The power transmission is achieved by two universal joints DIN 808 (Type EG) a spline shaft and a sliding sleeve. It is important to check the accuracy when connecting the spline shaft to the sliding sleeve. The markings → have to be opposite to each other. Any kind of misconnection leads to an inhomogeneous output and to a quick abrasion. see also...
