1995 Jeep Wrangler Crankshaft Seal Parts Questions & Experts Answers

• Q: How to correctly install a crankshaft seal on 1995 Jeep Wrangler?

  A: Clean the bore in the block and the seal contact surface on the crankshaft, checking for scratches and nicks that could damage the new seal lip and cause oil leaks; if the crankshaft is damaged, a new or different crankshaft is necessary. Apply a light coat of engine oil or multi-purpose grease to the outer edge of the new seal and to the seal lip. Carefully work the seal lip over the end of the crankshaft and tap it in with a hammer and punch until seated in the bore, ensuring it is squarely positioned. Inspect the rear crankshaft seal bearing cap and engine block mating surfaces, as well as the seal grooves, for nicks, burrs, and scratches, removing any defects with a fine file or deburring tool. Install the semi-circular seal section in the block with the lip facing the front of the engine, then repeat the procedure for the other seal half in the rear crankshaft seal bearing cap. During the final installation of the crankshaft, after checking the main bearing oil clearances, apply a thin, even coat of anaerobic type gasket sealant to the chamfered areas of the cap or block, avoiding contact with the bearing face, crankshaft journal, seal ends, or seal lips, and lubricate the seal lips with multi-purpose grease or engine assembly lube. Use only a replacement rear crankshaft seal that includes a plastic alignment tool, as proper centering is not possible without it. Apply RTV sealant to the area where the seal cover will contact the oil pan surface, then apply a 1/4-inch bead of RTV sealant around the circumference of the seal retainer recess in the block. Install the seal and retainer over the crankshaft, ensuring the two dowels align with the seal retainer, and install the bolts without lightening them. Once the seal is fully against the crankshaft, remove the plastic alignment tool and tighten the bolts to the specified torque.
