How to Remove Crankshaft Bolts with Primitive Methods?

[LeSophie]

Insert two steel bars into the holes, then use a pry bar to leverage the two steel bars to loosen the bolts. Alternatively, measure the hole distance and weld an F-shaped wrench. Below is an introduction to the crankshaft: 1. Introduction: The crankshaft is the most important component in an engine. It receives the force from the connecting rod and converts it into torque, which is then output through the crankshaft to drive other engine accessories. 2. Function: The crankshaft is subjected to the combined effects of centrifugal force from rotating masses, periodically varying gas inertial forces, and reciprocating inertial forces, causing it to bear bending and torsional loads. 3. Requirements: The crankshaft must have sufficient strength and stiffness, with journal surfaces that are wear-resistant, operate uniformly, and have good balance.
