Description
John Bean 20024335 Nylon Mount/Demount Duck Head for EHP System IVE / IV / III / IIE Tire Changers – Pack of 3
The mount/demount duck head (duckhead) is the wing-shaped nylon component at the tip of the tire changer turntable arm that contacts the tyre bead during mounting and demounting operations. Because it is the direct interface between the machine and the wheel, it is the part most subject to wear. Replace when the nylon shows visible cracking, chipping, or deep grooves. Before ordering, verify that your machine already uses a plastic/nylon duck head; if your machine is fitted with a metal head and you wish to convert, a separate adapter bracket kit is required.

Fitment & Ordering Notes
These heads are a direct replacement for machines that already use the plastic/nylon duck head system. If your John Bean tire changer is equipped with a metal mount head, you will need a conversion kit that includes an adapter bracket and hardware – this listing covers the nylon head only. Always confirm the existing head style and the machine model number against your parts manual or a qualified technician before ordering to ensure compatibility.
Additional Product Information
Nylon duck heads eliminate metal-to-metal contact between the machine arm and the wheel rim, significantly reducing the risk of scratching or damaging alloy and chrome wheels. The nylon construction is resilient enough to handle the bead break forces of larger passenger and light truck tyres. The pack-of-3 quantity allows a complete head change or provides on-hand spares to minimise downtime.
