I have a Garrett T45 that is causing problems.
I purchased it in a private deal - not from a company, although it was brand new and still sealed in shrink wrap.
The problem is that although it spins freely, smoothly and silently, with no play, when the bearings are fed with pressurised oil from my oil pump, the turbine stops dead and can only be turned with the fingers by using considerable force. Upon ceasing the oil feed, the turbine immediately spins freely once again.
My oil pressure is approximately 40 p.s.i.
Can anyone advise me of the possible cause of this problem...... I have tried "running it in", using an electric motor to spin it at a few hundred rpm for half an hour or so, but it hasn't improved the situation.
Should the oil pressure be less ?
I'd appreciate your comments.
Thanks -
Richard Barton.
