Crankshaft webs connect the main or intermediate journals to which journals?

• A. The connecting rod journals
• B. The piston pin journals
• C. The timing gear journals
• D. The camshaft journals

Answer: (A)

Crankshaft webs serve as the rigid links between the crankshaft’s main journals, which sit in the engine block bearings, and the crankpin or connecting rod journals, where the connecting rods attach. The webs provide the structural bridge that keeps these journals properly spaced and aligned while carrying bending and torsional loads as the crankshaft rotates. The other journals mentioned belong to different parts of the engine (piston pins on the piston, or gear/cam components), so the webs are not connections to those journals. Therefore, the webs connect main or intermediate journals to the connecting rod journals.
