:D 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 !! :P

Any comments or personal experiances to share anyone ?

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 :P

:P 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.

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.

:ph34r: Thanks guys , in first thing tomorrow , fingers crossed , I'll post result , but I'm sure they'll be apples.

Thanks mate already got all the stuff :down:

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

;)

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 :)

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.

:D 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 ?

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 ?

  • 4 weeks later...

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 :)

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.

    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
    • Welcome mate. Any pics? Even with a DE I'd be well happy if I had that as a 1st car.
