How To Find The Correct Replacement Air Conditioning Clutch For Your Truck



Truck Air Conditioning Clutches

Truck Air Conditioning Clutches can be identified by measurements, style and cross reference of original part number and number stamped on the unit. This page was created as a guide to assist you in finding the correct one for your truck.

Basic Clutch Information

The clutch used on a particular truck depends on the type of compressor selected from an option list when the truck was first assembled. However, after miles of service, original parts most likely have been replaced. For whatever reason, a truck originally equipped with a reciprocating compressor may now be using a rotary type or possibly a single groove clutch has been replaced with a double groove. To assure you get the right part the first time, it is important to identify the compressor the clutch is to be used on, and the characterisitics or specifications of the clutch. If possible, check for label or stamped numbers on the clutch body or the coil assembly to identify the clutch. If the clutch marking or label is iliegible the following information will be needed.

We have listed the most popular clutch types used on North American trucks below with instructions on how to measure each style. Measuring your clutch according to these steps will help us find the correct replacement clutch and get you cooling again.

Many other clutch styles exist and all cannot be covered here. Our Customer Services staff has many years of experience and can assist you with additional information.

    Often the number on the old part will help. If the old part number cannot be read use this procedure to measure:
  1. 12 OR 24 VOLT (Black Wire = 12V, Green Wire = 24V)
  2. DETERMINE IF CLUTCH IS SINGLE, DOUBLE OR POLY GROOVE.
  3. MEASURE OUTSIDE DIAMETER OF PULLEY.
  4. MEASURE WIDTH OF PULLEY GROOVE:
    Single and Double Groove = measure the width of pulley groove.
    Poly Groove = count the number of grooves.
  5. MEASURE ACCURATELY THE A-B DISTANCE (see diagram):
    Single and Double Groove = measure the distance from the compressor mounting hole on the side of the compressor to the middle of the rear belt groove on the pulley (the rear belt groove is closest to the compressor).
    Poly Groove = measure the distance from the compressor mounting hole on the side of the compressor to the middle of the first groove on the pulley.
  6. DETERMINE THE NUMBER OF WIRES.
