Recall 19V484 affects 94 2018 Mcneilus Bridgemaster V Mixer vehicles for an incorrect filler neck check valve that can overpressurize the tank. Free repair at a franchised Mcneilus dealer.
Mcneilus is recalling 94 2018 Bridgemaster V Mixer concrete trucks under recall 19V484 because an incorrect filler neck check valve installed during a prior recall repair can seal the hydraulic tank too tightly. The over-pressurized tank can rupture, spraying hot hydraulic fluid and plastic debris, and Mcneilus dealers will replace the valve for free.

What's wrong?
The filler neck on a McNeilus Bridgemaster V concrete mixer sits on top of the hydraulic tank. It holds a check valve that lets air move in and out as fluid heats up, cools down, and shifts during operation. That venting keeps internal pressure inside the tank's design limit.
These trucks were already repaired once under recall 18V-322. The corrected part has a longer neck before the valve seals and five vent holes instead of one, so pressure has more room to escape. The supplier shipped the wrong filler neck to some customers during that earlier repair. The incorrect part seals the tank too tightly, so pressure builds with nowhere to go and the tank can rupture.
There is no warning sign before failure. The only reliable way to confirm the right part is installed is to look into the filler neck and count the vent holes. One vent hole means the incorrect part is in place. Five vent holes means the corrected part is installed.

What's the safety risk?
A ruptured hydraulic tank can spray hot fluid and throw plastic debris, causing burns and injuries. On the road, spilled fluid and tank pieces become a hazard that raises the risk of a crash for the driver and nearby vehicles. Watch for any sign of a hydraulic leak around the tank and stop driving if the tank shows damage. Repair is free at any franchised Mcneilus dealer.
What should I do?
- Check your VIN to confirm your 2018 McNeilus Bridgemaster V Mixer is included in this recall.
- Contact a franchised McNeilus dealer to schedule the filler-neck inspection and, if the wrong part was installed under recall 18V-322, the free replacement that prevents the hydraulic tank from overpressurizing and rupturing.
- Reference recall number 19V484 when you call so the service desk pulls the correct repair instructions.
- Call McNeilus customer service at 1-888-686-7278 if you have questions about the inspection or repair scheduling.
- Keep the mixer off the road until the filler neck is inspected, since a ruptured tank can spray hot hydraulic fluid and plastic debris.
What happens at the repair
At the dealer, a Mcneilus technician inspects the vehicle to confirm which filler neck was installed during the earlier 18V-322 repair. If the part is incorrect, the technician replaces the filler neck with the correct component. Parts and labor are free under the recall. If you have already paid out of pocket for related filler neck work, Oshkosh's standard reimbursement plan covers documented expenses. Bring your receipts and prior repair paperwork to the service desk when you arrive, and reference campaign 19V484 so the team can match the work to this recall.
