Aula F75 Wheel Teardown & Customization: Modding the Volume Knob Step-by-Step

An insightful review of Aula F75 Wheel Teardown & Customization: Modding the Volume Knob Step-by-Step—check out the essential highlights.

Enthusiasts who dislike the stock wheel's loose resistance can modify the encoder's internal feel. Two primary paths exist: non-destructive mechanical tuning or complete hardware replacement through desoldering.

For basic smoothing, apply a tiny drop of high-viscosity synthetic lubricant, such as Krytox GPL 205g0 or Super Lube synthetic oil, directly around the collar where the metal post enters the encoder body. Avoid standard spray lubricants like WD-40, which degrade surrounding plastics and dissolve contact grease. Turning the wheel twenty times disperses the lubricant across the internal detent spring, silencing scratchy sounds without wiping out tactile feedback.

To address a loose stock feel, the encoder's four metal crimp tabs can be gently tightened. Using fine needle-nose pliers, squeeze the corner housing tabs inward by a fraction of a millimeter. This tightens the internal disc against the tactile spring, eliminating unwanted vertical play.

If you prefer crisp, heavy steps, replace the factory component entirely. The stock board accepts standard TTC or Alps Alpine 11mm, 12mm profile rotary encoders. Desoldering requires a temperature-controlled iron set to 340°C, 360°C along with quality solder wick or a vacuum pump. Modders must clear all five electrical solder pads and the two structural chassis anchors simultaneously. Overheating the board risks delaminating the solder pads from the multi-layer PCB, permanently disabling volume control traces.
