pins do not drop sometimes

[eddieg]

Hey guys,
I have a machine that once in a great while all 10 pins will be in the turret and wont fall in, the probe is not contacting blocking fingers or anything. I just have to barely touch the 5 pin in the chute and they all release. Probably need to rebuild the release lever?

[Stripperbolt]

Yeah, I definately would be checking for any bind anywhere in the interlock probe and pin release lever. Bad bearings could cause the problem. Be sure to check the cam follower-type bearing that is on the spider ring. See if it's loose or maybe not rotating properly. Could cause the pin release lever to hang up. And check inside the 5 pin chute to see if there is any lip or whatever that could cause the base of the pin to hang on.

Since you said the probe is not touching the blocking fingers I would say you have a bind somewhere in the probe, connecting links, or the pin release lever. Could also be the capture roller for the pin release lever. I would suggest oil and inspect all of these points. Check for binding, something broken or missing or loose.

Sorry Stripperbolt, we were typing at the same time.

are the blocking fingers all the way up?

One more thing to check would be the indexing cam bolt directly opposite the pin release lever. It should be a button head bolt.

If someone has put a normal allen head bolt in there the 5 pin could 'hang up' on it.

He said the probe is not contacting the blocking fingers.

Spider not opening. Check the cam roller in front, might be frozen.

WAT HE SEAD

But this would not hold the 5 pin in the chute.

Great minds think alike.

Check the very bottom of the five pin chute, where the butt of the pin hits the chute when it is blocked by the lever. If it is dished out and shows cracks then the pin will hang on the edge of the flange that mounts the chute to the ring.

Check the bearing under the 5-pin chute release lever,
It may be loose, stiff, or froze up completely.

I took it apart today, looked like the tongue on the pin release lever was worn. It looked like someone grinded it down so the pin would not rest flat on it at times.

Someone may have shortened it at one time then ground it down.

Take a look at masternuts mod it's very helpful when working with release levers.
