In 1977, the Allis-Chalmers 7000 series was updated. The frame color was changed to black, and the cab was replaced with the Acousta Cab II. The gear levers were moved from the floor to a side console, and the noise level dropped by a couple of decibels. The 7040 was replaced by the more powerful 7045. The transmission options still included the Power Director with a 2-speed quick shift and the Power Shift with 6 speeds. The hydraulics were load-sensing.

The smallest model in the series was the 7020, which had the previously used 4.9-liter inline-six engine with an intercooler, now producing 146 hp. The standard equipment on the 7020 was pared down, removing features such as ether starting, foot throttle, and telescopic steering column. One range was left out of the transmission, so it had 16+4 gears. In 1979, the older technology-based 7000 model was replaced by the 7010, which had its power reduced to 118 horsepower. In 1978, high-clearance versions of the 7020, 7045, and 7060 models were introduced.
