Start by removing the fan shroud, fan/clutch assembly, and drivebelts. Extract the bolt from the front of the crankshaft and use a puller to detach the vibration damper.

To replace the front seal, start by removing the fan/clutch assembly, fan shroud, and drivebelt. Proceed to remove the crankshaft pulley/vibration damper, and carefully extract the old front Crankshaft Seal using a seal removal tool or a screwdriver. Inspect the seal bore, crankshaft, and the seal contact surface on the vibration damper for any damage. Install the new seal with the open end facing in, lubricate its lip with clean engine oil, and drive it into the bore using a large socket and hammer. Subsequently, lubricate the lip of the seal and install the damper on the crankshaft, ensuring alignment with the Woodruff key. Tighten the damper bolt to the specified torque, reinstall the drivebelt, and put back the fan/clutch assembly and shroud. Finally, start the engine and check for leaks. For the rear seal replacement, disconnect the battery cable and remove the driveplate and rear cover plate. Remove the bolts and detach the seal retainer, then clean off any old gasket or sealant material from both the engine block and the seal retainer. Support the seal and retainer assembly on wood blocks, drive out the old seal with a chisel or punch, and drive in the new seal with a wood block or pipe. Clean the crankshaft and seal bore, lubricate with engine oil, and apply a small bead of ATV sealant. Install the oil seal retainer onto the crankshaft, working the seal onto the crankshaft with a smooth object. Tighten the retainer bolts to the specified torque, reinstall the engine rear cover plate, driveplate, and transmission. Complete the remaining steps in reverse, check the oil level, run the engine, and inspect for oil leaks.

To replace the front crankshaft seal with the timing chain cover in place, start by removing the fan shroud and the fan/clutch assembly, as well as the drivebelts. Extract the bolt from the front of the crankshaft and use a puller to detach the vibration damper. The crankshaft front seal can be removed using a special tool or, on most engines, with a small chisel and hammer, being cautious not to damage the cover or the seal bore. Apply penetrating oil if needed. Inspect the seal bore, crankshaft, and vibration damper for nicks and burrs. Install the new seal with the open end facing inward, using a special tool or a large socket and hammer. If installing a new vibration damper, ensure proper balance pin alignment and apply clean engine oil and RTV sealant. Install the damper on the crankshaft, aligning the keyway, and secure the remaining components. For engines with the timing chain cover removed, carefully drive the seal out using a punch or screwdriver, clean the bore, and install the new seal with a large socket and hammer. For the rear main oil seal, the procedure varies for one-piece and two-piece seals. For a one-piece seal, remove the transmission, detach the driveplate and rear cover plate, pry out the old seal, clean the crankshaft and seal bore, apply oil and grease to the new seal, and press it into the bore. Reinstall the components. For a two-piece seal, remove the oil pan, loosen main bearing cap bolts, and carefully install the upper and lower seal halves with proper protrusion. Apply RTV sealant, install the rear main bearing cap, and tighten the bolts. Complete the installation in reverse, fill the engine with oil and coolant, start the engine, and check for leaks.
