And now for something just a little bit out of HEF's mainstream...
A friend of mine has an older Elgin Pelican street sweeper. I believe it's a Model S, although the one attached picture is of an SE, and they look pretty similar. (I found a good picture online, and took a screenshot.) The machine is handy in the development for keeping the neighborhood streets cleaned up, since pretty much every day something is tracking mud onto the pavement.
The gutter broom has ceased to turn under its own power.
We were troubleshooting it the other day, and it seems as if there might be a broken key on the shaft that drives the brooms. If you manually turn the gutter broom, you can see the chain moving, and the sprocket spinning on the shaft. The same shaft drives the main broom, and it turns and functions normally.
The picture shows the assembly at the end of the shaft (the "jackshaft bearing" according to the lubricaton chart). The red line represents the chain that's not working, and the green line represents the one that is. The two sprockets are pretty much side by side on the shaft.
What's not as visible in the picture are the two set screws on the sides, set 90 degrees apart. The two holes facing the camera do not seem to go all the way through the piece. There's a grease fitting in the center hole.
(Before I started composing this post, I sent myself a picture I took of the actual machine. It hasn't arrived yet. Snail email? I'll post it when it gets here.)
Can anybody confirm that there's a key that makes the sprocket turn with the shaft, and can anybody give a clue as to how to disassemble that part and get to the problem? (We called the dealer on Friday, and are still waiting for the service department to call back.)
Thanks in advance.
