Remove the knurled nut, spring, and pressure plate. The felt pad is retained by a spring pin, which can be difficult to remove if there is significant dirt built-up. If the pin is relatively loose, a 5/32 Allen wrench can be used to drive it out. If the pin is difficult to remove, it can be driven through using a pin punch. Remove the pin to free the felt pad. Clean the pad as necessary and replace it when worn. The pad can be cleaned with a spray degreaser like 409 or a degreasing dish detergent to keep it clean. Apply the degreaser, rub it in with a cloth to remove any oil, wipe it off and clean it with a paper towel, and rub it dry. Let the pad fully air dry before reinstalling. This should be done once a year if film is run infrequently. Always stock spare felt pads so that a worn pad can be replaced immediately. | ||
Clean the spring pin, pressure plate, and clutch plate, and check for wear. If the pressure plate is worn, it can be flipped to use the other side. If the clutch plate worn or pitted, super fine steel wool (#0000) can be used to smooth down the plate. | Clean the spring pin, pressure plate, and clutch plate, and check for wear.
