Stroke Setting
The Pull Stroke Setter is used to advance the Head Piston
64
to full stroke. The external threads on the Pull Stroke Setter wind into the Head
63
,
pushing the Head Piston back. With the Head Piston fully forward, only one side of the Pull Stroke Setter will wind into the Head, as the Head
Piston prevents thread engagement when using the other side. When the Pull Stroke Setter is wound up to a stop in the Head, the Head Piston
has been advanced to half of the available stroke. The Pull Stroke Setter is then unscrewed and the other side is wound into the Head, completing
the stroke.
The Return Stroke Setter is used to draw the Head Piston
64
fully forward. The Return Stroke Setter stops against the Head
63
, whilst the internal
threads wind on to the Head Piston, drawing it forward. With the Head Piston at full stroke, only one side of the Return Stroke Setter will wind on
to the Head Piston, as the Head prevents thread engagement when using the other side. When the Return Stroke Setter is wound up to a stop in
the Head, the Head Piston has been returned to approximately half of the available stroke. The Return Stroke Setter is then unscrewed and the
other side is wound on to the Head Piston, returning it to the fully forward position.
When either Setter is used, the Head Piston should not rotate. If necessary, a 10mm A/F Allen key should be fitted to the rear of the Head Piston to
prevent rotation. It may be necessary to move the Head Piston forward with the Starter Nut to allow the Return Stroke Setter to engage the
thread.
