    Use the little black puller that came with your kit. Screw it into the sprocket, hold it with a wrench, and tighten the bolt with another wrench or socket. On some of my motors, I got the sprocket off by just pulling on it with my fingers.

    Hi, thanks for the reply. but what do you mean by black pulley?
    i used the tool that unscrews the spark plug to take out the center bolt of the sprocket, but from there, it seems to be tight in place,--so, after the center bolt is out, then what? thanks, please let me know some more details.

    You should have a small black puller included in your motor kit to remove the small (10 tooth) motor sprocket. It is approximately 1 inch in diamester by 1 1/4 inches long. If you don't have one, you will need to buy one from someone like thatsdax.com. If you look at some of the motor kits for sale on eBAY, you might be able to see one in the picture.

    The tool has two parts, the body has two different diameter threaded ends. The other part is the bolt, which can be inserted into either end of the body. The body is screwed into the receiver threads on the gear and then the bolt is threaded into the body, the bolt then pushes against the gear shaft which causes the gear to pull up off the shaft.

    Maybe this picture of the puller will help.

    Way too graphic for the youngsters, we hadn't even gotten to the stage of using the latin terms for everything.
  9. Dr. J.

    Dr. J. Guest

    Graphic...you have got to be joking! I suggest that you watch The Red Green Show on PBS and then maybe you can figure out the humor of the quote. Try laughing a little and even being a little silly, you will be surprised what an affect it will have on you!

    I will remove the quote from future postings so folks won't have to spend their time to make something out of nothing. Better yet...I won't post.

    methinks i spy a mis-understanding...yup, that's what it is, just a mis-understanding is all 8)

    Yes mis-understanding. "Remember we're all in this together."
    I was joking about the resorting to photographs, because all of our wasted words were failing to get the point across. :roll: Are we explaining this to Harold? Thus the "graphic" reference.

    pics belong in "technical help" & imo, someone shoulda posted a pic of the puller right off. anyway...

    and, we are all in this together, for the fun of it :)

    i've seen many mis-takes made about sarcasm & humor in a post, i fall for it myself sometimes, but i eventually manage to re-read the "episode" and see that it wasn't personal at all 8)

    I apologize truly, I was posting with the view point that we had done everything but go over to the guys house and demonstrate the " mystery tool". In my family the adults would use latin medical terms to keep the kids in the dark about what they were talking about. I am a fan of the Red Green Show and the folks at the Possum Lodge and my humor tends towards the obscure. This does not always come through translated to the internet, sorry. :D -Edward

    I haven't gotten to see the Red Green Show in decades!! I liked the one where he took the Cadillac and converted it to a DeLorean.

    Or when the community loaded the "historic one room schoolhouse", hoisted it on the back of 6 pickup trucks, half driving forward and the other three running in reverse. They had a guy on the roof to handle the electric lines, but somehow set the fire department building on fire.

    You can take the deadhead out of the concert, but you can't take the bootlegs out of the deadhead. A friend met Bobby Weir on an airplane flight, asked him to autograph a cassette she "happened" to be carrying in her purse. He asked her if it was a bootleg, and when she said "what else", he just smiled and signed it. THEN she said "Bobby, I've been living here three years, can't get NEW YEARS EVE tickets, and he gave her a number to call, his assistant. She had tix at will call.

    some of you may have noticed the glaring lack of a rules-list here, an unusual characteristic for a public messageboard...

    but, if i sed i know exactly what, where, and how, and perhaps in my past i may have stumbled across an unauthorized copy of this or that, would yas please understand that i'm not making any judgement at all, but only saying that the subject doesn't shine the most favorable light on our site-admin?

    please take that subject PM, 'k?
