How To Remove PTO Shaft Lock Pin? 6 Step Solution

Most often, if you need to repair or replace a component on your agricultural equipment, you’ll be required to remove the PTO (power take-off) shaft lock pin. It locks the two halves of the joint together and can be found on the yoke or universal joint of the shaft. 

But how to remove the PTO shaft lock pin? Removing the lock pin is a relatively simple process. First, locate the pin on the joint and then use pliers to bend the locking tabs away from the yoke. Finally, use a pin removal tool to pull it straight out of the shaft. You may need to take extra measures if the pin is stuck or difficult to remove. 

This guide will provide a general procedure for removing a PTO shaft lock pin and what to do in case it gets stuck. Read on to learn the process precisely. 

How to Remove PTO Shaft Lock Pin

The process for removing a PTO (power take-off) shaft lock pin may vary slightly depending on the specific type of PTO shaft you are working with. But here is a general procedure that you can follow step by step. 

Step 1: Identify the lock pin

The PTO shaft lock pin is usually located on the yoke or universal joint of the shaft. This is a small metal pin that locks the two halves of the joint together.

Step 2: Position the shaft

Ensure the PTO shaft is securely positioned and cannot move during the removal. Use a vise or other clamping mechanism to hold it in place.

Step 3: Remove the retaining clip 

Some PTO shafts have a retaining clip holding the lock pin. Use a pair of pliers to remove the clip and set it aside.

Step 4: Remove the lock pin

Carefully remove the lock pin from the yoke or joint using a pair of pliers or a small pry bar. Hold the pin, so it doesn’t fall into the machinery or get lost.

Step 5: Separate the joint

Once the lock pin is removed, you should be able to separate the two halves of the joint by pulling or twisting them apart. If they are stuck, use a bit of lubricant or a gentle tapping with a rubber mallet to loosen them.

Step 6: Replace the lock pin

When you’re ready to reassemble the PTO shaft, simply insert the lock pin back into the yoke or joint, ensuring it’s fully seated and secure. Then replace the retaining clip if applicable.

Even though the procedure is simple, refer to the manufacturer’s instructions or seek assistance from a qualified mechanic if you are unsure about removing a PTO shaft lock pin. This is a critical safety component in some equipment.

Why Does A Pto Shaft Lock Pin Become Jammed?

A PTO shaft lock pin can become jammed or stuck due to several reasons, including:

1. Rust and Corrosion

If the PTO shaft is exposed to moisture or other corrosive substances, it develops rust or corrosion that causes the components to stick or seize up.

2. Lack of Lubrication

The PTO shaft needs to be properly lubricated to prevent the components from rubbing together and creating friction that can cause the shaft to become stuck.

3. Improper Storage

If the PTO shaft is not stored correctly, it can become damaged or misaligned, which causes the components to become locked.

4. Misuse

When the PTO shaft is used for roughly other than its intended use or is subjected to excessive pressure, it gets jammed or damaged.

5. Wear and Tear

Over time, the components of the PTO shaft can become worn or damaged, causing the shaft to become locked or fail to function correctly.

Therefore, to prevent a PTO shaft from becoming locked, it’s essential to maintain and lubricate it properly. Then store it in a dry and protected area, and use it only for its intended purpose. Regular inspections and maintenance can also help identify and address any issues before they become more serious.

What’s The Cost Of Replacing a PTO Shaft?

In general, the cost of a new PTO shaft may range from $200 to $600 or more, depending on the make and model of the equipment. If you opt for a used PTO shaft, the cost could be lower, but there may be a risk of reduced reliability or limited availability.

The cost of labor to replace a PTO shaft can also vary widely depending on the provider. The average hourly rate for labor costs is around $30 to $50, depending on the job’s specifics.

Final Words

With the correct tools and techniques, removing a PTO (power take-off) shaft lock pin is an uncomplicated task that can save time and money if done correctly. 

Although the process may seem daunting, you can easily remove a jammed PTO shaft lock pin by following the steps outlined in this guide. If you are still confused and lack confidence, call a mechanic. A professional technician can help you remove the PTO shaft locking pin quickly.
