toyota 3f-e

The Toyota F series engine was a series of OHV inline-6-cylinder engines produced by Toyota between November 1949 and 1992. They are known for their high amount of torque at low engine speeds, massive cast-iron blocks and heads and also their high reliability. The F engine had one of the longest production runs of any Toyota engine. The F engines all incorporate overhead valves actuated by pushrods from a gear driven camshaft in the lower portion of the engine.
The engine was developed beginning in December 1948 and was largely a bored out version of the earlier Type B engine. However, Toyota incorporated lessons learned during the war, and the F engine benefitted from lightweight alloy pistons and better lubrication than earlier models. The engine's first installation was in a 1949 version of the Toyota BM truck , originally only in units bound for the Brazilian market. The FM became available in the Japanese market as well beginning in 1950. The F engine gained fame as the Land Cruiser engine, it was used in a variety of other large truck applications as well, such as in fire trucks and the Toyota FQ15 trucks. It was also used in the FH26 police patrol car , FS20-FS50 police patrol cars , the FHJ and FH24 fire trucks and the FS35 and FS45V ambulance....
