Re: Emergency Change Order — Nortax PO #126247 — Repair Excavator
Pursuant to 5-90 (G) of the NRO, I have authorized an emergency change order for the repair of
the excavator at the Four Hills Landfiii in the amount of $18,893.21 to Purchase Order #126247
with Nortrax.
Nortrax originally quoted the replacement of the hydraulic pump coupler in #30 the John Deere
270D Excavator used at the Four Hills Landfill for loading demolition into trailers for transport.
The Nortrax technician removed the hydraulic pump assembly to replace the hydraulic pump
coupling. During the removal and inspection process it was found that the hydraulic pump shaft
was cracked from the catastrophic failure of the hydraulic pump coupling. When the shaft
cracked internal damage to the pump occurred contaminating the hydraulic system.
Specifically, this change order will provide for the items listed below:
Replacement of the hydraulic pump to be completed by Tuesday, May 16, 2016.
Nortrax is the New Hampshire dealer for John Deere Equipment and has the field equipment
and trained technicians to replace the pump, coupler assembly and clean the hydraulic system
at the landfill and avoid further charges for low bed transportation to Pembroke.
