Gates Timing Belt R33

[Munkyb0y]

thats a load of shit. i had a gates (blue) belt put on. it was noisy, i took it back the the retard who fitted it and told him to re-tension it.

problem solved. never took my car to him again. belt has never made a sound since.

like I said, IN MOST CASES... not all.. read the post...

[Munkyb0y]

Fair enough. In my case it was caused by over tensioning.

[crofte]

Could this gates belt problem cause pre detonation (pinging) anyone?

Mine had the same humming just before we replaced with a gates one and new tensioner and idle pulley.

With the new bits on, no noise what so ever.

[sinistaGTR]

thats crap i put one on with my engine rebuild never hummed at all lol never had it retensioned either

[rb180]

so if the gates belt is correctly tensioned with new pulleys then it shouldnt hum ?

[Hootchy]

I put my gates belt on aswell as new Idler/tensioner bearings. It's never made a sound

Hmm reading through this.....mine whirs like a bitch......now im thinkng the tensioners might need replacing...any one know the part number and or rough price for the whole lot.....i have a gates belt but its the black one.

I would suspect the tensioner bearings for the noise first and belt (as in belt not fitting the gears neatly) second, more than likely the warn/loose old belt has reduced the tension on the tensioner bearings etc and now that you have put a new belt on it is highlighting a problem that was already there - due to the extra tension on the bearings. Another thing that may be contributing to the noise could be the extra strength the blue gates belt has/retains over the std belt, to me this would make sense that the belt must be less stretchy than the std and therefore this would also mean the bearings are being submitted to extra tension and cause any wear in them to be more easily noticed.

I have used Gates belts on a few engine rebuilds in the past and never had a problem with any of them. If replacing the bearings doesn't fix the noise and your gears are in good condition(i.e. no obvious damage) then I would be making a complaint to Gates directly, I am sure their engineers would be interested if there was a problem i.e. belts not meshing fully with a cam/crank gear...

There should not be an issue of the Gates belts not fitting in the cam gears. Gates make the majority of OEM timing belts for cars around the world (about 70%) so quality won't be an issue. I tend to agree with the gts4diehard, the racing timing belt is stronger and will not stretch as much as the original. This may mean that it requires a different tension to the original.

I would love to know if anyone has an actual figure of what the tension should be for the timing belt. I have the service manual and it just says something like "tension timing belt to the correct tension". That is pretty usless info as I can't find anywhere what the correct tension is. It has the tensions for the accessories belts but not the timing one.. stupid.

I had my timing belt changed to a gates racing belt by a tuning shop and it hums intermitently. I also had the tensioner, idler, adjustable ex cam gear, and water pump changed at the same time. It is no good that so many people have experienced this.

according to EN-26 in the 32 gtr service manual it is 196N (20kg) whatever that means.

So some of u r suggesting to throw away a good belt that is brand new and freshly put on the engine... Big deal it makes a bit of a noise. Save urselves the embarressment at lights and sell ur R33 .. If any1 asks u have a gates timing belt, most of the bogans next to u in the VN commodores would be impressed by that if u bought ur car to impress other ppl. From the read it sounds like it is very common with the gates belts. I am just getting one installed myself by a workshop who use them on track cars... If they were that shit I don't they would be used for track purposes on pretty modded engines.

I've got one. Makes a slight humming noise but it's no big deal. I can't hear it much with my exhaust anyway. I think it adds to the cars character

[T04GTR]

if it hums its to tight.

if it thuds its to loose

[T04GTR]

the alen key slot is there to lift off the tensoner when servicing. not to be used to tighten it. the spring does that.
