thank you for making this Dave.

So is the new Si crank pulley the one to go with now? now TSX/CRV?

[chronic si]

Isn't the R40 A02 the same as the 08 accord crank pulley?

[Steve42790]

What about rdx cp?

[JDM_DOHC_SiR]

The RDX Pulley 13810-RWC-A01 is similar in size to the R40 pulley... not to sure on exact DIA but it's lighter than the R40 one by quite a bit...and it's rather cheap too ....
looking to find more info on this pulley

lol can u go measure the diameter of ur crank pulley

[mucter]

[mucter]

It's raining like the end of days outside.

[mucter]

And the outer diameter is not what you need. You need the diameter where the ridges are that the belt runs on. It's impossible for me to get you that without taking the belt off. Which will never happen on that car.

i found it online from acura for $28?! its that cheap??

[mucter]

That's funny if it's only used on the RDX. The RDX didn't exactly sell in high volumes.

Thats about the price they sell for 28~39$

Buy it and measure it for us .... measure it from Peak to Peak on where the belt rests.. so we can add a pulley to the line up if it's different

Also looking at adding the Monster 4G TL pulley to the line up if there is anyone crazy enought to use it
