Spat Power Steering Belt With New Ross Tuffbond

[GTR_JOEY]

Well - don't get me wrong. I am very very happy to be told its nothing to do with it and find another reason for it.

As I said above, Ross is a good bloke to deal with, its good to buy Aussie, RIPS uses them too - and I still do have mine - so I am all for it NOT being anything to do with the balancer.

But when Piggaz started throwing belts and so did I, especially when I wasn't before hand - it raised alarm bells. Now ABR33.

So I felt it was worth mentioning - just in case. Lets hope we can find the real reason though.

Yea for sure mate,defintaly worth the mention, and i can imagine its rather annoying that the blet keeps getting thrown. Hopefully you can sort the problem soon and report back with exactly why its happening (ross balancer or not)

How much power are you making by the way?

in the mean time you should get one of those idlers for the belt, not too expensive i imagine and fairly easy to fit.

about ur timing belt slipping... that is very strange

[Piggaz]

He has one Joey.

[abr33]

But can anyone explain why i was doing flat out runs down an airstrip for 30 mins, and drifting around each turning end, and after doing the same thing after doing it 20 times already it comes off? done nothing different.

One thing I can say is the belt is quite old and shitty, could it be poor strength belts allowing stretch?

Has anyone thrown a gates racing belt? seem to be tougher..

yeah got the idler kit Joey - it did help - how could it not - but we noticed the belt still tried to walk up the back of the damper. Plus I want to know why my ATI ran without an idler and never had the issue. Remember this was the ONLY change. And hence why I was suss about it. As Ross pointed out though, RB26 Power Steering pumps often seem to be a little on the piss, hence we went to some effort to replace the bracket - face it and line it all up with a laser. Fat lot of good that did me though.. I am almost wondering if something has happened to the crank nose during changing them or something - makes no sense.

My car is only a baby in RB30 terms mate. 20psi - 350rwkw. Spins too 7200rpm - soft limiter courtesy Motec. Plus I drive like a pussy according to Gav. So I'm not bouncing off a 9krpm limiter or anything.

Frustrating doing power steering belts and then burning the crap out of yourself changing them between runs at an event. And one of them coming off decided to tear into my Spal Thermo wiring... grrrr...

What issues do people have with stock gtr ballancers that makes them change to ross?

Nissan would have spent alot of time/money designing these to work reliably on their engines, gtr stock rev limit is over 8000rpm.

Ive never had or seen a power steer belt spit off using stock ballancer.

Elite - what tension do you tighten the bolt to?

They get worn out over time and I imagine Nissan charge a mint to buy another one.. Other wise yea they are probably the best one you can buy

Interesting my mate just put a ross on as well and has spat his ps belt a half a dozen times as well ? making 350 kw ??

[BLITZ-26]

Isnt a rb26 500 or 600 nm ??

[sky30]

A rb30 in vl spec is 150nm im pretty sure.

[kitto]

RB26 is 446Nm

RB20, 25, 30 are 152Nm from memory.

I have no idea why thr RB26 is torqued so much higher.

Can confirm, drives like a pussy

Don't think its the same issue ( but I'll put it out there ), I've spat a couple of P/S belts with an ATI balancer, but only at 8500rpm and over 200kph, think there is enough flex in the clutch fan to just clip the belt..

Not the same issue as you Matt, obviously as you have electric/thermos, from memory.. but could be worth looking at for others.

[BLITZ-26]

the factory fan flexes that much....?? so your was mainly due to the RPM ?

[abr33]

So why is there the issue on my 25? or has it happened on others?

This is interesting, my fan tips have tiny tiny rub marks on them. I was going well in excess of 200km/h too. Not sure if that done it though I think it came off when i was in second though...

[tricstar]

can't be sure on either case.. there was black marks on the fan but don't know if that was the cause or the result of the belt shredding? but the fan does have quite a bit of flex ?

and both times its happened to me was at the track or an event at over 8000rpm in 4th, so 220kph+ ..?

when its not spinning, the fan tips are only about 10mm from the P/S belt.. ?? but I've only done 2 belts in about 4 years so I don't know that this is related to the Ross balancer issue ( if there is one )

[The Dan]

Torque figures above look right but I'd have to check my book. GTR would be tighter due to the metric superfine thread it uses (18x1.5) and the fact it's an 18mm bolt instead of a 16mm bolt in the 'lesser' models.

Remember boys and girls, it's all about correct tension, not lots of tension.

That 18mm bolt is definitely doing to need that much torque to apply the correct stretch to give it the exact preload it needs to never come off.

I've seen too many come loose recently....but come to think of it....all GTRs

Answering a question above about why replace the stock balancer - It's simple. Because they are shit

When they were brand new they were awesome. 20 years later.....shit

If you could pick only 3 things to modify in the engine of a GTR to make it near bulletproof at 600-800hp it's : 1. Rod bolts 2. Billet oil pump gear 3. Good aftermarket harmonic balancer

We have proven it many many times. Although given the choice, everyone knows my decision on stock rods

[R32 TT]

So the question on everyones lips (or mine) is what exactly makes them shit?

I can understand that newer designs/materials etc could make a better one - hence why I bought an ATI in the first place, but I am interested in why you say that - how does one 'measure' how well one damper is compared to another without some pretty special equipment?

ie something in your experience must have lead you to this?

...you know.... that hurts a little. I brought it on myself, but still.. where's the love.

my mechanic just got me a new r34 balancer through nissan for just over 400 buks... Cheaper then aftermarket
