This video ONLY covers some of Kent's "tips and tricks" on installing a harmonic balancer back onto the front of the crankshaft on an old Mercedes engine. The specific procedure was filmed while doing a front crank seal replacement on a 1983 240D. These instructions will apply directly to all diesel engines from 1968 to 1985. The principles will also apply to many gasoline engines from the '60s, '70s, and '80s although those engines are not actually covered in this video.

Filming this 9-minute video was prompted by the number of emails we have received requesting help on how to reinstall the harmonic balancer when it was not marked or the engine was not set to top dead center before it was removed. Kent will show you how to rotate the engine to the correct position so you know you are installing the balancer correctly. He will demonstrate his "trick" on how he lines up the harmonic balancer with the two pin grooves on the end of the crankshaft (it is very hard to see). You will be amazed at this simple method to increase visibility so you can actually see what you are doing. He also covers properly preparing the bolt and 3 washers before installing them on the crankshaft.
This video does NOT cover removing the harmonic balancer nor tightening and torquing the big bolt. Those procedures are covered in his front cranks seal replacement manual and companion video ( available separately below )
