K321 ?
 

:Morning: Has anyone converted a K321 to a gear drive starter from the S/G. If so will the gear drive starter bolt on where the S/G bolts? This engine is in a CC149. Thank you for your time. :American Flag 1:

yes it does. as long as your block has the scallop above the mount pad for the starter. pretty sure all the 14 blocks did, I know not all the 10's and 12's did

:Morning: Thank you for your reply, I will check the block and if the scallop is there, I will have to gather up some parts. :American Flag 1:

My K301 in my 129 was converted. Just so you know, the front bearing plate, flywheel and tins also have to be changed. The flywheel with the ring gear is larger diameter, so the tins have to be larger to accommodate. The bearing plate has to be changed so that you have the bolt bosses to fasten the stator.

14 already has the larger bearing plate. might not have the cut out for the starter. I know the shroud don't have the hump needed

I'm not sure that the bearing plate has the bosses drilled and tapped for the stator.

:Morning: Thank you Guys for your replies. I have a few jobs in the shop to get out before under taking this project. I am not interested in going the stator route, If possible it will stay battery ignition. Does anybody know if the flywheel has the indentation for the ring gear? There is no pop out for the gear starter on the shroud, so that being was there any difference in the overall dia. between the gear starter and the S/G flywheel shrouds? Thank you for your time. :American Flag 1:

The stator isn't for the ignition, it's for charging. You can't run a starter AND a generator. The starter mounts where the generator does. You have to run a stator.

:beerchug: You are correct, I do not know what I was thinking. If I can get it worked out, I am going to run a small alternator. :American Flag 1:

Unless your looking for more amperage, a stator is an alternator. They cost less too. (Assuming that you have an engine to pull parts from.) Only real benefit of an external alternator is increased amperage, and if you use a small one, (like what the kubota's use) you aren't really gaining anything. I'd go with the stator. Just my :TwoCents:

there is no place to put a ring gear on the flywheel. the ring gear shroud is just a tad larger in a couple spots but should fit in a 149 with no issues. you could probably take a die grinder to the bearing plate to notch it for the starter if there's none there if you don't want to change it and you don't need a stator for charging. you won't weaken it. you will need the shroud with a hump and a flywheel with a ring gear. installing a stator does make for a clean installation. if you are thinking of using an electric PTO make sure the block has the holes to bolt it on.

If you don't use a stator for charging, the only other option is to mount some external battery charging device, such as an alternator. I guess a guy could just have no charging device, and just charge up the battery in the garage between uses. What a hassle. I believe, like Jon already stated, you will have a donor motor that will give you a bearing plate, flywheel, stator, shroud, starter, and possibly even a voltage regulator which you will also need. Like I stated previously, my 129 was converted and it all fits, barely, so it will also fit a 149. From the new engine mounted VR, you will need a single wire to go to the load side of the amp meter. :bigeyes:

Matt,
I had to read Don's post twice. Look.


He was saying IF you don't need a stator for charging, not saying that he didn't need one. I read it wrong the first time too. :beerchug:

He went on to say that a stator is a cleaner set up. And, I would agree.

Thing I'm curious about on your 129 Matt is the rod for the PTO. Does it clear the starter? Or did it get modified too? :bigthink:
If it were me, on a 1X9, and I was going to the trouble to change the motor to an AQS, I think I'd just put an electric clutch on it too. Why not. :Huh:

OK, so you are right. I read it wrong. Sorry.

The PTO linkage clears the starter just as well as it cleared the S/G. The starter is slightly lower and back towards the flywheel a little, but not as much as you may think. The link is original.

I've thought about the electric clutch, especially since this tractor needs to be rewired in some kind of bad way, but the mechanical clutch works great, and if it should ever need to be rebuilt, I would probably rebuild it with the double springs for extra clamp load just for any how. This is cheaper to boot.

Here I am hijacking someone else's thread.

:Morning: Thank you Guys for all your replies. After doing some research and checking the prices on what new parts are still available. As I have no donor engine and unless I can find some good used parts/another K-321 that needs rebuilt and is set up for gear drive starter, this project is not going to happen. If it does happen you have conviced me to go the stator route. Matthew, hi-jack the thread all you want, this is valuable information. As for the E-clutch. I will pass as I just recently rebuilt my clutch and it has the double springs. :American Flag 1:

A donor engine could be a K-241, K-301 or a K-321. All have interchangeable pieces as far as these components are concerned.

:Morning: Thats good to know, now I have three options for engines. :American Flag 1:
