In 1966 an updated version of the Nissan Junior was launched, the 41 series.
The 1966 41 series Junior is actually exactly the same as the previous 40 series Junior in every way, except for the engine. The new 41 model was fitted with the new 2 litre H20 engine, which was just introduced as the base model engine for the new 130 series Nissan Cedric. The new H20 was a 1982cc 4 cylinder OHV engine which produced 99hp at 5000rpm. Initially the H20 had a 3 bearing crankshaft, but halfway through 1967 it was changed to a 5 bearing crankshaft.
At the same time as this change all the engine bolt threads changed from UNF and UNC to metric. The 1488cc G series engine, which was the entry level motor for the 40 series has now been dropped from the range. The only other engine option was the SD22 diesel engine.
The grille on the first of the 41 Juniors is the same as the one used on the previous 1964 40 series, which consists of seven horizontal bars and three vertical bars in a section between the headlight surrounds, and below that is a wide horizontal strip with four horizontal slots cut into it. The grille was chrome plated and it had a red Junior badge mounted to it, and the strip under it was painted the same colour as the body. The front bumper bar is painted white and has a slot for an emergency crank handle above the number plate.
By 1967 the 41 series Junior was looking a bit dated, and an attempt was made to update it's appearance.
The 1967 model 41 has a new grille with 4 equal sized wide horizontal bars. The panel under the grille has also been changed and instead of being a straight horizontal panel the top of it now curves upwards at each end to create a grille and headlight opening that is an elongated oval shape. This new panel now has three large horizontal slots cut out of it instead of the four slots in the previous model. The bumper bar no longer has the slot for the emergency crank handle mounted above the number plate. On this model the bumper, grille and headlight surrounds are all painted silver. Instead of two strips on the bonnet there is now a large shield shaped badge. The instrument binnacle on the previous models was painted a dark grey charcoal sort of colour, from 1967 onwards this panel was painted silver.
In 1968 another update occured. The only change at this time was a new grille, with a very wide horizontal bar top and bottom, and three thin horizontal bars in between. Everything else remained unchanged.
The badges on the side of the vehicle say Nissan Junior, with a 2000 badge underneath.
The 41 series Junior was in production until September 1970, by which time it had been in production for over eight and was now a very outdated vehicle. The 41 was replaced by the 140 series Nissan Junior, which was a much more modern vehicle, though not a popular one. The 140 was initially offered in several export markets, but was not a success, and after that it was sold primarilly in Japan and other Asian markets. The 140 Junior continued on until production ended in 1982. It was not replaced.
The initila launch version from 1966 continued to use the same grille as the previous 40 series Junior.
In 1967 there was a minor cosmetic upgrade to the Junior. The 1967 model 41 has a new grille with 4 equal sized wide horizontal bars. The panel under the grille has also been changed and instead of being a straight horizontal panel the top of it now curves upwards at each end to create a grille and headlight opening that is an elongated oval shape. This new panel now has three large horizontal slots cut out of it instead of the four slots in the previous model.
In 1968 another update occured. The only change at this time was a new grille, with a very wide horizontal bar top and bottom, and three thin horizontal bars in between. Everything else remained unchanged.
The truck version was available with either a "styleside" cargo area as pictured here, or with a steel cargo area with fold down sides, or as a cab/chassis which was called the 41-A.
The 41 series Junior was also available with a diesel engine. The engine used was the Nissan SD22, which was a 2164cc with a Diesel Kiki brand mechanical injection system that produced 70hp.
The Junior 41 could be ordered as the 41-E, also known as the "E Chassis", which gave you only a running chassis with the front section and the windscreen, and nothing else. Another option based on this "E Chassis" was the F40, which was a small fire truck version.
