Hi Kelvin, Although this won't help with the Triotar, you might consider in the future if you can "lighten up" an old helicoid by carefully working some light oil or solvent/oil combination into it. As you probably know, grease consists of oil in a soap-like base. With time, the oil separates from the base and leaves a heavy sludge of dried base in the joint. Sometimes, you can rejuvenate the base somewhat by applying a light oil and working the parts back and forth to stir the oil into the sludge, using Q-tips to remove any excess that appears. Even if the result isn't perfect, it's often satisfactory.
