Got a question guys

[MNGB]

I'm working on the K301 12 hp Kohler the alternator is not working and the stator is dead so I'm installing a good use 15 amp one that going good have it on the engine went to blow the dirt and crud off the flywheel and found its missing one of the magnets, I have a K321 14 hp flywheel and am wondering how hard it is to remove the magnets would take one from the 14 hp flywheel and glue it into the 12 hp I know someone has removed them and reglued then

You have to heat on the back side of flywheel behind the magnet. Top little heat and it won't loosen the glue, and too hot and the magnet shatters. You will several chances to get it just right. Wit an acetylene torch it only takes maybe 3 seconds but imagine with a propane torch several seconds. After cleaning where magnet will go, I like to hit the area with a Dremel stone for more "tooth" for a good adhesion. I typically use slow cure JB Weld, but any slow cure 2 part epoxy works great. Just don't use any "quick set" glue as it isn't as strong a bond.

Can't you just use the 14 hp flywheel and be done with it?

Pretty sure They won't be in balance with crank on the 12hp.

Yes I just found that out the flywheels from the K241 thur the K361 are all interchangeable

Great! I had it in my mind they were differently balanced.

That was my thinking but the parts manual list the same PN for various and I asked on the Old Kohlers FB site to be sure and they say there the same and interchangeable
First off, all of the K241-K361 Kohler flywheels will interchange. The crankshaft tapers are the same. They're the same weight, too

I remember now that the crank balance is the issue between 10 and 12 from the 14 and 16.

Yes it is that's why I was hesitant till I got some solid evidence

My friend came to the rescue he had a flywheel laying around so I'll clean it up and install today

I used a flywheel from a K301 and put it on a K341 as the bolt pattern for the drive shaft adapter was different it shakes a little at idle but smoothed out at higher rpm.

Got the replacement flywheel and stator installed along with the cooling tins so this afternoon I;ll start the engine and check the alternator output

I thought the 10-12-14 were the same, and the 16 was by itself

You probably already know, but AC voltage from stator should be a minimum of 28VAC at high rpm, preferably 32 or more.

Yep will check that, and then the DC output, hopefully I 'd fry my VR when I was messing around with the other stator

Its working like it should, connected the wires installed a good VR started the engine flipped the alternator to on and ammeter jumped up to 10 amps volts were 14.6 so I shut it down and installed the VR i was worried I had fried started the engine flipped the alternator switch on and again 10 amps and 14.6 VDC so all is good thanks for the insight guys I appreciate the help
