SANY Alternator B221000000090 for SY365 / SR205 / SY285 / SY385 / SY335

Quick Specs

Product Introduction

The B221000000090 alternator is the belt-driven charging unit for SANY SY365, SR205, SY285, SY385 and SY335 machines. It is built from steel, weighs 10.5 kg and measures 110 x 106 x 110 mm, supplied as a complete unit with its multi-groove pulley, mounting brackets and electrical connections.

An alternator generates the electrical power that keeps the battery charged and runs the lights, control units, sensors and cab equipment while the engine is running. When it fails, the usual symptoms are a battery that goes flat overnight, a charge warning lamp on the panel, dim or flickering lights, or a machine that will not restart after being parked. Because a discharged battery and a failed alternator produce very similar symptoms, the charging circuit is normally tested before the unit is renewed, and the alternator is then replaced as a complete assembly. If you are ordering for a repair, check B221000000090 against the number on the alternator you are taking off.
