Message: [QUOTE="mandkole, post: 529662, member: 4630"] Good luck, but you can't eyeball pulley groove profiles. Just using a simple tracking groove that contacts the belt base of the rib, the belt will slip-- I guarantee it. To carry load, Micro V belts need an optimized groove contact surface area or tons of tension. Ive learned from my 25 years in this business, there is a lot of science in the belt/pulley interface. (this is our accessory drive on the MX 13L in the avatar picture.) My suggestion is to find a machine shop that has SAE specifications and can cut 'K' section belt grooves, or find a balancer that is already done. I may be able to find some drawings in the next day or so if it would be helpful. [/QUOTE]
