Shipping service Time
Expedited DHL WorldWide 2-5 business days
Material
Pulley (cam) made of Aluminum alloy 6082 T6 is a medium strength alloy with excellent corrosion resistance. It has the highest strength of the 6000 series alloys. Applications of 6082 is typically used in: Highly stressed applications, Trusses, Bridges, Cranes, Transport applications, Ore skips.
Coating/Finish surface
The ready machined parts goes through electrochemical anodization process to improve the durability of the aluminium alloy , after which color is added for aesthetics.

Explaned! How to install, TEXT and PICTURE.
Pic.1 - Unload the two springs.
Pic.2 - Take off the metal cap.
Pic.3 - Unscrew both.
Pic.3.1 - Take off the throttle plate.
Pic.4 - Take off the circlip and the nylon washer.
Pic.5 - Pull out the shaft.
Pic.6 - Remove the OEM plastic pulley.
Pic.7 - Fit the aluminium pulley and mark the holes.
The accuracy of the OEM stainless steel plate is +-0.2mm. The tolerance of those OEM plates are relatively in big range. Why they don't chase great accuracy? The answer is simple, cheap and fast production. The OEM plate is formed on a press machine and after that melted plastic is squeezed around the OEM plate to form the plastic pulley.
-----------------------------------------------------------------------------------------------------------------------
Pic.8 - Punch a center and use two drills to avoid dislocating the holes. As it's suggested first use 2.5mm drill and second use 4mm drill. Drill the OEM stainless steel on low rpm and lubricate! Start with a sharp drill and have it turning as slowly as your drill or drill press will allow. Set the drill press to its slowest speed or run the portable drill as slow as the trigger will allow. You need to exert pressure on the drill bit - as much as it will bear.
Stainless is actually a relatively soft metal, at least in its initial state. What stainless tends to do is “work harden” fairly quickly when heated, and drilling at high speed creates a lot of heat. When stainless steel work hardens, it becomes very hard and extremely difficult to drill.
------------------------------------------------------------------------------------------------------------------------
Pic.9 - Drilling 2.5mm holes.
Pic.10 - Drilling 4mm holes.
Pic.11 - Clean all chips after drilling the holes.
Pic.12 - Done! Nice and clean.
Pic.13 - Тighten all screws using threadlocker with high temperature properties or with greater properties. This is mandatory!
Pic.14 - Check for drops of threadlocker and clean if present.
Pic.15 - Return the shaft.
(Optional): Before placing back the shaft, clean the throttle body from fumes and oil debris by using detergent for carburetors. Apply oil on both bearing.
------------------------------------------------------------------------------------------------------------------------
Pic.16 - Place the nylon washer and the circlip.
Pic.17 - Return the throttle plate.
Pic.18 - Fit the throttle plate without applying force! Nice and easy, it will fit perfectly.
Pic.19 - Screw both.
(Optional) Use threadlocker low temperature properties.
Pic.20 - Place back the metal cap. Use only rubber tools to place it back and load the springs!
Pic.21 - First spring!
Pic.22 - Second spring!
Pic.23 - Done! Finished! Mission Complete! Enjoy increased lifespan and superior performance.
