What is the installation method for automotive eccentric bolts?
2 Answers
Eccentric bolt installation method: First, align the protruding part of the copper piece outward, with the shorter side tightly against the inside of the eccentric bolt, then tighten it. Detailed explanations about the functions of eccentric bolts are as follows: 1. Eccentric bolts are commonly used in automobiles, and their installation does not increase the stress on the lower bolts. 2. Eccentric bolts are primarily used to adjust the camber angle of the wheels and the height difference between the left and right wheels. 3. Eccentric bolts mainly adjust the four-wheel alignment, utilizing the physical principles of inclined circular rotation and friction to secure mechanical components. 4. If the wheel camber angle exceeds the standard usage range, adjustment using eccentric bolts is necessary to ensure normal wheel data, effectively avoiding tire wear.
I've installed eccentric bolts several times before, the kind used for adjusting the suspension system. The necessary tools include a jack, wrenches, and a torque wrench. After lifting the car and removing the wheel, locate the installation position. The bolt is eccentric, so extra care is needed to align the holes properly—don't force it. Clean any grease or dirt around the bolt holes to prevent dust from affecting the adjustment and causing loosening. After installation, hand-tighten to initially secure the position, then use a wrench to adjust to the precise angle. It usually takes several attempts to align the center correctly. Once the position is confirmed, fully tighten the nut with the specified torque wrench. Don’t forget to lower the car afterward to measure the wheel track and take a short drive to check for balance, avoiding severe tire wear or steering wheel vibration later. Regular maintenance of the front wheels is recommended, and when replacing bolts, inspect surrounding components like bushings for signs of aging. It’s not difficult but does take time.
