TURBOCHARGER LUBRICATION SYSTEM PRIMING
Immediately prior to mounting the unit, prime the lubrication system as follows:
1. Invert turbocharger and fill center housing with new clean oil through oil drain.
2. Turn rotating assembly by hand to coat bearings and thrust washer with oil.
3. Coat threads of attaching bolts or studs with high temperature thread lubricant.
4. After installing turbocharger, flush oil through oil inlet line and ensure that line is clean and unob-
structed.
5. Fill engine and oil inlet line with new, clean lubricating oil, and connect line.
6. Connect oil return line.
– NOTE –
If the turbocharger is to be installed on a new or newly over-
hauled engine, operate the engine with a separate oil filter in
the oil supply line to the turbocharger during the first hour of
operation. This must be done to ensure that no metal particles
are carried from the engine into the turbocharger lubrication
system.
