FAQ

Q1: How can I confirm that these bearings (8-98089084-0 and 8-98051928-0) will fit my Isuzu 4LE1 or 3KR1 engine?

To ensure correct fitment, remove your old bearings and check the part numbers stamped on them. They should match 8-98089084-0 for the main bearing and 8-98051928-0 for the connecting rod bearing. Additionally, verify your engine model is either 4LE1 or 3KR1 by checking the engine nameplate. These bearings are designed to OEM standard size; if your crankshaft has been previously ground undersized, you may require undersized bearings instead.

Q2: What installation precautions should I take when installing these main and con rod bearings?

Always clean the bearing saddles and caps thoroughly before installation. Apply a thin layer of clean engine oil to the bearing surfaces during assembly. Tighten main bearing cap bolts and connecting rod cap bolts to the manufacturer’s specified torque settings using a calibrated torque wrench. Never mix old and new bearings, and always replace all main and rod bearings as a complete set during an overhaul.

Q3: What is the typical service life of these bearings, and when should they be replaced?

Bearing life depends on operating conditions, maintenance, and oil quality. In heavy-duty applications like excavators and forklifts, these bearings typically last 4,000-8,000 operating hours before requiring replacement. Signs of wear include knocking noises from the engine, low oil pressure, or visible scoring on the bearing surface during inspection. Always replace bearings when performing a major engine overhaul or if you notice any of these symptoms.
