Piece fell off my press

Help! I took my rollers off to clean and I heard a pling, and this piece hit the floor. Without it in place the arms don’t rotate. Can anyone tell me what part of the press it belongs to? Thanks so much for your insight! I hope it’s not broken : ( It’s 2-1/2 inches long. C&P 8x10 - new style

I’m looking at the cp-newseries-parts-list and the closest thing is the rocker lock??

This is a locking devise that secures a rotating part on a shaft. It could have come from any number of rotating pieces. Check you flywheel, gears, etc. The irony is that when we want to remove them they can be very difficult to extract. When you find the home for this part be certain that alignment hasn’t been lost and tap it gently back in place.

Thank you. I’ll post again when i find it and replace it! revisting the drawings, and found something called 13K Pinion key and i think it might go on the 47 Side Arm towards the front of the press near the large gear cam wheel.

make sure the key fits in the cut out on the shaft and there is a matching cut out on the gear, you should be just fine.

That is the pinion gear key. It locks the pinion gear onto the flywheel shaft. If it fell off the press, then the press isn’t closing even if the flywheel is spinning.

There are matching grooves cut into both the pinion gear and the shaft. Just line them up and tap the key into place, holding the pinion gear aligned with the large gear. This is all on the right side of the press as you stand in front of the delivery table.

Might be stating the obvious (which apparently isnt that obvious) as the key takes a lot of thrust, in rotary fashion and as it is tapered in one plane only and will end up tight top to bottom, and achieve (initially) the desired result, but as the wear will be left to right, as well, in rotary fashion, would it not make sense to see how much wear or how many thou slack there is side play, (which must bear the brunt of the thrust, under operating conditions) and seriously consider making by hand, a new oversize key with a good 90 degree lug at the end for future extraction, whats left of the original, was dead about 50 years ago.!!! Possibly think in terms of how much power, has been transmitted by one little key, over many years, and how small?1/4 of an inch by 1/4 of an inch at best, and how long does it need to carry on, especially in these times, when embossing and die cutting, seem to be the order of the day.

I mean, whaaat?!

Whaaat?!? As Michael Winner, would say “CALM DOWN DEAR, ITS ONLY A COMMERCIAL, re checking the fit, look at the pictures carefully, of course it will be slack in the slot, look at the tram lines, at the base of the key into the shaft, and instead of just re inserting, solve the problem permanently as already described, so when you see the posts i.e. check for fit? end of story, NO, take the original posts on board, and finish the equation, or do it all again some time later. Its almost a racing certainty, that if you put it back slack, in the direction of thrust, it will not last anywhere near as long as original. Perhaps think in terms of how much power=thrust has that one little key transmitted?in its life time, on hundreds, thousands, maybe even millions of impressions, at least give it a fighting chance of finishing the race, without further hurt, to the shaft or the pulley/cog, the reason even tiny keys work so well/so long is because they are completely entombed on 4 faces, and cannot chatter, under power!?!?!?

Thanks to all for the help. The pinion gear key is securely in it’s proper place (see Arie’s comment) and all is right with the world again! : )

I’m so grateful for this forum.

Glad to hear all is right with the world…I’ve been having my doubts lately.

You may wish to inspect the key regularly for a while; I’ve seen them wiggle out periodically on their own. Easier to tap them back into place before they fall out.
