FAQ

Q1: Will this connecting rod (8-94333-119-0) fit my Isuzu 4JA1 engine without modification?
A: Yes, this rod is manufactured to OEM specifications and is designed as a direct replacement for the original Isuzu 4JA1 connecting rod. It should bolt in without any modification, provided your engine uses the standard OEM size rod. We recommend verifying your existing part number (stamped on the rod) matches 8-94333-119-0 or 8-94333-119-3 before installation.

Q2: What is the recommended installation procedure for this connecting rod?
A: Installation should follow standard diesel engine rebuild practices. Key steps include: cleaning the rod and cap mating surfaces, torquing the connecting rod bolts to the manufacturer’s specification (typically 45-55 Nm for 4JA1 rods, plus an additional angle-tighten step), checking side clearance, and verifying that the big-end bearing shell is correctly seated. Always use new rod bolts and nuts if specified by the engine manual. We recommend consulting the Isuzu 4JA1 service manual for exact torque values and procedures.

Q3: How can I confirm this is the correct rod for my engine if the part number is worn off?
A: If the original part number is illegible, you can confirm fitment by measuring the rod’s critical dimensions. For the 4JA1, the big-end bore diameter is typically 53.0 mm, the small-end pin bore is 28.0 mm, and the center-to-center length is approximately 152.0 mm. You can also check the engine serial number against Isuzu parts catalogs. If unsure, contact our technical support team with your engine model and serial number for verification before purchasing.
