It pays to maintain your gudgeon pins in tip top condition, for otherwise your gudgeon pins may fail to operate smoothly or could become "un-pinned". This could lead to "flasking". The pins are easily located beside the wet-pinioned flange's journal-piece and should be inspected at regular intervals. Apply a few drops of proprietary lustralising agent or anti-coagulant flux, ensuring that it is well bedded in between the splines. Do NOT over-tighten the crux bolt. Check periodically for signs of seepage where the gaiters rub against the main rostrum on the "up" stroke. Wipe BOTH ends with a swatch of lint-free scrim, then use a strobe and calipered pargeting tool to check the inner tension. If EITHER the bezel or variable arm is thwarted or "tram-lining", switch OFF and replace the grommets without delay.
