The Multiquip 22888 Engine ECU Mount is a genuine OEM component designed for STXD6i and HTXD6i hydrostatic ride-on power trowels. As a direct Multiquip OEM replacement, this mount is manufactured to the same specification as the original part it replaces, ensuring a correct, secure fit within the machine's engine control system. If your existing mount is cracked, damaged, or showing wear, the 22888 is the exact replacement to restore proper ECU positioning and protect the control unit during operation.

Key Features
- Genuine OEM Construction — Manufactured by Multiquip to the original design spec, meaning the mounting geometry, hardware interface, and material grade match what came off the production line.
- Direct Bolt-In Replacement — Part number 22888 installs directly into the ECU mounting location on compatible trowels with no modification to surrounding brackets or hardware.
- Confirmed Fitment for STXD6i and HTXD6i — Verified for Whiteman hydrostatic ride-on power trowel models STXD6i and HTXD6i.
- Protects the Engine Control Unit — A properly seated ECU mount holds the control module securely against vibration, preventing connector stress, signal faults, and premature ECU failure during heavy troweling work.
- Electrical System Integrity — Correct mounting reduces the risk of vibration-induced wiring harness damage, helping maintain consistent engine management performance across the trowel's operating cycle.
The engine ECU mount secures the electronic control unit to the machine's frame, isolating it from the significant vibration generated during concrete finishing operations. Without a solid, intact mount, the ECU can shift position or be exposed to repeated impact stress, which can loosen connectors, damage circuit boards, or trigger erratic engine behavior. Replacing a worn or broken mount promptly is a straightforward way to protect a component that is far more expensive to replace than the bracket holding it in place.
