I am in Memphis cleaning & repairing two Vandercooks, a 4 and a Uni III. The operator of the III tells me the motor jumps (or rather jolts) itself randomly during a press run and there appears to be a little bit of slack in the chain. I tested it out and sure enough it happened for me while I had the press on cycle & run modes. Having experience this problem myself while similar presses power Universals I always lessened the problem (if not got rid of it entirely) by adjusting the carriage speed and/or making sure my ink wasn’t drying out on press.
Since there’s a wee bit of slack in the chain this Uni’s operator is suggesting that I shorten the chain. My feeling is it has something to do with the clutch and that shorten the chain will be a headache and a waste of time, or worse . . . it’ll do some damage to the press. Anyhow . . . is there anyone out there with some experience with these Universal clutch adjustments and/or jumpy, jolty motors? I’d appreciate any input as I have a couple more days of work here cleaning, cleaning, cleaning.
Also, while I have your attention . . . the 4 is in need of a few parts. I’ve identified all the parts this school will need, but I am without a good reference to the small parts inside the inking rollers (the thin tubes in front and behind the oscillating cylinder). These are small collars (wood? plastic? I’ve never been sure. I had two pair made a local machine shop for m old 4 years ago.) that fit around the inking system roller frame and keep the inking rollers from slopping around and hurting themselves. Anyone have a good reference for these parts?
