  Q: How to replace the front crankshaft oil seal with the timing chain cover in place on Lincoln Mark VII Overhead valve (OHV)engines?

  A: First of all, to replace the front Crankshaft Seal with the timing chain cover in place, remove the fan shroud, fan/clutch assembly, and drive belts. Extract the crankshaft bolt, and use a puller to detach the vibration damper. Care should be taken not to damage the cover or seal bore as you remove it using a special tool or a chisel and hammer. Inspect for any damage. Use a special tool or a socket and hammer to install the new seal. For engines with the timing chain cover removed, drive out the seal, clean the bore, and install the new seal with a socket and hammer. The procedure for rear main oil seals differs depending on whether one-piece or two-piece seals are used. To replace a one-piece seal, you need to take out the transmission, drive plate, and rear cover plate first. Remove this old one by prying off carefully then clean up back in there before applying both oil and grease on a new one that is pressed in place.

  Q: How do you replace the front and rear seals on an engine on Lincoln Mark VII Overhead cam (OHC) engine?

  A: To change the front seal, you'll have to take out the fan/clutch assembly; the fan shroud and drivebelt; the crankshaft pulley/vibration damper, and finally remove the old front Crankshaft Seal with care. Inspect for damage. It comes in with the open side facing in, lubricate it with engine oil, and drive it into the bore. Lubricate the lip of the seal, and install the damper onto the crankshaft paying attention to its alignment with the Woodruff key. Tighten up this bolt on a damper, put back the fan/clutch assembly and shroud, and restore a drive belt. To replace the rear seal, disconnect the battery cable, remove the drain plate then the back cover plate or backup housing. Remove the retaining ring or snap ring and discard the gasket material or old sealer.
