Reusing crankshaft bearings is possible if they are in good condition and have proper oil clearance. However, they must be thoroughly inspected for wear, damage, and correct measurements. While reusing them can save money, it carries risks, such as reduced engine performance or shortened lifespan if the bearings are compromised. Crankshaft bearings are vital components … Read more

A crankshaft journal size chart provides detailed dimensions and tolerances for the crankshaft journals in specific engines, including main and rod journals. It helps ensure proper bearing fitment, correct oil clearance, and overall engine balance. This chart is essential for engine builders and mechanics to maintain optimal engine performance and longevity. Crankshaft journals are critical … Read more

Crankshaft journal measurement is crucial for ensuring the proper fitment of bearings, maintaining oil clearance, and preventing engine vibrations. Accurate measurements help detect wear, taper, and out-of-round conditions that can affect engine performance and longevity. Using precise tools like micrometers and dial bore gauges ensures the crankshaft operates smoothly and efficiently. Crankshaft journal measurement is … Read more

To remove a crankshaft pulley without a special tool, use a breaker bar or long-handled wrench to loosen the pulley bolt by securing it against a solid surface and briefly turning the engine with the starter motor. You can then gently pry the pulley off using a flat-head screwdriver or pry bar. This method requires … Read more

A bad crankshaft pulley can produce several unusual sounds, such as squealing or chirping, knocking or clunking, rattling or clicking, and grinding noises. These sounds often indicate issues like a worn bearing, loose pulley, or deteriorating harmonic balancer. If you hear any of these noises from the front of the engine, it’s essential to inspect … Read more

Yes, a crankshaft pulley can smoke, typically due to friction, overheating, or an oil leak. Causes may include worn or misaligned belts, damaged pulley bearings, or oil leaking onto the pulley.
