Question 1

What precautions should be taken when removing the harmonic balancer to avoid severe engine damage on Volkswagen Jetta?

Accepted Answer

In all models there is a possibility of severe damage to the engines, or even a variation in the valve timing with the removal of the crankshaft pulley when the crankshaft is not in the TDC position. Start with loosening the right-front wheel bolts, raising the front of the car, and placing it on jackstands and holding it firm with wheel blocks at the other end before taking the right-front wheel off. Then take off the splash shield, engine, engine cover and the right-front inner fender liner. Take away the drivebelts and turn the engine clockwise until the No. 1 cylinder has reached TDC. In case of 1.4L models, ensure that the crankshaft pulley does not turn with a special tool and loosen the crankshaft pulley bolt after which teeth on the pulley and crankshaft sprocket can be checked to be worn out. Install the new pulley with the retaining bolt by attaching it lightly with oil and ensuring that it is tightened to the set amount and finish the installation process in the reverse order. In the case of 2.0L, keep the crankshaft in place using a wrench on the center bolt, unscrew the pulley bolts, remove the pulley off the crankshaft sprocket and make sure to get a replacement center bolt in case it was removed. Install the new crankshaft drive sprocket bolt to the required torque and angle of rotation, locate the crankshaft pulley on the crankshaft drive sprocker, align the mounting holes and fit the pulley retaining fasteners and tighten them to the required torque. In the case of timing chain engines, disconnect the electric connector to the windshield washer reservoir and the screws to dismount the reservoir. To remove the hose in particular models, disassemble the air charge pipe that has fasteners and loosen the hose clamps. Rotate the engine clockwise and make sure that the No. 1 cylinder is at TDC and then ensure that the crankshaft pulley does not rotate and loosen the crankshaft pulley bolt. Take out two bolts in the lower timing chain cover, insert a special tool on the crankshaft pulley, and timing cover, and mounting bolts through the tool, into the holes in the crankshaft pulley. Take off all the crankshaft pulley bolt, verify the outer sleeve of the special tool, and insert the tensioning pin in the crankshaft. After securing clamp the knurled knobs of the special tool with a screwdriver and remove the tool as an assembly with the crankshaft pulley attached. Install the crankshaft pulley with the tensioning pin in place and make sure that it fits with the tooth contours and slide one of the special tools on the tensioning pin to check alignment. Loosely screw a lock nut and tighten it checking the seating of the vibration damper and then fit the special tool on the crankshaft pulley and timing cover. Take the tension pin out, insert a new pulley retaining bolt with O-ring hand tight, and when the crankshaft pulley bolt is tight, take off the special tool. Lastly, do not allow the crankshaft pulley to rotate and screw in the crankshaft bolt to the recommended torque and fit the new lower timing chain cover bolts and reverse the procedure.

Question 2

How to remove and install the harmonic balancer and related components on Volkswagen Rabbit?

Accepted Answer

Unscrew the bolts of the right front wheel, lift the front of the car and ensure it is kept on jackstands. Close the opposite end of the wheels and take off the right front wheel. Laying under the vehicle, take out the lower splash shield beneath the engine. Removing the engine cover This is done from above in the engine compartment. Take off the right front interior fender liner and the drivebelts. Turn the engine in the way it is normally rotated (clockwise) until the No. 1 cylinder is at TDC. To remove the crankshaft pulley, position the crankshaft without moving it out of the TDC position to hold it with a wrench on the center bolt and unscrew the pulley bolts and remove the pulley off the crankshaft sprocket. In case the center bolt was taken out, make sure to wrench the new crankshaft drive sprocket bolt to the required torque and rotation angle. Install crankshaft pulley on the crankshaft drive sprocket and align the mounting holes and set the pulley retaining fasteners and tighten them to the recommended torque. The rest of the installation process is the opposite of uninstalling. In the case of timing chain engines, disconnect the air charge pipe, with the clamps at each end and the air charge pipe. Unscrew both the hose clamps on the lower air charge hose and loosen the hose. Turn the engine in the way it is normally rotated (clockwise) until the No. 1 cylinder is at TDC. Install VW special tool #T10355 (or equivalent) to prevent the crankshaft pulley movement and remove the crankshaft pulley bolt, without ensuring the crankshaft is not moved out of the TDC position. Install crankshaft pulley to crankshaft and be sure that both flats of the tooth contours are in line with the tooth contours on end of crankshaft. Install a new O-ring and pulley retaining bolt attaching the bolt with the correct amount of torque. The rest of the installation process is the opposite of uninstalling.
