8h with fuel oil torque

There is a procedure for filling the torque converter when drained...
Open the crossover valve and vent on the converter.
Fuel supply being higher than the converter, allows the fuel to be gravity fed through the cross over valve.
I can't tell you exactly where the valve is other than follow the main fuel supply line from the tank and it tees off the line after the primary filter.

Hi Team,
these scans from my Grey D8H 46A1 To 46A3044 OMI Form No 33515-4, Dated 5-52.
The - (dash) number after the initial Form No gives the iteration of the Form No--so the higher the - (dash) number the later the information in the Book.

Hope they help.

Note also in the scans the expected seal drip leakage rate for the TC, both when running and stopped.

As the fuel in the fuel tank will be hot at the end of a days operating the fuel tank should be topped off so as to minimize air in the fuel tank to cool and so draw in moisture laden air overnight--condensation in the fuel will damage fuel and T/C components in short order.

You may have an air leak in the fuel tower or such, that allows the fuel to drain back via the T/C seal drains--also an air leak at the T/C bleed Valve could let air in here.

You may just have to let the T/C leak and catch the fuel and use it for cleaning etc. if you cannot find an air leak in the rest of the fuel system.

I could see air getting into the TC via the seals when under vacuum, I see in the diagram that used T/C fuel is cooled and excess goes back to tank via the bleed orifice and so should not reach the engine directly--hence my thought on an air leak at fuel tower etc in the engine fuel system--it will be under vacuum too due to the T/C seals leaking and the fue tank tap being off as well as being tied into the T/C fuel system if you follow me.
Bit garbled as I am at present.

Hope this helps,
Cheers,
Eddie B.

Thank you gentlemen.
This cat is a power shift if it makes any difference in bleeding the torque converter.
Ithe will be a while before I get back to the cat but the pages posted should be a big help.

Thanks again
Scott

The D8H powershift does not use a fuel torque converter.

O but yes they did. About 3000 of them.
