Drive Wheel FAQ
You may need to remove the main (drive) wheel from your MACH or Echo for troubleshooting or repair. Here is how:
Remove the head and flyer from the wheel base
Locate the screw at the bottom of the hole where the head fits into the base.
Using a long phillips screwdriver, loosen the screw
Move the shaft forward and out thru an open treadle
Remove the main (drive) wheel
To replace the drive wheel on a Bee, King Bee, or Queen Bee:
Loosen the brass screw behind the wheel
Open the treadle
Push the shaft forward until the wheel is free
Several washers will fall out - keep these to put on with the new wheel as well as the wire ring.
Put the shaft into the new wheel
Add the wire ring to the shaft (next to the new wheel)
Then add the washers
Slide the wheel down into place
Push the shaft into the base
Tighten the bass screw to secure
Reinstall the Drive Band
The Wheel Wobble on the MACH 2 is due to the wheel shaft moving. Here is how to add a set screw to hold the shaft and keep the wheel from wobbling.
Purchase a wood screw at your local hardware
Use a small drill about 1/8" and drill a pilot hole about 1 1/2 " above the wheel shaft on the back (drill at an angle: that will hit the shaft at the halfway point about 1/2" in)
Screw in a #8 screw about 1 3/4 inch long - this will hit the shaft and lock it from moving. This will remove most of the wheel wobble.
