1098100621 Isuzu BEARING; PIN, Price: 76.68$, Weight: 1.218kg

Precision Pin Bearing for Isuzu Engines ?

This small-end bearing supports the wrist pin inside the connecting rod, keeping the piston aligned and friction low. It is essential during every power stroke, carrying heavy loads while allowing smooth oscillation. Ideal for engine rebuilds and preventive maintenance, it restores quiet operation and protects cylinder walls.

How it works ⚙️

The part is a precision-machined bushing that sits in the rod’s small end. An oil film forms between the wrist pin and the bearing’s micro-finished bore, dispersing heat and preventing metal-to-metal contact. Correct clearance, hardness, and concentricity ensure stable piston travel, clean combustion, and long service life.

Why you need it ✅

Worn pin support leads to tilt at the piston crown, rising noise and blow-by, and accelerated wear across the skirt and cylinder. Replacing it during overhaul locks in factory geometry and reduces vibration.

Symptoms of wear or failure ?

• Cold-start ticking, light knock under load
• Excess play at the rod small end
• Metallic flakes in engine oil
• Piston scuffing, abnormal skirt marks

Consequences if ignored ❌

Progressive clearance becomes seizure or pin walk, scoring the cylinder and possibly cracking the rod—leading to catastrophic engine failure and costly downtime.

Fitment and quality ?

Built to OE spec for Isuzu diesel applications, ref 1098100621. Hardened alloy, tight tolerances, oil-groove geometry for reliable lubrication.

Installation tips ?️

Press-fit with proper support, align oil holes, check pin-to-bush clearance, and pre-lube on assembly. Always measure, hone if required, and torque to spec. Replace in sets for balanced wear.
