Baywindow Bus Parts
In late 1967, the second generation of the Volkswagen Type 2 (T2) was introduced. Models before 1971 are often called the T2a (or 'Early Bay'), while models after 1972 are called the T2b (or 'Late Bay').
This second-generation Type 2 lost its distinctive split front windscreen, and was slightly larger and considerably heavier than its predecessor. Its common nicknames are Breadloaf and Bay-window, or Loaf and Bay for short. At 1.6 litres the engine was also slightly larger. The new model also did away with the swing axle rear suspension and transfer boxes previously used to raise ride height. Instead, half-shaft axles fitted with constant velocity joints raised ride height without the wild changes in camber of the Beetle-based swing axle suspension. The updated Bus transaxle is usually sought after by off-road racers using air-cooled Volkswagen components.
The T2b was introduced by way of gradual change over three years. The first models had unique body features, such as curvaceous bumpers with the front bumper wrapping around to form the step when the door was opened (replaced by shapeless stand-off bumpers on later models), front doors that opened right out to 90 degrees from the body, no lip on the front guards, and crescent air intakes in the D-Pillars (later models have squared off intakes). They also had unique engine hatches, and up until 1972 front indicators set low on the nose rather than high on either side of the fresh air grille - thus giving rise to their nickname as 'Low Lights'. The 1971 Type 2 featured a new, 1.6 litre engine with dual intake ports on each cylinder head. An important change came with the introduction of front disc brake and new road wheels with brake ventilation holes and flatter hubcaps. 1972's most prominent change was a bigger engine compartment to fit the larger 1.7 to 2.0 litre engines from the Volkswagen Type 4 and a redesigned rear end which eliminated the removable rear apron. The air inlets were also enlarged to accommodate the increased cooling air needs of the larger engines.
This all-new, larger engine is commonly called the Type 4 engine as opposed to the previous Type 1 engine first introduced in the Type 1 Beetle. This engine was called 'Type 4' because it was originally designed for the Type 4 (411 and 412) automobiles. They used the 'Type 1' engine from the Beetle with minor modifications such as rear mount provisions and different cooling shroud arrangements. The pancake nickname came from its low overall height due to mounting the cooling fan on the end of the crankshaft, a technique later employed for the Type 4 engines. European vans stuck with the upright fan Type 1 1600 engine even after the Type 4 motor became standard for US Type 2 export models.
