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

Model history[edit | edit source]

Introduced in 1973, the Paystar F-5050 6x6 replaced the M6123-50. It was designed for straight truck construction applications not requiring the power of big-bore diesel engines. It was a 6x4 model with mid-range diesel engines. It replaced the M623-50.[Entry need details checking]

Engine options / changes[edit | edit source]

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.
