My grandson was given 245 tractor with kohler CV15s replacing blown kawasaki. Someone cobbled wiring got it running stuck org. pto on. It starts and drives. I believe Kohler had manual not electric pto. Most of Kohler engine label is rubbed off. 5-digit spec code is missing serial # is 2615113624.

245 is electric pto so kohler would need the 15 amp stator, drive pulley with 1" hole, pto with 1" shaft hole. Kawasaki had shaft size as 1.12X" bigger than Kohler shaft 1".

How do we grandpa's get into these things :tango_face_plain: Anybody been thru this, thanks...

First, is this a 245 or a GT245 ? Probably the older 245. On ebay you can buy a sleeve and a special woodruff key to adapt the 1.125 traction drive pulled to the 1" shaft of the Kohler. They work OK. They will not work for the PTO clutch. You will need to find a PTO clutch with a 1" bore that also has a pulley height that is within an inch or so of the original. You will also have to make sure the anti-rotation peg location is the same. You may need additional washers on the bolt. You may need a longer bolt.


If the Kohler doesn't have the VR on the lh rear of the cooling shroud then yes you need to find a stator, flywheel and VR from a junk motor. Throttle control should not be that big of a deal. If your Kohler has a separate choke then a simple push/pull set up is easy to do.

What about the muffler ? Might need some welding.

Is the 15hp motor going to have enough power for the deck ? 15 is usually seen on 42" with 17 to 18hp on 48" and 20hp and up on 54".

Thanks, its older 245. I saw the sleeve and have it bookmarked. Found 1" pto's will measure old one, thanks..

It has battery starter. I think VR was removed and leads were connected to JD VR behind dash. I have engine and tractor wiring diagrams and a meter. Throttle linkage and muffler are done, look stock. (don't know how) Because fuel lines are lose (wrong size hose plus no clamps) I haven't been able to check charging circuit. Fix that first. I won't been spending any big bucks until its running good, drives good etc.

I've seen 245's on e-bay and most have 48" decks. I agree doesn't seem like enough power.

Wish somebody who didn't know what they were doing never gave him "free" tractor. Maybe I'll be lucky and find real good deal on older JD tractor and use this one to pull carts, no pto.

I would look into parts from a LX173. Pulley and PTO should slide right on. But the sleeve would allow no change in belt size. Unless not all CV15S have same crankshaft diameter.

I have put together a number of free mowers. Trust me free is not free.

Thanks, I was looking for JD tractor that had kohler CV15s engine and electric pto. I don't understand the sentence "about sleeve not allowing change in belt size". I'm thinking crank is 1". I not sure what sleeve we are talking about, sorry. If engine, pulley and pto match I'm not sure what the sleeve is. If pulley dia is different I could try different belt.


Using info from rayjay I'm thinking this CV15S has 3 amp stator and no regulator for non/electric pto. Kohler chart shows 3 amp and 15 amp stators. That would mean that stator would need to be changed, regulator added. Not sure if flywheels are different. Since label on engine is wiped I don't have spec code. Thanks again...

 

[raisin1]

Free is not free. lol just like a free horse ha. I would try to use cv15, kohler pulley and kohler pto just like the LX173. After checking hole size. This may end up as a tower rather than a mower.

 

[JD-285]

The LX173 pulley may not be the same pulley diameter as 245. If it is different you may be required to change to a different belt length if you use 173 pulley.

If you use the sleeve and Kawasaki pulley you will not need to change belt.

My understanding is the crankshaft diameter is different between the Kohler and Kawasaki. Right?

 

[raisin1]

All good info and I will use it. I will look for donor engine to get 15 amp stator, etc and pulley. Then I can pulley that works best.

You can get around the low amp stator by putting your mowers battery on a trickle charge after every mow if you don't want to spend the bucks or do it temporarily. That is if your battery already has a good charge and you aren't mowing for hours at a time.

Ya I'm trying to fix for grandson. I have JD X324 for myself. I'm sure that going from 3 amp stator to 15 I would need flywheel with more magnets. I've tried to confirm online but no amount of searching has helped. I would just buy new VR and stator if that would do it. Haven't been able to go out in rain to look for correct scrap engine.

 

[JD-285]

I did the opposite I did a swap on a LX172 (same engine as a 245) to a Kohler (but not a CV15S) and just wired the stator into the JD stator wires that run from the VR and was charging 13-14 volts. My Kohler had the VR on side but I just eliminated it and figured I would need it some day for another repower.

Has anyone ever just removed the diode and tried wiring the stator into the VR? I would assume it would not produce enough amperage.

I bought a Craftsman LT4000 that had a 15 amp stator with a 3 amp flywheel. Thread here https://www.mytractorforum.com/14-craftsman-sears-forum/795241-got-lt4000-today.html
The battery wasn't charging because they didn't know to use a voltage regulator with the new stator. Post #16 shows the stator and 4 magnet flywheel, the 15 amp uses 6 magnets. I checked the AC output of the mismatched stator and flywheel and got 29 volts. How that translates to amps I don't know. Post #29 shows how I mounted the regulator. I have not had any problem with it keeping the battery charged but this mower has a manual PTO. If you could come up with a 15 amp stator it would be worth a try.

I have a 6 magnet flywheel from JD LT150 CV15S part #12-300-03 on the way plus 1" to 1 1/8" crankshaft sleeve so I can use Kawasaki drive pulley. I will get 1" pto. plus new bolt and washer.


I may connect new 15 amp stator to org. brown wires to JD VR under dash instead of buying kohler engine one. Will do point to point meter check using wiring dia.

kohler 3 amp systems use 4 magnets and 15 amps use 6 magnets with engine mounted VR.


Referring back to whether 15 HP will drive 48" deck I remembered mowing tall weeds with my 1978 craftsman 12/6 12HP 46" deck no problem.
