Sealed Power uses modern materials and ISO- and QS-certified manufacturing processes to produce parts that meet the demands of today’s engines. This part cross-references BB1435 and CB1781A4 for the same application. Fits 1995-2004 Toyota Tacoma, N/A; Fits 1996-2000 Toyota 4Runner, N/A; Fits 1994-1998 Toyota T100, N/A; Fits 1991-1995 Toyota Previa, N/A.

Common Repair Uses

• Restores worn connecting rod bearing surfaces during engine overhaul
• Addresses rod knock caused by bearing wear or loss of clearance
• Supports proper oil film control in high-mileage Toyota engines
• Helps correct scoring or damage found during bottom-end inspection
• Replaces bearings that no longer hold standard journal fitment

Installation Notes and Tips

Verify crankshaft journal size, housing bore, and oil clearance before assembly. Clean all mating surfaces thoroughly and measure each rod and journal during installation to confirm the standard-size bearing selection matches the engine specification. For Toyota Tacoma, 4Runner, T100, and Previa applications, confirm the engine configuration and service measurements against the vehicle’s rebuild requirements before final assembly.
