Multiquip 1406 Clutch End Plug

The Multiquip 1406 Clutch End Plug is a genuine OEM component designed for J36, JA, B46S90, CA4HC, JS36, and related walk-behind power trowel series. This small but critical plug seals the clutch assembly on a wide range of Multiquip and Whiteman walk-behind trowels, ensuring the clutch housing stays protected during operation. Verified fitment spans the J Series, C and CA Series, Heavy Duty HDA Series, and several international variants — making the 1406 one of the most broadly compatible clutch components in the walk-behind trowel lineup.

Key Features

• Genuine OEM Sealing Integrity — Sourced directly from Multiquip, this end plug meets the original material and dimensional spec for a secure, leak-free seal within the clutch housing.
• Drop-In Clutch Housing Fit — Engineered to seat precisely into the clutch bore with no rework, matching the original installation method on all listed trowel models.
• Broad Walk-Behind Trowel Coverage — Compatible with J36, JS36, J36S60, B46S90, CA4HC, CA5BC, CS24H55E, HPHA36C5H, J3036H55, JS36H55, JS36H90, and additional J Series and Epoxy Series configurations.
• Protects Clutch Assembly from Contamination — Keeps debris, concrete dust, and moisture out of the clutch bore, preserving clutch engagement and extending service life of surrounding components.
• Part of Routine Clutch Service — Replacing a worn or damaged end plug during clutch maintenance restores the sealed condition of the assembly and prevents premature wear on internal clutch parts.

The clutch end plug closes off the open end of the clutch housing on a walk-behind power trowel, creating a sealed environment that protects internal clutch components from contaminants common on concrete finishing jobsites. When the plug is cracked, missing, or improperly seated, dust and moisture can enter the clutch bore, accelerating wear on the clutch mechanism and leading to inconsistent engagement or slippage. Replacing the 1406 as part of regular clutch service keeps the assembly sealed and functioning as intended.
