Sorry if this isnt the right place for my quiestion. Does anyone have the part# on a k24 surpintine(sp?) belt. Its in an 02 civic without PS or AC just the idler pulley. We tryed the belt off our k20 eg but the difference in the k24 deck height makes the belt too short. TIA

its a cell phone pic.....my bad

Nevermind i figured it out. The k24 has a larger diameter crank pulley than the the type s, so if you use the type s pulley the type s belt will work.

hey actually, that is a good question, i had a k20, now going k24 and i plan on squeezing all the power i can out of it so no power steering of a/c. is it hard to change the crank pully? my motors will be side by side next week to compare and swap out intake manifold and stuff so i will try it, just wondering how hard it was and what is the part number for that, no p/s or a/c? i would really appreciate it.

BUMP Does anyone know what kind of belt you could possible get for this setup?

 

[nikos]

It is very simple in my opinion. You take string and you measure how long you want it to be.. Then you see if that belt is available in 7 rib.

For example,

if you need 39 inch belt (used only for 3 pulley setup) then you need

the Dayco 5070390 Belt http://www.partsamerica.com/ProductDetail.aspx?mfrcode=DAY&mfrpartnumber=5070390


for 41 inches : Dayco 5070410

Serpentine Belt: 63/64" x 41" 7 Rib

for 50.5 inches
http://www.partsamerica.com/ProductDetail.aspx?mfrcode=DAY&mfrpartnumber=5070505

and so on.. Not all sizes are available.

 

[civictype-s]

wow that is very helpful. when you say 3 pulley belt, is that basically crank, alternator and tensioner? no power steering, no a/c?

 

[nikos]

Instead of using the idler pulley, you can also use only 3 pulleys but you would need to buy the AEM pulley which is bigger in order to use a 7 rib belt.

Here's the setup with 4 pulleys ( with the Civic Si idle pulley)
length is 50.5 inches. You can get it at Kragen. The belt part number is 5070505.

the 7 = 7 rib
505 = 50.5 inches

and parts for the pulley are

pulley 31190-PRA-000
bracket 31175-PRA-000
washer 31185-PCX-003
bolt 90031-PRA-000


Here's the setup with 3 pulleys ( with the AEM pulley)

belt can be bought from advance auto
rib 39 inch belt. (rsx has 7 ribs but Supafly is using 6)

Part number is POLY COG 5070390

 

[civictype-s]

i have aem pulleys actually already so thats good news. that second pic looks like you arent using the tensioner. how did you get the belt on? is it very tight?

thanks for all the good info. :up:

 

[turboeg]

So no one has found a belt that works on a K24, using a idler pulley and a K24 pulley ? No PS, no AC.

 

[bossman032]

bump for answers asap. tia

 

[nikos]

You can try 44.5 inches

http://www.partsamerica.com/ProductDetail.aspx?mfrcode=DAY&mfrpartnumber=5070445

or 42.5 inches <--- That will work most likely

http://www.partsamerica.com/ProductDetail.aspx?mfrcode=DAY&mfrpartnumber=5070425

 

[bossman032]

this is the belt I bought.

http://www.partsamerica.com/ProductDetail.aspx?mfrcode=DAY&mfrpartnumber=5070675

setup like the picture above :down:

 

[nikos]

That is 67.5 inches... damn!! Are you sure you are routing the belt the right way?

edit: I got the wrong belt. I got the stock RSX type S belt for that car... :down:

Won't this throw the balance of the crank off?

 

[RhdRicheeee]

You can get it at Kragen. The belt part number is 5070505.

the 7 = 7 rib
505 = 50.5 inches

or the local checkers part # is 4070505

 

[94ex-vtec]

To answer the original question, the belt to use on a stock K24 with NO A/C and NO PS with the EP3 idler pulley is a 52.2 inch belt. This was covered in another thread somewhere and the overall agreement for the setup i listed above was 52.2 inches. I bought one the other day at Autozonedown: ) for like $12.99, the part # is 522k6. Only thing is that it is a 6 rib belt instead of the factory 7 ribs, however nobody that i know of has yet to find a 52.2 inch belt that is has 7 ribs anywhere.
