Brunswick A indexing problem

[Norcaltim]

I have one machine (straight a), that intermittenly double indexes. The result is I do not load the nine pin, it's always the nine pin & it does if about 20 percent of the time, any suggestions ?

If it is passint the 9 pin only...either your turret is not locking at the 5 pin center chute.(check your indexing latch adjustment).

It is also possible that your short turret belt is stretched,if this belt is streched the pinsetter runs fine but will almost always double index after the spoons unlock and cause indexing past the 9.

For whatever it is worth, we have a double index everynow and then and sometimes it is because there are loose bolts on the underside of the turret. Good luck.

You might want to check your time delay gear also. If the stop on the bottom of the gear and the stop on the trip latch don't make good contact, the gear can sometimes take an extra turn. If the latch isn't making enough contact, or the contact patch is worn, sometimes taking a little rubber off the latch bumper can cure the problem.

I Believe that Ar Rar is in the right area. Check the time delay gear for a bind. When the knob depresses the bearing connected to the "C" lever for 5 pin indexing, I have seen where that will either stop or go very slow and cause the turret to go past the 9. Usually either a dry or cracked bronze bearing on the gear.

Check the index cam on the bottom of the turret ring. Since you have "A's" yours should be a cast cam and they have to get really loose before they move down, but it does happen.
