Drive Shaft And Switch Cluster - Brunswick StringPin Service Manual

Drive Shaft and Switch Cluster

The pinsetter uses a 3-phase motor and V-belt to run the string wagon drive gear and shaft. A cam and
switch cluster located at the opposite end of the drive shaft determines the location of the string wagon
by monitoring the rotation of the shaft. String guide fins mounted to the bottom of the frame keep the
strings separated to ensure they do not tangle or interfere with each other. Refer to Figure 2-14 and
Figure 2-15.
