Is someone able to give me the correct part numbers for all three drive belts for my S2 Stagea (aircon, alternator, power steering)

Recently as part of my 100,000k service I bought a set of drive belts. The local gates dealer supplied me with

4PK835R

4K865R

4PK925R

(I ordered gates racing belts)

When my mechanic did the service he said they didn't fit and the belts on it are at the end of the adjustment. The belts on it currently he said are

4PK865

4PK890

4PK910

I had a quick look on just jap and the numbers they list are

3PK840

4PK855

4PK915

Which are the correct numbers? Please help, no searching is coming up with anything lol

The 4 stands for 4 ridges/ribs. The last numbers stand for the circumference.

If the mechanic said to get 10mm shorter

4PK865 = 4PK855

4PK890 = 4PK880

4PK910 = 4PK900

Mine were replaced a while ago. I just checked them and they are the same as what the mechanic told you you have on your car.

I just noticed something too ( see attached pic) - On the Alternator/Waterpump Belt (890) I am only using up less than 10mm of the adjustment and have a shitload to go. A 4PK880 would be a bitch to put on.I would say your mech. wants 10mm shorter because the current ones are stretched. That's just what happens over time.

Basically, Do what KiwiRS4T said :)

Yeah that's why the mechanic said its near the end of the adjustment. The belt shop gave me a 4PK925R to fit where a 4PK910 should go so he couldnt adjust it enought to fit.

It does seem that the belts currently on the car are the ones I need and are the standard stagea length because they're the same as what's on other peoples stagea's

    • looking forward to your t56 swap man its a game changer if it works! 
    • So, when are you trying the new GR86 or BRZ?
    • Uncle Duncan Yeap, FI Interchiller  Works well, normal IAT's cruising with the WTA only went from 50°c+ to 25-30°c with the interchiller  Before, when on it hard, the IAT would see 80-90°c, now, the highest has been was around 38°c IIRC IAT is measured under the blower hat I recommend it for the street or strip where your only on it hard for 10 or so seconds, but it wouldn't be efficient for sustained track use as it would heat soak from the AC turning off or whatever it does during WOT to protect the compressor It really needs the AC running for it to not heat soak and keep the WTA coolant chilled My WTA coolant temps when just cruising is around 2°c
    • Hey Mark...sorry to interrupt your career change to hair dressing... but...did you ever fit the interchiller to the commodore, and if so how was it? And, who made it?
    • I've been pondering this, I really enjoy the convertible thing, for me, it's like riding a motorbike, without all the issue of riding a motorbike, mainly, my old sore arthritic joints getting beaten up, and, being able to do it in shorts and a T-shirt and not needing a helmet and all the other gear required, especially like wearing jackets and pants in the summer, or needing 6 layers of cloths in the winter, or not having wet weather gear handy when your 100km away from home on the bike when it decides to start raining As for the hard top and its Coupe look, whilst I do lose all that open top feeling that I really enjoy, from my experience with the NB with a detachable hard top, the cabin is a much nicer place to be, the difference in noise for one, a hard top quietens down the interior, alot, with the soft top up or down it's pretty noisy, which, after 5 or so hours, can get tiring But, as you stated, the detachable hard top totally changes the look of the car, in a really good way, and for me, the look of a detachable hard top is so much better than the PRHT which looks more like a after thought with its weird bulbous rear roof line For me, the minimal effort of putting in on, or storing it after removing it, is well worth the time and effort for the look alone And yes, I'm sure the next owner will be grateful for it as well.......
