Not all Equaliser Bars are re-manufactured Equally!
J&S Engineering has been re-manufacturing and upgrading Equaliser Bars for more than 30 years. Over this time, we have developed robust procedures and operating practices to deliver ‘best of breed’ outcomes for customers delivering trouble free operations between overhauls.
Observations gathered over recent time continue to indicate that not all repairers have the necessary experience and protocols to deliver reliable products.
Our most recent example highlights a number of issues that ultimately lead to failures in the field and reduced operating life:
- Strong backs poorly fitted to the body and material thickness undersize.
- Fillet Welds undersize and poor quality
- No stress relieving of welds or inadequate stress relieving
- Bores not reclaimed properly or effectively
- Poor final machining
The outcome of these shortfalls includes:
- Fatigue cracking and failure of structural components
- Reclaimed bores delaminating
- Poor seal contact in the bore allowing the seal to walk out. The user often has to weld washers on the face of the equaliser to hold the seal in place however this practise induces cracking in the bar.
J&S Engineering integrated re-manufacturing services ensures these types of issues are prevented making Equaliser Bars go the distance and on-going overhaul costs are minimised through less re-work. An Equaliser Bar refurbished at J&S will have bores machined to OEM spec, if any welding was required the bar has been correctly stress relieved, the bar has been MPI and UTS inspected and passed by a third party approved company so quality is assured.
