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

    • Have you put an aftermarket oil pressure gauge on and verified your oil pressure?   Noise being on the block, on exhaust side, how high up the block does it seem to be? It could be the VCT system getting cranky, especially if it's mainly at idle, and when warm, as that'll be your lowest point for oil pressure. Could be showing that oil passages / VCT solenoid are blocking.
    • Well, hydraulic lifters will get noisy if they are dirty/fouled in some way, and exactly how that manifests will depend on exactly what schmutz is where. There is a procedure on here somewhere for dismantling and soaking/cleaning them. Replacing them with new is about 50% of the work and about 5% of the money!
    • Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers  
    • This seems problematic and unlikely at the same time. Vanilla RB2Xs have hydraulic lifters. They do have "zero" clearance, but only when running with oil pressure inside them. When not running, you should be able to compress them and obtain heaps of clearance. RB26s and Neos have solid lifters. They should have ~0.3mm and ~0.5mm on the inlet and exhaust respectively. If they have zero clearance then bad things are happening. With nothing else being wrong, it would mean that the valves would be held slightly (ever so slightly) open when they are supposed to be closed and it should have all sorts of problems when running, caused by leakage in/out through the valves. Or, zero clearance can indicate severe valve seat recession. None of it is good. Have you used a piece of hose as a stethoscope to try to localise the noise?
