Question 1

How to replace the harmonic balancer on GMC Acadia?

Accepted Answer

Replace the crankshaft balancer by starting with the removal of the engine mount strut bracket followed by the Drive Belt and Starter. The en 46106 (Flywheel Holding Tool) must be installed through the Starter hole while right frame side support comes from jackstands. The right side frame reinforcement bolts must be taken out while right side frame bolts are loosened to drop the right side frame approximately 2 inches. First use the j 38416-2 (Crankshaft Button) to insert into the crankshaft nose then apply the j 41816 (Crankshaft Balancer Remover) for removing the crankshaft balancer from the crankshaft. Installation of en 46106 to flywheel occurs as a part of the process. Use the j 41998-b (Crankshaft Balancer Installer) while inserting a nut and bearing and washer to install the crankshaft balancer by neglecting lubricant application on the front oil seal and balancer sealing surfaces of the crankshaft. Place the balancer on the crankshaft while lubricating its hub bore with the j 41998-b tool installed before the tool reaches 10 threads in the crankshaft. ((J 41998-B)) nut should be tightened until the large washer rests against the crankshaft end before (.J 41998-B') removal allows for (J 45059) installation of the crankshaft balancer bolt which needs to be threaded to 100 nm (74 lb ft) and further tightened for 150 degrees. The final step involves Starter reinstallation followed by use of an engine support fixture to raise the engine. Additionally, the engineer must install the engine mount strut bracket together with the Drive Belt.

Question 2

How to replace the harmonic balancer on GMC Sierra 1500?

Accepted Answer

Start the crankshaft balancer replacement by taking off the Drive Belt together with the cooling fan. When using a crankshaft balancer removal tool install a bolt shorter than the crankshaft balancer bolt which has matching threads inside the crankshaft before proceeding. Start by removing the crankshaft balancer bolt with its washer then proceed to take off both crankshaft pulley bolts and pulley. Use the crankshaft balancer remover and installer (J 23523-F) to take off and position again the crankshaft balancer. Apply j 23523-f plate and its bolts to the crankshaft balancer and secure the bolts at 25 n.m (18 lb ft) torque before inserting j 23523-f forcing screw into the plate to rotate the balancer off with clockwise torque. Take note of the balancer weights' position and length before cleaning and inspection of the balancer when needed. To reuse the front cover seal, apply a minimal amount of grease on the sealing surface before installing while keeping the balancer weight(s) in their correct positions. Put adhesive into the keyway of the crankshaft balancer before aligning it with the key to mount it on the crankshaft. Press the balancer onto the crankshaft by using the j 23523-f while you install the j 23523-f plate and its bolts with a torque setting of 25 n.m (18 lb ft). The threaded assembly of j 23523-f forcing screw, bearing, washer, and nut needs clockwise rotation until the balancer hub contacts the crankshaft position sensor reluctor ring. Put in the crankshaft pulley followed by its bolts and complete their installation by stowing them with 58 n.m (43 lb ft) torque values. Direction the crown of the crankshaft balancer washer so it points away from the engine before installing the washer on top of the bolt then torquing it to 95 n.m (70 lb ft). Reposition the cooling fan and Drive Belt in its proper place.

Question 3

How to replace the front harmonic balancer on GMC Yukon?

Accepted Answer

The toolset needed for crankshaft balancer replacement comprises crankshaft balancer remover (J 41816), crankshaft end protector (J 41816-2), flywheel holding tool (J 42386-A), crankshaft balancer and sprocket installer (J 41665) and angle meter (J 45059). The replacement process starts with belt removal from the air conditioning system unless vehicle has no air conditioning system. The beginner stage of replacement starts by taking off the lower Fan Shroud and then the Starter motor from the work area. Use the Flywheel holding tool (J 42386-A) to fit its teeth with the engine Flywheel teeth properly. No pre-marking is necessary for the crankshaft balancer before it gets removed. Use the Flywheel holding tool (J 42386-A) by mounting one m10-1.5 x 120 mm bolt and one m10-1.5 x 45 mm bolt while tightening them to 50 nm (37 ft. Lbs.). The crankshaft balancer bolt will maintain its use during the installation process. The crankshaft balancer remover (J 41816) along with the crankshaft end protector (J 41816-2) should be used to remove the balancer while cleaning and inspecting it when possible. Reposition the balancer directly around the crankshaft after which you should use the crankshaft balancer and sprocket installer (J 41665) for installation. Begin by spacing out the installation tool and apply a wrench to the hexoured threaded rod until the balancer starts moving with clock-wise nut rotation. Twist the installation tool in reverse motion and proceed with tightening the balancer until it has reached its complete position. The crankshaft balancer bolt from previous installation should be fitted followed by torquing to 330 nm (240 ft. Lbs.) then removing the bolt. Investigate the distance between crankshaft nose and balancer bore to measure between 2.4 - 4.48 mm (0.094 - 0.176 inch) recess. Recheck the installation following procedure measurements; carry out additional installation when needed. Use the angle meter (J 45059) to secure the new crankshaft balancer bolt at 140 degrees but start by tightening it to 50 nm (37 ft. Lbs.). To finish the repair replace the Starter motor followed by the lower Fan Shroud then install the accessory Drive Belt (if A/C is not present) and a/c Drive Belt (if A/C is part of the system) before performing the crankshaft position system variation learn procedure.
