Description
Overview:
This Worm Gear is a genuine ECHO part for the oil pump drive on compact professional chainsaws, including the CS-2511TES and CS-2510TES. Built from durable, wear-resistant engineered polymer, it transfers rotation from the engine to the oil pump, ensuring consistent bar and chain lubrication during cutting. Correct lubrication protects the guide bar and chain, reduces friction, and supports smooth cutting performance. As an OEM component (V652000230), it offers an accurate fit and reliable operation in demanding use. Suitable for workshop maintenance and field repairs, it helps restore proper oil delivery when the original gear is worn or damaged, maintaining the saw's performance and reducing unnecessary downtime.
Key Features:
- Genuine ECHO OEM worm gear (V652000230) for assured compatibility and quality
- Precision fit restores correct oil pump drive and consistent chain lubrication
- Durable engineered polymer construction resists wear from heat and chain oil
- Worm gear profile provides smooth, quiet, and efficient power transfer
- Helps prevent premature bar and chain wear caused by poor oiling
- Straightforward installation with standard chainsaw service procedures
- Stable performance across typical operating temperatures and conditions
- Reliable choice for routine maintenance or repair after clutch/drive service
- Supports long service life when used with clean bar oil and a maintained pump
- Lightweight, corrosion-proof material minimises added rotating mass
Typical Applications:
Used to replace a worn or stripped oil pump worm gear when a chainsaw shows poor or inconsistent bar oiling, a dry chain, or visible gear tooth damage. Common during routine services, clutch or drum replacements, and after heavy use where lubrication has been compromised. Suitable for professional arborist work, grounds maintenance, and domestic cutting tasks requiring dependable chain lubrication.
