About the Caterpillar AP-650B Asphalt Paver (9DN, A7P)

The Caterpillar AP-650B is a highly productive tracked paver engineered for exceptional stability and material flow control. Powered by a robust industrial diesel engine and featuring heavy-duty D3 track rails, the AP-650B excels on job sites with challenging terrain. This model features an exclusive gateless feeder and auger control system, which allows the two feeders and two augers to be controlled independently. This design eliminates the need for feeder gates and significantly reduces material segregation, ensuring a uniform mat across the entire paving width.

Maintaining a 9DN or A7P-prefix paver requires access to accurate factory specifications to manage its complex material handling circuits and hydrostatic propulsion. This manual ensures that every task—from adjusting the automatic track tension to rebuilding the electric-over-hydraulic steering—is performed to original equipment standards. Investing in this digital guide protects your machinery investment and ensures the reliability needed for high-quality asphalt production.
