    Its me again with another m head problem

    I replaced all the bearings in the head because of noise only to discover that the noise is worse.

    When I cut I get a loud rattling sound. I have narrowed it down to the female spline shaft that goes through the step pulley that drives the spindle.

    Does anyone know how to take the rattle out or where to get new drive spline shaft.

    I can understand your frustration and on top of that the time and money that went into it. Have you thought about getting a J head and selling the M to recoup some of your $. I know it’s hard to give up any toys that are acquired (believe me I know!), but the J head is sooooooo much better…Dave.

    I have thought about it

    I got the m for $750

    Put about $400 in it

    How much do you think I could sell it for?

    I would keep the new motor $150

    It's all pretty now with all the parts there

    You might try putting some fairly heavy grease like NLGI 2 on the spindle splines where they go through the pulley, and see if that helps to quiet it down...
