VESPA 946 E4 EMEA 2021 Manual page 36

Technical Data
- The main bushings have 2 half-bearings, 1 with
and 1 without the lubrication channel.
- The solid half-bearing is intended to stand the
thrusts caused by combustion, and for this reason
it is arranged opposite the cylinder.
- To prevent shutters in the oil feeding channels,
the matching surface of the two half-bearings must
be perfectly orthogonal to the cylinder axis, as
shown in the photo.
