GM 12561680
Flywheel

You must start by taking off the automatic transmission while marking down the engine Flywheel position together with its direction after removing it. Begin by removing the bolts from the Flywheel and taking out the Flywheel piece afterward. Two m11x1.5 mm bolts must go through the threaded spacer holes before you turn them clockwise for spacer removal from the Crankshaft rear side. Before installation apply the spacer to the Crankshaft end and follow by attaching the Flywheel and its bolts to the Crankshaft using extended Flywheel bolts when a spacer exists behind the Crankshaft. N3m threadlocker gm p/n 12345382 (Canadian P/N 10953489) and equivalent products need application on Flywheel bolt threads. The Flywheel bolt tightening process should begin at 20 nm (15 ft. Lbs.) before proceeding to 50 nm (37 ft. Lbs.) and finally reaching 100 nm (74 ft. Lbs.). Reinsert the automatic transmission after performing the tightening operation.

Initial steps to replace the engine Flywheel include removing the automatic transmission where you must record both the orientation and direction of the Flywheel before extraction. Following bolt removal from the Flywheel you can take out the Flywheel piece. Two m11x1.5 mm bolts should be installed into the threaded holes of the spacer which can then be removed from the Crankshaft rear by turning them clockwise. The installation requires placing the spacer onto the Crankshaft rear before adding the Flywheel along with bolts to install on the Crankshaft. Longer Flywheel bolts need to be used when installing a Flywheel spacer. You need to treat the Flywheel bolt threads with gm threadlock gm p/n 12345382 (Canadian P/N 10953489) or its equivalent product. Begin bolt tightening on the Flywheel by maintaining sequence following 20 nm (15 ft. Lbs.), continuing with 50 nm (37 ft. Lbs.) then finish at 100 nm (74 ft. Lbs.). You should reinstall the automatic transmission after performing these tasks.

Before servicing the flex plate start with the transmission removal followed by engine Flywheel bolt removal then remove the engine Flywheel. The installation procedure involves placing the engine Flywheel first followed by use of engine Flywheel bolts and completion with transmission reinstallation.

Start engine Flywheel replacement by removing the automatic transmission with note of engine Flywheel position and direction before the removal process. After removing the automatic transmission start by removing the Flywheel bolts before taking off the Flywheel. Two m11x1.5 mm bolts must be placed into spacer threaded holes at the Crankshaft rear before rotating them clockwise to detach the spacer. Before installation put the spacer on the Crankshaft rear face followed by attaching the Flywheel and its bolts while using longer Flywheel bolts when using a spacer in the Crankshaft. Add threadlock gm p/n 12345382 (Canadian P/N 10953489) or its equivalent material to the Flywheel bolt threads. Tighten the Flywheel bolts starting from 20 nm to 50 nm and ending at 100 nm while following the installation sequence. The automatic transmission installation process must be performed after finishing these steps.

The first step for engine Flywheel replacement requires automatic transmission removal followed by careful note taking of engine Flywheel orientation before the operation. The next step involves taking off the Flywheel bolts following removal of the Flywheel. The spacer removal from the Crankshaft rear requires clockwise rotation of two m11x1.5 mm bolts installed into the threaded holes of the spacer. Start by placing the spacer at the Crankshaft rear when needed before applying the Flywheel and its bolts to the Crankshaft. Also use extended Flywheel bolts with spacer installation. Slight threadlocking liquid such as gm p/n 12345382 (Canadian P/N 10953489) or its equivalent must be applied to all Flywheel bolt threads. Proceed with bolt installation onto the Flywheel by starting with 20 nm (15 ft. Lbs.) torque followed by 50 nm (37 ft. Lbs.) and finishing at 100 nm (74 ft. Lbs.). Reinstallation of the automatic transmission should be the next step after finishing this procedure.

