What is the correct part number for the main drive gear? Century MSA direct drive. Gear only.

Also be sure to check the mating steel gear for wear... if the steel gear is showing ANY wear pattern at all the new gear will not make it's useful life span.

It depends on the Main drive shaft.

If it is the older style ST-744 shaft (one-piece shaft with the large pulley adapter/flywheel), then you would need the GR-183 fiber gear.

If you have the current style multi-piece shaft (pulley adapter mounts to a straight shaft, and the pulley then mounts to the adapter) then you need a GR-328.

The difference is the inside-diameter of the gear...the current shaft is much larger.

The steel gear is the GR-182 regardless of main drive shaft.
