Replace SMI Oscillator

The aim is to restore the accurate and reliable operation of the SMI system by replacing a faulty, worn, or malfunctioning oscillator. This maintenance activity helps ensure proper signal generation and system performance, reducing the risk of operational disruptions, inaccurate readings, or equipment failure.

remove and replace SMI oscillator

ensure power is off to the gun
trace wire from oscillator to power box
unwire from box and remove free wire from any wire wrap to oscillator
remove the bolts holding the oscillator arm from oscillator
unbolt oscillator from yolk
bolt the new oscillator to the yolk
bolt the oscillator arm back onto the oscilaltor
rewire to the box in the same place it was originally removed and rewrap wire
repower and test functions
