Timing Belt and Motor Replacement: XAxis (continued)

Release the timing belt adjusting kit base screw

located on the rear of the Xaxis to loosen the

timing belt from the idler pulley. This loosens

the timing belt enough to remove it from the

idler and timing pulleys.

NOTE: The screw only needs to be loosened,

not completely removed.
