Extensive cleaning needed to be done.  Grease buildup was increasing the friction between gears and affecting the bearings. In addition cleaning the gearbox contributed to the artistic portion of the clock. 

With the help of  Stephen Porter, R&D Engineer / UG Lab Manager at the University of California San Diego,  components that had worn out were machined and placed back into the gearbox.

 Pallets and the escape wheel experience stress during operation. The escape wheel's teeth exert pressure on the pallets as they engage and disengage, creating stress points on both components. This pressure is particularly pronounced during the impulse period, when the escape wheel transmits energy to the balance wheel.
