Ok so i brought my belts to Orielly to see if they could find some interchangable ones with doubts in my head. I only had my Alternator and A/C belts on me because my power steering one got lost some how. So I used the part number for the power steering belt that was given in the part number thread for a Daco belt and they found a match for that too but had to order it so i wont have it until tommorow.

Anyways the Alternator and AC belts fit perfect so here are the part numbers:

Alternator Belt: Gates K040335A/C Belt: Gates K040378Power Steering: Gates K030328 (unconfirmed but should fit)

Anyways I couldn't find any info on the belts so i thought this might help some people.

these have been confirmed by another memberAlt- K040335A/C- K040358P/S- K030328-kamin

Excellent! I have been able to find the A/C and alternator belts but I've been searching for a PS belt for what feels like forever! Lemme know if the belt you bought works so I can replace mine as it's almost completely shredded.

RB26DET w/ RB25 crank pulley, and power steering pump.

I'm sure the gates PS belt mentioned above will work, but what does everyone think about using the RB25 belt for the alt?

i imagine it would be ok. the pulley on the alternator is so small, its probably the same size and a similar distance. try it out and see! let us know the results. i'll prolly be doing something similar

I broght all three of my accessory belts into NAPA last fall to get them replaced, but I don't remember the belt sizes they "matched" them to. They weren't exact matches, but they were close enough to easily get them on and tension them properly. I'll look at them this afternoon over lunch and let you know.

If any of you are unlucky enough to end up with a RB26 power steering pump on RB20/RB25 (you'll know cause every single other belt # mentioned will be too short -- and the PS pump pulley is 4 rib while your crank pulley is 3 rib) here's what you do...

Go get a 90-96 300ZX N/A power steering pump belt! It's a 36.5" 3 rib belt, also used on the Q45 and J30. Gates PN is K030365. Fits perfect and you shouldn't have to slot your PS tensioner at all.

cheers

My setup: RB20, RB25 crank pulley, RB20 ps pump bracket/tensioner, RB26 pump

Are you running rb25 with what a/c pump? With rb25 pump, where would get the a/c lines done? I would ask you the same if you are running ka pump.

This info is for RB26 but figured I'd post this here since this is the very first thing that come up when I google "rb26 belt sizes". Found this info on gtrcanada forum and its real useful.



"Now keep in mind that the 4 is the rib count and the 880 is the lenth in METRIC.
Make sure you do the conversion or your belts you get will be huge.


alt - 4PK 880= 345
ps - 4PK 925= 365
ac - 4pk 950= 375

Now these are rounded up numbers typically belt lenths gouo in .5 inches. Napa will get close if not exact to thoes numbers."




You can go to any autozone and pick up any of there, they're usually in stock.

Cheers.

For the rb25 p/s you can get a 2005 scion xB power steering belt. Worked perfect for me. Was able to get it at advance auto also so no wait. :bigthumb:
