On Site Crankshaft Grinding- Process, Inspection, and Repair

 

Introduction to On site  Crankshaft Grinding - RA Power Solutions

On site crankshaft grinding is a vital process to keep engines running smoothly and lasting longer. This precise technique restores the crankshaft’s dimensions and surface, helping to prevent engine breakdowns. This easy-to-follow guide covers several steps to successfully grind a crankshaft onsite, suitable for both professionals and Crankshaft repair workshops.

In this guide, you'll learn the steps from preparation and inspection to polishing and reassembling the crankshaft. Mastering these techniques will help you boost engine performance, avoid expensive repairs, and extend the engine's life. Follow these steps for effective, accurate onsite crankshaft grinding.

Instead of taking the crankshaft out of the engine and shipping it to a workshop, technicians come to your location and perform the work there. RA Power Solutions provides specialized, portable equipment to grind, machine, and repair the crankshaft right onsite.

Inspection of Crankshaft on site

Start by cleaning the crankshaft with a suitable solvent to remove dirt, oil, and debris. Check for visible damage like cracks, grooves, or excessive wear. Use a dial indicator to see if the crankshaft is bent or misaligned.

Common Issues to Look For-

During inspection, keep an eye out for:

  • Cracks: Use a magnetic particle tester to spot tiny, hard-to-see cracks. Serious cracks may require a replacement.

  • Wear: Look for worn spots that might require regrinding. Check taper and ovality.

  • Scoring and Grooves: Deep marks or grooves can be from poor lubrication or debris, and may need further repair.

  • Heat Damage: Discolored or blue areas can mean heat damage, which affects strength and requires careful grinding.


Preparing and inspecting the crankshaft well helps ensure a smooth grinding process and keeps the engine in top shape.

Polishing and Finishing

After grinding, polishing removes tiny rough spots, reduces friction, and improves durability. A polished crankshaft helps the engine run smoothly, retains oil better, and reduces early wear—critical for high-performance engines.
