John Deere X-Series Steering Cylinder Replacement – Now for AM136561 (Later Models)

If you own a John Deere X-Series tractor—including X728, X748, and later machines—you may need a replacement steering cylinder. The latest OEM part number AM136561 is used on newer machines, but availability can be limited and costly. At TekOnline, we’re developing a high-quality aftermarket replacement for this cylinder, designed to be bolt-on, serviceable, and durable, while avoiding the long lead times and high prices of OEM parts.

AM136561 – The Latest John Deere X-Series Steering Cylinder

The AM136561 steering cylinder fits later-model X-Series tractors where older cylinders (AM129510 / AM147178) are no longer compatible. This updated cylinder addresses design changes in:

Mounting geometry
Port location and orientation
Rod diameter and stroke length
Chassis clearance and steering linkage interaction

If your tractor has sloppy steering, leakage, or binding at full lock, it’s likely time to check your cylinder part number—and for later models, AM136561 is what you need.

Evolution of X-Series Steering Cylinders

Understanding the cylinder’s evolution helps explain why TekOnline is focused on AM136561:

AM129510 – Early cylinder used on X575, X585, X595, X728, and X748.
AM147178 – OEM replacement for earlier models, improving fit, rod strength, and reliability.
AM136561 – Current cylinder for later models with revised geometry and mounting points.

TekOnline already offers rebuildable, serviceable solutions for AM129510 and AM147178. Now, we’re developing the next-generation aftermarket replacement for AM136561 to cover the latest X-Series tractors.
