Vandercook 320G not staying engaged in Print

Hi. I’m hoping someone here can help me figure this out!

I am printing on a Vandercook 320G, and I’m having trouble with it staying engaged in PRINT. Is it possible to over oil it? The bar that runs in front of the cylinder that rotates as it engages into print, (sorry I don’t know the term for this bar) – it rotates back once I hit the form and thus not leaving the impression that I’m trying to achieve. I’m wondering if I’ve over oiled it and I can see a little oil seeping from around the end of the bar.

Would the cold weather have any impact? I’m keeping it in my garage in Canada, and it’s frikin’ cold, but I heat up the garage when I need to use it.

Any advice?

Thanks in advance!
Amanda

    It’s more likely that there is a lag or obstruction in the linkage of the cylinder trip rack assembly. Following the linkage backward: on the nonoperator’s end of the bar (rod), which should shift the impression cylinder into print mode, is a gear. This gear rotates when the verticle trip rack rises. At the bottom of the trip rack is a roller (cam follower) that rides up a cam (trip wedge). The initial position of the trip wedge is manually set by the print trip lever. Continue to inspect the linkage from the trip wedge back to the lever on the operator’s side.
