Hi folks,
Asking for some help! We are having issues with our gripper on our Vandercook SP-20 (serial number: 23442). The grippers were getting lower and lower and now do not really raise at all. The foot pedal was also pretty low to the floor, with us having to press harder on it for the grippers to open.
Tightened the bolt holding the foot pedal in place so that we can actually sort of press down on it again but now the pedal doesn’t come back up after being depressed.
Gripper stems were recently cleaned and grippers themselves move freely. The gripper cams are pretty gross and dirty and they aren’t making contact with the gripper stems… or at least not enough contact to raise them. Not sure how to get into the cylinder to clean the gripper cams. I’ve tried turning the gripper cams a bit… it did nothing.
Ordering a manual from Fritz. Saw some SP-15 people talking about turning the yoke but I’m not sure if that applies here.
The spring is X-7522. The same as for the Universal series.
FOUND IT! Broken spring! Anyone know the part #? Bottom left end connects to the foot pedal. Top right end connects to the outside on the opposite side of the cylinder.
Thanks, Paul, for your help!
Hey Paul,
Thanks for the thoughts. Gripper pins are in good condition, rotated them anyways for the heck of it – did not make a difference.
I’ll investigate your second thought. I think I might also have to get under the press itself ’cause I can’t make anything out through the hole in the shelving… We have a lift for litho stones though, so I’m sure we can figure it out… will update soon.
Welcoming any other thoughts now and always.
