Harmonic balancer

[laney]

Hi all has anyone had any experience with ross balancers I have read some on here but would like more up to date on how people have found them I have a Dayco power bond it is on it's way out have a great disliking for anything Dayco. So any help would be great thanks Phil

[V8Ian]

Supposed to be the RR (Rolls Royce or Range Rover? [bighmmm]) of balancers, no complaints about mine.

I have Ross performance balancer on both my discos and it’s been great no complaints

[d2dave]

I have a Ross on mine. Had it for about 5 years now.

[Epic_Dragon]

I've just ordered a Ross one, so joining the crew with one very soon!

did you order the special too as well to hold it ?

[Epic_Dragon]

I have my own tool I made years ago to hold it. Have just replaced timing gear on mine (also put timing pin in crank to hold motor)
The huge bolt that holds the harmonic balancer on is crazy torque (460nms) and you have to replace the bolt, can't reuse original

I have replaced about 15 Harmonic balancers for people so I know it’s a TTY bolt, I do have the tool also to put the correct depth for the timing case seal as well, many people don’t realise that the seal sits in a certain depth

The hub nut is 490nm which is decent but the 750nm W&B torque wrench makes light work of it

[Epic_Dragon]

Thats a lot! Doing it for first time. I don't have a big torque wrench and hadn't found one, couldn't afford to buy one that does it and tried kennards hire to hire one. They didn't hsve one but awesome fellas there contacted a bus and truck repair place who have one and are going to help me out when the harmonic balancer arrives. They are absolute legends [emoji122][emoji120]

That’s fantastic I’d replace the timing cover seal as well

[d2dave]

I was lucky when I got mine. They were out of stock when I ordered mine and the run of new ones took longer than expected.

As a good will gesture they threw in the holding tool free of charge.

[Epic_Dragon]

I did indeed replace it. Also painted the timing cover. That and rocker cover now match my purple wheelchair [emoji108]

They didn't have any stock with my order either, and said approx 2 weeks to manufacture. It was posted earlier this week but auspost being slow. Thought I'd have my car back this weekend but still waiting for the harmonic balancer to arrive

So an update the harmonic balancer has been replaced still had a rattle when you turned the A/C on disappeared when A/C turned off, so my mechanic went looking for some other reason for the noise after much searching found 2 of the 3 exhaust nuts that hold the exhaust pipe to the turbo were missing and the 3rd was very loose. I have now replaced the 2 missing bolts my mechanic tightened the loose nut so hoping all is good now.

[NBartels]

I've a question to those that chose the Ross Harmonic Balancer. What made you choose that brand?
Reason for my asking is that I'm trying to figure out the cause of the noise vibration and harshness (NVH) in my TD5 Auto that occurs mainly at 2250 RPM.
Of all the threads about this issue on all the forums, there is no definitive answer.

However, the is is an engine revolutions related vibration, not related to the gear the vehicle is in.
So in my view its in the engine or Torque Converter or some where in between.
Hence I'm toying with the idea of replacing the Harmonic Balancer to start with but want to be sure it will be a quality one.
Has anyone any views?

[V8Ian]

I used Ross on recommendation for performance and longevity. Been happy with it for over four years.

[Epic_Dragon]

I just put one in my car recently. Had to pull old harmonic balancer out as timing gear basically went boom. Discovered old hb was also pretty well past use by so did some research after fellas here recommended it. I upgraded to one based on the wonderful reviews here, and my want for a smoother motor so to speak. I find it very noticeable how smooth my car is now running. Some was likely stretched timing chain too but that hb has made a massive difference. Wanting a longer service life as well. I depend on my car more than most as it is the only car I can drive with my hand controls. So helping the old girl stay reliable :)

Just to clarify, you have eliminated the cause being hand brake shoes and backing plate, by lifting the hand brake up gently when it's vibrating?

[NBartels]

Yes, I've eliminated the Handbrake shoes. Gently lifting the handbrake while engine is at 2250 RPM makes no difference. The harshness is not from the handbrake area. Still believe its in the engine somewhere.

They run different mapping which can change vibration a little, bearing in mind 5 cyl engines are a little prone to it with harmonic resonance and the like.

I'd be checking the engine mounts.

[NBartels]

Yes, I've changed the engine mounts.
Unfortunately Rimmer Bros sent me the wrong ones. Aftermarket instead of Genuine.
There was no change to the Drone / NVH.

