The following work was done..

• Armstrong Lyon were called in to trouble-shoot the problem with the hydraulic system.
• We sent out a qualified site engineer.
• Extensive tests were carried out by a site engineer.
• Tests showed that the pump was failing and needs replacing.
• Due to production requirements the customer could not release this unit.
•  An identical redundant hydraulic power unit was provided for us to modify.
• We identified and sourced an alternative pump to the same specifications as the original, as the original pump was on a long delivery.
• The power unit was brought back to Armstrong Lyon workshop and stripped and thoroughly cleaned.
• The new hydraulic pump was mounted onto the tank and piped up.
• The power unit was thoroughly tested and passed.
