I've recently picked up a new customer who wants me to start servicing their machines. Since they need me to do the work on weekends I stopped in today to coordinate things for this coming weekend. They had been having a few other small issues they wanted me to address too, so we walked out to look at the machine.
While standing by the attachment I happened to look down and see something that didn't look quite right. What I saw was the tail end of a hydraulic cylinder was actually setting on the pin bosses which were, in turn, wearing into the tail end of the cylinder. Turns out that they had parked the machine near a nest of 'grease worms' awhile back and they decided to make a new nest in the tail end of the cylinder. I don't know exactly how long they lived there, but they took a 2 1/2" diameter pin and ate enough out of the middle of it that it's now only 1 5/8 diameter. It's amazing how much material those little critters can eat over the course of their lives.
Here is a pic of the pin.....Thought ya'll might enjoy seeing it. Thankfully the 'grease worms' ate nothing but the pin and the bushing in the end of the cylinder so the hole in the cylinder isn't egged. Unfortunately the bushing had spun in the bore so much that it's still oversized by nearly .040, so I've still got to weld it up and rebore it back to spec.
Hopefully I can come up with a new hardened pin and bushing from the OEM for Saturday delievery so I can have my customer back in operation by Monday morning. If not I guess a BIG company stands to lose a BIG amount of money until their machine is back in operation.....
The moral of this story is never park your machine near a 'grease worm' nest. If you do find that you have no choice, a good grade of EP grease will satisfy their taste rather quickly so they won't eat the steel....IF you use the cheap stuff, the pics below show the results....LOL

Today's Featured Article - A Cautionary Tale - by Ian Minshull. In the early 1950s my father bought an Allis Chalmers B and I used it for all the row crop work with the mangolds and potatoes, rolling and the haymaking on our farm. The farm and the Allis were sold and I have spent a lifetime working on farms throughout the country. I promised myself that one day I would own an Allis. That time event
