KS-801009 Automotive A/C Compressor Clutch Component Set

KS-801009 is a replacement set for an automotive A/C compressor clutch assembly, designed to address a common failure point in vehicle air conditioning: the compressor no longer engaging reliably, slipping under load, or making noise at the front of the compressor. For workshops and distributors handling AC Parts and Air Conditioning Parts, this kind of component kit helps restore cooling performance without replacing the entire compressor when the rest of the system is still serviceable.

The visible set includes three main pieces: a perforated drive plate or hub, a clutch coil or armature-style component with a threaded central section, and a grooved pulley with a sealed bearing. Together, these Air Conditioner Components connect the belt drive to the compressor when the clutch is energized, then release it when cooling demand drops.

Product Overview

This product belongs in the repair category for compressor clutch service. In many vehicle systems, the clutch is the interface between the engine accessory belt and the compressor shaft. When wear builds up on the contact face, the bearing becomes rough, or the coil loses consistency, the system may still have refrigerant and power but the compressor will not cycle correctly. That can lead to weak cabin cooling, intermittent operation, belt noise, or complete loss of engagement.

KS-801009 appears suited for maintenance, refurbishment, and clutch replacement on compatible compressors. Because exact vehicle fitment is not supplied, buyers should verify compressor model, mounting style, and dimensional match before ordering. For a sourcing team building a catalog of Cooling System Parts, this is the kind of item that supports repair efficiency and reduces unnecessary compressor replacement.

Visible Specifications and Structural Features

Three-piece assembly

The photographed set shows a multi-part clutch arrangement rather than a single loose component. One part is a round plate with evenly spaced holes around the outer ring and a raised center boss. Another part has a threaded center hub and protruding mounting lugs. The third is a pulley with multiple belt grooves and a visible bearing seal.

Functional geometry

The perforated plate design suggests weight management and mounting flexibility, while the grooved pulley is built to run with a serpentine or multi-rib belt. The sealed bearing visible in the pulley center is an important service point because bearing wear often creates noise before total failure. The threaded hub on the middle component indicates a mechanical attachment or alignment feature, which is common in compressor clutch assemblies.

Surface and appearance

Most surfaces appear black-coated, painted, or phosphated, with some machined silver metal visible on the hub and threaded section. That finish may help with corrosion resistance and handling durability, although the exact coating type is not confirmed. The parts show a practical, production-oriented appearance typical of Air Conditioning Accessories intended for service replacement.

Materials and Finish Options

Based on the visible details, the set appears to combine stamped steel, machined metal, and a bearing assembly. The outer plates are likely formed metal parts, while the pulley body is machined to carry the belt grooves and house the bearing. The center elements may include steel or aluminum, but the exact grades are not provided.

For buyers comparing Air Conditioner Components, finish choice matters because compressor clutch parts work in a hot, vibrating, contamination-prone location near the engine. Common industry options include painted, coated, phosphated, or otherwise treated surfaces to improve corrosion resistance and handling stability. If a customer needs a specific appearance or surface treatment for inventory consistency, that should be confirmed at the quotation stage.

Manufacturing and Assembly Approach

The visible shapes suggest a manufacturing process that may include precision stamping, machining, pressing, and final assembly. The plate components look suitable for stamped production, while the pulley and hub likely require turned or machined features. The bearing appears pressed into the pulley body, which is a standard approach for reducing play and supporting belt rotation.

In practice, compressor clutch parts depend on accurate concentricity, stable fit, and clean mating surfaces. Even without published tolerances, buyers should expect careful alignment between the pulley bearing, center hub, and clutch face. That is especially important for distributors stocking AC Parts for repair shops that need predictable installation behavior.

Application Scenarios

This type of part is used in vehicle air-conditioning repair, compressor clutch refurbishment, and maintenance work where the compressor itself may still be structurally acceptable. Auto repair shops often need these components when a customer reports no cooling, noisy operation, or a clutch that will not pull in. For parts wholesalers, it can serve as a practical replacement item in a broader line of Cooling System Parts.

It is worth distinguishing this item from unrelated climate-control items such as an AC Capacitor or an AC Evaporator. Those parts belong to different systems or assembly positions. KS-801009 is focused on the compressor clutch side of the vehicle A/C circuit.

Quality Control Considerations

For this category, quality control usually centers on visual integrity, bearing smoothness, surface finish, thread condition, and assembly fit. Buyers should check that the pulley spins smoothly, the grooves are uniform, and the hub threads are clean. The plate faces should be free from obvious burrs, distortion, or coating damage that could affect engagement.

Because exact test data is not supplied here, a smart purchasing review should include sample inspection, dimensional verification, and comparison with the removed original part. This is especially important for Air Conditioning Parts used in service environments where a small mismatch can create noise or premature wear.

Customization and Buying Guidance

When sourcing KS-801009, the key decision factors are compressor compatibility, pulley groove profile, hub style, bearing condition, and the exact clutch architecture required by the vehicle application. Since the fitment details are not listed, buyers should confirm the compressor brand, shaft interface, and mounting pattern before placing bulk orders.

If you need packaging, labeling, or catalog integration support for Air Conditioning Accessories, those details can often be discussed at inquiry stage. Customization may also include kit configuration, but any exact option should be confirmed directly with the supplier rather than assumed.

Request a Quote or Fitment Check

If you are sourcing KS-801009 for workshop use, wholesale supply, or compressor repair inventory, send the sample photo, old part, or compressor reference for verification. A clear fitment check helps avoid return issues and speeds up service work.
