Fujimarca MC709 gear assembly, one of the most important parts on the machine. This gear assembly includes a preadjusted spring, gear, handles, and assembly housing. To replace this part, all you would need to do is unscrew the old gear out, apply machine grease to the new gear, and screw it right back in.
Signs that your gear may need to be replaced:
Tension is too loose. Ice does not shave consistently due to lack of pressure on the ice.
Tension too tight. Shaft is hard to raise and lower, Ice shatters before completely used.
Grinding noise inside machine. Gear may me chipped due to age.
