| ZAXIS 120 | TC01377 |
The TC01377 track cylinder zaxis 120 is a critical internal engine component for the ZAXIS 120, providing the sealed combustion environment required for efficient fuel ignition and mechanical power generation. Engine internal component failure leads to reduced compression, increased oil consumption, and heavy exhaust smoke — all signs of deteriorating combustion seal integrity. Built to OEM specification TC01377 for precise fitment on the ZAXIS 120 with correct clearances and compression restored.
Key Features:
- Precise Internal Fitment: Machined to OEM tolerances for correct piston-to-bore clearance and ring seal performance.
- OEM Specification: Built to reference TC01377 for direct fitment on the ZAXIS 120.
- Power Restoration: Restores full engine compression and power output lost through worn internal components.
The TC01377 track cylinder zaxis 120 is a critical internal engine component for restoring compression performance and engine reliability on the ZAXIS 120.
What Does This Track Cylinder / Piston / Rod Nut / Flange Do?
The track adjuster cylinder uses grease or hydraulic pressure to tension the track chain via the front idler, maintaining the correct sag for safe operation. The piston, rod nut, and flanges are the internal and external sealing and retention components of the cylinder assembly.
Possible Track Cylinder / Piston / Rod Nut / Flange Problem Symptoms
If your machine is showing any of the following, a faulty track cylinder / piston / rod nut / flange may be the cause:
- Track sagging excessively and slipping off the sprocket or idler under load
- Track too tight, causing accelerated wear on the undercarriage components
- Grease leaking from the track adjuster cylinder or valve body
- Track tension not holding after adjustment — releasing slowly over a short operating period
