Question about oil pressure and restarting engines

[mtwomey]

I'm new to this and I've spent all day working through the startup procedures (having fun). I've have question about this:

 

In the manual in the Main Engine Start-Up section, it states:

 

"Upon reaching normal oil pressure in the engine gearbox, the green “Р масла ПРИВОДОВ” (gearbox oil press norm) light will illuminate."

 

For the life of me, I cannot find any such "light" or any further references to it - am I just missing something?

 

Also, as I'm practicing starting up and shutting down, sometime I get myself into a state where I can't seem to start the engines. After I press start, the RPMs will increase to just over 20%, but when I open the cut-off valve it doesn't ramp up. This only seems to happen after I've started and stopped the engines a couple of times and I'm thinking it means there is something additional I need to do. I've tried the False Start and Crack procedures, but they don't seem to help. Any thoughts on this?

 

Thanks,

Are you referring to the oil pressure light for the APU on the APU panel?

Also try to start the engine at about 18%, I have found it works better and you have less chance of damaging the engine. Also once you have started the engine, wait for it to stabilize (i.e. EGT to stop rising and RPM to do the same) Also wait for engine to reach 0% RPM before attempting to re start. I hope this helps in some way.

No - it specifically says the green gearbox oil press norm light. This is on page 5-11 of the PDF manual.

 

Thanks for the tip on the slightly earlier start (at 18%), that does seem to be a better overall strategy than accidentally waiting too long - but I still can't get the thing going sometimes after I shut it down.

Are you 100% sure you did the false start and crank procedure right? If that doesn't render the engine startable, it must have been damaged. I don't know for what reason though.

Aint that light on the overhead panel ? Top right of that panel.

No - I'm not 100% sure I did these procedures correctly. I did follow them step by step in the manual but there seems to be a slight translation issue on the crank procedure which is confusing me. On page 5-13 is says:

 

"The main engine crank procedure is analogous to the false start procedure but with the only difference being that the fuel cut-off valve is closed. Its purpose is to vent fuel from the combustion chamber."

 

It says the fuel cut-off valve is closed, then just below this (in the numbered steps) it says:

 

"Open the fuel shut-off valve of the cranked engine..."

 

I think the intent is to have the engine cutoff valve closed and the fuel cutoff valve open - correct or should this be the other way around?

You're right! Actually on the left overhead panel on the bottom right. I missed it while searching the PDF because it was referred to slightly differently.

 

Thanks!
