The Multiquip 1622421110 Piston is a genuine OEM component designed for BLW-400SSW, KD1800, KD1800KD6, and KD6 series equipment. As a direct OEM replacement, it is manufactured to the same specifications as the original part, ensuring a correct installation without the guesswork of aftermarket alternatives. Sourced direct from Multiquip, this piston is the trusted choice when restoring engine performance on compatible machines.
Key Features
- Genuine OEM Construction — Manufactured to the exact material grade and dimensional tolerancing of the original, ensuring the piston seats, seals, and cycles correctly within the cylinder bore.
- Direct-Fit Installation — Engineered to the same bore diameter, ring groove spacing, and pin dimensions as the factory original, dropping straight into the cylinder assembly of compatible equipment.
- Confirmed Fitment — Compatible with BLW-400SSW, KD1800, KD1800KD6, and KD6 series machines; use part number 1622421110 to verify against your model.
- Restored Compression and Power Output — A worn or damaged piston causes loss of compression, increased oil consumption, and rough running; replacing it with the correct OEM part restores proper cylinder pressure and consistent power delivery.
- Engine Longevity — Correct piston fit minimizes blow-by, reduces wear on cylinder walls and rings, and supports the full service life of the engine assembly.
The piston is the reciprocating component inside the engine cylinder that converts combustion pressure into mechanical force, driving the crankshaft and ultimately powering the machine. It works in close tolerance with the cylinder bore and piston rings to maintain compression and control oil consumption. When a piston wears, cracks, or scores, compression drops, fuel efficiency suffers, and the engine may smoke, misfire, or fail to develop full power — making prompt replacement critical to keeping the engine running at peak performance.
