The International Paystar F-5050 was introduced by International Harvester in 1973.

Model history

The International Paystar 5000 line was a series of extra heavy-duty construction trucks intended for use as dump trucks, cement mixers, oil-field trucks, etc. The Paystar line replaced the M-series and the 210-230 series. It included various models with 4x4, 6x4, and 6x6 drive arrangements, powered by gasoline, mid-range diesel, and big-bore diesel engines from International and several other engine manufacturers. Introduced in 1973, the Paystar F-5050 6x6 model replaced the M6123-50. It was designed for straight truck construction applications needing the traction of all-wheel-drive but not requiring the power of big-bore diesel engines.

Engine options / changes

In 1975 the 200-hp International DV550B V8 diesel engine was replaced by the redesigned 190-hp D190 and International added the new 210-hp DT466 turbocharged inline six. The Cummins V555 was downrated to 216 hp. The 225-hp Caterpillar 1160 was replaced by the redesigned 210-hp 3208. The 225-hp Cummins VT555 and 210-hp Detroit Diesel 6V53N continued without change. By 1985 only International engines were available, the DT466 outside of California and the intercooled DTI-466 in California, both rated at 210 hp.

The F5050 6x6 replaced the M6123-50 and used the same engines as the F5050 6x4.
