Can I drive my Cummins with a bad turbo actuator?
Yep fine to drive, assuming no actual physical mechanical thing has gone wrong (which you’d definitely have known).
What is a VGT on a Cummins engine?
In 2007, Dodge trucks began using the 6.7L common rail Cummins diesel turbocharger engine, which uses a Variable Geometry Turbocharger (VGT). On the 6.7L, the VGT has a patented one-piece sliding nozzle that continuously moves to vary the power of the turbine and the amount of air delivered to the engine.
What does a VGT actuator do?
The VGT actuator moves either vanes or a sliding sleeve inside the turbocharger which increases or decreases exhaust gases driving the turbine wheel, which in turn, increases or decreases turbo boost based on engine operating conditions. Calibrating turbocharger actuator to turbo charger.
What is a common cause of VGT actuator motor failure?
SREA and REA will fail because of the variable geometry mechanism sticking due to sludging or carbon build up. When the variable geometry mechanism sticks, it pulls a higher current through the motor than it is designed to take, this therefore causes the motor to burnout or the plastic worm gears to fail.
What’s the difference between a VGT and non VGT turbo?
A VGT turbo has an electrical solenoid that actuate a set of vanes for optimizing exhaust flow to the turbine wheel for spool up where a Non-VGT turbo just has a turbine wheel that must be spooled with however fast and hot the exhaust gases enter the housing.
Can a turbo actuator be repaired?
As part of many Turbo Manufacturers “No Repair Policy”, if you have a faulty Electronic Turbo Actuator, it would mean you would have to replace the complete Turbocharger as the Turbo Actuator itself will not be available on its own.
Do you need to calibrate turbo actuator?
It is important to note that most electronically controlled VGT actuators will need to be calibrated once removed or replaced.
Can you tow with a non VGT turbo?
It towed great for me, it just did not like being under 2000rpms (but towing heavy with any load should not spend a lot of time under 2000rpms IMO). Lots of guys love the non-vgt and swear by them. But you will experience a difference in driving style because it takes a little longer for the turbo to get going.
What to do when a VGT actuator fails on a Cummins?
On some specific Cummins engines, a fault over VGT (Variable Geometry Turbine) actuator needs a specific procedure to correctly achieve reparation. This specific procedure must be followed also when the VGT actuator is removed and reinstalled. Voice your opinion!
What does the VGT actuator code 2636 mean?
The VGT actuator code 2636 stated that the actuator was inoperable because of a message interruption through the J1939 which is how the engine ECU communicates to the actuator. We went through the troubleshooting steps using the Cummins Quickserve website and checked the wiring harness.
Is there a remanufactured version of the Holset he351ve VGT actuator?
If so, we offer a remanufactured option for the Holset HE351VE VGT Actuator that includes the installation kit and gaskets for all 2007.5 through 2012 Dodge 6.7 Liter Cummins Engines. This turbo actuator is also found in Freightliner trucks with the 6.7 Liter Cummins Engine.
What does code 2636 mean on a Cummins?
Eventually mechanical components do fail as most people know and this part was the VGT actuator. VGT stands for variable geometry turbocharger. Cummins Code 2636 VGT Actuator | Mechanics Hub
