Cylinder Liners

We maintain large stock of refurbished cylinder liners of popular high capacity  make and models of engine. The cylinder liners are calibrated in our workshop and we guarantee for the satisfactory performance and the long life of the cylinder liners. We refurbish and supply the cylinder liners which have minimum wear and tear and have high residual life. The cost of refurbished cylinder liners is almost one third of the new cylinder liner supplied by OEM. Thus it results to the considerable savings.

New cylinder liners are available in stock. We also develop and manufacture new cylinder liners as per the drawing and samples provided by the client. The cylinder liners manufactured by us are cast by latest centrifugal casting equipment which ensures uniform grain structure. The final machining and honing of cylinder liners is done in-house. The cylinder liner bore and all critical dimensions are maintained strictly as per the tolerances mentioned in the drawing.

We are regularly exporting  cylinder liners to various companies all over the world including UK, Finland, USA, Nigeria, Singapore, Malaysia, Sudan, Canada, Mexico and several countries in Asia.

We depute our technician on board a vessel with necessary instruments to inspect connecting rods.

Crankshaft Grinder

Insitu Crankshaft Grinder

The table type crankshaft grinders are outdated as they need huge investments and large area for installation.

Onsite crankshaft grinders are manufactured by RA Power Solutions Pvt. Ltd. having range from 60 mm to 700 mm and it caters to the engines having the capacity of 30 MW. The crankshaft grinder are portable light weight and easy to operate. The crankshaft grinder can be taken to the site.

Grinding and polishing can be done without removing the crankshaft from the engine block. The crankshaft grinder are low priced and highly recommended for shipping companies and repair workshops. More than 60 crankshaft grinders have been sold.

                                                  

Metal Stitching and Metal Locking Process

It is highly recommended to undertake repair of crack castings of engine block, cylinder heads, turbine casing and cast iron parts by metal stitching and metal locking process.

Metal Stitching-Locking Process

 

It is a cold process, no stresses or heat is generated. RA Power Solutions is undertaking crack repair by metal stitching and metal locking process for last more than 3 decades and have executed more than 500 projects successfully all over the world.

We have highly skilled engineers who can easily perform metal locking and metal stitching process on following make of engines: MAN-B&W, Sulzer, Wartsila, Mak, Deutz, Pielstick, Mitsubishi, Nohab, Daihatsu, Yanmar, Bergen, Crepelle, Niigata, Himsen, Allen, Stork, MWM, Hanshin, Caterpillar, Ruston, Paxman, Mirrlees, Alco, Fiat, ABC, Crepelle, SKL , etc

Rebabbitting of White Metal Bearing

Manufacturing of Motor Bearing

Rebabbitting of white metal bearing is required when the bearing develops taper, ovality and white metal is worn out. Rebabbitting of white metal bearing up to 1500 mm bore size is undertaken by RA Power Solutions. All the parameters like presence of cracks, hard spots in steel lining are checked prior to doing rebabbitting.

The selection of grate of white metal is done based on the load characteristics of the bearing, RPM and application. The rebabbitting of white metal is done by centrifugal process. This ensures strong bonding between the base metal and the white metal. All the bearing are subject to dimensional inspection and bonding by ultrasound process.

Rebabbitting of following bearings is undertaken:

a.  Turbine Bearing
b.  Alternator Bearing

White Metal Bearing

c.  Engine Bearing
d.  Pedestal Bearing

Used Cylinder Heads

Cylinder Heads

Cylinder heads of Wartsila, Paxman, MAN-B&W, MWM, Sulzer , Mak, Deutz, Mitsubishi, Caterpillar, Daihatsu, Bergen, Himsen, Allen, Stork, Fiat, SKL, Ruston, Crepelle, Mirrlees, Alco, Crepelle, Yanmar,  Pielstick, Hanshin, Nohab etc are available in stock.
 

The used cylinder heads are procured from the power plants and ship breaking yards and they are transported to our works. Cylinder heads are subject to crack detection test by MPI procedure, valve seat and valve guides are replaced wherever required.

After reconditioning cylinder heads are subject to hydraulic pressure test. We can also supply new cylinder heads.

Insitu Rotor Shaft- Inspection, Grinding and Polishing

 

Onsite Rotor Shaft Grinding and Polishing

Rotor shaft is mainly placed on white metal bearing. Due to continuous running it is observed that taper, ovality and rough surface is developed. It is important that during the major overhauling or after certain hours of operation as suggested by manufacturers rotor shaft is inspected.

RA Power Solutions has technicians who are qualified and experienced t o undertake onsite inspection of rotor shaft, alternator shaft, turbine shaft, alternator shaft and pump shaft. The rotor shaft inspection broadly includes crack detection by magnetic particle inspection (MPT), hardness check and dimensional inspection. In case any abnormalities are observed, RA Power Solutions technicians undertake onsite grinding and onsite polishing of rotor shaft maintaining tolerances and surface finish as per the manufacturers.
