Lepton Lex Replacement Drive Belt

This timing belt is a replacement accessory for the Lepton Lex family, listed under the HIROBO HI2504029 part number. It maintains consistent tooth engagement between pulleys to keep rotor timing and drive operation steady.

Installation notes: inspect pulley teeth for damage and ensure pulleys are aligned, route the belt flat without twists, and apply tension that removes play while not overstressing bearings. Over-tightening will shorten service life and increase friction.

Tuning role: a worn or loose belt can produce slop that affects cyclic response and tail authority on compact helicopters. Fitting the correct 40S2M1166 belt helps restore responsiveness and reduces drivetrain lash. Periodic checks for glazing, fraying, or stretched teeth are recommended.

How long will the HIROBO HI2504029 belt typically last?

Lifespan varies with flying style and maintenance. Under normal use, inspect the reinforced rubber for early signs of wear and replace if teeth show deformation or the belt becomes glazed.

What storage or care extends belt life?

Store belts away from heat and sunlight, avoid contact with oils or solvents, and keep them flat or on a light spool to prevent permanent bends that can affect tooth engagement.

Are there visual signs to watch for during inspections?

Look for frayed edges, missing or rounded teeth, glazing on the tooth faces, or loss of tension after proper adjustment. Any of these indicate replacement is due.
