How to remove and refit the harmonic balancer on the auxiliary drivebelt for 1.6 litre diesel engine on Volvo S40?

To remove the auxiliary drivebelt, first, lock the harmonic balancer by putting Volvo tool No 999 7169 in the hole in the right hand face of the engine block over the lower section of the flywheel, turn the harmonic balancer till the tool is locked with the corresponding hole in the flywheel. If the Volvo tool is not available, a 12mm rod or drill can be put inside the hole to prevent it from rotating. Next, with the help of an appropriate socket and extension bar, unscrew the retaining bolt, remove the washer and slide the harmonic balancer off the crankshaft. If the harmonic balancer is a tight fit, a suitable puller can be used, and it has to be made sure that the retaining bolt is refitted without the washer, to prevent damaging the crankshaft. For refitting, put the harmonic balancer back in place on the crankshaft, clean the threads of the retaining bolt, and put a coat of locking compound on it. Refit the retaining bolt and washer, tightening it to the specified torque and angle and preventing the crankshaft from turning. Finally, refit and tension the auxiliary drivebelt.

Volvo Harmonic Balancer

Volvo Harmonic Balancer is responsible for keeping the crankshaft steady by absorbing torsional vibration and keeps every engine running more smoothly and longer, a simple part of the engine that protects power components and ensures against costly damage. Volvo is known throughout the world for placing people first, from pioneering the three-point seat belt to equipping all vehicles with responsive brakes and easy-to-read instrumentation to foster confident control. Drivers of Volvo vehicles enjoy the way the simple, yet strong construction gives peace of mind. Today Volvo invests heavily in electric powertrains and plug-in hybrid testing, proving that safety and sustainability can go hand in hand without losing performance. Such is the forward thinking that owners trust mile after mile of a reputation for durability. The Harmonic Balancer complements this philosophy by introducing an invisible layer of protection in the engine bay. Built with a sturdy steel hub, an inertia ring, and a resilient rubber layer, the Harmonic Balancer mounts on the crankshaft, slightly lags each power pulse, cancelling twist, which can crack metal, loosen pulleys, or shake fasteners. Because component belts ride directly on its outer ring, a healthy Harmonic Balancer also maintains the smooth spinning of the alternator, water pump, and cooling fan that supports quiet operation across the entire Volvo lineup.

Q: How to remove and refit the harmonic balancer on the auxiliary drivebelt for 1.6 litre diesel engine on Volvo S40?
A:
To remove the auxiliary drivebelt, first, lock the harmonic balancer by putting Volvo tool No 999 7169 in the hole in the right hand face of the engine block over the lower section of the flywheel, turn the harmonic balancer till the tool is locked with the corresponding hole in the flywheel. If the Volvo tool is not available, a 12mm rod or drill can be put inside the hole to prevent it from rotating. Next, with the help of an appropriate socket and extension bar, unscrew the retaining bolt, remove the washer and slide the harmonic balancer off the crankshaft. If the harmonic balancer is a tight fit, a suitable puller can be used, and it has to be made sure that the retaining bolt is refitted without the washer, to prevent damaging the crankshaft. For refitting, put the harmonic balancer back in place on the crankshaft, clean the threads of the retaining bolt, and put a coat of locking compound on it. Refit the retaining bolt and washer, tightening it to the specified torque and angle and preventing the crankshaft from turning. Finally, refit and tension the auxiliary drivebelt.
