FAQ

Q1: How do I confirm that this injector push rod (391834) fits my Caterpillar 3116 engine?

A: We recommend comparing the part number 391834 with your existing push rod. Measure the overall length, diameter, and end configuration. Additionally, verify your engine’s serial number against Caterpillar’s parts catalog. If you have any doubts, contact our support team with your engine model and serial number for cross-reference assistance.

Q2: What is the installation procedure for this injector tappet?

A: Installation should be performed by a qualified diesel mechanic. General steps include: (1) Remove the valve cover and access the injector area. (2) Carefully extract the old push rod. (3) Lubricate the new push rod ends with clean engine oil. (4) Insert the new push rod, ensuring it seats properly in the lifter socket and rocker arm. (5) Adjust valve lash to manufacturer specifications if required. (6) Reinstall the valve cover and torque to spec. Always refer to the engine service manual for exact procedures.

Q3: What maintenance is required for injector push rods in Caterpillar 3116 engines?

A: Injector push rods are wear items that should be inspected during routine valve adjustments or major overhauls. Signs of wear include bent shafts, pitted ends, or scoring. We recommend inspecting push rods every 1,000-2,000 operating hours or as per the engine maintenance schedule. Using high-quality engine oil and maintaining proper valve clearance will extend push rod life.
