cycling after the first ball

[Jr. Mechanic]

i have an A-2 that wants to cycle thru the second ball after the first ball is thrown, ex. guy throws a ball leaves the 10 pin, machine cycles to second ball then procedes to cycle yet again sweeping the spare and setting a full rack any ideas why? [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img] it doesnt do it all the time, does it once maybe every 200 frames...got me confused and my head mech in on vacation [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img]

Re: cycling after the first ball

The first thing that comes to mind is the 180 interlock adjustment. Sounds like it might be a little high. Does the turret drop a load of pins when this happens? If so, that is most likely the problem. When the turret drops the pins, the 180 lever will move upward. This action puts more pressure on the actuator link and can cause the gearbox to engage. So, try lowering the 180 lever a bit. Give it a try.

Bye for now,

I would get down there and check all 10 deck pads real close making sure none have holes. After verifying they are all OK then check your detector rod adjustment.

Re: cycling after the first ball

First thing I'd do is watch how the rake drops when it cycles at the wrong time ... fast=shotgun or cushion, slow=clutch mechanism

Clutch stuff:
I'd take a look at the gearbox clutch adjustment ...is the machine stopping high?

Is the clutch yoke running high enough that the stop lever gets back in easily?

Is the bumper worn out making the clutch latch not catch every time?

Shotgun:
Pop shotgun and cycle slowly until rake cam hits low dwell. Gun should latch/unlatch at low dwell with NO hesitation. With gun latched at low dwell, firmly smack rake cam follower arm forward with palm, gun should stay latched, if it opens, shaft in gun or other parts may be marginal.

Hope something here helps:

Things I have encountered.

Roller on reset lever not getting high enough to get under the latch. Check the bearing on the other end of the lever. Unfortunately, the best way to check the bearing is to pull the reset lever. A visual inspection will not do it, and you cannot touch it because it is too far down between the 1 to 1 cover and the mounting plate to get your fingers in there.

Speaking of the reset lever, there could also be a small crack where the bend is in the lever also not allowing the roller to get under the latch. If that's the case, replace the lever.

Here's a new one that I am encountering.

Check the trigger switch. The pin on the trigger switch mounting plate could be loose. The pin is like a rivet, and over time, the pin works loose from the lever being pushed down. This causes the lever to not be completely pulled away from the cherry switch. As the lever is pushed down, the switch momentarily breaks contact , and as it continues down, closes again. I just recently had this problem, and it drove me nuts. I replaced the trigger switch, and the problem went away. I have been replacing the original trigger switch with a dual mercury switch. Works great.

Re: cycling after the first ball

The every now and then odd cycling can be a pain to locate but try checking this.(1)cycle solenoid tilted twords the rear of pinsetter?,if so push it forward,have seen some lean rearward and thusly causes the latch to slip off and cycle.(2)Cushion links binding or try this too,how about the pin curtain mounting brackets,are they leaning twords the kickbacks?If so i have seen this trip a machine to cycle since they hit against the cushion linkage assy.support arms.Just something to look at beside the other goood odeas!

Re: cycling after the first ball

You might wanna check the spring that connects the reset lever to the clutch release lever. I've had this happen to me a couple of times(during league, of course.)

Just take your time putting a new one on if that's the problem. You could become very angry at the machine as it's not in a very easily accesable location. [img]/content/btubb/images/%%GRAEMLIN_URL%%/mad.gif[/img]
