Other Option For Timing Belt...

[nissan200sx.dk]

Hi all.

I bought the 152 tooth timing belt that Spool imports supply for the rb25/30 conversion.. But its not long enough... !! My fault not Spools!

I used the rb30det.pdf thats around to setup my tensioner pulley. Were its written in a picture were to mount the tensioner.

i need a other belt that is 2 - 3 tooth longer.. 4 -5 tooth will prob be okay also. Were and what can i use? I have looked in Dayco wepshop, and can see the tooth proflile for the belt used in the .pdf file is: STP8M (Dayco number 94407).

Can I use other tooth profile? Or is my only option the 164 tooth long belt? If still need to be STP8M profile...? Do you think i can use the 164 tooth belt??

Really hope someone can help me out here.

Can't you redrill and tap the hole for the tensioner stud (where it's supposed to go), so that the belt will fit?

That would be the easiest solution, if you can fix it...

I was hoping not to redrill..

But if there is no other solution i must

yep...thats what i would do...redrill & tap...a little bit of time saves wasting the belt and more money/time for another.

Just Jap in Sydney stocks a Gates belt that suits RB25/30 and RB26/30, they ship internationally as well.

[TiTAN]

he already has a belt to suit, just not the way he has positioned the tensioner

Try fitting an RB25/26 idler on the passenger side rather than using two tensioners, it will loosen the belt up quite a bit.

yes having two adjustble ones should get you out of trouble, must have adjustable cam gears so the timing is corect.

worst case you can try and find a smaller lower idler pully.

there is a company called econobelt. they will make you any belt you need. the more you buy the cheaper they are, i think they are around $30 usd for 1 if you buy 3 of them

i think Gate's rb25/30 specific belt is ur best bet !

I use a idler from my old CA18 on passenger side of engine, and rb25 tensioner on other side. This way i can get the belt on.

Is this okay??

[daisu]

If it fits should be okay, I wouldn't be using 2nd hand idlers/tensioners though

[fletch rb30]

CA series motors only run a 3/4 inch belt ~19mm wide, the rb belt is inch ~ 25mm wide. Are you sure your belt is not hanging over the side of the idler?? it will wreck the belt in minutes of running

[nissan200sx.dk]

There is 1mm overhang from belt to idler.. Will this ruin the belt?

[Jack88]

id think any over hang would ruin the belt,the walls of the idler would eat through the belt and destroy the teeth. Take a picture and post it on here so we can see exactly what your talking about.

[nissan200sx.dk]

This is the overhang there is..... Is this okay, or would it ruin the belt if i run the engine?

i would say that you will wreck the belt like that.

Can you get another RB tensioner? they are the correct width and also seem to be cheaper than the RB idler pulleys. Plus like proengines said, you can adjust it to suit

[nissan200sx.dk]

the first thing i tryed with was 2 x tensioners from RB.... that was a no go! The CA idler is smaller in diameter and made it possible to mount the belt..

[fletch rb30]

Looks liek you either need to re-drill and tap the top tensioner, or contact gates belts and get them to make you a custon lentgh belt. The next size they do in 8mm HTD is 164 teeth which is 96mm longer than the belt you have now and probably too long?
