Key Features

• Factory-Specified Synthetic Gear Oil — Mobil SHC 634 ISO VG640 is a high-viscosity synthetic lubricant engineered for the extreme pressure and load conditions found in trowel gearboxes and masonry saw drives.
• Genuine OEM Specification — This is the exact lubricant called out by Multiquip for these machine families, eliminating guesswork when servicing gear cases and drive components.
• Broad Fitment Across Trowel and Saw Families — Covers walk-behind trowels (J, JA, C, CA, B, HDA, PRO series), ride-on trowels (JTN, HTN, JWN, JTO series), and MS20 and MS30 masonry saws.
• Protects Against Gear Wear and Heat Buildup — The ISO VG640 viscosity grade maintains a stable lubricating film under high-load, high-temperature operating conditions, protecting internal gear sets from premature wear.
• Correct Viscosity Prevents Overheating and Seizure — Running the wrong viscosity oil in a trowel gearbox can cause overheating, accelerated wear, or catastrophic gear failure mid-pour — this spec eliminates that risk.

Trowel gearboxes and masonry saw drive housings operate under sustained mechanical load and generate significant heat during normal use. The lubricating oil inside these housings forms a protective film between gear teeth and bearing surfaces, reducing metal-to-metal contact and carrying heat away from critical components. When oil degrades, becomes contaminated, or is replaced with an incorrect viscosity grade, gear wear accelerates rapidly and can lead to housing seizure or complete gearbox failure. Using the Multiquip 20111-001 Oil, Mobil SHC 634 ISO VG640 ensures the correct fluid is always in service, keeping internal components protected through demanding concrete finishing and cutting applications.
