Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.
ZFL-IB-003
McNeilus Truck and Manufacturing, Inc. has been notified by customers of an issue regarding the power steering system on the Volterra™ ZFL™front loader refuse collection vehicles. McNeilus Truck and Manufacturing, Inc. is working with the steering pump supplier to identify the root cause(s) and a corrective action. A future bulletin will be provided when a corrective action has been identified.
ZFL-IB-002
McNeilus Truck and Manufacturing provides updated Volterra ZFL Preventive Maintenance schedule and instructions for an initial (within 500 miles or 6 months of service) retorque of the front axle U-bolts to 500 ft.-lbs. and semi-annually or every 12,000 miles (whichever comes first) retorque of the U-bolts to 500 ft.-lbs. The vehicle’s service maintenance manual reflects the same update.
ZFL-IB-001
McNeilus Truck and Manufacturing provides instructions for installing an updated park brake valve pressure switch. The updated pressure switch has a higher pressure activation and reset values which reduces the delay experienced with the previous pressure switch and addresses an unintended door alarm.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
