When I put the borrowed Tomar 3 disk clutch on my motor this weekend, the set key didn't go in all the way by hand, but I couldn't get it out. Thus, I had to screw the bolt into the crank to set it all the way...
Now I can't remove the clutch from the crank... So, what should I do? Somewhere in my stuff I actually own a gear/pulley puller, so I guess I need to find it? Anyone have this problem before? Suggestions?

I would get the opinion of the person whom lent you the clutch, as it is their clutch you would be potentially marring up with a gear puller.

yes... the key will lock the clutch in place if not properly fitted with a file.. A simple puller can be used to remove it. after removal, using a scotch brite pad and brake clean to remove fretting on shaft and apply anti seize compound (not to much, it will get into the linings and cause trouble) and filing the key down to fit snug but not tight will make removal much easier.

Dont use a "jaw" type puller... the ones that screw into the clutch itself work best.

And, yes, I agree that I should get the opinion of BradW who loaned it to me. In fact, I already mentioned to him what happened... However, my guess is that he would want me to research the options from the gurus who know, as neither he nor I are clutch removal gurus... BradW, what's your take on this? |

My take on this is getting clutches off when the key isn't fitted properly is it is a royal pain in the butt. One the theories as to why we were having motor issues initially was too much play in the keys. From then on I made sure my keys fit more snugly. The downside to that is sometimes they become too snug and are then a beotch to get off. The first time that happened I took my kart over to Todd's and he used this long old pry bar to get it off. The couple of times it happened after that I used the wooden handle of a mallet to basically pry it off being as careful as I could with the side cover.

Instead of a pry bar, I've used a tie rod puller (pickle fork) to lever the clutch off the shaft.
Or you could make a puller with some flat stock, all thread, nut, and two bolts.

OK, you guys who are willing to use pry bars scare me! I found my puller, pulled out 3 (every other one) of the 1/4 x 28 bolts (NOT the ones with the springs), went to hardware store, bought 3 long 1/4 x 28 bolts, used them with the puller, and popped the clutch right off...   |

And thats the way ya do it! Yea, I was automotive master technician most of my life working for many dealerships. Ive learned to use pry bars and hammers as precision instruments, please dont try that at home..  In other words, take your time fitting the clutch and use some anti seize and you will save some headaches here. |

Brad is right... the Key needs to fit well enough for the the clutch not to rotate back and forth on the shaft.. this means the key must be filed squarely at an angle to match clutch.. ie, Notice that the inside of the clutch keyway is cut at a slight angle.

I was trying to visualize what puller I was going to use on mine, I have several. But now I know. Thanks for posting pictures. I've had this puller most of my life, and used it with my dad on his cars when I was small. Thanks again.

Funny, Ron, I have had these pullers for almost 30 years, and it's been almost that long since I used them. The only reason I recall having them is that I took them out of my old tool box when I was setting up for karting. Looks like they are going back in the tool box!
