How to Attach a Pulley to a Motor Shaft? (4 Easy Steps)

Mechanical work is not often pleasant. Knowing how tiring the work may be, many might not even attempt it. Moreover, attaching a pulley can be lengthy. It happens if you do not know the correct way to install it. 

But don’t worry, today we’ve come with the intention to help you out! How to attach a pulley to the motor? 

The process of attaching a pulley is fairly easy. First, make a decision on where to hang the pulley. Then choose the proper hook to hang the pulley on. Apply screw to the pulley into the rafter. Lastly, mount and set the pulley. If you follow this chronologically, you can attach it.

But that was the gist of the whole procedure. You need to be clear about the process to attach the pulley.  Go through our article for the details!.

How to Attach a Pulley to a Motor Shaft?

Attaching a pulley to a motor shaft may sound complicated but it can be done quite easily. Especially if you follow our guide. 

We have prepared a 4 stepwise procedure for your convenience. 

Tools Required

Before we jump straight into the process, make sure you’ve got everything you need. Here are some tools you need for this process-

  • Gloves
  • Hammers
  • Nails
  • Gauge
  • Gear Puller
  • Washer
  • Shovel
  • Post Hole Digger
  • Wire Cutter
  • Crimping Tool
  • Post Pounder
  • Fence Pliers
  • Goggles e

Got all the tools along with you? Now let’s get started with our handyman task! 

Step 1 of 4: Fitting the Gauge

The first step is to choose a place to hang your pulley. A go/no-go gauge will be installed when the motor is manufactured.

This is made to the shaft extension’s smallest dimension. It’s also used to make sure the shaft is in the right place inside the motor housing. 

Take a look at our suggestions on the right gauge for you-

This gauge is placed over the shaft and checked to ensure that it is correctly fitted. Before hanging though, you must be aware of the drywall nails or screws. 

This gauge is utilized once again when a motor is returned from the field. If the shaft has been “knocked back,” this examination will reveal it very fast.

Step 2 of 4: Installing the Pulleys

When utilizing the following directions, the component hub should be drawn against the shaft reference step. This should be in line with the motor reference face.

There is a method that pushes the pulley down the shaft. This is done while pushing the shaft up through the pulley. It should be used when installing a pulley. 

Using a bolt and a washer is a basic method. Unscrew the bolt once it has bottomed out and replace it with a new washer. Carry on in this manner until the pulley is firmly in place. 

Never smash or force the pulley onto the shaft because this will damage the bearing. This may also damage the encoder, limiting the motor’s lifespan.

Step 3 of 4: Eliminate Pulleys from Rotors

After a study into shaft snapping revealed that the groves required to accommodate the Circlips damaged the shaft, we eliminated them from our rotors. Now you might want to know the uses of Circlips too.

A two- or three-legged gear puller is required to remove pulleys. Screw the pulley to mount it onto the Shaft.

Here are our recommendations on quality gear pullers if you need one. You can purchase yours from here-

These are just the things you need. You’ll not be disappointed with their performance.

Step 4 of 4: Mount the Pulley

A two or three-legged gear puller is required to remove pulleys. This tool grabs the pulley’s outer trim. It allows the pulley to be raised off the shaft without applying any force to the motor.

It is done by using the gear puller’s threaded screw against the shaft.

To protect the thread, a socket head screw should be inserted into the end of the shaft. If these easy measures are not followed, the motor may become inoperable or require repair. 

We’ve also listed our top socket heads, as you may not have them around. Check out our recommendations below-

These are pretty strong and will be helpful for your work.

With that being said, your work is done. You’ve successfully attached your pulley to the motor shaft. We hope this guide was helpful for you!

Frequently Asked Questions

Question: How do you attach a pulley to a shaft?

Answer: A mechanic tightens mounting screws to secure a pulley, drawing the tapered surfaces of the bushing and pulley hub together. The wedging action between the bushing and the pulley, as well as the bushing and the drive shaft, is created by forcing the mating tapers together.

Question: What is a shaft pulley?

Answer: A pulley is a wheel on an axle or shaft that supports movement and direction changing of a taut cable or belt, as well as power transfer between the shaft and the cable or belt.

Question: How do you mount a shaft?

Answer: Count on press-fit bearings to keep things in place. Outside the bearing, use a shaft collar with a set screw. A pin should be inserted into a bored hole in the shaft. Use a lock nut to thread the shaft’s ends.
