[edit] Modifications
Production of 4YG and 3XJ ended in 1993.
The Caterpillar 966F Series II wheel loader was introduced in 1993 in the USA, Japan, and Belgium. At this time Caterpillar updated the Japanese 8BG unit, beginning with 8BG02048, and began to produce new units in the USA, with a 1SL prefix, and Belgium, with a 9YJ prefix.
With Series II Cat added a number of features, including a larger, more modern operator compartment, lower sound levels, implement efforts, electric shift with autoshift, lower cab height, modified access/egress, and a new marking system.
Later in 1993 Caterpillar added full hydraulic brakes, optional ether starting aid and air suspension seat, moved the operator horn control from the floor to the steering wheel, and replaced CSC-based R12 in the air conditioner with R134A refrigerant, beginning with 1SL00507, 8BG02191, and 9YJ01082.
In 1995 Cat added a modular monitoring system with electronic analog gauges, noise-reduced engine mounts, silicon-bonded windshields, and modified transmission access, beginning with 1SL01344.
Production ended in the USA and Belgium in 1998 and Japan in 1999.
The Caterpillar 966F II was replaced by the Caterpillar 966G.
Based on data from the sales database of Ritchie Bros. Auctioneers, it is estimated that more than 16,300 Caterpillar 966F and 966F Series II wheel loaders have been produced.
