What does a harmonic pulley damper do?

What does a harmonic pulley damper do?

The harmonic balancer (also called “crank pulley damper”), connected to the crankshaft of an engine, reduces engine vibration and serves as a pulley for the drive belts. The balancer or “damper” is composed of two elements: a mass and an energy-dissipating element.

Can a crankshaft be removed without pulling the engine?

Although crankshafts are traditionally removed after the engine has been pulled from the engine bay, it is possible to remove the crankshaft without pulling the engine. Step 1 Remove the engine’s belts.

What causes the oil seal on a crankshaft to wear out?

Tremendous force is generated through the crankshaft, and over time the bearings that allow the crankshaft to turn freely can wear out. In addition, at the back of the crankshaft lies an oil seal. If this oil seal becomes corroded, an oil leak will result.

What’s the best way to loosen a pulley bolt?

Grab a block of wood/cinder block or whatever and take socket wrench 1 and set it on the block while making sure that the socket is on one of the crank pulley bolts. Take the other socket wrench and use it to break loose the other 3 pulley bolts. Turn the crank/switch wrench positions until all 4 pulley bolts are loose.

Which is the most stubborn crankshaft pulley bolt?

Crankshaft pulley bolt is the most stubborn, highly torqued and perhaps the most challenging bolt to remove in a car.

Do you need a puller to remove a balancer?

I could be wrong. Starting in ’91 the 3800 balancer was a tapered fit to the crankshaft and required a puller to remove it. The 3800 in the ’88-’90 Reatta didn’t have a taper on the crankshaft and the balancer just slipped onto the crank. Normally no puller is needed. Look into the holes in the balancer in the photo below.
