Harmonic Balancer

[StevenN]

13408-67020 is the part number. Look here - http://www.google.com.au/url?sa=t&so...ZXPAWkLHc08MUA - at page 26 and the prado with the 1KZ-TE Engine and the HB1132-N which is the Harmonic Balancer for this engine.

Hi Nev & thanks for the info, but

I have followed the link and I am not saying it's wrong but it has the prado as being
90 SERIES 3L 3/00-ON 1KZ-FE (4) 13408-67020 HB1132-N EP091 (IG)

mine was built 1994.

why so many when they all look the same on top?

[NiftyNev]

It's the correct one. I just linked to that because I don't have an aftermarket link that lists the Surf and this covers Aussie models with the same engine. The Prado should be listed as a 1KZ-TE not -FE. I believe this is a mistake. You often find errors in listings like this. The genuine number and the aftermarket part number are correct. Why won't anyone believe me?

This link will show a pic and dimensions.

Jesus, did you see the price for the pulley on that Aussie parts list?

No! Where did you get the price from? I don't see any prices.

Hi Nev

I don’t think it’s a case of not believing you. In my case its just I am hoping it’s not so bad or being sure that the pulley off a 2.4ltr will fit.
I think the main reason for doubt is that it looks like most of the posts where people have had problems are from 2.4ltr owners not 3.0ltr.
Also the usual suppliers in the UK do not list the pulley for the 3.0ltr

I will still have to look at removing the old one before take the plunge and buy the new one.
I am toying with the idea of refurbishing the old one with industrial super glue as others have done.

Will just have to see how it goes

But thanks again for your help

Regards

Steve

http://www.toyodiy.com/parts/q.html has some prices, whether they are uptodate, who knows?

Your part number is correct

The rubber is inside it by the way Steven.

I believe you Nev!

As said though, never heard of it being a problem on the 3 litre and others have stated it doesn't exist (the rubber bit, not the pulley). I was just trying to set the record straight through a bit of rigorous investigation.

I see someone speaking about harmonic balancers, wich there are two on the 1KZ-T(E) engine and people talking about the damper wich is a different thing...

The harmonic balancers are the two shafts inside the engine block that are moved with the gears behind the timing belt cover (The 1KZ-T has a part of the distribution made of gears). The damper is the big pulley attached to the crankshaft that has a rubber pad to damp, as its name indicates...

I'm in the process of rebuilding a whole 1kZ-T, yesterday we undid the harmonic balancers hehe

2.4 won't fit.

Wouldn't that defeat the purpose. You will be turning it into a solid pulley which would no longer have a dampening effect and your crankshaft will be destroyed.

A harmonic balancer (also called crank pulley damper, crankshaft damper, torsional damper, or vibration damper) is a device connected to the crankshaft of an engine to reduce torsional vibration.

Every time the cylinders fire, torque is imparted to the crankshaft. The crankshaft deflects under this torque, which sets up vibrations when the torque is released. At certain engine speeds the torques imparted by the cylinders are in synch with the vibrations in the crankshaft, which results in a phenomenon called resonance. This resonance causes stress beyond what the crankshaft can withstand, resulting in crankshaft failure.

To prevent this vibration, a harmonic balancer is attached to the front part of the crankshaft. The damper is composed of two elements: a mass and an energy dissipating element. The mass resists the acceleration of the vibration and the energy dissipating (rubber/clutch/fluid) element absorbs the vibrations.

Over time, the energy dissipating (rubber/clutch/fluid) element can deteriorate from age, heat, cold, or exposure to oil or chemicals. Unless rebuilt or replaced, this can cause the crankshaft to develop cracks, resulting in crankshaft failure.

H/B Crank Pully

Hi Nev

The refurb idea is to rebond the rubber not replace.

As you have stated the 2.4ltr won't fit so I will need to obtain the correct part which couple be difficult.

I will have to re-mail Roughtrax again to see if the can supply.

Other than that I will be looking for a second hand one.

Saw something on fleabay that ammused though.
Someone is selling a Aircon tensioner pully as being in excellent condition.
The thing is nearly 15 years old.
I wonder if he gives a lifetime guarantee?

Those are balancing shafts.

Are you sure that's actualyl what it is?

[NiftyNev]

I'm still waiting for someone to actually confirm the 1KZ-TE has a "Crankshaft Pulley" that is a Dampener, although I am 99.99% sure they do. Where's Tony? Surely he has done one at sometime. I have done the 2.4 but not the 3 Ltr.

Tony is either on the roof or in the pub

Looking at this : http://www.tradekey.com/product_view/id/166449.htm

It would appear that this part is the same as on a Honda Civic and some kind of Mitsushiti I've never heard of. Looking around, it would appear that the Civic one, at least, is dampened.

Harmonic Balancer

Hi All

Just wondered if any body had more to offer in the way of solving me problem.

If it is the crank pulley that needs replacing then I need to get one.

All the usual Surf parts Supplers list pulleys for 2.4ltr but not 3.0ltr

Anybody know where to go?

Many thanks

Steve
