What belt size is needed with a 270 upper and 6# lower?

TIA

 

Odin,
If this pulley setup is the same as you were running before, the same belt should work. I am running a 2.8" upper and 5# lower with the same belt. The instructions say you need 1" larger belt but that's not the case(at least for me)....JR

BTW I am running a 67.5" Gatorback

 

Thanks JR.

I had to knock the tab off the tensioner to get my current belt to fit. I'm gonna need a little bit more belt; but, I didn't want to over do it. I guess an inch longer will do it.

How much are these idlers? Did you notice a difference at high RPM's. Who makes a 2.7" upper?

TB

 

The Magnum Powers blower comes with a 270 upper. I haven't installed the idler yet. I'll have it on in the next week or so.


Price

 

REM sells a 2.77 and a 2.84 upper set or individually.

I just noticed that JLP has a 2.7" upper pulley made of aluminium. That has to be the smallest that you can fit on the snout of the Eaton.

Did Metco come out with a different idler kit design? This looks different than what I saw before. Is it better?

TB

 

it's a new "universal" design...works on the MP and KB also

 

Is it better? Sturdier? Lighter? Cheaper? What does it look like compared to the old one?

Here's a pic of the new design:


I got it from chikenears:

Don't have a pic of the old one but this one looks like a much better fit...it doesn't mount to the SC like the old one. The other one had long bolts and plates to mount it.

 

Anyone else selling those ?

Apperently chikenears dont sell there products outside the US !

 

I use the new Metco Idler w/ 100mm idlers. This required a 1" larger belt for me. I also run a 2.7" upper from JLP. It fits over the stock eaton snout with no grinding, but is definately a tight fit!

 

Amp where did you fab that radiator shroud... that is very nice and do you know where I can get one as well

 

I made it myself.
