New Air Conditioning Accumulators Improve Service Life {7309}

Usage:


Caterpillar Machines With Air Conditioners

Description of Change: New air conditioner accumulators with a longer tube supported by a steel baffle plate provide increased service life and improve reliability.

Adaptable To: The new 152-2823 Air Conditioner Accumulator is a direct replacement for the former 106-1018 Air Conditioner Accumulator. The new 151-5261 Air Conditioner Accumulator is a direct replacement for the former 101-8789 Air Conditioner Accumulator. Refer to the listing below to determine which accumulator is used on specific models.

NOTE: A slow loss of air conditioner performance may be caused by a failing accumulator.