Spilling the automatic transmission requires you to begin by removing the transmission while tracking Flywheel engine direction before taking it out. The first step requires removal of the Flywheel bolts followed by the complete removal of the Flywheel. First apply two m11x1.5 mm bolts into the spacer threaded holes and then turn them clockwise to remove the spacer from the Crankshaft rear. Installation procedure requires the spacer to be placed on the Crankshaft back and mechanics should use longer Flywheel bolts when working with applications featuring a Flywheel spacer. The water-proof threadlock should be applied to the Flywheel bolt threads before installation on the Crankshaft where each bolt must be tightened following a specific process beginning by securing bolts (1-6) in order to reach 20 n.m torque (15 lb ft) then progressing to 50 n.m (37 lb ft) and concluding at 100 n.m torque (74 lb ft). Installation should begin after you finish these procedures with the automatic transmission.

The first step in engine Flywheel replacement involves automatic transmission removal together with recording the orientation and direction of the Flywheel until complete removal. You must disconnect all engine Flywheel bolts together with any automatic transmission engine Flywheel that exists. Remove the clutch by paying attention to how the engine Flywheel is oriented while removing both engine Flywheel bolts and the manual transmission engine Flywheel when they are present. Add two m11x1.5 mm bolts to the threaded holes of the spacer if available and turn them clockwise to eliminate the spacer from the Crankshaft rear position. Install the spacer to the Crankshaft rear before adding manual transmission engine flywheels when needed followed by automatic transmission engine flywheels, while using longer bolts for flywheels that employ a spacer system. The Flywheel bolt threads must receive gm p/n 12345382 threadlock equivalent solution before installing the engine Flywheel bolts. The engine Flywheel bolt installation requires a sequence of tightening torque starting at 20 nm (15 ft. Lbs.) for the first pass then moving to 50 nm (37 ft. Lbs.) for the second pass until it reaches 100 nm (74 ft. Lbs.) during the final step. Use the clutch before mounting the automatic transmission when manual transmission is part of the vehicle.

Begin the engine Flywheel replacement by stripping out the automatic transmission when present then extracting engine Flywheel bolts and the engine Flywheel itself. Manual transmission vehicles must begin by removing the clutch assembly and then proceed with removal of both engine Flywheel bolts and engine Flywheel. Before installing the engine Flywheel you must check it for cleanliness and examine it for correct orientation through the "engine side" stamp. The engine Flywheel installation happens according to transmission type with three bolt-tightening steps beginning at 40 nm (30 ft. Lbs.) and ending at 100 nm (74 ft. Lbs.). Reinstall the clutch assembly when working on manual transmissions while automatic transmissions need their transmission to be reinstalled.

The procedure for engine Flywheel replacement starts with uninstalling automatic transmission units and continuing with clutch removal in cases where present. The next step requires you to remove the Flywheel bolts which should be followed by taking out the Flywheel (1 or 2). Remember to track how the Flywheel weights are placed before removing the manual vehicle transmission since these weights guide future assembly. A proper examination should be conducted on the Flywheel followed by necessary cleaning steps. A new Flywheel installation requires specific attention to manual transmission Flywheel weights which should be noted down because weights of matching lengths need to be installed in corresponding original positions. The installed new Flywheel weights ought to touch the Flywheel surface at a level point or just slightly lower. The installation of the Flywheel (1 or 2) must be done by positioning its locator hole toward the Flywheel locator pin. Use the specified order to install Flywheel bolts while tightening them to 100 nm (74 ft. Lbs.). The installation process ends with the restoration of both clutch components when present and any installed automatic transmission systems in place.

Clean and inspect the flywheel as needed.

Next, take out the flywheel bolts and then remove the flywheel (1 or 2).

First, remove the automatic transmission, noting the position and direction of the engine flywheel before removal.

If applicable, install two M11 x 1.5 mm bolts into the threaded holes of the spacer and rotate them clockwise to remove the spacer from the rear of the crankshaft.

Next, remove the flywheel bolts and then the flywheel itself.
