Detailed Specifications
B/2B/3B diesels
Japanese market 2B diesel engines pictured here
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.
Available in Japan from 1974 to 1980 (model years) in the BJ40
and BJ43, the B engine was available in Canada from 1978 to
1980 in the BJ40.

2B
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.
