Engines

All B series engines are 4 cylinder, 4 cycle diesel engines. Most were manufactured by Hino Industries, a sub-contractor of Toyota. Some were manufactured by Daihatsu, identified by the letter "D" on the timing cover. Apparently Hino engines similar to the B and 3B are used to run the refrigeration units on some tractor-trailers.

Most diesels in Japan and Canada are 24V (and therefore meet NATO military specs), with the exception of Canadian BJ60s and 1985 BJ70s which are 12V. In Europe, all diesels before 1984 are 24V, and most B series after 1984 are 24V as well. Australian diesels are 12V.

3B

The most widely used engine from this series. It apparently came in at least three versions with slightly different stats. One difference is that until 1986, it came with an inline injection pump, and then after 1986 it had a rotary injection pump. In Japan the 3B was used from 1981 to 1990, but Canada stopped importing vehicles with this engine in 1987. The 3B is found in the BJ42, BJ43, BJ45, BJ60, BJ70, BJ73, and BJ75. This engine is a favourite to turbo because like most turbo engines, it has oil nozzles that spray the bottoms of the pistons.
