Starter Crank Overhaul Kit: What It’s For and Why It’s Important for Your Lambretta

Anyone who owns a Lambretta knows how important it is to keep every component in perfect working order to ensure reliable performance over time. Among the often overlooked but fundamental elements is the kickstarter, the heart of the starting system. In this article we discover the usefulness of the kickstarter overhaul kit, what problems it solves and when is the right time to install it.
What is the starter crank for?
The crank allows you to manually start the Lambretta engine. Through a decisive movement, the crankshaft receives the necessary push for ignition. When the system is worn, the transmission of movement becomes imprecise, laborious or completely ineffective.
Over the years and with frequent use, internal components can wear out: play increases, the crank action becomes less fluid and vibrations, noises or difficulty in starting may appear.
What does the starter crankset overhaul kit contain?
The starter crank overhaul kit for Lambretta, available on STF Lambretta, includes the essential components to restore the correct functioning of the system:
-
Shaft washer, to reduce friction and adjust the clearance between moving parts
-
Elastic ring, necessary for the correct locking of the elements on the shaft
-
Sealing ring, to prevent dirt or oil infiltration and ensure mechanical seal
All components are made from quality materials and sized to original specifications, to provide a direct replacement without modifications.
When to replace the overhaul kit?
The overhaul kit should be taken into consideration when:
-
the crankset clicks into place or transmits movement irregularly
-
There are abnormal mechanical noises during start-up
