How to remove and reinstall a flywheel in 4.3L V6 engine on GMC Yukon?

Raise the vehicle and support it securely on jack stands, then remove the transmission. Mark the relationship between the driveplate and the crankshaft with a marker or similar device, then remove the bolts that secure the driveplate to the crankshaft. If the crankshaft turns, wedge a screwdriver in the ring gear teeth to jam the driveplate. Remove the driveplate from the crankshaft. Since the driveplate is fairly heavy, be sure to support it while removing the last bolt. Clean the driveplate to remove grease and oil. Inspect the surface for cracks, and check for cracked and broken ring gear teeth. Lay the driveplate on a flat surface to check for warpage. Clean and inspect the mating surfaces of the driveplate and the crankshaft. If the rear main oil seal is leaking, replace it before reinstalling the driveplate. Position the driveplate against the crankshaft. Be sure to align the marks made during removal. Note that some engines have an alignment dowel or staggered bolt holes to ensure correct installation. Before installing the bolts, apply thread locking compound to the threads and place the retaining ring (if equipped) in position on the driveplate. Wedge a screwdriver through the ring gear teeth to keep the driveplate from turning as you tighten the bolts to the torque specifications. If the transmission front pump seal/o-ring is leaking, now would be a very good time to replace it. The remainder of installation is the reverse of removal.

GMC Yukon Flywheel

GMC Yukon Flywheel balances engine pulses, stores rotational energy, and provides the starter ring gear and clutch surface so the SUV can launch easily. This Flywheel is bolted to the crankshaft and spins in unison with the engine. Its inertia smooths out the bursts of combustion, so the power feels even. The starter motor will mesh with the Flywheel ring gear when the ignition key is rotated. This will turn the crank until the engine fires. As this happens, an overrunning clutch uncouples the motor. When the clutch disc grips the face of the Flywheel during driving, power is transmitted via the GMC Yukon transmission. However, repeated engagement of the clutch disc can create heat, warpage, and scoring. These problems tend to make replacement necessary sooner rather than later. In recent years, many Yukon models have featured a traditional solid disc, as well as a dual mass unit in which primary and secondary masses are sandwiched together with spring dampers to absorb vibration and quiet shifts. A solid unit can often be resurfaced, but most DMFs cannot be. Internal damper failure or ring gear damage generally means a new Flywheel will need to be installed in your GMC SUV.

Each OEM GMC Yukon Flywheel 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 remove and reinstall a flywheel in 4.3L V6 engine on GMC Yukon?
A:
Raise the vehicle and support it securely on jack stands, then remove the transmission. Mark the relationship between the driveplate and the crankshaft with a marker or similar device, then remove the bolts that secure the driveplate to the crankshaft. If the crankshaft turns, wedge a screwdriver in the ring gear teeth to jam the driveplate. Remove the driveplate from the crankshaft. Since the driveplate is fairly heavy, be sure to support it while removing the last bolt. Clean the driveplate to remove grease and oil. Inspect the surface for cracks, and check for cracked and broken ring gear teeth. Lay the driveplate on a flat surface to check for warpage. Clean and inspect the mating surfaces of the driveplate and the crankshaft. If the rear main oil seal is leaking, replace it before reinstalling the driveplate. Position the driveplate against the crankshaft. Be sure to align the marks made during removal. Note that some engines have an alignment dowel or staggered bolt holes to ensure correct installation. Before installing the bolts, apply thread locking compound to the threads and place the retaining ring (if equipped) in position on the driveplate. Wedge a screwdriver through the ring gear teeth to keep the driveplate from turning as you tighten the bolts to the torque specifications. If the transmission front pump seal/o-ring is leaking, now would be a very good time to replace it. The remainder of installation is the reverse of removal.
