Random 180

[JAW]

So recently lane 21 has decided to develop an issue, pins drop into deck turret advances but machine stays at 180. Did the obvious 180 stop adjustment and it resolves the problem.... For a few games anyway then we go Right back to stopping at 180 any thoughts on what could be knocking it out of adjustment

There are two clamps on the turret/gearbox interlock.
One is directly under the cross conveyor, inside the turret frame (this is probably the one you are adjusting).
The other is at the end of the shaft, on the other side of the gearbox, where the 180 link connects (this clamp is probably loose).

Make sure the long link is not getting unlocked at 90 degrees.

Make sure the long link is not getting unlocked at 90 degrees.

That would also make the machine force double dumps.

Senior moment!

If the bearing on the clutch lever is going bad(rough or crusty) it can make the 180 link adjustment more critical(sensitive) because of the 180 link spring having to over power the "bind" instead of just pushing stop arm back.
