Crankshaft Front Seal: Removal

WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed in this procedure. The crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction. For that reason, the crankshaft sprocket is also unfastened if the pulley bolt is loosened. Before any repair requiring loosening or removal of the crankshaft pulley bolt, the crankshaft and camshafts must be locked in place by the special service tools, otherwise severe engine damage can occur.
NOTE: During engine repair procedures, cleanliness is extremely important. All parts must be thoroughly cleaned and any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan, can cause engine failure.

  12. NOTE: The special tool will contact the crankshaft and prevent it from turning past TDC. However, the crankshaft can still be rotated in the counterclockwise direction. The crankshaft must remain at the TDC position during the crankshaft pulley removal and installation.
    NOTE: The engine front cover is removed from graphic for clarity.

    Rotate the crankshaft clockwise until it contacts the special tool. Use Special Service Tool: 303-507 Timing Peg, Crankshaft TDC.

  13. NOTE: The special tool is for camshaft alignment only. Using this tool to prevent engine rotation can result in engine damage.
    NOTE: The camshaft timing slots are offset. If the special tool cannot be installed, remove the special tool and rotate the crankshaft three-fourths of a revolution clockwise and repeat the previous 2 steps of this procedure.

  14. NOTE: The crankshaft must remain in the TDC position during removal of the pulley bolt or damage to the engine can occur. Therefore, the crankshaft pulley must be held in place with the Strap Wrench and the bolt should be removed using an air impact wrench (1/2-in drive minimum).
    NOTE: The crankshaft sprocket diamond washer may come off with the crankshaft pulley.

    Using a strap wrench, remove the bolt and the crankshaft pulley. Use the General Equipment: Strap Wrench

  15. NOTE: Early build engines are equipped with a diamond washer on each side of the crankshaft sprocket. Late build engines have a laser etched crankshaft sprocket and do NOT require diamond washers. If an early build engine requires crankshaft sprocket replacement, discard the diamond washers and the sprocket and install a new laser etched sprocket (service part). Diamond washers should NEVER be installed with the laser etched sprocket.

    If equipped, remove the diamond washer.
