Hotpoint timer stalls in middle of opperation

I’m having an issue with the timer stalling during operation. It will get to a certain point and stop moving. The washer will stick in that mode. I can manually progress the cycle by hand, it will still go through all the cycles, just not on it’s own. Just needing opinions on if it will just be the gear, or the whole timer unit. Is there a way to confirm, if it’s the gear, will it have clear damage, broken tooth. I haven’t taken anything apart yet, just trying to get my ducks in a row before I start.

Thanks.

Fidofax, since the timer is hanging up in a cycle and there are no individual parts of the timer available separately, the timer would need to be replaced. GE WD21X10013 Timer (AP2039699) - AppliancePartsPros.com
