    My kit came with a "screw tool" but there didn't seem to be any instructions on what to do with it. I got my motor installed and apparently didn't need it.

    Used for pulling drive sprocket, large clutch gear (tool is reversible), Make sure that the tool is bottomed out and secure, or it might (usually a problem) pull the threads either in the gear or tool. The tool is screwed into place then the center installed. As the center bolt/shaft is tightened and under pressure tap head with a hammer...continue, repeating procedure.
    Tool used if engine needs to be taken apart.

    One would think that Mr. Grubee would have sold enough of these $25.00 engines for $150.00 or $200.00 by now that he could afford to pay someone to write a comprehensive assembly and maintainance manual instead of the joke that comes with them now.

    nope...works the same, but it's the wrong size for crank arms.

    I do agree theres a huge need for a clear assembly manual , I've yet to see a novice do a good build using the supplied instructions .

    I should have taken some pics of the worst built attempts as a learning tool , seems the translation from Chinese to English manuel's are horrendous , when looking at many installs I felt like screaming , laughing & crying ~ Haaaaaaaaa'''

    and if you thought pushbikes were hard, try stepper motors and driver boards that need to be hooked up to a PC.... :sweatdrop:

    Thanks for the explanation of this tool. I hope I don't need it for a while.
