call a dealerships parts department, same Part Number? also, speak with the shop foreman and pick his brain for a while...and call a couple dealerships, as opinions are like A$^^%%HOlES, but three A*%&*%HOLES that are the same will probably be correct! :) LOL also, Everyone should have a manual for their vehicle, and the library should have a professional shop manual available, for FREE, in the reference section(make copies of the correct sections) read up and fix it like a PRO! :) good luck-Dave
The harmonic balancers function is to reduce vibration between the engine and the crankshaft. To replace the harmonic balancer requires a specific tool available at an auto parts store. Loosen the crank pulley via 4 bolts to access the balancer. Using the tool remove the harmonic balancer from the crankshaft.
I think they are one. Harmonic balancers usually are integrated as the main driving pulley in a serpentine system. Call a toyota parts department (dealer) to make sure.
The harmonic balancer torque specifications are different in each type of engine. The general torque specification is between 120 pounds and 180 pounds.
the harmonic balancer on the 350 is about 10 inches in diameter compared to a 305 it has about 8 inch diameter on the harmonic balancer
your balancer is bad. balancers are in two peices pressed together by a thin layer of rubber in between the two .
The harmonic balancer of an externally balanced engine will have some type of fairly substantial offset weight either cast into it, or sandwiched between the timing chain cover and the harmonic balancer.
The oil leak is probably comming from the top of the oil pan there is a rubber gasket that goes between the oil pan and the water pumb which would make it look like its comming from the harmonic balancer, try replacing the oil pan gasket this should fix the problem. New answer: There is a small round oil seal / Harmonic balancer seal that fits in the timing cover and the balancer slides through the center of it. That is probley were your oil leak is. Most of the time the balancer itself gets a groove wore in it over time from that rubber seal running on it. You can repair the balancer by buying a Harmonic balancer repair sleeve/ speedy seal. Also replace the front timing cover seal.
Look at your harmonic balancer the 1 on the 350 is bigger than the 1 on the 327.
Crankshaft sensor for the 96 olds 3.8 v/6 is behind the harmonic balancer mounted on a bracket. It is adjustable and must be set properly to avoid damage to the replacement. There is a clearance issue between the sensor and the blades attached to the back side of the harmonic balancer.

No they do not. If you look at it real close you will see that it has a piece of rubber between the 2 steel parts that make the balancer, the rubber has sliped / worn out. The balancer is made of 2 pieces of steel with rubber in between them. REPLACE BALANCER. Before you take it apart make sure that the pulley that is bolted to it is not on crooked are bent. May just need a pulley put on it.
between 150-180. anywhere in that area is fine
The balancer is made of two pieces of still that are pressed together with a solidpiece of rubber between them. The most common problem is the rubber startscoming apart. and the outside of balancer spins on the end side part,and wobbles.Replace balancer
The harmonic balancer and flexplate are externally balanced on the 400, meaning the balancer isn't smooth and consistent all the way around. The flexplate for the 400 has a balancing weight welded to it. The 350 is internally balanced and has the typical smooth balancer and unbalanced flexplate.
In most cases no, it is two pieces pressed together with rubbber in between. It is called the vibration damper or the harmonic balancer.
Slide the balancer on the crankshaft snout as far as you can by hand, then put a harmonic balancer installation tool in and crank it down until it bottoms out. If you can't afford to buy the tool, you can make one with a piece of 1/2-20 threaded rod, a nut, and some big thick washers. Put grease between the washers so they will slip easily while you're tightening the nut.
The easiest way is to look at the Harmonic Balancer. The 305 has a wider thicker balancer than the 350. Pus the timing tab on a 305 is located ON the timing cover and the 350 is bolted on the with the cover bolts. Riky9
If the problem was not there before the repair then I would be looking at the repair itself. Could the pistons be installed backwards? Was it the correct crankshaft without a doubt? Did you match the casting numbers? Balancers only give a problem if the rubber between the 2 pieces comes out.
The engine is equipped with two. Which one needs replacing? One is located between the engine and transmission on the rear of engine. And the other is located behind the harmonic balancer.
There are two places that a harmonic balancer can "come loose". # The center retaining bolt can come loose. That usually means someone didn't adequately tighten it. # The outer ring can come loose, which really means that the rubber between the center pulley and the outer ring has deteriorated. Find out which it is and if the balancer has separated, just replace it. If it's a loose bolt, put a drop or two locktite on the threads then retighten the bolt. But someone will hate you when they have to disassemble the engine.
Some people mistakenly change the harmonic balancer or the timing cover, without matching it up. Some had a timing mark located at the top center of the timing cover, and some were off to the side (between 1 and 2 o'clock) If you have a mismatched balancer & timing cover, you will not be able to line up the marks. Sometimes the rubber goes bad, and the outer ring of the balancer slips... which would cause the timing mark to move.
Torque Setting for VS Commodore Harmonic Balancer Bolt- between 270-320 NM. The Best way is to check the bolt torque setting before you remove it.
The assembly is called a "Harmonic Balancer" or "Harmonic Damper" in Europe. The Rubber acts as a damper to smoth the engine vibrations at certain speeds. The Rubber is not available seperately so most people won't know its called a "Damper"
