The Multiquip 12910023910 Piston Pin Bush is a genuine OEM component designed for T23, T26, and T33 ride-on rollers. As a direct OEM replacement, this bush is manufactured to the exact material and dimensional specifications required by the original engine assembly, ensuring a correct installation without modification. Sourced through Multiquip's authorized parts network, the part is the verified replacement for machines where precision fit at the piston pin bore is critical to engine longevity and output.
Key Features
- OEM Material Specification — Manufactured to the exact bearing material grade and wall tolerance required at the piston pin interface, maintaining proper oil film and load distribution.
- Drop-In Replacement — Matches the original bore diameter and press-fit specification of the factory bush, seating correctly into the connecting rod small end without rework.
- Confirmed Fitment — Verified for T23, T26, and T33 ride-on rollers; use part number 12910023910 to confirm compatibility with your specific unit.
- Engine Performance Protection — A worn or failed piston pin bush causes excessive piston slap, accelerated bore wear, and loss of compression — replacing it restores smooth, stable power delivery.
- Fuel System and Combustion Integrity — Correct pin-to-bush clearance is essential for maintaining proper combustion geometry and preventing premature wear on the piston, pin, and rod assembly.
The piston pin bush is a precision bearing sleeve pressed into the small end of the connecting rod, providing a controlled bearing surface for the piston pin as it pivots during the engine's stroke cycle. It absorbs the lateral load transferred between the piston and the rod, and the tight clearance it maintains is essential for consistent compression and smooth power transfer. When this bush wears or fails, excess play at the pin joint leads to knocking, accelerated internal engine damage, and ultimately loss of power or engine failure.
