Can I Swap Harmonic Balancer? - Fixanswer

Are harmonic balancers interchangeable?

All harmonic balancers ARE interchangable but you may need to get the right pulley for the power steering

. Some had a rubber mount (old style. around the hub and newer ones were all iron and smaller but they DO interchange without affecting balance.

Will a 305 harmonic balancer fit a 350?

It

will fit The 305

and the 350 have the same crank in them. However if your balancer is the original 1985 It is a good idea to change it due to the flex mount getting old and slipping.

Does the size of a harmonic balancer matter?

No matter what anybody tells you,

size does matter when it

comes to the harmonic balancer you use on an engine. Putting an incorrectly-sized balancer on an engine will do more than just cause it to not reach its full performance potential … it will cause serious damage to the rotating assembly.

How long do harmonic balancers last?

On certain engines, sometimes these last forever, last the life of the engine. And certain engines they might only last 50,000 miles or

less than 10 years

. This is a good example – because it’s got such a massive piece of rubber – you can see the rubber literally tears apart into two sections.

Do all engines have a harmonic balancer?

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.

Does the weight of a harmonic balancer matter?

No, it does not matter on the size

. However, one can shim the swaybar to provide clearance by adding the spacers under the bushing holders on the frame and order an 8′′ balancer. If you do order and install the smaller mass balancer, you will notice an improvement in engine acceleration – less mass to spin up.

How do I know what harmonic balancer I need?

Cracked, bulging or missing rubber.
Harmonic balancer wobbles.
Separatation between the hub and outer ring.
Timing marks slipped. Timing error code or mis-fire.
Excessive wear on main bearings.
Oil pump failure.
Broken crankshaft.
Loosening or broken bolts.

What size is a 350 harmonic balancer?

Nearly all 350s came with an

8-inch

balancer because of their relatively long stroke. An 8-inch balancer was used on the short-stroke, 3.0-inch-stroke, 302 Z/28 engines because those mills were intended for road racing.

Is it normal for a harmonic balancer to wobble?

When the rubber isolator begins to deteriorate, the balancer usually begins to separate, creating a noticeable wobble when the engine is running.

What causes a harmonic balancer to wobble?

Does a harmonic balancer need to be balanced?

Harmonic balancers are misnamed.

They do not balance an engine

, rather they absorb and remove unwanted vibration due to torsional twisting of the crankshaft. … Dampeners are like torsional shock absorbers used to dampen torsional twist and vibration in an engine.

Do I need a SFI harmonic balancer?

NHRA requires the use of an

SFI 18.1

harmonic damper for any car running faster than 10.99 in the quarter-mile. Beyond that requirement, any engine that has been modified for increased horsepower and/or higher rpm limit can benefit from the use of a quality harmonic damper.”
