The Multiquip 4558 is a genuine OEM Cylinder, 2.5" Bore x 1.5" Str x.75" designed for Multiquip hydrostatic and light-duty ride-on power trowels, including the LD60, LD6, LD6SL, MD105, and MD80 series. As a direct OEM replacement, this cylinder is produced to the same specifications as the original component, ensuring a correct, dependable installation. Sourced directly through authorized Multiquip supply channels, the 4558 is the right part to specify when hydraulic cylinder replacement is needed on these trowel families. DHS Equipment stocks this part to keep your finishing equipment back in service without the guesswork of sourcing an unverified substitute.
Key Features
- OEM-Matched Bore and Stroke Dimensions — Built to exact 2.5" bore, 1.5" stroke, and .75" rod specifications, ensuring correct hydraulic pressure and travel range within the trowel's blade pitch or drive circuit.
- Direct-Fit Installation — Mounts to the same ports and brackets as the original cylinder, eliminating the need to source adapters or modify hydraulic lines during replacement.
- Compatible with LD and MD Series Trowels — Confirmed fitment for LD60, LD6, LD6SL, MD105, and MD80 Whiteman and Multiquip ride-on power trowels.
- Maintains Blade Pitch Control Performance — A properly functioning cylinder delivers consistent, responsive blade angle adjustment; a worn or leaking cylinder causes sluggish or uneven pitch response that directly affects surface finish quality.
- Hydraulic Integrity Under Operating Pressure — Genuine OEM construction ensures seals, bore finish, and rod material are rated to handle the hydraulic pressures these trowel systems generate during continuous finishing operations.
The hydraulic cylinder on a ride-on power trowel is responsible for actuating blade pitch adjustment or drive movement, depending on its location within the machine's hydraulic circuit. It converts hydraulic pressure into controlled linear force, allowing the operator to fine-tune blade angle or manage directional drive response. When a cylinder develops an internal leak, loses sealing integrity, or reaches the end of its service life, the affected circuit loses the ability to hold position under load — resulting in inconsistent blade pitch, drifting machine behavior, or complete loss of that function until the cylinder is replaced.
