As of this week I am having a rash of interlocks developing throughout the house. I have been going to each lane that has had a problem and adjusted the sweep and table switches to correct them. Is this something that I should expect to run rampant throughout the house?

Re: Rash of interlocks
Sounds like you’re on the right track adjusting the cam switches first. Very important the sweep and table stop where they are supposed to.
The sweep stopping properly at first guard is usually the most important. If you can’t achieve this with cam adjustments so the sweep stops dead and consistent, you got coasting problems.
Most common coasting problems usually caused by:
Lower contacts (sweep/ table contactors) bad
Burnt (or loose)C1 pins
Weak or bad motor capacitors
Loose gearbox (or worn brushes for National motors)
Sticking centrifugal mechanisms
Cam switches going bad
Bad wire in motor plug

Re: Rash of interlocks
Cams and contacts are our biggest culprits for interlocks. 99/100 times when the cams get adjusted and new contacts are installed interlocks are byebyeAll I want in life is to turn wrenches and climb around pinsetters/pinspotters again :/

Re: Rash of interlocks
The rest of the story... elco chassis with single board conversion. General Electric motors with the centrifical switch bypassed by a start relay. Found one lane to basically come down to a start relay that was mildly burnt up, causing motor to coast a little bit. Other lane that I was having problems with I replaced the sweep shaft, both cams, as well as the start relay. Not sure which part on the sweep replacement fixed the problem, but sweep now comes to a dead stop at all guards and at zero.

Rake sweeping out of time, and pin launching onto lane.
