hole spec suggests to me this might not be uncommon for aftermarket starters. I also recall seeing a posting the title of which was about stripped out starter mounting holes. I did not read the details because it was not the info I was looking for at the time. However, it would not surprise me if torqueing the partially threaded bolt against the face of an undersized starter bracket mounting hole was the cause.
