Belt Won't Tighten

[Sipey]

OK Chaps

Since fitting the Prolex manifold, my supercharger belt will not tighten. I can push the tensioner as far forward as poss and the belt is still slack. Took it off and put it on again and tis still the same.

Why could this be??

Sounds like you've re-fitted the charger slightly differently to when you had it on previously if all other things being equal (ie. it was tight before).

[Sipey]

but it only goes on one way don't it Zee mate

make sure you have the tensioner on the right side of the belt

[Sipey]

Tensioner is on the right side of the belt mate - as in the belt is on the right hand side of the tensioner.

only ask as seen one installed on the left with the same result of not tightening

[Sipey]

Could the belt have stretched or does it need replacing? Are there any shorter ones available?

[Bazza]

no it wont have stretched

is there any numbers on it ?

where did it come from ?

[Sipey]

Same belt that came with the kit bazza mate.

Put some chimes under the frame of the supercharger. Where it connects to the manifold...

chimes = washers

Done that mate and it warps the cradle so you can't bolt the charger to it

do u mean the front RH bolt for the SC? this is a bit tricky to get in on mine

[Sipey]

Any bolt mate. If you put a washer in between the cradle and the manifold it distorts the cradle. I could force the cradle to bolt the charger on but do not want it to snap under the stress and vibration when driving the car.

If you think all will be OK, I will put the washer back. I know that with the washer in place, the belt would probably tighten up. I thought at one point last night I had the belt tight but on inspection I had the belt over the edge of the pulley, so a 2mm or 3mm washer would probably take up the slack

Which brings me on to a thought - Dave or Matt. Is the plate of the manifold thinner than the original as this is the only thing that has changed.

When i fitted the prolex manifold, i had not problems with the belt :D

Did not use any washers at all :D

[Rob]

i was thinking the manifold flange might be thinner, that might explain it a bit better

Tis what I was thinking mate

[Sipey]

Still unsure as to why the standard belt will no longer fit but have sorted it out by purchasing a shorter one. All would appear to be OK now

Many thanks for your suggestions :D
