My post was related to industrial lubricants, but one shouldn't say "automotive" grease like it is a bad word because THEY ARE SOME OF THE BEST lubricants for shock load. Many E.P. greases fit either in the finest machinery or your old car. The hinge pin seems to wipe all lube away, but a thin film stays with a quality EP lubricant. Just a few thousandths of an inch or even less........ What we want to prevent is metal to metal contact! Oil will not do this adequately; especially light viscosity oil. Even more for our case is the angular, even torsional load the hinge pin sees in a side x side double firing first one barrel than the other. This has a tendency to "wallow" the pin fit rather than wear it evenly. We are talking clearance amounts one may see or not see with the naked eye. But a good E.P. will protect these high load spots. That is what our goal is! Some greases are better than others for "staying put" or remaining where you want them, where the action is. I have a rather un-scientific test for this "clinging" ability. Stick a finger into the grease a quarter inch or so. Pull away from the grease slowly and the grease should try to "string out" from the container to your finger. The best I have seen in this "clinging test" is a Chevron product called "Ultra-Duty EP" It is red in color and I have had it "string out" three feet or more in little red threads of grease! Chevron advertises that it "stays where you put it". I will say this is a true statement. Not only that, it has a Timken O.K. load of 70 . . . . . Big Rx |
