Gates Belts Noisey ?

[BASHO]

I'm getting the timing belt service thingo done on my R34GTT next Tues, I'm having the timing belt, tensioner spring ,tensioner bearings and water pump replaced along with a wanky see through top timing belt cover fitted.

I'm planning on a Gates Racing timing belt being fitted.

The issue is that I've come across a number of posts where the Gates belt has apparently been noisey as, although many of the topics posts then divert into pulley belts for the aircon , power steer belts etc with no real conclusion at the end of the day.

The simple questions are--are Gates Racing timing belts noisey and if so why ?

The engine in this car is as quiet as a mouse and I'm not building a noise nuisance into it if I can avoid it.

SO THERE !!

Any comments or personal experiances to share anyone ?

No,

It it's noisy it's wrong... Most of the time people to them to tight...

Done right it will be fine..

My mate has a Gates Racing put on his 33 GTST and it was noisy.

no 1 Over tightening

no 2 In the past the only time a new belt seems to be noisy is if the bearings (tensioner and idler are not replaced). Thus being that new belt applies slight different load on the bearings. They are 90% of the time the source of the noise, if the belt was not over tightened

Hope this was clear

Thanks for that, good as gold, Gavin Woods/Autotec are doing the job so everything should be aces, I was only concerned that it may have been an integral characteristic if the Gates Racing belt.

Nope, I run gates belts and they are easily the quietest belts i've used.

You want noisy buy a gilmer belt lol

[gtr fan]

If you want to buy one I have a brand new in packet belt, which I purchased for my R32 GTR (I assume it fits all RB engines). I ended up going with a standard nissan item.

$90 including postage anywhere in Asutralia.

PM or SMS me on 0411 415 644.

[NYTSKY]

Not noisy. If its noisy you have done it wrong.

[BASHO]

Thanks mate already got all the stuff

The belt it's self will not be noisy, the big issue is doing it to tight. With the gates t/belt if it is to tight the coloured coating on the outside tends to rub off on the pulleys which then causes the noise which people just think is due to the belt it's self

[BASHO]

Well , I can now speak with the voice of experiance, the timing belt service (Gates Racing belt, tensioner bearings, spring and waterpump) was done the day before yesterday by Gavin Woods workshop Autotech and this belt don't squeel, whir, or otherwise make any noise in fact the engine noise is, if anything, quieter.

Pays to have it done as the belt that came out of my 98R34GTT 81000ks which I would have thought would have been changed at least once in the cars life looked like it was the original, didn't appear to be cracking anywhere or overly stressed or worn-just origional..

Go Figure

[mad082]

doesn't suprise me that it hadn't been done with only 81,000kms on the car. the service schedule says to do it at 100,000kms so that's what they do it at even though with low km driving there should also be a time frame thrown in for good measure, people just usually leave it until it gets to the set kms to change it

The time frame is normally 5year/100,000km. my R34 had only done 45,000 when i changed it. the car was 10years old at that point and the back side of the belt was starting to crack.

Well I obviously spoke too soon 3 days and 254 ks farkin noisey , was there when I pulled in to the garage this afternoon-horrible frakin thrummin throbbin whir, cant hear it when I'm on the move ---yet---but I let it cool down a bit then started it up wasn't noticable , took it for a run to bring it back up to operating temp pulled into the shed and there it was back again--worse than before aaaaaaaaaaaaaaaaaaaaaaaaarrrrrrrrrrrrgggggggggggggghhhhhhhhhhhhhhhhhhhhh !!!!!

SPEWIN !

Update--

it's quiet when cold and sounds a bit more like a syncopated srcaping than whiring alnost as though its catching on something when it's hot, can only just hear it inside when at idle and not atall when driving.

Any ideas anyone ?

[Duncan]

straight back to the workshop! in fact depending on how bad it sounds you might want to talk to them first and ask if they want to pay for a tow.

mostlikely just a bolt not tight under the cover but you don't want to take a chance considering it could wreck the whole motor.

OK been back to the workshop -twice - the problem is that this frakin noise shows up when the car is properly hot, that is a 30c+day and about a couple of hours worth of running around. it dosent help when I take it in to the workshop and I get a good traffic light friendly run as it cools enough to just be a gwruuur --gwruuur--gwruuur-slightly gratey pulsing noise . --writing on the inside if the belt has been blamed for this.

When it's cold it doesn't do it attall.

It didn't do it attall for the first 250ks and it worrys me that something is being progressively fraked up as when it does come on now it's progressively worse sounding.

When its doing it the noise is like a pulsing stuffed needle bearing crossed with a fan belt thats catchin the radiator shroud all inside an oil drum.

Any ides anyone ?

[BASHO]

Update--took it back to the workshop again and they re tensioned the belt again , it's now done another 300ks since and is as quiet as mice.

It was mentioned that it was not tensioned as much as an OE one would be this time around so I guess we can sumise that there is a fractional give in the OE belt to allow for engine expansion when hot and as Gates states "Zero give in a Gates Racing blue belt" which causing bearing noise if overtensioned when the engine is hot.

Or Like That

i just got mine done and mine is doing this noise... the place is trying to make me pay to get the belt re-tensioned.. did you pay or not?? jus wondering if i should give in and pay for it or not?

cheers mate

[simpletool]

Mine just got done it's loud as at idle. Can be heard easily in the cabin even in traffic - only below 900rpm does it make the noise. Above that it's quiet. Done at a workshop that deals with a lot of RBs. Considering just getting a Nissan belt put on instead even though I'll then have wasted my money on this belt.

It's way too loud to drive at night when quiet - definately I do not recommend Gates racing belt. Should have gone genuine but didn't know about this issue until after I bought it.
