Crankshaft Repair


what is crankshaft repair:

crankshaft repairs are a type of engine repair that involves fixing or replacing a damaged or worn crankshaft in an internal combustion engine. the crankshaft is a vital component of an engine that converts the linear motion of the pistons into rotational motion, which powers the vehicle.

crankshaft repairs can be necessary for a variety of reasons, such as damage from overheating, corrosion, or wear and tear from normal use. some common symptoms of a damaged crankshaft include engine vibration, unusual noises, and poor performance.

the repair process for a damaged crankshaft typically involves removing the engine from the vehicle and disassembling it to access the crankshaft. the damaged crankshaft is then inspected to determine the extent of the damage and whether it can be repaired or needs to be replaced.

if the crankshaft can be repaired, it may be machined to remove any damaged areas and then polished to restore its smooth surface. in some cases, a new crankshaft may need to be installed if the damage is too extensive or if the crankshaft cannot be repaired.

overall, crankshaft repairs can be a complex and costly process, but they are necessary for ensuring the proper functioning and longevity of an engine. it is important to have any suspected issues with the crankshaft inspected and repaired by a qualified mechanic to avoid further damage to the engine.

Repairing crankshafts utilizing the grinding process allows us to maintain tolerance of the crankpin and main journal in terms of taper and ovality strictly as per manufactures specifications and tolerances.

If your crankshaft has the following defects we recommend having the crankshaft repair and grinded if.

  • Crankshaft increases in ovality and develops taper in the crankpin and main journal.
  • Bearing marks or pitting on the crank pin or crank journal.
  • Loss of alignment onto the crankshaft due accident or engine failure will require straightening and repair.
  • Grinding and polishing of worn out diesel engine crankshafts, mining equipment, pump shaft, alternator shaft, crankshaft, forging crankshafts, turbine shaft motors etc.
  • We offer crankshaft grinding and repairs to all industries. shipping companies, power generation, steel production, petro chemical, cement plant, mining and more.
