YUCHAI ENGINE Connecting Rod Bolt 1DQ000-1004054
FUNCTION
1. High-Strength Locking (Ensuring Micron-Level Roundness and Preventing Bearing Seizure): By applying immense preload force, the connecting rod body and cap are rigidly joined; this ensures that, under high-speed rotation, the large-end bore of the connecting rod remains free from deformation-thereby preventing oil film rupture and the resulting catastrophic failure caused by bearing seizure.
2. Resistance to Tensile Forces: At the precise moment the piston reaches "Top Dead Center"-transitioning from the exhaust stroke to the intake stroke-the bolts must instantaneously withstand reciprocating inertial tensile stresses reaching several tons; they firmly secure the assembly, preventing the connecting rod mechanism from tearing apart or disintegrating during high-speed operation.
3. Precision Positioning: The high-precision, unthreaded shank section located in the middle of the bolt acts as a precision dowel pin; it establishes a micron-level interference fit within the connecting rod bolt hole, thereby completely eliminating any lateral misalignment or shear-induced oscillation of the connecting rod cap, and guaranteeing absolutely uniform load distribution across the bearing shell.

Replacement Recommendations
1. Replace Upon Exposure" Rule for Major Overhauls: Once initially tightened, the internal metal structure of the bolt undergoes irreversible, microscopic plastic deformation. Therefore, if an engine undergoes a major overhaul involving the removal of the cylinder head cover-or if the connecting rods are disassembled for any reason-the bolts in question *must* be mandatorily scrapped and replaced with new ones. Reusing these bolts a second time is strictly prohibited.
2. Connecting Rod Bolts Must Be Replaced in Pairs: The two bolts on a single connecting rod collectively determine the load-bearing equilibrium of the rod's big end. If one of these bolts becomes stripped or damaged, both bolts on that specific connecting rod must be replaced simultaneously; replacing a single bolt individually or mixing new and old bolts is strictly forbidden. During a major overhaul, it is recommended to replace the entire set of bolts for the vehicle (typically 8 or 12 bolts) as a complete unit.
