How to install a new rear crankshaft seal during a complete engine overhaul in 4.8L, 5.3L, 6.0L V8 engine on Chevrolet Express?

If you're installing a new rear Crankshaft Seal during a complete engine overhaul, begin by removing the transmission. Next, take out the driveplate. Carefully pry the Crankshaft Seal from the rear cover using a screwdriver, ensuring not to nick or scratch the crankshaft or the seal bore. Note how far the old seal is recessed into the housing bore for proper installation depth of the new seal. Clean the seal bore in the block thoroughly with a shop towel, removing all traces of oil and dirt. Lubricate the outside diameter of the new seal and install it over the end of the crankshaft, ensuring the lip points toward the engine. Ideally, use a seal installation tool to press the new seal into place; if unavailable, a large socket can be used to drive the seal squarely into the bore and flush with the rear cover. Finally, reinstall the driveplate and then the transmission.

Chevrolet Express Crankshaft Seal

The Chevrolet Express Crankshaft Seal is intended to protect the front of the engine by locking in the oil inside the crankcase and keeping the moving parts of the engine slick and protected. Formed from a substantial combination of metal backing and molded rubber lip, this Crankshaft Seal grips the rotating crankshaft while hugging the timing cover, allowing no escape for oil when the van idles in traffic or pulls heavy cargo. Over the course of years of heat cycles and high mileage, the seal can harden, shrink, or tear. The driver may first notice drip marks under the nose of the Chevrolet, pooled oil around the harmonic balancer, or a sudden drop on the dipstick. When those clues show up, installation of a fresh Crankshaft Seal stops leaks, restores proper lubrication pressure, and prevents dry bearing damage that can ruin an otherwise reliable Express drivetrain. Earlier generations relied on a single spring-loaded lip style, but better designs of dual lip seals were introduced. The inner lip holds the oil in while the outer rim prevents dust and road splash. The modern Crankshaft Seal has a longer life and is more reliable for every Express on the road. Regardless of vintage, replacement of the Crankshaft Seal at the first sign of seepage helps any Chevrolet owner avoid bigger repairs and keep their van running smoothly.

Each OEM Chevrolet Express Crankshaft Seal we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.

Q: How to install a new rear crankshaft seal during a complete engine overhaul in 4.8L, 5.3L, 6.0L V8 engine on Chevrolet Express?
A:
If you're installing a new rear Crankshaft Seal during a complete engine overhaul, begin by removing the transmission. Next, take out the driveplate. Carefully pry the Crankshaft Seal from the rear cover using a screwdriver, ensuring not to nick or scratch the crankshaft or the seal bore. Note how far the old seal is recessed into the housing bore for proper installation depth of the new seal. Clean the seal bore in the block thoroughly with a shop towel, removing all traces of oil and dirt. Lubricate the outside diameter of the new seal and install it over the end of the crankshaft, ensuring the lip points toward the engine. Ideally, use a seal installation tool to press the new seal into place; if unavailable, a large socket can be used to drive the seal squarely into the bore and flush with the rear cover. Finally, reinstall the driveplate and then the transmission.
