3.10. V-belt tension check and adjust
By the finger-pressure the belt is pressed by
10mm ~ 15mm between the fan pulley and
the alternator pulley in normal condition. For
the adjustment of the tension, loosen the
adjusting bolts which support the alternator,
adjust the tension and tighten the bolts
again.
3.11. Turbocharger
The exhaust gases of the engine are passed through the turbine rotor of the turbocharger. Air
compressor impeller mounted on the same shaft draws in fresh air and delivers it at a higher
pressure to the cylinders.
The turbocharger is naturally air-cooled. Lubrication of the main bearing is by oil under
pressure from the engine lubricating system.
