Can you replace AC compressor pulley?

Can you replace AC compressor pulley?

If the AC compressor on your classic car has stopped working and you would rather not replace it, installing an AC compressor bypass pulley is a viable option for safely and efficiently removing your factory AC compressor.

What size pulley do I need for my air compressor?

The Math of Pulley Sizing There are complicated formulas for determining pulley ratios but in generic, layman terms, simply divide the driven component (pump) by RPM, the driver component (motor or engine) rated by RPM to get the required ratio.

What is a AC pulley?

The AC pulley, or air conditioning pulley, is located on the front of the air conditioning compressor and drives the compressor with help from the engine’s accessory drive system. A failed electronic clutch on a vehicle’s AC compressor can lead to the freeze up of the AC pulley which, in turn, destroys the belt.

What is a compressor bypass pulley?

An AC bypass pulley is a free spinning pulley used to replace the AC compressor on an automotive engine. When the AC compressor goes bad in a vehicle, a consumer often will choose to install an AC bypass pulley. Once installed the vehicle will no longer have air conditioning.

Does a smaller pulley spin faster?

Pulleys of Different or Same Size If a smaller pulley turns a larger one, the larger one will turn slower, but with more power available at the shaft. If a bigger pulley turns a smaller one, the smaller one will turn much faster than the bigger one but with less power available at the shaft.

Does AC pulley always spin?

At all times, the compressor pulley should spin. The magnetic clutch mechanism allows the compressor to pressurize the freon when it engauges. …

What does AC idler pulley do?

The main purpose of the idler pulley is to create tension and guide the drive belt within the engine. Such belts wrap around engine parts including the alternator, the pump for power steering, and the water pump.

Can I use a shorter belt to bypass AC compressor?

The compressor cannot be bypassed without the use of a compressor bypass pulley. Install a new pulley or pulley bearing if it can come off of the compressor and then put on a new belt.

An A/C compressor bypass pulley is a quick fix to quiet a car or truck’s noisy A/C compressor. A bad air conditioner compressor can make a lot of noise. On older models there was a separate belt driving the A/C compressor. When the system went bad, you could simply take off the belt and quiet the compressor.

Does the pulley on the AC compressor turn freely?

Your AC compressor should spin freely without the AC clutch engaged, for example with the defrost and A/C switches turned off. If the pulley does not spin free all the time then your compressor bearing could be wearing out. Click to see full answer.

Should the AC compressor pulley always spin?

Yes the compressor pulley should spin at all times. If it did not then you would have a toasted belt. When the compressor engauges it uses a magnetic clutch mechanism which allows the compressor to pressurize the freon. However during normal AC operation the clutch operates in a continuous on/off/on condition to stabalize the freon pressure.

Can the pulley on the AC compressor be bypassed?

Yes, you can bypass the A/C pulley. You just need to buy a new (shorter) Serpentine belt and run it from harmonic balance/crank pulley to alternator. AFAIK, you don’t even need to take the A/C compressor or pulley off.; seems like there’s enough space.
