SAFETY NOTICE

VSR-TSB-027-Inspection Information

NHTSA Campaign Number: 19V-656

Vehicle Safety Recall – Technical Service Bulletin

Attention:	McNeilus Customers
Subject:	Pressure Relief Device (PRD) on CNG Tank
Models Affected:	McNeilus Refuse Rear Loaders, Front Loaders, Side Loaders, McNeilus Rear Discharge Bridgemaster Mixers and Standard Mixers, Aftermarket Parts sold for non-McNeilus vehicles fitted with Emcara PRD valves on the CNG tanks
Date Revised:	October 2019

Purpose:

McNeilus Truck and Manufacturing, Inc. has been alerted by our supplier that a concern affecting safety exists in some Emcara Pressure Relief Device (PRD) valves on CNG tanks (for your information, Emcara’s NHTSA Recall number is 15E059). Some McNeilus models were shipped with an Emcara

CNG PRD which may not vent properly. The purpose of the thermal PRD is to relieve pressure in the CNG system if the CNG tank is reaching an unsafe level of pressure, as might occur with a thermal event that heats up a tank. In the event of a thermal event, the thermal PRD may not vent properly, which increases the likelihood of a CNG tank over-pressurizing and rupturing. A tank rupture creates an increased risk of injury to the truck occupants, firefighters, or bystanders.

Affected Vehicles:

The affected vehicle population is PRD valves fitted on tanks assembled by McNeilus between 2013 and 2018 and are PRD valves with serial numbers between LB00001119 and LB00003999.

Time Completion:

Affected units shall be repaired using McNeilus qualified service technicians – at no cost to the owner. The time of accomplishment may vary due to a number of factors; however, the estimated time for completion of the procedure is 1.0 hour under normal circumstances.

Required Action:

Review and verify the ownership of all affected serial numbers of trucks. If McNeilus records indicate the owner of one or more affected units, a Serial Number List is enclosed. Please be reminded that it is a violation of Federal law for companies to sell or lease the CNG systems or vehicles that use CNG systems covered by this notification until this recall has been performed on these vehicles. Substantial civil penalties apply to violations of this law.

A McNeilus Service Technician will inspect each vehicle that has tanks assembled in the affected population range.

Contacts:

If you have questions or need further information, please contact a National Service Representative at 888-686-7278.
