DT 466 How To Advance Timing

The older DT 466 Timing Advance procedure is not that hard since it's a mechanical injection fuel system. The electronic age has not yet entered this DT 466's world yet. If you haven't seen or worked around this engine model, I have to give it a thumbs up for low cost and how easy they are to repair.

They are bullet proof and just a one in a million design that got shut out by the new emission standards of today. I'm not against the new environment age but it sure was nice having these jewels in our fleet.

Watch the Diesel Mechanic in the video below and see how easy it is to work on the DT 466 diesel engine.

Vehicles Pollute Even When They're Parked?






So here I was cruising through some Google News articles and came across this report about vehicles in Australia in the millions that do not have the proper evaporative emission canisters to trap hydrocarbons before they escape from the fuel tank into the atmosphere. Even new vehicles that have the right equipment fill up with gases and spew out the excess build up after sitting for 24 hrs.

Quote:
Hydrocarbons are in the vapour that escapes from petrol tanks on a warm day. Most newer cars have canisters that trap them before they are released but if cars are left sitting for longer than 24 hours the canisters can fill up and stop working until the vehicle is driven, the Second National In-Service Emissions Study found.
Unquote:

This interesting fact makes me think of the grandfathered vehicles out there that don't meet emission standards that will not only pump out carbon monoxide but also emit hydrocarbon fumes out the tank if left idle over 24 hours.

So I guess we will have to weigh the difference between going the public transit route or driving to work to clear out all those nasty destructive gas fumes. If you ask me I thing taking the subway or bus is a greater benefit overall.

The Best Diesel Engine-DT 466 International School bus

The Best Diesel Engine? By far the DT 466 by International. For the Medium Duty fleet operator this engine is the most reliable of all. Pictured is the DT 466 E [electronic version]. Each injector is controlled electronically by the engine ECM and injection is actuated by high pressure oil. These injectors are HEUI [hydraulic electronic unit injector] that are reliable but typically have to be resealed if there's a fuel in the oil problem...for example.














Here I'm setting valves which is .025 for both the exhaust and intake. One of the differences with the electronic engine and the older non-electronic models is the newer engines have the intake manifold built into the valve cover so it weighs much more, making it difficult to remove. There is the Engine Control Module as well fastened to the valve cover on the driver side.

Below is an electronic unit injector that can be tested while running with a laptop for proper injection cycles.















On the International School Bus the dog house inside the cab also has to be removed to gain access to the rear cylinders. This aside the reliability of the DT 466 E and older DT 466 in my opinion is the most reliable model for a medium duty fleet operation. One characteristic with the electronic version is a very rough start up in cold weather because of the engine oil pressure feeding the high pressure system. It takes a bit of high idling to get smooth fuel injection happening.

If you can find a mechanical DT466 then you have reached diesel heaven! With no HEUI and a Bosch fuel injection system you will have very dependable power unit. I can remember in-framing these engines for $1200.00 they are very basic and easy to work on. But technology has taken over and fuel emissions are here to stay.
