so i got it all apart except for the pto side crankshaft bearing. i want to take it out so i can clean teh block up real well and clean that bearing up good. i had alot of crudd floating around in teh block. the bearing seems to rotate fine and then kinda hangs up a little. like there may be something in the way. i want to clean it up good re-oil and check it out. how do these things come out. i dont see a way to get anything in on the side of the race like pushing out a regular bearing. it looks like i have to actually push on the center part on the bearing putting force on the balls. is this acceptable. it looks like that is how the factory tool does it from the kohler manual, from what i can tell. if that is how it has to be done i guess i will turn down some aluminum to fit bearing so i have somthing good to push against. i havent got the aluminum off the crank yet. i tried some easy off cleaner, but that didnt look like it did much. i have some draino gell too that i see people use. i dont have any muratic acid right now so im going with what i have and what others have said works well for them. ive had alot of stuff rust in the vicinity of the acid too. while i am rebuilding this think i think i will do a little tweeking, if it wont affect reliability. nothing major. smooth out the intake and exhaust ports. might mill the deck down to give a higher compression. just some stuff that kirt had on his website. i dont want to go crazy since this is my main mower. would doing anything like above hamper the reliability of the motor. the only real main thing would be shaving down the head.
