Quick answer

Unexpected wear on cylinder neck mounting blocks has been found on certain Agility Fuel Solutions ("Agility") tailgate compressed natural gas ("CNG") systems supplied to McNeilus for use on front end load ("FEL") refuse vehicles. Agility CNG fuel systems using sliding block cylinder neck mounts must be checked visually for Delrin bushing wear and threaded block wear at regular intervals to prevent cylinder damage. A detailed physical measurement of sliding block bushing gaps should be performed at the following intervals to confirm evidence of excessive movement or play: Severe Duty - Every 15000 mi. (24140km) / 1000 hours; Medium Duty - Every 75000 mi. (120700km) / 3000 hours. If gaps greater than 1/16-in. (1.6mm) between the cylinder neck and threaded block or Delrin bushing are present, examine the cylinder necks for wear, and replace worn neck blocks and/or bushings. Agility urges McNeilus FEL fleet operators to perform CNG system inspections and maintenance at the regularly recommended intervals.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