[NBartels]

I'm Not sure if its EU2 or EU3 . How do I check ?.
Its a 2004 model...
And I've heard some people talk about geing a different tune loaded into the computer, but haven't investigated this too much.
Maybe the air / fuel ratios affect the way the engine feels, much like pinging in a petrol motor if timing or distributor map not right.

[NBartels]

By the way Epic_Dragon , Thanks for thos pics on the Harmic Balancer, those are really good pics of the front of the TD5 with all the grill etc removed.

[NBartels]

Another question, and maybe this should go to the wider AULRO community, Has anyone with a TD5 that is experiencing this NVH at 2250 RPM gone down the road of doing a full rotating assembly balance.
I mean disassemble the whole engine, weighing conrods and pistons, grinding off excess metal to get each component within a gram. ?
Can also get the crankshaft rebalanced as well, although technically it should be already to some degree from the factory.

They doing this for race cars, but also for street cars to get a much smoother running engine.
I've not seen it mentioned on any forum.
Expensive exercise I know, but this drone is a Pain..

I just pulled the trigger on a ross one today.

I have felt the motor feels a bit rickety, and I put it down to bad engine mounts, but since my re-fresh and install of the new motor with new mounts I kept the pully and feel like this motor has the same vibes.

Today I just installed a brand-new OEM spec fan clutch, as I knew mine was sus and it changed the way the vibes feel, really smooth now when cold all the way up to the top of the rev's but after a warmup feels a bit rickety again. I have also noticed some chirping sounds on deacceleration / engine braking like a rattle and when turning off the engine a bit of a clunk, all most sounds like the exhaust is hitting the body, but its not. So, I pulled the trigger expecting it's going to let go any day.

I will report back once replaced.

It won't be anything to do with AFR though.

As I mentioned earlier, you have a 5 cyl engine, notorious for vibration.

I doubt having it all balanced will make much difference.

EU2 and EU3 run vastly different strategies regarding "engine smoothness".

I personally feel the EU3 might be the worse of the 2 for vibration.

If you have wonky engine mounts they can be a dog.

Auto or manual box?

Sorry to the OP this has gone a bit OT...

[NBartels]

Automatic

[NBartels]

It has the EGR removed.

[laney]

I went the Ross balancer as I was sick of the crap Dayco had when I spoke to someone at Ross they said that the balancer was tested to 1000 hp and 11000 rpm. They were modeled of the skyline balancer it is now fitted no complaints.

Isn't a chirping sound and a bit of a clunk possibly the double cardan joint on the way out.

I know it's off topic but thanks, I forgot about that link to the drive shaft, I inspected and was able to see a lot of movement in the u-joint tran side when moving it around in park. Might have saved my bacon there :D, thanks.

[laney]

The ross balancer is slightly smaller than the OE or Dayco balancer my mechanic found that the 7PK1800 serpentine belt was a touch to big the tensioner bounced around to much a 7PK1790 fits great this is for a non ace car but drop 10mm for ace car would be the same.

Pays to check, for sure. That thing lets go and it's new trans time.

I went to do mine today but my socket that fits the 3/4" torque wrench is a deep impact socket, no good with the engine in the car, and radiator. Until next weekend. I wonder if I will have this fan belt issue, my belt is new so might not have stretched much yet.

Yeah, the last time I looked when dropping in the new engine it looked good, maybe all the new torque killed it :D but chirping deffo is the sound of it going!

Yes those are scary when they let go [emoji15] I had just been driving at 100kmh a few kms before mine let go. Thankfully it let go at like, 5kmph. Just leaving traffic lights. In the centre of an intersection. Car would not move as the fallen drive shaft was wedged. I couldn't get out safely being in a wheelchair.
Raa were extremely fast, got the broken driveshaft out and I was then able to drive out of the intersection.
Truck home as did not want to drive the 50km home with only 1 driveshaft.
It marked thr transmission, and had not been barely moving, it would have been nasty when it broke.
I have photo somewhere of the state of the drive shaft. I'll try find it

[Four Loko]

Got the job done today, 42degrees in a non-insulated shed..[bawl] the torque wrench was all most too hot to use.

For me I feel this has smoothed out the higher rev range from 2,000+ to run out. It felt like the torque response was a bit different but maybe I am imagining, or it was just the heat. When it cools down, I give it a good flog.

Not much room with the big torque wrench, I also used the starter to undo it, no problems.
