Recall 16V624 covers 2 2016-2017 Midwest All-Poly 2500 and 3000 Series fire trucks for a shift-unit defect. Repair is free at Midwest dealers.
Midwest is recalling 2 2016-2017 All-Poly 3000 Series and All-Poly 2500 Series fire trucks because a damaged component in the Waterous split-shaft transmission shift unit can keep the operator from changing power output. If the truck cannot switch from driving to pump operation at a fire scene, it can delay water delivery and increase injury risk; Midwest dealers will complete the repair free of charge.

What's wrong?
The transmission in the 2016-2017 Midwest All-Poly 3000 Series and All-Poly 2500 Series fire trucks is a split-shaft unit. It routes engine power either to the wheels for driving or to add-on equipment, such as the water pump used during fire response. The shift unit is the control point that changes where that power goes.
On affected trucks, C20 and C21 Waterous transmissions have a damaged component inside the shift unit. When that component is damaged, the operator can lose the ability to switch the power output. That means the truck can be stuck in the wrong operating mode for driving or pumping until the transmission is repaired.
There is no warning sign before failure. The first sign is the operator being unable to change the power output when the truck needs to drive or run the pump.
Who's affected?
Covers two All-Poly series across the 2016 and 2017 model years, all tied to the manual transmission component.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
A power-output failure can leave the fire truck unable to shift into pump operation after it reaches a fire scene. The crew can arrive without the water-pumping function needed to help extinguish the fire, increasing injury risk. If the truck has trouble changing power output, remove it from response duty and call the dealer. Repair is free at any franchised Midwest dealer.
What should I do?
- Check your VIN to confirm your 2016-2017 Midwest All-Poly 3000 Series or All-Poly 2500 Series fire truck is included in this recall.
- Contact a franchised Midwest dealer to schedule the free shift-unit repair, replacing the clevis pin and retaining rings so the transmission can switch power output.
- Bring the recall notice if Midwest mailed one. If not, reference recall number 16V624 when you call.
- Keep the truck out of fire-response service if the transmission shift unit will not switch power output.
- Call Midwest customer service at 1-800-344-2059 with questions about the repair.
What happens at the repair
At the dealer, a Midwest technician removes the shift unit assembly, then replaces the clevis pin and retaining rings in the Waterous split-shaft transmission equipment. The replacement parts and labor are free under the recall. Midwest has a general reimbursement plan on file for eligible out-of-pocket repairs paid before the recall notice. Bring documentation for any related prior repair and ask the service desk or Midwest customer service how to submit the claim.
