Check that the flange surfaces on the
transmission housing and gearbox are clean.
When fitting the transmission shaft, the arrow on
the shaft must point forward.
On the rear of the transmission shaft is a white
marking indicating the point of maximum
imbalance. This marking must be kept
approximately 180° from the one or two
conical recesses on the gearbox flange (point
of max. gearbox imbalance) and from the
marking made on the transmission housing
(point of max. flywheel imbalance), as shown
in the previous photo.
If there are two machined conical recesses on
the gearbox flange, use the centre point
between the two recesses as a reference
point.
If there are no conical machined recesses, the
gearbox is perfectly balanced and no
referencing relative to the transmission shaft
is necessary.
The positions of the markings shown in the
photo aside are indicative only.
Then fit transmission shaft (A) in the relative
seat, inserting from front to back.
