Multiquip 2772351317 Piston Ring Set Oversize 0.50 MM

The Multiquip 2772351317 is a genuine OEM Piston Ring Set Oversize 0.50 MM designed for G-2.9R, GA-2.9R, MVC82VE, MVC82VEW, and QP-2TE series equipment. This is a direct OEM replacement sourced through Multiquip's authorized parts program, ensuring the set matches the exact oversize specification required for engines that have been bored to the 0.50 MM oversize tolerance. Verified fitment across portable AC generators, plate compactors, and trash pump applications means you can order with confidence knowing 2772351317 is the right ring set for your engine rebuild.

Key Features

• OEM Oversize Specification: — Manufactured to the exact 0.50 MM oversize tolerance, ensuring correct ring-to-bore clearance and proper compression seal after an engine bore job.
• Drop-In Engine Rebuild Fit: — Engineered to seat correctly in a 0.50 MM overbored cylinder without additional machining or fitment adjustment at installation.
• Broad Equipment Compatibility: — Confirmed for G-2.9R, GA-2.9R, MVC82VE, MVC82VEW, and QP-2TE models, covering portable generators, plate compactors, and trash pumps sharing the same engine platform.
• Restored Compression and Oil Control: — Fresh piston rings restore the compression seal and oil film control that worn rings can no longer maintain, directly recovering lost engine power and fuel efficiency.
• Combustion Integrity: — Worn or broken piston rings allow combustion gases to bypass into the crankcase, causing oil contamination and accelerated engine wear; replacing with the correct OEM set stops blow-by at the source.

Piston rings create the critical seal between the piston and the cylinder wall, performing three jobs simultaneously: containing combustion pressure above the piston, regulating the thin oil film on the cylinder wall, and transferring heat from the piston into the cylinder. When rings wear, lose tension, or break, combustion gases escape past the piston — a condition known as blow-by — resulting in loss of power, increased oil consumption, and contaminated crankcase oil. An oversize ring set like the Multiquip 2772351317 is used specifically when the cylinder has been bored out to 0.50 MM over the standard diameter to restore a round, smooth surface, and these rings are sized to match that rebored bore precisely, returning the engine to full compression and efficient operation.
