How to Repair a Crankshaft Seal with the Timing Case Cover Still Installed on Jeep Cherokee?

When servicing and fixing the front crankshaft seal with the timing case cover fitted, cut off the negative cable from the battery, then remove the serpentine belt, vibration damper and radiator shroud. Remove the oil seal very carefully so that the seal bore does not become dirty. When installing, line up the seal's open end with the Timing Case Cover Alignment and Seal Installation Tool 6139, apply a thin coating of Perfect Seal or the like to the seal's outside and rub engine oil around the crankshaft. Subsequently, fit the tool over the hole in the crankshaft and insert the draw screw tool into Seal Installation Tool 6139, tighten the nut firmly against it until the tool is even with the cover. Once the tools are removed, lightly coat the vibration damper hub contact surface of the seal with engine oil. Apply Mopar Silicone Rubber Adhesive Sealant to the keyway of the crankshaft and put in the key. After that, fit the vibration damper, tighten the washer and secure the bolt by screwing it on 108 Nm (80 ft. lbs.). Replace the serpentine belt so it is snug, fit the radiator shroud and link the negative cable back to the battery.

How to Replace a Crankshaft Seal on Jeep Wrangler?

To do the rear crankshaft oil seal service, you need to take out the transmission and the flex plate first. Insert a 3/16 flat bladed screwdriver between the metal case and dust lip, without letting the blade come into contact with the seal surface, but touching the crankshaft edge is fine. If you find tiny burrs or scratches on the crankshaft edge, smooth them out with 400 grit sandpaper to make sure the seal is not damaged when you fit it. Rub engine oil on the crankshaft flange and then fit Special Tool 6926-1 Seal Guide onto the crankshaft. Make sure the seal covers the guide tool, making sure the sealing lip points towards the crankcase. Push the seal into the block, using tool 6926-2 and stop once the tool hits the block smoothly. After that, secure the flex plate using Mopar Lock & Seal Adhesive on the threads and tighten the bolts to 95 Nm (70 ft. lbs.), followed by placing the transmission back in place.

Jeep Crankshaft Seal Parts and Q&A

Rear Main Seal
33004143
Q: How to Repair a Crankshaft Seal with the Timing Case Cover Still Installed on Jeep Cherokee?
A:
When servicing and fixing the front crankshaft seal with the timing case cover fitted, cut off the negative cable from the battery, then remove the serpentine belt, vibration damper and radiator shroud. Remove the oil seal very carefully so that the seal bore does not become dirty. When installing, line up the seal's open end with the Timing Case Cover Alignment and Seal Installation Tool 6139, apply a thin coating of Perfect Seal or the like to the seal's outside and rub engine oil around the crankshaft. Subsequently, fit the tool over the hole in the crankshaft and insert the draw screw tool into Seal Installation Tool 6139, tighten the nut firmly against it until the tool is even with the cover. Once the tools are removed, lightly coat the vibration damper hub contact surface of the seal with engine oil. Apply Mopar Silicone Rubber Adhesive Sealant to the keyway of the crankshaft and put in the key. After that, fit the vibration damper, tighten the washer and secure the bolt by screwing it on 108 Nm (80 ft. lbs.). Replace the serpentine belt so it is snug, fit the radiator shroud and link the negative cable back to the battery.
Rear Main Seal
4621939AB
Q: How to Replace a Crankshaft Seal on Jeep Wrangler?
A:
To do the rear crankshaft oil seal service, you need to take out the transmission and the flex plate first. Insert a 3/16 flat bladed screwdriver between the metal case and dust lip, without letting the blade come into contact with the seal surface, but touching the crankshaft edge is fine. If you find tiny burrs or scratches on the crankshaft edge, smooth them out with 400 grit sandpaper to make sure the seal is not damaged when you fit it. Rub engine oil on the crankshaft flange and then fit Special Tool 6926-1 Seal Guide onto the crankshaft. Make sure the seal covers the guide tool, making sure the sealing lip points towards the crankcase. Push the seal into the block, using tool 6926-2 and stop once the tool hits the block smoothly. After that, secure the flex plate using Mopar Lock & Seal Adhesive on the threads and tighten the bolts to 95 Nm (70 ft. lbs.), followed by placing the transmission back in place.
