FAQ

Q1: How do I confirm this 33T oil pump gear fits my Caterpillar engine?

A: This gear (294-1729) is designed for the C6.4 engine. To confirm fitment, check the part number stamped on your existing oil pump gear. It should match “294-1729”. Alternatively, verify your engine serial number prefix against Caterpillar’s C6.4 parts catalog. If your gear has a different number of teeth (e.g., 32T or 34T), this part will not be compatible.

Q2: What is the installation procedure for this oil pump gear?

A: Installation requires mechanical experience. Key steps include: (1) Drain engine oil and remove the oil pan and front cover. (2) Remove the retaining bolt or nut securing the old gear. (3) Use a gear puller if the old gear is seized. (4) Clean the shaft and apply a light coat of clean engine oil. (5) Press or slide the new gear onto the oil pump drive shaft, ensuring it is fully seated. (6) Torque the retaining fastener to factory specifications. Always replace the oil pump seal and gaskets during this service.

Q3: Does this gear require any special break-in or maintenance?

A: No special break-in is required beyond standard engine start-up procedures. After installation, run the engine at idle and check for proper oil pressure. Inspect for any unusual noise from the timing cover. For maintenance, follow your engine’s standard oil change intervals. Using clean, high-quality engine oil will maximize the life of this gear. If you notice metallic debris in the oil filter during subsequent changes, inspect the gear teeth for wear.
