i want to install this honda n1 crank pulley on my jdm b18c, but i need to know the correct belt size. i've searched and these are all the different answeres i've found:

CTR N1 Crank Pulley Belt Part Number:
Autozone belt number: 290K4 (extended p/n is 4PK735)

4PK 755
4PK stands for 4 ribbed
755 is 755mm

The part # is 56992-P1R-004 Acura 2.5TL power steering belt

acura TL alternator belt also works

goodyear belt size number 4pk735

it's the same part number as the alternator belt for a 94 acura vigor

the belt you need is a 655mm belt with 4 grooves

it's close to 25 3/4"

...::sigh::.. so if anyone has put this pulley on their b18c & is 120% positive of a certain belt size please respond. i don't need anymore "pretty sure" answers.

 

yup bump dizzle

 

I did not realize the the NI was also under driven.

So same question for me, for it would be on a 18B. Maybe the same size as the 18C??

thanks

 

couldnt you use the b16 belt? I dont get it, its what I have, I could get the number for you... Sounds like youve boughtin a lot of belts!

 

..bump

 

isnt the N1 alternator only?
i guess im mixed up

 

yea.. no a/c or p/s.. just crank to alternator, but it's underdriven slightly

 

I have an N1 pulley as well. What do you mean "slightly underdriven?"
Now, i put mine on, and the tdc is not really lined up as well as i wish it would be. It is like, 3 mm off,not enough that it can be corrected by skipping a tooth. is this normal or did i mess something up. Is it pulley a little off? also, just a simple question... I put my timing belt on today.. how tight should i tention it?

 

dude.. what a thread jacking

 

sorry... no jacking intended

 

guess no one knows for sure

 

Damn, no real answer.

Have you tried either the PS or AC belt??

I think mine will go on next weekend if the weather stays nice.

Maybe just go to pepboys or sometihng and see if anone will look for a belt the is about 655mm and just use the tensioner to pull it tight. Thst is if it is within a couple of MM

 

well i'm putting mine on tonight & i just went to autozone and bought a 735mm belt. looks good by just eyeing it, but i'll let you know how it fits when i get home from work.

 

Bump for an answer, i sell these on ebay and it would help if i knew what belts people should buy and maybe include them in the auction as well

 

Why would you need a non-OEM size belt? Wouldn't it be the same belt as OEM???

You can adjust the tension on the alternator to accomadate a dif size belt. Are the serpentine grooves dif on the N1? I would think they would have to be same as stock or else you'd need a different alternator.

I have an ATI Damper on mine and it uses all the stock belts and is lighter then the OEM Damper too.

 

found the correct belt.. made a new thread here: https://honda-tech.com/zerothread?id=1171612
