CRV crank pulley belt

Im getting ready to install my CRV crank pulley on my 2000 gsr and I was wondering if I needed a different size belt. Can I still use my stock belt or do i need a bigger/smaller belt?

thanks.

Yep new belts for PS, AC, and Alt. I am about to change my crank pulley as well.

I don't have my files currently, but a search on the archives will find this question answered many times. (By me usually!)

Holden, I did a search and was unsuccessful. Can you tell me what size belts i need. THanks.

I know that the alternator to crank belt will be a 4PK850(mm) or 335K4(inches)... the other two I am not sure of. Don't quote me, but I believe the A/C is ok to re-use, and the P/S needs to be 1" shorter than stock.
You can simply measure the differences in the pulley diameters at each belt location and then calculate the circumference of the pulley... then add or subtract this amount from that of the original belts.

I agree with Jim on the Crank-Alt. belt. 850mm

The Power Steering belt you want is 900mm.

You may be able to use the AC belt by greatly tightening the belt via the tensioner, but a smaller than stock (790mm) belt could work better.

You are going to need a different belt, but I am not sure which one though.

I haven't put an AC belt on in years, so I don't know exactly, but the AC pulley on the CRV pulley is smaller than on the GSR pulley, so either the belt must smaller or the tensioner must tighten things more.

Thanks guys.

So i need a smaller than 790mm for the AC or will a 790mm work fine?

Holden and Jim,

I went to the local honda dealer today and they didnt have those size belts. They said that they only go by application not the lenth (i.e. 850mm). My question now is, where can I obtain these belts? Also, do I specify the belt for CRV or GSR? Are the belts for the CRV and GSR different or are they interchangable?

Thanks.

Find an auto parts store where you can get to the belt rack. Know the following things:

- 25.4mm = 1"
- Belt numbers, the ones printed on the belt itself, indicate the length and rib count. e.g. 4PK900 means 4 rib, 900mm. 345K4 means 34.5", 4 rib.
- Some are marked in standard. Some in metric.
- Know both versions of the belt you want.

... I should mention that the counter clerk at the parts store will be confused. Don't worry. Just be nice and ask to go to the racks!

And I just thought it was my local clerks that were lost when you asked for anything to custom size. My 92 GSR AC is smaller than the CRV's by quite a bit, must be 94+ GSR's. I hope the Alt. pulley is the same size. Thanks for the good info Holden.

I should take my own advise!

I just shoehorned a 330K4 belt onto my car for the alternator.

It was freaking difficult, but tightening was still needed. Barely!
