k241 flywheel removal / unexpected results

[rsshallop]

Hello, I tried removing the flywheel with a gear puller, but I fear I anchored the puller onto a part (cup assy, flywheel drive?) that is not part of the flywheel. Anyway, that unexpected part appears to also be threaded onto the crankshaft, which I am fairly sure is now damaged due to my use of the puller. I did remove the large nut on the crank beforehand, which I thought would be the last step before pulling off the flywheel. Your thoughts on how to recover from this (if possible) would be appreciated.

That cup isn't threaded but needs removed first before pulling the flywheel,likely broke the bottom out of the cup. The cup has a locator pin on the bottom which fits in a hole on the flywheel and can be a little stubborn to get off ! Try to get the piece out if that is what happened and soak the keyway with some penetrant , there should be two threaded holes for puller in flywheel that likely are crusted over with dirt ! good luck

Thanks athomas, OK, I think I see where the locator pin is located in the cup. I will soak everything in PB Blaster tonight, then I'll thread the nut back onto the crank and try to slowly push the cup back somewhat before trying to free the locator pin from the flywheel. I hope I am on the right track.

The pin is part of the cup and if the bottom of the cup is broke out the rest of the cup should be loose and free from the flywheel ? The pin locks the cup to the flywheel under the nut so it turns the driveshaft without slipping I believe is the only purpose it serves. If the bottom of the cup is broke out I don't believe it would prevent you from pulling the flywheel only from getting some penetrant back there on the keyway and shaft , or is it partially broke and stuck there ?

second thought I think the pin stays with the flywheel and fits in the hole in the bottom of the cup , had one apart a couple weeks ago and believe that's how it is ! Maybe someone that does more engines will chime in !

use a steering wheel puller to remove the flywheel.
Bolts thread into the flywheel itself.
Read the service manual, could have avoided this.

I've rotated the crank 360 degrees a few times inspecting the cup as it turns. If I am looking at where I am suppose to, then I don't see so much as a crack. Maybe dumb luck or maybe a hairline crack I haven't spotted.

went to garage and took pic of flywheel with cup off and flywheel side of cup ! You can see the pin with anti-seize on it and the hole in the cup !

Looks like cup is stuck on pin and possibly starting to break pin hole out of cup ? At this point try to tap it from back directly above the pin and work it off likely corroded on the pin .

athomas, Wow, thank you for taking the time to do that! I appreciate it. I do have the Blue ribbon Service manual GSS-1465-B in hardcopy and I did go over as much flywheel removal material for my Kohler while I was waiting for the puller to arrive in the mail. Granted, the drive cup has been staring me in the face all along and I never did see anything to suggest that I should try to remove the flywheel by anchoring the puller to the cup. Bad assumption on my part.

Normally the grass screen and cup need to come off together before the tin shroud can be removed , blow the dirt out of the puller holes prior to using them ,I usually run a tap in them and clean them up before bolting the puller on !
