ATP Engine Harmonic Balancer P/N:102251
Tame crankshaft vibration and keep the accessory belt tracking true with the ATP engine harmonic balancer (P/N 102134). It installs as a direct-fit replacement on the 1995-1998 Nissan 200SX [L4-1.6L] and 1995-2000 Nissan Sentra [L4-1.6L], and ATP states its balancers fit and function like the original part.
A harmonic balancer's job is to absorb the crankshaft's torsional vibrations. These units are typically built in three pieces: a hub that bolts directly to the crankshaft, a rubber or fluid damping layer around it that soaks up vibration, and an outer metal ring grooved for the drive belt. Over time the rubber and/or fluid layer can deteriorate, letting the outer pulley shift forward — which can cause belt misalignment and, if left unaddressed, contribute to crankshaft damage.

What vehicles does the ATP harmonic balancer 102134 fit?
It is a direct-fit replacement for the 1995-1998 Nissan 200SX [L4-1.6L] and the 1995-2000 Nissan Sentra [L4-1.6L]. Always confirm fitment for your vehicle before ordering.
What does a harmonic balancer do?
It absorbs the crankshaft's torsional vibrations. A damping layer between the crank-mounted hub and the grooved outer pulley soaks up those vibrations to help keep the crankshaft and drive belt running smoothly.
What are signs my Nissan Sentra harmonic balancer may need replacing?
Watch for belt wobble or misalignment, vibration, or a visibly separated or shifted outer pulley ring — signs the rubber or fluid damping layer has deteriorated. Diagnose the cause before replacing.
How is the ATP engine harmonic balancer built?
Harmonic balancers are typically made in three pieces: a hub that bolts to the crankshaft, a rubber or fluid damping layer, and an outer metal ring with grooves for the drive belt.
What numbers does this ATP balancer interchange with?
It cross-references PB1107-N, DA-40, PC5000, 594143, 30950228, 6005296, 123030M210, DA40 and V1156. Match the number to your original part to confirm the correct unit.
