1992 Chevrolet Beretta Parts Questions & Experts Answers

• Q: How to install a rear crankshaft seal on 1992 Chevrolet Beretta?

  A: Clean the bore in the block/cap and the seal journal on the crankshaft. Check the crankshaft journal for scratches and nicks that could damage the new seal lip and cause oil leaks. If the crankshaft is damaged, the only alternative is a new or different crankshaft. Apply a light coat of engine oil or multi-purpose grease to the outer edge of the new seal. Lubricate the seal lip with moly-base grease or engine assembly lube. Press the new seal into place with the special tool, if available. The seal lip must face toward the front of the engine. If the special tool isn't available, carefully work the seal lip over the end of the crankshaft and tap the seal in with a hammer and blunt punch until it's seated in the bore. This engine is equipped with a one-piece seal that fits into a housing attached to the block. The crankshaft must be installed first and the main bearing caps bolted in place, then the new seal should be installed in the housing and the housing bolted to the block. Before installing the crankshaft, check the seal journal very carefully for scratches and nicks that could damage the new seal lip and cause oil leaks. If the crankshaft is damaged, the only alternative is a new or different crankshaft. The old seal can be removed from the housing with a hammer and punch by driving it out from the back side. Be sure to note how far it's recessed into the housing bore before removing it; the new seal will have to be recessed an equal amount. Be very careful not to scratch or otherwise damage the bore in the housing or oil leaks could develop. Make sure the housing is clean, then apply a thin coat of engine oil to the outer edge of the new seal. The seal must be pressed squarely into the housing bore. Work slowly and make sure the seal enters the bore squarely. The seal lips must be lubricated with multi-purpose grease or engine oil before the seal/housing is slipped over the crankshaft and bolted to the block. Use a new gasket-no sealant is required-and make sure the dowel pins are in place before installing the housing. Tighten the bolts a little at a time.
