The Multiquip 52138 Left Side Engine Cover is a genuine OEM component designed for HTX6H and STX6H ride-on power trowels and WBH series power buggies. As a direct Multiquip OEM replacement, this cover is manufactured to the same specifications as the original part, ensuring a correct, hassle-free installation with no fitment guesswork. Verified compatible models include the HTX6H, STX6H, WBH21EPA, WBH-21EFP, and WBH-21EF — making part number 52138 the right call when you need a confirmed fit across this equipment lineup.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional standards, ensuring the cover mounts flush and seals correctly against the engine housing without gaps or misalignment.
- Direct Drop-In Replacement — Engineered to match the original mounting points and hardware positions on the HTX6H, STX6H, WBH21EPA, WBH-21EFP, and WBH-21EF, so installation follows the same process as the factory-fitted part.
- Broad Model Coverage — A single part number covers both hydrostatic ride-on trowel models and multiple WBH power buggy variants, simplifying parts sourcing across your fleet.
- Engine Protection — A properly fitted engine cover shields internal components from debris, water ingress, and mechanical damage during operation, helping maintain consistent engine performance across demanding job cycles.
- Structural Integrity — A damaged or missing engine cover exposes fuel, electrical, and cooling components to impact and contamination; replacing with an OEM-spec panel restores the protection the machine was built with.
The left side engine cover serves as a protective enclosure panel on the engine assembly, shielding critical components — including fuel system hardware, wiring, and cooling structures — from debris, moisture, and physical contact during operation. On ride-on trowels and power buggies, this cover also contributes to proper airflow management around the engine compartment, which affects thermal performance during extended run times. A cracked, missing, or poorly fitting cover leaves these systems exposed, increasing the risk of contamination-related failures and accelerating wear on components that rely on clean, controlled operating conditions.
