The Multiquip 13104ZH7000 is a genuine OEM Piston 0.75 Optional designed for CA-4-4H, MC44S, and CA4HM series equipment. As a factory-sourced component, it meets the exact specifications set by Multiquip, ensuring a direct, consistent fit within the engine assembly. This piston is the 0.75 oversize option, intended for engines that have been bored out during a rebuild to restore proper compression and performance. Confirm your engine's bore measurement before ordering to ensure this is the correct oversize specification for your application.
Key Features
- Genuine OEM Oversize Specification: — Factory-sourced to the exact 0.75 oversize dimension, ensuring correct compression ratio and ring seal for a rebuilt engine bore.
- Direct Engine Rebuild Fit: — Designed to drop into a properly bored cylinder on CA-4-4H, MC44S, and CA4HM engines without secondary machining when the bore matches this oversize spec.
- Verified Fitment: — Compatible with CA-4-4H walk-behind trowels, MC44S concrete mixers, and CA4HM walk-behind trowels sharing the same engine platform.
- Restored Power Output: — A correctly sized oversize piston seals the combustion chamber fully, recovering lost compression and engine power that results from cylinder wall wear.
- Engine Longevity After Rebuild: — Using the correct OEM oversize piston during a bore-and-rebuild service extends engine service life and prevents premature ring and cylinder wear.
A piston transfers the force of combustion into mechanical motion by moving up and down within the engine cylinder. Over time, cylinder walls wear and lose their original tolerance, causing compression to drop and power to fall off — a cylinder bore and oversize piston installation restores that fit. The 0.75 designation on this piston indicates it is an oversize option, intended for use after a cylinder has been bored to that corresponding oversize dimension during an engine rebuild. Selecting the wrong oversize will result in improper ring seal, oil consumption, or engine damage, so always verify the bore measurement before specifying this part.
