i see there is 2 different set ups of aux belts that the cossies came with on various models etc

a 2 belt system for water pump and power steering etc and a multi rib single belt?

whats the better option?

its for a 200block 4x4 engine but im buying all new alloys puuly's so can choose what to run

thanks Marc

 

ive heard a few people say that the tensioners on the ribbed belts nack up and they are dear to replace.

 

If I had a choice even though I'm on single/twin belt I'd go for multi ribbed everytime.

Poly V (multi V) belt is better all day long.

Better grip and longer life.

 

i thought the reason for the twin belt setup meant that it couldnt slip? as both would have to slip at the same time
no idea which is better tho

 

i think i remember rod mentioning that the twin belt set up is no good at high rpm & he is running the multi groove belt system

 

there is a reason why cars dont generally have crappy toothed belts on em anymore...... your telling me you dont miss the "SQUEEEEEEEKKKKKKKKKKKK" in the rain pulling out of corners that used to happen,,,,,, then SNAP

poly V is def the best option, more grip and longer life too

 

i dont know mind ginge ive heard a lot of the v belts squeak too. It must be better cause ford wouldnt of changed it on the cossies.

 

Twin belts were just a pain in the arse

 

Yes thats correct at sustained rpm ( 8k+) the Power Steering belt would turn over & hit the cooling belt, we ran without the outer belt on Topspeed runs.

 

What do you have to change to go to the multi groove setup?

 

Need to change the pulleys, ie crank, alt, water pump, ps pump.
I can't change as my trigger wheel is locked/welded to my crank pulley.
Saying that I've never had any slippage in the wet, but do have to hunt a bit for two belts when replacing them that are the same width, even ones of the same make can vary in width, as most makers actually just buy them in and box them, plus multi seem to last forever as well.

Does anyone have pics to compare the two belt styles and
pully's?

Thanks Marc

 

Tabs, I assume all the pulleys are just a simple swap over, no different bolt hole alignments or anything silly like that?

Or you could get all new anodised pulleys for the 4x4 and put them in a 2wd?

 

Transits are on v belts and they all squeak badly

 

Any belt will squeak if its not tensioned/maintained correctly

 

Here is the small turbo escort setup fitted to my saph, much neater and better than the 2 belt setup:

 

not running power steering wes?

 

The big pulley on the bottom left is the power steering pump. The spare set of grooves on the front of the crank pulley is for an air con pump which i don't run

 

To change over to the later ribbed type belt, you will need the main bracket that goes on the offside side of the block, tensioner, all the ribbed belt pulleys, and power steering pump pipe (the power steering pumps are on opposite sides). I'm pretty sure the pumps are the same.

 

anybody got a pick of the multi ribbed belt but on an engine with the power steering on the nearside and no air con

thanks
Marc

 

i dont know if anyones done it but thats how i was going to go on my escos

as far as i know you need a ribbed belt pulley for crank, water pump and alternator, you will also use a 2wd alt bracket and tension it like you would ona twin belt system

the p/s pump would be v belt and need to be spaced out to keep it inline with the front of the crank pulley as this would use the v groove on the crank usually for aircon

 

i had the later style multi v belt on my facelift cos never had any problems with it.

 

make up the multirib but without that fooking massively heavy bracket - you can still have a manual adjuster on poly v setup.

 

What bracket mark ?

 

its what i saidm you will use a 2wd alt bracket and tensior bracket, so its a multi ribbed belt but you adjust as if it was a twin belt set up

 

i reckon you could use one of marks Alloy units as per the 2wd, fit all the std poly v pulleys - you dont have to have auto adjusters - not like your trying to do 2-,40k miles on it without maintenance.

 

Will use all alloy pullys and brackets and Will also be using wrc alt bracket so it mounts at the bottom and swings out at the top so I can fit a bigger better alt

 

do you need more than 90amps to run your car? thats a lot of current pal. dont go over spec for no reason.

if you work out you need it then by all means by a smaller version with the same output

 

Can you get a multi ribbed belt as shown above but one that only goes from crank to water pump to alternator? i will either run the power steering on the other side with a single v belt or i will be running electric power steering so will have no power steering pump or belt

thanks
Marc

 

I looked into it Markk and no i do not need that much ampage so i will be running a 2wd alternator/bracket/tensioner set up

Plus the cost of a grp a alternator bracket is ridiculous!

 

The crank pulley in the picture is a T25 36-1 escort cosworth varient.

Dunno if that helps?

 

what i want is a crank pulley with multi rib on the inside and v belt on the outer side,

Im gonna be getting a billet pully from mk motorsport so im sure he could do this for me with a 36-1 trigger ring on the back.

Just need to know if i can get a multi ribbed belt that just does crank/alt/water pump

 

yes you can get any length of belt you like measure it uo and go to a local motorfactors will have one on the shelf, i have had to do a few conversion and have never failed to get a belt

 

Iv just recently dropped off some 4x4 pulleys to Chris of CDF racing Marc, im sure he would do what you want bud.. not to far from us either, infact i pop in there from time to time.

 

the pas pump is differant(i know cause i need 1 and cant find 1 local for my 4x4)
and the pipes are differant to and need changed when converting from old spec to newer spec

 

all the bling cost lots of money pal ! whether you need it or not is what you need to decide, looking good does not always mean going fast !

as for the belt setup, yes you can get a belt and a pulley, the std 4x4 has both iirc. (just not the 36-1/2)

 

Iv been thinking more and more about getting the multi v belt set up converted to run the 2wd way!

 

2wd and 4x4 Pas pumps are the same part.

 

What do you mean with that big heavy fook off tensioner set up?
