This repair is on a Hayburners II, a 48 year old game made in 1968 by Williams. We had to work many extra hours to get this old girl running like a clock. This was not a difficult job, just a tedious long adventure in all the mechanical malfunctions caused by age and stagnation. The grease and oil on this game was stuck so hard the 4 stepper unit's shafts and bearings were frozen and had to be heated just to take them apart. The chimes needed new grommets, the flippers we worn out, the horse race unit was stuck. On that horse unit you must be carful not to get any oil on the slip clutches on each of the 6 horse drive shafts. This game has a 6 horse race unit and a cool moving shooter that alows you to aim the ball onto the playfield. The service notes sent to the customer follow:
