My used kolher engine

[BigBill]

I purchased a used kolher engine that was advertised as a 12hp KH301 that turned out to be a 14hp KH341. The top baffle that sits above the head says 12hp on the label yet on the flywheel housing it says KH341. The size of this engine towers over the 12hp's that i have. I told this story a few posts ago.
Question #1
I tried to fit my 12hp muffler on it and it won't fit. The 12hp muffler is 1 3/8" ID and the exhaust pipe on the 14hp is 1 1/2".
This is my problem now I have a 1450 engine and i want to install it in my cub cadet 108. Were can i get a inexpensive muffler that will work? Is there a 1 1/2" ID mullfer that matches the orginal 10/12hp mufflers available for it?

Question #2
This engine has an internal alternator with a regulator mounted on the fan shroud and a regular geared starter, its not a starter generator setup. I notice that on my cub cadet 122 on the newly installed amp gauge I'm seeing a steady 10amp reading when its running. My question is when my 14hp is finally installed and wired up how many amps from the internal alternator should i see?

The bottomline is which one is better the starter / generator or the internal alternator for charging? Can i run more electrical lighting from the alternator? Headlites & tail lights plus maybe added lights in the front for running at night.(snowplowing)

Since i have my cub cadet 122 restored I'd like to tackle my 108 and remove the 10hp kolher and put in the 14hp and get her running.

I have used a nipple and a 45 degree elbow (plumbing fittings) to make the turn so that the muffler clears the front of the tractor. Then a cheap generic muffler.

The122 is overcharging if you are getting a steady 10 amp output. when the battery gets charged it should only show about an amp charge. The alternator system on the 14 HP puts out more than the S/G which can only handle the factory lights. The 1450 had an electric PTO and lights.

I been doing a lot of starts and stops its never run for a longtime yet so it can fully charge up the battery on my 122. The 122 is also my first amp gauge to have a steady reading its not jumping around. Some seem not to run steady on the charging amps on the gauges.

I need top look for a 1 1/2npt muffler all i see is the ones that look like the 7 or 8hp mufflers. The 1450 muffler is like $85 to $99. I did find a muffler that looks like the orginal for $45 but it says it fits JD's. But after using my neighbors 147 its kind of noisy so maybe the orginal quiet line muffler maybe the way to go. I'm just too frugal sometimes.....

I also got lucky again the 14hp kolher has the regulator on it. I just have three wires to hook up now. The starter, the ign and the charge wire to the amp gauge. I'm going to use the 108's orginal manual PTO.

I would like to install headlites on all of my cadets but i see there going up to $200 on ebay.....that bites I could buy another cadet for the cost of headlites. I wonder if there are any after market lites i could use that are affordable(cheap).

With my cub cadet 108 i'm also thinking of adding a 50" deck. I found a new housing for $65. I think with a little design work it may work out. Its a shame to waste all that extra hp on the smaller deck.

It seems the projects never end they just go on and on...

Isn't a K341 a 16hp?

[junkman1946]

You really got me scratching my head here. Everything I have on Kohler K-series engines says the 10, 12, 14 H.P. all share the same block casting. The 16 is threaded for a 1in. pipe thread exhaust, while the other three are 3/4in. also the 16 has 1 more head bolt (ten I think). Also my engines have the model # stamped in the crank p.t.o. end, end plate. Am I a New England misfit or is my "knowledge"that limited. Frank

I'll check the numbers again and post in the morning. I know the haed baffle says 12hp on the sticker but the flywheel housing say KHXXX I think its a 14hp but its larger in size over my 12hp cadet. I'm sure the exhaust pipe size is 1 1/2" OD my caliper says so plus i know my 12hp muffler won't fit it because its a 1 3/8"ID. I'm confused too. I may pull the head and checkout the bore and stroke so i'm sure as to what the heck is it. I should of took pics when i had the motor out of my 122 while restoring it. A side by side pic sure would show the difference in size.

[junkman1946]

Bill Dont pull the head. Every 16 h.p. K series single Ive ever run across had one more head bolt (10?) than the 10 thru14s. also the bigger exhaust indicates a 16. Thats good MORE POWER. I have swapped sheet metal between 14s and 16s before to fool the competition at tractor pulls. I am going from memory here, so get verification before you take this as gospel. Frank

[klejeune]

Also, early 16hp should have 13 cooling fins on the cylinder. The later 16hp only have 12 fins.

[BigBill]

The number on the fan housing is 321aqs sorry for the confusion but the exhaust port is 1 1/2" od. were the 10 thru 14hp engines take the 1 3/8 ID mufflers I'm still baffled here on what it really is. The oil fill port/pipe comes straight up on the left side in the rear. The flywheel cover has a port were a hose connects it to the air cleaner. Maybe someone swapped out the sheetmetal too. If its a 16hp thats ok too the more power the better. It just looks so much bigger than the 12hp i had out of the tractor.

The exhaust takes a 1" pipe, which is 1" ID and about 1-3/8" OD, unless the theads have been stripped and and retapped larger.

One thing to remember about Kohler engines and Cub Cadets. All Kohlers are not created equal. If the engine did not come from another Cub Cadet, you may have problems trying to install it in a Cub Cadet with doing some modifications. The Cub Cadets used a different oil pan and block base (smaller) than Kohler engines used in other applications, and the PTO end of the crank can be a different size, both diameter and length. The K series had 43 different crank noses (PTO end) for the K 321, 341, 361 engines

[BigBill]

Its a cub cadet and it has the 4 bolt setup on the flywheel already. Someone did say its from a 1450 here already. I'm not sure but it has a flywheel cover like on the 1450 with the air cleaner hose. I'm going forward and try to put it in my cub cadet 108. If its 14hp for sure i'd like to locate a 50" deck or make one for it.

I believe its a repower kolher engine because its gray like the replacement engines are and the dip stick housing is an off cub cadet yellow(faded) and probably from the orginal cub cadet it came from. Since it can be started up and ran on blocks I may check the rotation just to be positive before i change it out.

Since the exhaust port is a manufactured one by the factory with a little "S" bend in it and its 1 1/2" od I may checkout my neighbors 147 cadet to see what diameter his exhaust pipe is at the manifold too. The muffler specs does say the 10hp & 12hp & 14hp take the same muffler but my 12hp muffler won't fit it because its a 1 3/8" ID. I wonder if i can get by using the 10/12/14 hp muffler and welding a 1 1/2" muffler pipe to it so it will bolt up. Or i just may fab a new muffler.

The replacement engines for the models prior to the 800-1650 models were black, but all the engines in the Quietlines (800,1000,1200,1250,1450,1650) were black, original or replacement. If the engine is from a Quietline, it originally had a muffler box and duct work on the front of the engine, and the muffler for them is totally different than either the "pepper pot" or cross mount muffler on the earlier engines. The earlier K series in the Cub Cadets were K-xxxAS engines (A=Special oil pan, S=Electric start) and the Quieline engines with the ring gear flywheel and starter are K-xxxAQS engines (A=Special oil pan, Q=Quiet Model, S=Electric start). The early 7hp engines were K-161-T for retractable starter, or K-161-S for electric start, and the same for the 8hp replacement engine..
