Abstract
A piston for actuating a brake-band end of a transmission band system includes a piston for actuating a band in a transmission. The piston includes a piston body, and an elongated guide shaft having a proximal end fixed to one side of the piston body and a distal end defining a first annular support surface. The guide shaft is formed to include an axial bore having an opening in the first annular support surface. The piston further includes a piston rod having an outer end for engaging the transmission band, an inner end for reception in the axial bore, and a second annular support surface situated to confront the first annular support surface when the inner end of the piston rod is received in the axial bore of the elongated guide shaft. An O-ring is positioned along the inner end of the piston rod, to retain the inner end within the axial bore of the elongated shaft. At least one spacer mean is situated intermediate the first and second annular support surfaces to separate the annular support surfaces to vary the effective length of the piston rod.
