Using the correct OEM bolt guarantees that the joint will behave as engineered, maintaining proper preload and alignment. For safety, these bolts are crucial in dynamic systems where failure could lead to loss of vehicle control or component detachment.
The BY90011400043 is specified for applications where standard hex head bolts with separate washers may not provide sufficient bearing surface or vibration resistance. Its use is a key factor in achieving the designed durability and safety margins of the vehicle.
During assembly or repair, using the genuine bolt ensures that the clamping force is accurately translated through the joint without compromising the fastened materials.
1. Ensure the threaded hole or nut is clean, undamaged, and free of old thread locker, dirt, or corrosion. Chase threads if necessary.
2. Inspect the new BY90011400043 bolt for any shipping damage or defects. Do not use a bolt with damaged threads, a marred head, or a cracked flange.
3. If specified by SHACMAN procedure, apply the recommended thread-locking compound or anti-seize lubricant to the bolt threads. Avoid contaminating the bearing surface of the flange.
4. Insert the bolt by hand to ensure smooth, non-binding thread engagement. Do not force the bolt if it does not start easily.
5. Using the correct size socket or wrench, tighten the bolt initially to seat the flange firmly against the workpiece.
6. Final tightening must be performed with a calibrated torque wrench. Tighten in a gradual, controlled manner to the exact torque value specified in the SHACMAN service manual for the BY90011400043 application.
7. For critical joints with multiple bolts, follow the specific tightening sequence (e.g., star pattern) to ensure even clamping and prevent distortion.
• During routine maintenance inspections, visually check critical fasteners, including the BY90011400043, for signs of looseness, corrosion, or head deformation.
• Use a torque wrench to periodically check the torque on safety-critical bolts, especially after the first few hundred miles following installation or repair.
