People need to acquire the following tools to replace a crankshaft balancer: j45059 angle meter, j41816 crankshaft balancer remover and j41816-2 crankshaft end protector and j42386-a flywheel holding tool and j41665 crankshaft balancer and sprocket installer. Start by removing the air conditioning Drive Belt if your vehicle has it or else proceed with removing the accessory Drive Belt. The maintenance process begins by taking away both the lower Fan Shroud and the Starter motor component. The j42386-a should have its teeth engaged with engine flywheel teeth whereas no marking process is required on the crankshaft balancer before its removal. Fasten the j42386-a by installing one m10-1.5 x 120 mm and one m10-1.5 x 45 mm bolt and torque them to 50 nm (37 ft. Lbs.). The crankshaft balancer bolt needs to be removed and should be used again for the installation. The j41816 alongside its counterpart j41816-2 should be used for removing the crankshaft balancer before it goes through cleaning and inspection procedures. To install the balancer position it directly on the crankshaft before using the j41665 to achieve alignment. Pass the threaded rod combined with nut and washer through the installer so the smaller end locks within the balancer while applying torque until the crankshaft starts to roll into place. The installation tool should reverse direction and the tightening process should begin until the balancer achieves complete installation. Reinstall the used crankshaft balancer bolt while applying torque of 330 nm (240 ft. Lbs.) before tightening it. Continue with the crankshaft installation procedure using the j41665 when you properly achieve 2.4-4.48 mm (0.094-0.176 inch) recess of the crankshaft nose into the balancer bore. A new crankshaft balancer bolt needs installation following an initial torque to 50 nm (37 ft. Lbs.) followed by torque to 140 degrees using the j45059. The last step includes Starter motor installation along with lower Fan Shroud and accessory Drive Belt (unless A/C is present) followed by a/c Drive Belt installation before conducting the crankshaft position (CKP) system variation learn procedure.

The first step to replace the Crankshaft balancer involves removing either the air conditioning Drive Belt with its presence or the accessory Drive Belt without it present. The replacement process starts with lower Fan Shroud removal as well as Starter motor removal. The teeth from the j 42386-a must match perfectly with the engine Flywheel. Fasten the j 42386-a with one m10-1.5 x 120 mm and one m10-1.5 x 45 mm bolt. The bolts should be tightened to 50 n.m (37 lb ft). Keep the Crankshaft balancer bolt available for reinstallation because it will find use when the replacement process begins. The j 41816 together with the j 41816-2 will be utilized to extract the Crankshaft balancer so you can clean and perform inspections. Position the Crankshaft balancer straight on the Crankshaft using the j 41665 and j 41478 tools for assistance. The j 41478 tool needs assembly with its components which include a threaded rod, nut and washer for insertion into the balancer. Use a wrench to hold the threaded rod hex end while clockwise rotations of the nut will begin the balancer onto the Crankshaft. Proceed with tool reversal while putting the large end against the balancer and maintain nut rotation to complete Crankshaft balancer installation. Use the used balancer bolt to tighten it to 330 n.m (240 lb ft) before removing it to measure the Crankshaft nose position in the balancer bore which should be 2.4-4.48 mm (0.094-0.176 in) deep. Perform the installation process again with the j 41665 only when required. The new balancer bolt for the Crankshaft needs installation while you start tightening it to 50 n.m (37 lb ft) and continue with 140-degree turn using the j 45059 tool. The repair ends with performing the Crankshaft position system variation learn procedure and reinstalling the Starter motor together with the drive belts and lower Fan Shroud according to applicable steps.

Install the J 23523-F screw, bearing, washer, and nut, rotating the nut clockwise until the balancer hub is seated against the crankshaft position sensor reluctor ring.

Assemble the J 41478 with the threaded rod, nut, and washer, inserting the smaller end into the balancer and tightening until the balancer is started onto the crankshaft.

No, marking it before removal is unnecessary as it is balanced as an individual component.

Repeat the installation procedure with the J 41665 if necessary.

The lower fan shroud and the starter motor.

Utilize the Crankshaft Balancer Remover (J 41816) and the Crankshaft End Protector (J 41816-2).

Assemble the threaded rod, nut, washer, and installer, inserting the smaller end into the front of the balancer. Hold the hex end of the threaded rod with one wrench while rotating the installation tool nut clockwise with another wrench until the balancer is started onto the crankshaft.

J 45059 Angle Meter, J 41816 Crankshaft Balancer Remover, J 41816-2 Crankshaft End Protector, J 42386-A Flywheel Holding Tool, and J 41665 Crankshaft Balancer and Sprocket Installer.
