Help removing gear cam housing…

Hey guys,

I am greener than green when it comes to letterpress, but am learning more and more each day. In am in the process of bring a soulful C&P 10x15 back to printing life and have a few questions.

I want to remove the large gear cam housing (RED arrow) to be able to remove the old, hardened grease from the cams, and re-grease them, as well to inspect the key(BLUE arrow) for the small gear to make sure it hasn’t come loose and has any slop in it. The housing looks like it is attached in two places, both easy to remove the bolt/screw.

My question is: I will have to remove the bolt holding the side arm on (GREEN) arrow. Is there anything special I need to know about these areas before the wrench touches her? Thinking about the white lithium grease for the gears. Any thoughts?

Also, not sure what the tapped holes are for on top of the cam housing are for? (YELLOW arrows)

Thanks in advance for any help!

Adios,
Aaron

Not sure why image didn’t attach:

Take out the special characters in the image filename (no ampersands, etc.)

Thank you dicharry!

The side arm will need to come off as will the drive pulley on the shaft. There’s a second bolt fastening the side arm at the rear shaft of the pres.

There’s nothing special to be aware of, but you should close the press (and keep it closed) during this procedure. You don’t really want to be opening the press with only one side arm attached.

Hope this helps. Let us know how it goes.

Brad.

Thanks Brad. I have removed the platen, so would I still need to close the press?

I also noticed last night that the fly wheel seems to have a heavy spot to help facilitate rotation maybe? Is this beast mechanically timed?

In most cases, the weight on the flywheel should be timed to be going from just beyond top dead center away from you as the press goes on impression, just a little extra oomph at the time of impression.

Thanks jhenry, makes sense to have the extra mass pushing at the end!

I was just a little surprised at how well engineered these machines are, and how simple they look from the outside.

Adios,
Aaron
