HOW TO: Unorthodox Pulley Install & Belt Sizes - Page 4

NX2KTPR · 06-28-2008, 05:23 PM

Install the pulleys.
Measure with string how long the belt should be.
Go down to the auto parts store with the old belt and say "I need a belt like this but with a length of X".
If they can't figure it out, go to a parts store that knows what they are doing.

That should be true as the PS and Alt. are OEM sized. If not I my mind has gone.

Thanks for the help.

So they are the same if you run A/C?

^What is the deal on this washer you speak of? Anybody else know about this?

I will be running all 4 UR pulleys with A/C like you. What belts do I need sr20 91-SE-R?

I have full UR pulleys on my '91 B13, belts may still be readable for the part # since they were new last year. I had to replace my alt (not related to UD pulleys, just old) and with a lot of adjustment the same belt works with the stock pulley - I still can't get the UR pulley OFF the old Alt, it's welded on there with age.

If you're stuck on belts still drop me a PM and I'll check. This thread is very dead.

^Back Alive

^PM sent..........Others were copied on it as well. The links in the first post are dead. I need to order my belts. Soon as I get a cherry picker, I'll be ready to roll. Google links lead me back here. I'll see what I have stored in my hotmail account.

SuperblackZ · 08-28-2008, 04:55 PM

Ok, the PM just sticks an e-mail where I'll remember to do it

I'm sure I have the alt gates belt number because I bought a spare before driving the car from CA to CT, and Dave C put new belts on Jan 2007, I have A/C, and Crank UD pulley for sure.

SuperblackZ · 08-28-2008, 07:32 PM

Lower belt (wider 6 groove serp belt) has a series of numbers across the belt:

4060390 6PK990 Goodyear Poly-V

Which is alt, A/C, crank pulley, all UR pulleys

Upper smaller belt (inner crank, PS, WP) is Goodyear Poly-V , here's the numbers:

4040342 then 4PK870

There's a decent Xref here for Gates and others :

HTH & good luck!

I got a PM from a couple of you, It has been too long, I dont remember the belts I used. Just use the old string trick to measure

MR-4Door-SR20DET · 09-03-2008, 02:25 PM

^I found these belts from a google search, they should work find. Can someone double confirm for me? The Gates Belt part # K060390 from the RockAuto site says 39-3/4" instead of 39-5/8". Will it still be ok?

okay i know this thread been dead for a little but i was just wanting to know since i have a 1993 sentra with the upgraded pulleys on my sr20det with AC -
I need the goodyear poly V 4060390 and 4040342 - I thought we needed 3 belts on the sr20det with AC,, or do i have to get one belt twice,.,.,. ?

Thanks,,.,

SuperblackZ · 12-19-2008, 09:19 PM

1x Serp Belt

4060390 6PK990 Goodyear Poly-V

Which is alt, A/C, crank pulley, all UR UD pulleys except A/C in my case:

GATES
K060390

DAYCO
5060390

GOODYEAR
4060390

METRIC
6PK990

The Upper smaller belt (inner crank, PS, WP) is Goodyear Poly-V on my car, here's the numbers:

4040342 then 4PK870

2 belts total, those numbers should help.

Some other information that people might find useful is that on my auto 99 G20 with AC (2 pulley set) the belts that I used and that [work] well are CarQest Micro-V K060390 21mm x 1000mm and K040340 1.4mm x 880mm .

what's the website for that belt?

TUF TF040340

Dayco 5040340
Goodyear 4040340
Cadna 340K4
Metric 4PK865

The second one is a Gates Belt, you should be able to find that multiple places, e.g. RockAuto, etc. like here:

http://www.autopartswarehouse.com/sk...%26+Drivetrain

UR recommends the Gates belts for some reason unknown to me, it's in their install instructions. I have a Goodyear for the serp and a Gates for the other so clearly both work (but pls note I'm not using this size, see my earlier posts).

thanks for the links guys. now I can buy my belt

burubuduy · 02-04-2010, 02:57 PM

just installed my belts on my Gspec crank pulley and used Goodyear Gatorback 6PK0990 in my alternator and 4PK0850 in my P/S and it all fit good.

MrBojangles · 10-11-2011, 05:48 PM

I am replacing my Crankshaft Pulley for my 1997 200SX SE-R.
Is there any tools I need before I take off the pulley? Anything I need to know to keep it timed right? I am afraid to take it off and screw up the timing of the engine. Please help.

NX2KTPR · 10-11-2011, 11:07 PM

You can't put the new one on wrong since the pulleys are "keyed" to line up in the right orientation.
