DESCRIPTION

(SC400)

PR02N–04

The propeller shaft is a 2–part type, each part consisting of a strong, compact precisely balanced tube. The
propeller shaft is connected to the transmission and the differential via 3 joints. No.1 and No.3 joints are
made of flexible rubber couplings. No.2 joint is a Hooke’s universal joint. All 3 joints are carefully arranged
in such a way that their shaft angles rest on a straight line. This design ensures a precise drive line linearity
from the engine through the differential to minimize noise and vibration.

A shaft length adjusting mechanism is incorporated in order to make propeller shaft removal and reinstalla-
tion easier.
