8.2.1.1 Drive Belt/Cover/Pulleys
The drive belt and the associated pulleys will, over time, become worn or damaged, or
may simply be out of alignment. It is essential that the drive belt and the pulleys are in
excellent condition for proper operation of the Compressor Condenser Module
assembly. If the drive belt edges are showing signs of wearing or if cracking is
noticed, it should be replaced. If the motor drive pulley is showing signs of wearing,
both on the pulley teeth and pulley flanges, it should be replaced. If belt cover is
cracked or damaged in any way, it should be replaced. If assembly is out of
alignment, system will need to be aligned and tensioned. Refer to Disassembly
(Section 5) and Assembly (Section 9). Contact Enviro Systems customer service to
order new components.
8.2.1.2 Drive Motor/Brushes
Drive motor brushes can, over time, become worn or damaged. It is essential that the
drive motor brushes remain in excellent condition for proper operation of the
compressor condenser module assembly. They must be replaced according to the
inspection schedule in Section 7. Refer to Disassembly (Section 5) and Assembly
(Section 9). The commutator on the armature must be in serviceable condition to
maintain proper operation. See Section 7 for inspection criteria.
8.2.1.3 Compressor Assembly
The compressor and pulley can, over time, become dirty and shows signs of wear
and/or damage. It is essential that the compressor and its pulley remain in excellent
condition for proper operation of the Compressor Condenser Module assembly.
Check the pulley condition as per 8.2.1.1. If there is damage to the pulley, it should
be replaced. Check the compressor shaft seal as per .2.1.4. If a leak is detected and
it is excessive, the compressor should be replaced. If there is visible damage to the
compressor housing, the compressor should be replaced. Refer to Disassembly
(Section 5) and Assembly (Section 9). Contact Enviro Systems customer service.
8.2.1.4 Compressor Shaft Seal
Over time, the compressor shaft seal may show signs of excessive oil spray and this
can cause the Compressor Condenser Module assembly to have less than optimal
performance. If excessive oil spray is observed, the compressor should be replaced.
Refer to Disassembly (Section 5) and Assembly (Section 9). Contact Enviro Systems
customer service to order new compressor.
NOTE: If the compressor has not been operated for 30-60 days or more, the dynamic shaft seal may indicate
a small leak due to the absence of oil on the dynamic seal surface. Operation of the system should eliminate
this type of leak. If not, proceed with removal and replacement procedures.
