Lately when I go to start my PT-422, it will click two or three times like a dead battery then it will start to turn over and start. Is that a sign that the ignition switch is starting to go bad. If so does anyone have a part number and source for a new one.

Thank you,
Frank

Try checking to make sure your ground is making good contact

Mine does the same thing. Its been doing it for a couple years. I'm going to replace my starter solenoid before winter, just to be on the safe side. I may also replace the ignition switch, as it has been frozen with ice a few times in the last two years. At 14 years old, it can't hurt.

Squirt some WD40 into the key slot and work the switch a few times.
Th WD will re dissolve the dry caked lubricant inside and basically overhaul your switch. (it is non corrosive)

check voltage at solenoid when key turned to start and it is clicking.. if it is getting full 12v, then suspect the solenoid.

Don't love WD 40. It attracts dirt and this repair would be temporary in that case.

I was aware of using Electronics cleaner spray, then spraying graphite, that seemed to be the better solution. Costs more, though.

X2 on this one. Use electrical contact cleaner and follow it up with a dry contact lubricant such as graphite, or teflon.

WD40 is "Water Displacement, recipe 40", a light mineral oil and it will attract crud into the switch that you don't want.

A volt meter will certainly help you figure out if you are getting 12V at the starter solenoid, or not, and you can work backward from there.

Good luck,

Peter

I did squirt WD40 in the ignition slot before I read the later posts. It did not help. I will try using a volt meter to the solenoid.

Well crud! I pulled my PT up onto my trailer, shut it off. Got the truck hooked to the trailer, got out the chains to chain the PT down. Went to start up the PT to position it on the trailer for good tongue weight and....

no clicky.

:banghead:

:laughing:

Got an ignition switch at Rural King for $9.99 and that didn't change it at all. Put 12V across the big terminals on the starter and it spins but doesn't engage the flywheel. Pulled the starter and took it to a local lawn and garden/Kioti dealer to ask them to test it. Counter person looks at me like I'm nuts. "Test it?". Yes, test it. She takes it back in back and comes back 5 minutes later and says, "It spins, but probably not the way you want it to. Maybe you should clean it."

Can you get me a price on a new one?
"What kind of tractor is it out of?"
A Power Trac PT425.
"That's not on my list."
I figured that, its a Kohler CH25S engine.
"What model engine is that?"
A Kohler CH25S.
"I don't have anything for that."
There's a Kohler part # right here on the starter.
"I don't think that's a part #."
Can you just look in a service manual for a Kohler CH25S and get the part # for a starter?
"I don't have a service manual."
I'll bet your mechanic does (This is a HUGE dealership).
"Well I don't."
Please just look up this number from the starter.
"It doesn't come back with anything."
Can I talk to your mechanic?
Guy in back of the counter comes up, asks what's going on. I tell him I need a price on this starter. He points at the part # on the starter and has the lady punch it into the computer.
"See, nothing comes up" she says.
"See that note that says "Part number has changed?" he says.
"Its a new part number" he says.
"$257.00" she says and give me the stink eye.

No thanks. And I drive to the other side of town to a small engine shop. He looks at it, pops the # in his system. $227 for genuine Kohler. $155 for aftermarket. $155 it is. Thanks! :rolleyes:

Anyhow, no tractor for me for 3-4 business days. :(

do those use a seperate bendix?

Ditto on being flabergasted that people can't lookup without a specific application...

Customer service seems to be a challenging concept for many people these days.

Online seems to be a chunk cheaper $70. KOHLER 25 098 11-S STARTER MOTOR OEM is still $135-ish.

Good luck.

All the best, Peter

yup.. mower spindles are almost 2x at my local dealer vs say.. amazon..

I was looking at that one, but it doesn't look exactly like mine. I'll find out what I get on Friday, hopefully.

Well my 4-5 business days turned into about 20 hours! :thumbsup:

Got the starter. It doesn't look like mine. It looks like the one for <$80. Bummer. However, it fits, it works and the tractor starts up just fine now, so barring rain, I get to haul logs on Friday. Woo Hoo!! :cool2:

Lucky you! :)

I was pretty happy with how easy it goes in and out. One nut for the 4 wires and two bolts to hold the starter on. Pretty easy access on the side of the engine. Its a 10 minute job to swap it out.

Now I'm wondering if I can rebuild the one I took out, or just toss it? Nothing urgent. Don't know if its worth rebuilding if it only $80-150 to replace it. Something for me to think about.

If its in hand, I'd sure take a look. If you can rebuild it for 35$ of brushes, lube and sandpaper/hacksaw time.. Might be a good spare.

Dear MR,

Have a look, but since it died by spinning and not engaging, the odds are on a broken spring (doable) or a bad gear (not so doable) or a bad winding (really not doable, at least in my book.)

All the best,

Peter

Attempted to start the PT425 with new aftermarket starter at 2F the other day. It cranked, but just not fast enough. Almost but not quite. Just a couple coughs out of the engine. Put a battery booster on it and it fired right up. So, not sure if the aftermarket starter is a little weak or not. Anyhow, two minutes and I was good to go.

Or maybe your battery is just a little weak.

If the solenoid clicked over than it clearly isn't an ignition switch/connecting wire problem.

After my 12 year old crummy battery charger fried my battery (somehow it clicked over to the "50A starter mode" and stayed there... even though the selector switch was on the "2 Amp" position... when I went out in the morning, the battery was boiled dry and almost melting... lucky it didn't catch fire), I bought a new Sear Gold Diehard lawn battery. Way better then the one I had in there... but it might just have been that the battery was old...

Battery is in good shape. Just cold and a different starter, I believe. Maybe over the summer I'll dismantle the factory starter it replaced and see if its repairable. It would be nice to have a spare on the cheap.

Yesterday I had a similar situation with my 422 it was about 15 degrees and I attempted to start and it would sputter some and then on the third attempt it fired up. I left it idle awhile then took it up over the hill to get some firewood. Last year I got one of those katz heaters to put on it but I never got around to putting it on, I may have to if it stays as cold as it has been the last several days (highs less than16 degrees and lows around 5.
