What is the crank pulley called?
Definition. A crankshaft pulley, also called a harmonic balance wheel or crankshaft sheave, is a grooved, wheel-shaped device that connects directly to the vehicle’s crankshaft. The crankshaft essentially converts the linear, or straight, movement of pistons into a rotational motion.
What is a crankshaft damper pulley?
A damper pulley, commonly known as a crankshaft pulley, is a pulley mounted at the front end of the crankshaft. It drives the acces- sory belts, which in turn drive the alternator, air conditioning compressor, power steering pump, water pump etc. The simple pulley has a damping effect on crankshaft stresses.
Whats behind the harmonic balancer?
The rubber inside the pulley is what actually absorbs the vibrations and keeps them at a safe level. In essence, the device is designed to help prevent crankshaft failure. The mass counteracts the torsional crank motions and in concert with the energy dissipating element absorbs the harmonics vibrations.
What is a harmonic balancer pulley?
A harmonic balancer is a front end accessory drive component that is connected to the crankshaft of an engine. The purpose of the harmonic balancer is to reduce engine vibration and in many cases, serve as a pulley for drive belts.
What is the main function of a crankshaft vibration damper?
The damper is designed to absorb torsional and vertical vibrations from the crank, as a result of the engine combustion process.
What happens if a harmonic balancer breaks?
If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively. The shaking will become even more pronounced, and therefore dangerous to the engine at high speeds.
Is a harmonic balancer and crankshaft pulley the same thing?
Is a crankshaft pulley and harmonic balancer the same thing? – Quora. No! They are two different things. The harmonic balancer slides onto the front of the crankshaft which has a keyway on it to keep it from slipping and a bolt and wide washer holds it in place.
What kind of timing belt does Toyota harmonic use?
You aren’t going to break it! Comes with the right sized metric bolts for the harmonic balancer on my Toyota 4.7L V8. It made taking the pulley bolt out a BREEZE. Last time I did a timing belt on another Toyota V8, I used a 2 X 4 with three holes drilled in it, making my own pulley holding tool.
How does a Schley work on a Toyota harmonic?
When it came time to install the pulley, we bolted the Schley tool to the pulley with the two provided bolts, plugged a 24 inch 1/2 inch drive breaker bar into the tool and oriented the breaker bar up inside the engine compartment. My friend held the breaker bar up top, while I climbed underneath and torqued the crank nut to 181 foot pounds.
Where is the pulley hole on Schley harmonic?
Hole in center of tool – allows access to removal of crank shaft bolt. Low profile design – no need to remove radiator or other components to access and remove Harmonic Damper Pulley. In Stock. In Stock. There was a problem filtering reviews right now.
What makes a Toyota pulley an OEM pulley?
OEM pulleys are exact fit parts that never need to be modified. OEM pulleys are made to perform at factory standards, so they last as long as the original parts. OEM pulleys come with a manufacturer’s warranty. At Olathe Toyota Parts Center, we’re dedicated to helping you save money on OEM Toyota parts.
