SERVICE - Custom A5 Sealed Compressor/Clutch Recondition

$435 plus s/h. Parts and repairs, if needed, are additional.
SKU: 17-A5S-d
Make: CHEVROLET
Call for availability

Custom reconditioning of your original A5 Sealed compressor and clutch core. Reconditioning consists of initial test to determine the core is serviceable*, following by stripping exterior surfaces to bare metal and dismantling*. Compressor is hot-flushed at 180 degrees until contaminant free, the original shaft seal is removed, rebuild and reinstalled, a full 11oz. oil charge is added and the compressor is pressure tested for leaks with Nitrogen at 250 psi. The clutch bearing, clutch disks, clutch hub and various related pieces are cleaned, inspected, calibrated and reassembled on the compressor**. Complete unit is performance tested at 1,800 rpm's and painted. A new "Caution" decal is installed and the compressor is stamped with the "OK FINAL TEST" stamp. NOTE - Because not all A5 compressors are rebuildable and the determination cannot be made accurately until disassembled, there is a 1-hour labor evaluation charge ($90). This charge is billed in advance and is applied toward the rebuild of your compressor if it is determined to be a good core candidate for rebuild. Compressor cores that are seized cannot be rebuilt. * NOTE 1 - A5 Sealed compressors cannot be opened up and rebuild like most compressors. Instead, this is a reconditioning service of the compressor and a rebuild service of the clutch. ** NOTE 2 - Bearing replacement or clutch hub machining is available at an additional cost.

CONVERTING GENERAL MOTORS CARS

TO 134a

Until 1995, most cars with air conditioning used R-12 Freon refrigerant that is said to have a negative side effect of damaging the ozone layer and is no longer produced in most countries. since then, the industry standard has been R134a, which is an efficient replacement.  Contrary to popular belief, most cars originally equipped with R-12 can be converted to 134a and still keep you just as cool.

 

1955-61 Models with Hot Gas Valve (aka By Pass or Hot Gas By Pass Valve)

The Hot Gas Valve is most often found mounted to the compressor, though some cars have it mounted back near the evaporator. The front half of it looks like a bullet. (Click here for a typical photo)

Minimum Requirements

  • Change or restore the filter-drier.
  • Drain the compressor oil and recharge with 134a compatible oil. (PAG or Ester Oil)
  • Insure that the system is clean and free of contaminants (Depending on component condition, this may be a simple matter of blowing out with compressed air or liquid flushing with an air-conditioning flushing agent)
  • Replace or restore all rubber hoses with barrier hose.
  • Rebuild hot gas valve.
  • Install 134a charge port adapters.
  • Charge with 134a between 70-80% of the original R12 charge amount. Note: Hot gas valve will need to be adjusted during the charging process to properly adjust the low side by-pass pressure to 20psi.
  • Replace any o-rings with 134a compatible.

Recommended:

  • Install hi/lo pressure switch

HELPFUL HINTS

  • Ignore the sight-glass. A properly charged 134a system will likely show bubbles in the sight-glass.
  • Typical 134a charge rate will be approximately 70-80% of the factory R12 charge amount.

 

1962-66 Models with Suction Throttling Valve (aka STV)

The suction throttling valve is installed on the evaporator, near the firewall.(Click here for a typical photo)

Minimum Requirements

  • Change or restore the filter-drier.
  • Drain the compressor oil and recharge with 134a compatible oil. (PAG or Ester Oil)
  • Insure that the system is clean and free of contaminants (Depending on component condition, this may be a simple matter of blowing out with compressed air or liquid flushing with an air-conditioning flushing agent)
  • Replace or restore all rubber hoses with barrier hose.
  • Rebuild suction throttling valve.
  • Install 134a charge port adapters.
  • Charge with 134a between 70-80% of the original R12 charge amount. Note: Suction throttling valve will need to be adjusted during the charging process to properly adjust the low side by-pass pressure to 20psi.
  • Replace any o-rings with 134a compatible.

Recommended:

  • Install hi/lo pressure switch

HELPFUL HINTS

  • Ignore the sight-glass. A properly charged 134a system will likely show bubbles in the sight-glass.
  • Typical 134a charge rate will be approximately 70-80% of the factory R12 charge amount.

 

1966-73 Models with POA Valve

The POA Valve is installed on the evaporator, near the firewall. (Click here for a typical photo)

Minimum Requirements

  • Change or restore the filter-drier.
  • Drain the compressor oil and recharge with 134a compatible oil. (PAG or Ester Oil)
  • Insure that the system is clean and free of contaminants (Depending on component condition, this may be a simple matter of blowing out with compressed air or liquid flushing with an air-conditioning flushing agent)
  • Replace or restore all rubber hoses with barrier hose.
  • Install 134a charge port adapters.
  • Have POA valve recalibrated/rebuilt for 134a, or replaced with a POA Delete Kit
  • Charge with 134a between 70-80% of the original R12 charge amount.
  • Replace any o-rings with 134a compatible.

Recommended:

  • Install hi/lo pressure switch

  • Replace or restore all rubber hoses with barrier hose.
  • Install 134a charge port adapters.
