After discovering that the helical gear in our gearbox was damaged, we also found the PINION SHAFT to be severely damaged as well. This had to match with the helical gear's teeth so the machine shop had to fabricate a new 2" diameter pinion shaft for us.

Total downtime to have both gears fabricated was about three weeks because of the steel hardening process that was involved. This affected production schedules and cost us a lot of money, not including the cost of fabrication. We decided to increase frequency of periodic maintenance shutdowns to avoid major problems like these in the future.
