4. Difference Between Right and Left Hand Mounting. All configurations of the turbo discussed in this manual can be

either right or left hand mounted by indexing the turbine housing and compressor cover according to the mounting

location and engine model. Also, the position of the oil drain tube is reversed for right or left hand use. For engine

model AVDS--1790--2DR the turbosupercharger heat shields are removed and discarded before the turbos are

mounted. Part number 655595--3 and 655595--4 turbosuperchargers have different heat shields. Ensure proper

shield is used for left or right bank application.
