🛠️ Important Technical Note for Mechanics (Housing Clocking):
This turbocharger is shipped out of the box clocked (angled) to directly replace 277-6368 (750525-5014S). However, because it shares the exact same core architecture with the opposite-side turbo 277-6367 (750525-5013S), it can also be used for the other side.
If you are replacing a 277-6367, simply loosen the housing clamps/bolts upon arrival, rotate (clock) the compressor/turbine housing to match your old unit’s angle, and re-tighten.

⚠️ Important Installation Notice:
To prevent premature turbo failure and validate your 2-Year Warranty, your technician must strictly follow these critical procedures during installation:
-
💧 Pre-Lubricate (Oil Priming): Crucial Step! Before connecting the oil lines, inject fresh, clean engine oil into the oil inlet port and spin the compressor wheel by hand. This prevents dry-start bearing damage during the first startup.
-
🧼 Clear Air System & Intercooler: If the previous turbo suffered a mechanical failure (broken blades/shaft), metal debris may be trapped inside the Charge Air Cooler (CAC) or intake piping. You MUST flush the intercooler. Leftover particles will be sucked into the new unit, causing catastrophic wheel damage.
-
🪠 Check Oil Drain & Crankcase Breather: Ensure the oil return line is clean and unkinked. A restricted drain line or high engine crankcase pressure will prevent oil from exiting, forcing it past the turbo seals and causing immediate oil leaking or smoking.
-
🆕 Always Replace Oil Feed Lines: Never reuse the old oil feed line. Old lines often contain trapped carbon deposits and sludge that will restrict oil flow, starving your new turbo of lubrication.
-
🔧 Certified Mechanic Required: Installation must be performed by a licensed heavy-duty technician. Please retain your professional service invoice and oil change receipt for warranty validation.
