How to Replace the Motor Assembly in Your Orbit Traveling Sprinkler: A Step-by-Step Guide

A traveling sprinkler, often called a lawn tractor sprinkler, is a convenient way to water large areas automatically. It moves slowly across your yard, pulling a hose behind it, delivering even coverage without you having to move the sprinkler manually. Over time, the motor assembly that drives the wheels can wear out due to grit, moisture, or regular use. When that happens, your sprinkler may stop moving, move erratically, or make unusual noises.

The good news is that replacing the motor assembly is a manageable DIY project. This guide walks you through the signs of a failing motor, the tools you'll need, and the step-by-step process to swap in a new motor assembly. With a little patience and the right approach, you can have your Orbit traveling sprinkler back in action and ready to water your lawn.

Signs Your Traveling Sprinkler Motor Needs Replacement

Before you start taking your sprinkler apart, it helps to confirm that the motor is indeed the culprit. Common symptoms of a failing motor in an Orbit 26025 or similar traveling sprinkler include the unit moving very slowly or not moving at all, even though water flow is normal. You might also hear a grinding or clicking sound from the wheel housing, or the sprinkler may move only in one direction or skip intermittently.

If you have already cleaned the drive gears and checked for obstructions but the problem persists, the motor assembly likely needs replacement. Ignoring a struggling motor can lead to further damage to the gear train, so it's best to address it promptly.

• Sprinkler moves sluggishly or stops mid-run
• Grinding, clicking, or whining noise from the wheel area
• One wheel moves while the other is stuck
• Motor runs but sprinkler does not advance

Tools and Replacement Parts You’ll Need

To replace the motor assembly, you will need a few basic tools: a Phillips-head screwdriver, a flathead screwdriver, a set of pliers, and a small adjustable wrench. A workbench or clean flat surface will make the job easier. The specific motor assembly for your model should be ordered from Orbit or an authorized dealer — the Orbit 26025 traveling sprinkler uses a dedicated replacement motor.

While you are servicing the sprinkler, it's a good opportunity to inspect other parts. If the hose connection is worn, consider using a 5/8" - 3/4" Soft-Touch Female Mender 56121 to repair the hose end. For adjusting sprinkler height or replacing risers, the 1/2" x 18" Multi-Flex Sprinkler Riser 37321 can be a handy addition to your repair kit.

Step 1: Disconnect Water and Power

Safety first. Turn off the water supply at the faucet and disconnect the sprinkler from the hose. If your traveling sprinkler has a battery-powered timer or controller (like some B-hyve models), remove the batteries to prevent any accidental activation. Place the sprinkler on a flat, dry surface where you have good lighting and room to work.

Step 2: Remove the Traveling Sprinkler Housing

The motor assembly is housed inside the body of the sprinkler, under a plastic cover. Use a Phillips-head screwdriver to remove the screws securing the top cover. Depending on the model, there may be four to six screws. Keep them in a safe place. Gently lift off the cover to expose the internal components, including the motor, gearbox, and drive wheels.

Step 3: Detach the Old Motor Assembly

Locate the motor assembly — it is usually a small black or gray unit connected to the gear train by a drive shaft or coupling. Carefully unclip or unscrew the wire harness that powers the motor (if present). Then use a screwdriver or wrench to remove the mounting screws that hold the motor in place. Slide the old motor out, taking note of its orientation so you can install the new one exactly the same way.

Step 4: Install the New Motor Assembly

Position the new motor assembly into the same slot, aligning the drive shaft with the gear train. Secure it with the mounting screws, tightening them just enough to hold firmly — do not overtighten. Reconnect any electrical connectors, making sure the wires are not pinched. If your model uses a mechanical linkage instead of wires, ensure the coupling engages smoothly.

Step 5: Reassemble and Test

Replace the top cover and tighten all screws. Reinstall the batteries if applicable, and reconnect the water hose. Turn on the water supply and set the sprinkler to run on a flat, clear path. Watch for smooth, steady movement. If the sprinkler moves at its normal pace without unusual noises, the replacement was successful. For a final check, run the sprinkler through a full cycle to ensure reliable operation.

Tips for Extending the Life of Your Traveling Sprinkler

Once your sprinkler is back in action, a little preventive maintenance goes a long way. Always use a clean water source and consider installing a filter to keep debris out of the motor area. Store the sprinkler indoors during winter to protect the motor from freezing temperatures. Periodically lubricate the wheel axles with silicone spray to reduce wear.

If your traveling sprinkler is older or you find the repair too complex, upgrading to a different type of sprinkler can be a smart move.
