GBA20 input unit with mechanical reverse shuttle
A . General
The GBA20 input unit with mechanical reverse shuttle
(Fig. 1) consists of an interchangeable module.
It is located at the front of the main unit.
It is made of two separate parts: the mechanical
reverse shuttle and the Speedshift (see chapter 5).
The input unit receives drive from the engine clutch
and transmits it to the transmission via a driving pinion
(forward operation) or a transfer pinion (reverse opera-
tion).
These pinions are located in the rear compartment of
the input unit.
