The Multiquip 13011ZF1023 is a genuine OEM Piston Ring Set OS 0.25 Optional designed for a wide range of Multiquip equipment including MP1455HP, MP120E, MP115E, MP1H, WM70S/P, GAC2.2HZ, MVC90H, and QP205SH. As a direct OEM part, 13011ZF1023 is manufactured to the same specifications as the original ring set, ensuring a proper fit within the engine bore without the need for guesswork. This oversized 0.25 option is intended for use during engine reconditioning when the cylinder has been bored out to accept a larger piston. Sourced directly through authorized Multiquip supply channels, DHS Equipment stocks this part ready for order.
Key Features
- Genuine OEM Ring Tolerancing — Manufactured to exact gap clearance and compression height specs for the engine family shared across these Multiquip models, ensuring proper ring seal against the cylinder wall.
- Oversized 0.25 mm Bore Specification — Sized specifically for cylinders that have been bored 0.25 mm over standard, making this the correct choice for engine rebuilds on worn or scored bores.
- Broad Equipment Compatibility — Fits MP1455HP, MP120E, MP115E, MP1H, WM70S/P, GAC2.2HZ, MVC90H, and QP205SH, covering masonry saws, mortar mixers, generators, plate compactors, and centrifugal pumps in the Multiquip lineup.
- Restores Compression and Engine Output — Worn piston rings allow blow-by, causing loss of compression, increased oil consumption, and hard starting. Replacing with a correctly sized OEM ring set brings cylinder pressure back to operating spec.
- Complete Set Included — Supplied as a full ring set for the piston, so all rings are replaced together during rebuild, maintaining consistent sealing performance across the entire ring pack.
Piston rings form the dynamic seal between the piston and the cylinder wall, serving three critical roles: containing combustion pressure to drive the piston, controlling oil from entering the combustion chamber, and transferring heat from the piston into the cylinder wall. Over time and high operating hours, rings wear thin, lose tension, or develop gaps that exceed specification — this allows combustion gases to leak past the piston (known as blow-by), which robs the engine of power, increases oil consumption, and causes rough running or hard starts. During an engine overhaul where the cylinder has been bored to remove scoring or wear, the standard-size rings will no longer seal correctly against the enlarged bore, making an oversized ring set like the 13011ZF1023 OS 0.25 the required replacement to restore proper engine performance.
