Title:
SPRING(CLUTCH,SUB) (KU-3S20330480)
Description:
The 3S20330480 clutch sub spring applies controlled tension within the clutch assembly, while also supporting smooth engagement and disengagement of the transmission system. It works alongside other clutch components to maintain proper pressure and alignment during operation.
Kubota manufactures this spring from high-strength steel, so it withstands repeated compression cycles and heavy load conditions. As a result, it ensures consistent clutch performance, reduces slippage, and improves overall drivetrain reliability.
Model Fitment:
Kubota assigns this part within specific clutch assemblies, so fitment depends on transmission type and internal configuration, not just model range.
