Those are measured deflection numbers...i.e. the how stiff the limbs are. The higher the number; the stiffer the limb.
Each bow as a sequence of where the stiffer limbs need to placed; for Evolve cam bows; the stiffer limbs go on the cable side; spread of 5-7 on top and 2-3 on bottom.
So the sequence for that particular set of limbs on an Evolve cam bow would be as follows for a right hand bow:

135-140
136-138

The work on both right hand and left hand bows; but the sequence is mirror image because the cable side is on the left for a left hand bow; like this:

140-135
138-136

 

Great information thank you!!!

 

125-122
118-125


One thing I did notice when I got back home. The #12 limbs currently mounted on my Left Hand bow are arranged as follows:

((Looking from the string side of the bow as if in a shooting position))

----------------Top
Left Side---125-122---Right side
-------------118-125
--------------Bottom

So should that mean the new limbs should be arranged?:

----------------Top
Left Side---140-136---Right side
-------------135-138
--------------Bottom

or

----------------Top
Left Side---138-136---Right side
-------------135-140
--------------Bottom

Cables are mounted on left side of one cam and go to yoke to the other cam.

Your current limbs are in the wrong sequence...i would be surprised if that bow was able to be tuned at all.
The sequence i put in post #2 for a LH bow is the correct one...
Did you get the bow used?

 

Lol yup it’s used, just got it in. Hmmm...well I was planning on getting a Synum bow press so I guess this decides it.

 

I am the previous owner of the Focus XL. The limbs are in the sequence as it was built at PSE. Yes, the bow did tune just fine. I was able to set some NFAA Outdoor Target National record scores with it.
I would call PSE with the serial number and ask for the limb sequence for the EM cam.

 

My intent wasnt to cast blame (sorry if it came across that way); I was just trying to answer the OPs question on how to sequence his new limbs. We have had several come from PSE with the bottom limbs reversed thats why i asked the question. As far as the limb sequence, what i posted above is correct. Sure; PSE can be called but bear in mind the customer service folks likely dont know much about tuning or the engineering of the bows, better to get that info from folks who live and breathe this stuff.
