The Multiquip 13011ZF6003 is a genuine OEM Piston Ring Set OS 0.25 Optional designed for the MRH800GS roller and WM120SH, WM120PH, EM120S Series, and EM120P Series mixer models. As a direct OEM replacement sourced through authorized channels, this oversize ring set is engineered to restore proper compression and oil control in engines that have been bored or honed to the 0.25mm oversize specification. Confirm your engine bore size before ordering to ensure this oversize set matches your specific rebuild requirements.
Key Features
- Genuine OEM Compression Tolerancing — Manufactured to the exact ring gap and tension specifications required for correct cylinder seal, ensuring consistent combustion pressure after an oversize bore.
- Oversize Rebuild Fitment — Sized at OS 0.25mm to drop directly into a properly bored or honed cylinder without additional machining or fitting adjustments.
- Broad Model Coverage — Compatible with MRH800GS, WM120SH, WM120PH, EM120S Series, and EM120P Series equipment, making it a practical stock item for fleet maintenance operations.
- Engine Compression Restoration — Worn or broken piston rings allow combustion gases to bypass the piston, causing power loss, excessive oil consumption, and hard starting; a fresh ring set brings compression back to proper operating levels.
- Verified OEM Part Number — Part number 13011ZF6003 matches Multiquip's current OEM parts catalog, so you can order with confidence that this is the correct set for the listed equipment families.
Piston rings seal the gap between the piston and the cylinder wall, maintaining the compression needed for efficient combustion while also controlling how much oil reaches the combustion chamber. A complete ring set typically includes compression rings and an oil control ring, each performing a distinct sealing role. When rings wear, lose tension, or break, the result is reduced power output, increased oil consumption, blue exhaust smoke, and difficulty starting — all signs that a ring replacement or engine rebuild is due.
