Crankshaft Repair Cost 

Crankshaft repair cost

Crankshaft is one of the main mechanical parts of the engine. Sometimes, same drivers can see that motor is not efficiency as the first time operating. If you hear someone knocking inside engine, it could also indicate engine crankshaft problems.  It would be appropriate to say about these problems now, but I suggest to begin with the main questions which will see in this article:

  1. Engine Crankshaft Problems;
  2. The main repair methods of the crankshaft;
  3. What influences the crankshaft repair cost?
  4. Crankshaft Services & Pricing.

Engine Crankshaft Problems

We started be saying that crankshaft is very important part of internal combustion engine. This part converts chemical fuel energy into motion. The crankshaft provides a nexus between engine and gearbox. When it crashes is not possible to avoid costly repair.

Usually, the crankshaft can be crashed by two main reasons: engine oil not enough or excessive engine loading. Most modern cars are not afraid last reason crankshaft crash, because vehicle electric system controls all engine functions. The electric system turns off fuel supply, if engine begins to work with excessive loading. 

Engine Crankshaft Problems

1 – Crankshaft flexing; 2 – wear of the outer surface of the crankshaft flange; 3 – run-out face plane of flange; 4 – wear of oil canals; 5 –  wear of  bearing  hole; 6 –  wear of flywheel bolts; 7 – connecting rod bearing and crankshaft bearing damage; 8 – wear of journals for  hub pulley and gear; 9 – wear of groove keyway; 10 – increasing the length of the front crankshaft journal; 11 – increasing the length of  crankshaft connecting rod journals.

The first reason is not enough of engine oil can be main reason of crankshaft problems. There is no oil between the parts which leads to dry friction. Effects of this problem can be connecting rod bearing damage, crankshaft bearing damage and the crash of crankshaft finally.

How to define that engine need crankshaft repair? It`s rule that problems of crankshaft have loud knocking.

The main repair methods of the crankshaft

Experience has shown that small sized crankshaft will be better for replace, but oversized crankshaft will be better to repair.  If this is the case will it be possible to achieve a comprehensive cost savings. Friction forces, vibrations, different loadings affects at the crankshaft in time engine operating.

This leads to crankshaft and connecting rod bearing journals wearing. So they have irregular wear: taper in length; ovality – in diameter; quality violation of bearing journals surface: notches, scratches or corrosion; mechanical damage: crankshaft cracks, thread defects; crankshaft deflection.  Exploration of someone crankshaft problems shown these are consequences fatigue of metals and internal stress inside.

In order to eliminate defects of crankshaft used repair technology bearing journals by repair size, grinding with the next polishing,   different kinds of surfacing and plasma spraying. Crankshaft flexing can be eliminated by the plastic deformation method.    

What influences the crankshaft repair cost?

Unfortunately, the repair of a crankshaft is very difficult process that can do professional only. It needs to do grinding of bearing journals on the special equipment.   Let`s go explore the main possible works by crankshaft repair.

Main types of crankshaft repair:

  • Grinding;
  • Dressing;
  • Polishing;
  • Crankshaft pulley repair;
  • Canal cleaning;
  • Connecting rod bearing replacement; 
  • Crankshaft Balancing.

Crankshaft repair is serious task, so it would have to be professional specialists and very expensive equipment. And you should not forget that dismantling the crankshaft also costs money. How much money does a crankshaft repair need?
