General description

Warning! Turbochargers operate at high speeds and at high temperatures. Keep fingers, tools and debris
away from the inlet and outlet ports of the turbocharger. Do not touch hot surfaces.
The Schwitzer S1B turbocharger (A), is fitted between the exhaust and the induction manifolds and is driven
by exhaust gases. Air is supplied to the engine at more than atmospheric pressure. The turbocharger is
lubricated by oil from the filter head. The oil passes through the bearing housing of the turbocharger and
returns to the lubricating oil sump.
Some engines have the turbochargers mounted towards the front of the engine or centrally according to the
application it is fitted to.
Always use the manufacturer's instructions and specialist assistance to fit the service kit for the turbocharger.
Caution: Do not use a caustic solution to clean the components of the turbocharger because the turbocharger
will be damaged.
