Why is my DT 466 getting hard to start?
The 466 uses oil to hydraulicly actuate your injectors. Once the o-rings start to leak, the high pressure pump has a hard time building pressure to actuate the injectors. Sometimes it takes 30 seconds to finally build enough pressure to start. This is about a 2 hour job at a dealer. Did you check ALL fluids accurately?
Is the IH 4300 DT466 getting hard to start?
I have an 05 IH 4300 DT466 with 131K miles on it. I have had a small problem with it before, usually first thing in the AM. But now it doesn’t want to start no matter what time of the day it is. If its been sitting for any length of time it cranks and will finally start after about 45 seconds.
Why does my DT466 stall out on the road?
That’s usually the culprit on DT466’s stalling out. Cam sensors cause no start and dying on the road HOT, it is possible but very rare to have a CPS problem cold. Also, unable to build ICP is a code, it does not tell you when it happened or what the *cause* was.
What should off hand rpm be on DT466?
If it cranks don’t rev it unless you have a gauge to handle about 3000psi. Off hand should take close to 600psi to start. also you can pull the valve cover and apply shop air pressure into the rail and look for air bypassing the injectors.
What are the crank times on a 2005 DT466?
We have 2 of the 2005-2006 DT466s, when cold, long cranking times then an unnerving high speed rev up and black smoke till they settle down are the norm. They are one of the reasons we switched to 5W-40 motor oil, both to make me feel better about the cold high speed rev up and to help with the cold cranking speed.
What kind of car is the DT 466?
Can’t seem to figure this one out myself, so I figured I’d try here. 2003 International 4300 with the 466, and have been having some issues. Used to start and run beautiful, probably the best running dt I’ve driven.
Where is the starter on a 2004 DT466?
If you start from behind the head and start feeling downwards and onto the bell housing you will see that it is mounted with one small bolt at about the 11 o’clock position . It is above the starter by about 12 inches for sure but right on top of the bell housing .
What should fuel psi be on dt466e International diesel?
Usually when we get no start cold but fires and runs after using ether it might be injectors, but you need to do the fuel checks I posted and let me know. If you don’t have a fuel psi gauge, autozone loans them out. I like to have around 60psi I have seen them run ok above 45psi.
How often does a DT466 give up the ghost?
The only difference betwene the two is how light your pocket will be. If its not the issue youre only out 25 or 30 bucks. Had mine go a couple times they usualy give up the ghost every 50,000 to 100,000 as long as you dont run too hot and driving conditions.
What makes a DT466 diesel truck go limp?
The engine is new, the injectors are all new, the MAP Sensor is new, the Baro Sensor is new, the Cam Sensor is new, the High Pressure Oil Pump is new, the fuel sensor and regulators are new, the computer is new. The truck will crank, and then go into a limp mode and blow tons of white smoke out of the stack. Any ideas would be appreciated.
Why does my dt466e have no oil pressure?
Pulled the tube and checked it. It was fine. Pulled the engine oil pump (on crank) and it looks worn. Light grooving and some wear on the gear lobes in the pump. Leaning towards that being it. With it not filling the front cover i don’t think it’s the pressure Reg but i could be wrong.
What do the 0-rings on a DT466 mean?
Looks like you need a set of injector 0-rings. those codes refer to loss of injection pressure. The long rail on the side of the head is the High pressure rail for the injectors. If you have a gauge that goes up to 1000psi or better you can tap into the pressure sensor port and check cranking pressure.
How long does it take to start a 05 dt466e bus?
I have 11 05 DT466E buses in my fleet. Out of the 11, only 4 like to start. The rest have extended cranking times. sometimes it takes up to 45 seconds of cranking to get them started, and the cold only makes it worse.
