Onsite Man B&W Crankshaft Grinding


RA Power Solutions offers specialised onsite MAN B&W crankshaft grinding services for industrial machinery, power plants, and marine diesel engines all over the world. With five decades of experience in crankshaft grinding, repair, and reconditioning, our engineers handle crankshaft damage without removing the crankshaft from the engine block. We have developed efficient repair techniques for various working situations thanks to our hands-on training at crankshaft manufacturing and grinding facilities in Europe and the USA.

While assisting in the restoration of crankshaft journals within OEM specifications, onsite machining minimises the need for disassembly, transfer, and lifting. This strategy is especially helpful for industrial facilities and ships where reducing equipment downtime is crucial.

Onsite Crankshaft Repair and Reconditioning Services

The main and auxiliary engines of MAN B&W operate under demanding conditions. Crankpins and main journals can be harmed by bearing failure, inadequate lubrication, overheating, and high friction. Engine operation and bearing performance may be impacted if the damage is not properly evaluated and fixed.

Crankpin grinding, main journal grinding, crankshaft polishing, dimensional inspection, and associated machining procedures are all part of our on-site crankshaft repair and reconditioning services. We use mobile on-site crankshaft grinding machinery that is made to operate directly on engine-installed crankshafts.

Crankpin and main journal widths ranging from 60 mm to 700 mm are covered by our equipment. In situations where limited access makes traditional machining challenging, special-purpose tools can also be created. Restoring the damaged surface and dimensional accuracy without unnecessary engine dismantling.

Onsite Insitu Crankshaft Repair for Marine Engines

An efficient substitute for removing a huge crankshaft and relocating it to a workshop is onsite insitu crankshaft repair. Heavy lifting arrangements, thorough disassembly, and extra logistics may be needed for crankshaft removal, which could increase both repair time and cost.

Our professionals perform machining directly on the mounted crankshaft while using in-situ crankshaft grinding. After evaluating the damage, material condition, journal size, and relevant manufacturer constraints, the repair method is chosen.

Journal scoring, wear, and bearing-related damage are all addressed by our on-site crankshaft grinding services. The impacted crankpin or main journal is ground and polished to the necessary dimensions based on the inspection results. The engine is equipped with appropriate undersize bearing shells that match the final journal diameter when needed.

Inspection and Technical Accuracy During Crankshaft Grinding Onsite

A crucial component of on-site crankshaft grinding is accurate inspection. Our engineers inspect the crankshaft prior to machining to assess the degree of damage and spot any issues that might interfere with the repair.

The following could be part of the inspection process:

  • Hardness testing: Using portable hardness testing equipment, determine how hard the damaged area is.

  • Crack detection: When necessary, use Magnetic Particle Testing (MPT) to find surface and near-surface cracks.

  • Dimensional measurement: It includes measuring the diameters of the main journal and crankpin and verifying the taper and ovality.

  • Crankshaft deflection checks: Assessing crankshaft deflection in accordance with the engine manufacturer's protocol.

  • Measuring the Ra surface finish: Following grinding and polishing is known as surface finish verification.

  • Fillet radius inspection: Verifying that the fillet radius stays within the designated bounds.

These inspections assist our engineers in choosing the best repair technique. To aid in the repair procedure, inspection results and pertinent measures are recorded.

On Site Crankshaft Repair Without Removing the Crankshaft

Our on-site crankshaft repair process makes use of portable equipment made to operate in engine rooms. Modern machinery reduces setup time and the possibility of alignment faults brought on by frequent repositioning by grinding and polishing the crankpin or main journal in a single configuration.

Our professionals keep an eye on crucial dimensions and surface finish during the on-site crankshaft machining process to ensure the necessary tolerances are maintained. Before the repaired journal is approved for service, the final measurements are compared to the relevant OEM requirements.

Special-purpose tools can be made to fit the limited workspace in situations when access is restricted by engine block apertures or other components. Every repair is carried out by our skilled specialists under the guidance of a senior engineer.

After technical evaluation, in-situ crankshaft straightening may also be carried out via a controlled pinning procedure in appropriate circumstances. When the condition and repair requirements allow it, this can offer an option to replace the crankshaft.

Onsite Crankshaft Maintenance Services for Different Industries

We provide on-site crankshaft maintenance and repair for industrial, power generating, and marine applications. Our professionals provide on-site crankshaft and crankpin machining for a variety of engine types and rotating machinery in addition to MAN B&W engines.

Our offerings include:

  • Crankshafts of the main and auxiliary engines

  • In situ grinding of compressor crankshafts and compressor shafts

  • Rotor and turbine shafts

  • Shafts for motors

  • Cylindrical shafts and other parts of rotating equipment

Equipment owners can handle machining needs at the installation site with our crankshaft repair and grinding services. We determine if onsite repair is technically feasible based on the component design and damage.
