2. Remove the old V-belt.
3. Remove and discard the 4 pillow-block screws holding the crankshaft.
4. Remove and discard the old crankshaft assembly.
Install the New Crankshaft
1. The mounting surfaces must be flat before installing the new
assembly.
2.
Set the new crankshaft assembly onto the pillow-block mounting pads.
Facing the back of the machine, look at the V-groove balance-plate pulley. It
should be on your left. Adjust, if necessary.
3. Install the new crankshaft assembly with new washers, nuts and 7/16-14” hex
screws. Drop these into position, but do not tighten at this time.
4. Align the pillow blocks over the crankshaft mount. It may be necessary
to remove the motor in order to align, then tighten, the screws on the
crankshaft. If so, follow these steps:
• Lift the front of the machine with the 2” x 4’ wooden board and place the
blocks under the board.
• Remove the 4 hold-down screws on the motor.
• Move the motor out of the way.
5. Align the crankshaft assembly assuring that it is parallel to the rear surface
of the inner frame. Measure the distance between the inner frame weights
and the rear edge of the crankshaft. The measurement on each side of the
crankshaft should be the same.
6. First tighten the front nuts and screws; then tighten the others.
7. Remove the old motor pulley with a hex wrench and a wheel puller.
8. Install the new pulley using the old square key. Do not tighten the pulley set
screw at this time.
9. Reinstall the motor, if it was moved.
