The Mercury Crankshaft connects the thrust of the piston to the smooth spinning torque transforming the explosive upstart to a fine spinning that supplies flywheel and eventually propels the vehicle. Besides the rotating heart, Mercury engines established a civility image on bumpy tarmac. Weaker spring rates with stronger sway control maintained the level of the body when swallowing potholes. The cabins came with more insulation thus ensuring that the conversation remained effortless even as the speedometer increased. The steering is light but direct and drivers are always confident without struggling to arm wrestle the steering wheel. Seats provided wide cushions and supportive bolsters that rejected long distance weariness. Clear gauges and simple switchgear were employed in instrument panels to ensure that the eyes remained on the road rather than trying to figure out which buttons to press. Flexibility also was important and nickel infused blocks were resistant to heat cycles and corrosion. The combination of honest value and plush comfort that each Mercury balanced together appealed to the families who could not lose the spark of personality. The installation of a new Crankshaft starts with polishing block journals bright with a brush after application of assembly lube so that metal does not dry up. Install fresh main bearers, thrust washers, position the shaft on them and rotate it by hand to experience the drag. Install primary caps, then tighten in that order, followed by three step tightening to the figure indicated in the Mercury manual. Check endplay-blade gauge, roll the Crankshaft once more, ensure the smooth travel. Apply the oil seal lips, press the back main seal, position the timing sprocket, turn the Crankshaft one more time, fasten up the pan, and believe that this Mercury is going to bark to life.
