Low oil pressure 6CTA 450
This topic has 8 replies, has 4 voices, and was last updated by 6 months ago
August 28, 2023 at 4:04 am Hi, I’ve got a low oil pressure problem on one of my 450s, After a run at cruise and slowing down to idle, alarm will sound, on port engine. I disconected the Cummins panel alarm a few years ago, as it was always alarming, even with 20PSI at idle. I just use a stand alone 10 psi switch, on the back up Aqua alarm panel. Engines have 7,000 hours on them and have been serviced regularly, their whole lives. Anyone have any ideas? …

CTA 450 cylinder head torque
This topic has 2 replies, has 2 voices, and was last updated by 2 years ago
October 9, 2021 at 3:39 am Hi, I have blown the head gasket on my 450 and am about to dive into removing the head, etc. I found the link under Tony’s tips for the head torque procedure and it lists the values for 26 bolts. The diagram shows 32 bolts. What is the procedure/torque values for the remaining 6 bolts? Thanks, Cam
