Hello everyone.
1966 230SL. I have had the Oregon grease gun "Push n Lube" for probably a few years now, and just decided to use it. I don't believe that it is working, though. I hold it firmly against the "cup" in the hinge and pump the gun by pushing it into the cup repeatedly but it just doesn't look like anything is happening. There's no evidence of grease in the cup nor on the tip of the gun. I then took a socket small enough to force the cone of the tip against and tried to pump it there but nothing came out but I'm not sure that it would, i.e. it may be that the ball in the tip needs to be depressed to release the grease?
The grease in the gun looks perfectly fine. So I'm wondering if I might be missing something? What is your experience in greasing these hinges?
Thanks,
Harry
