Connecting rod repair

We offer connecting rod reconditioning/refurbishment for all four stroke engines,
with as well as without serrations.

Upon receipt, all connecting rods are cleaned and inspected.
Connecting rods are then crack tested with magnaflux for crack detection.

Connecting rod repair services – scope of repair:

• Machining and refurbishment of connecting rod
• Magnaflux testing to determine invisible cracks and damages
• Machining and restoration of damaged serrations
• Internal machining of big end and small end bores to remove ovality
• Retesting after machining with magnaflux
• Accuracy and finish achieved as per OEM specifications
• Survey by class society – upon request (LR, DNV, ABS, BV, NK, GL or other)
• Packing and preservation

All repairs are conducted by CNC erosion technology, providing the best possible finish on serrations, enabling fast deliveries regardless of make and type.

This is secured by no requirement for special tools, and no time loss due to positioning of arrangement.  

Example For Sulzer ZA40 Big end bearing we offer reconditioning as follow:

Cleaning and crack test with magnatoflux.
Machining of mating surface between upper and lower part and mating surface for rod (if necessary).
Shot-peening of the mating surfaces between the upper and the lower halves.
Machining of big end bore back to standard.
Final crack test and measuring report.
Shot-peening of the big end bore.
All work carried out acc. Sulzer ZA-5 bulletin.

One of our new european service areas is honing of cylinder liners.

Honing becomes necessary, when rings and liners are suffering from wear and missing honing pattern.

With our Gehringer honing machine, cylinder liners with a diameter of 150 mm up to 450 mm can be machined.

Gehringer honing machine specification
Stroke.          :  1500 mm
Bore....          :  0 - 450 mm

Upon receipt each cylinder liner is cleaned and the inside diameter measured.
We carry out control of all o-ring grooves, check of landing surface and sealing surface.

The liners are then honed to re-establish liner geometry of the entire running surface and thereafter final check measurements is taken together with roughness measurement (Ra)  

A report of the work performed will be provided upon completion.

If the initial control of the cylinder liner indicates that reconditioning is not possible, the liner is rejected, and the customer will be informed, and new liners will subsequently be quoted.

All liners packed in wooden boxes (not included in list prices) in accordance with ISPM 15 standard for world-wide transport.

Honing of liners for four stroke engines is carried out in our workshop facilities in Scandinavia / Europe.

Piston crowns often exhibit wear, particularly within the piston ring grooves, which inevitably leads to over sizing and often scrapping. PJ Diesel and their partner have developed a proven method to recondition used piston crowns back to standard at a fraction of the cost of a new unit(s).

On receipt at our works, all piston crowns are thoroughly cleaned, degreased and identified with a unique reference number to ensure traceability.

A full inspection report is produced, including photographs – And sent to the client for approval including recommendation for repair.

Upon receipt of approval from client, the piston crown(s) is machined to remove all existing chrome and prepared for hard chrome plating of the ring grooves.

Hard chrome plating of all over size ring grooves is then completed.

This is followed by precision re-machining of the ring grooves, and all critical areas to the original limits and tolerances, carried out in own state-of –the-art workshops.

The piston crown is then clean and complete.     

Piston skirts can be fully reconditioned at PJ Diesel and partner, our unique service offers aluminium weld repairs back to original manufacturer standards at a fraction of the cost of a new !

On receipt at our works, all piston crowns are thoroughly cleaned, degreased and identified with a unique reference number to ensure traceability.

A full inspection report is produced, including photographs – And sent to the client for approval including recommendation for repair.

Upon receipt of approval from client, the piston skirt(s) is then machined to remove all existing defects and grooves if oversize in preparation for the aluminium weld process.

The aluminium weld process is then carried out to the defective areas.

This is followed by precision re-machining of the ring grooves, and all critical areas to the original limits and tolerances, carried out in own state-of –the-art workshops.

The piston is then clean and complete.
