yes the procedure is in the manuals.

with a completely full fuel tank they can gravity bleed somewhat too but that is a lot of fuel i cant remember the figure in gallons but my 6u holds 120 litres so it adds up fast.

the tire tube idea works well.

I believe i read somewhere that it holds 20 US Gallons. It was dry when i inspected the tank, i put 5 gallons in to rinse the critters out, but... the line is plugged, probably with more critters

Hello! Well 7 months later i finally have 8143 back together with a working fuel transfer pump and rebuilt starter pinion (big thanks to Squatch for the amazing videos, i reconditioned the starter pinion verbatim and it works great!!)

Here's the issue. After warming up the starting motor, engage the main engine and start the fuel bleeding process. Previously i had drained the remaining fuel from the tower and checked the filters. Tower is pretty darn clean so closed it up and proceeded. After about 5 minutes, had fuel at the front bleeder, another couple minutes i had fuel at the top side bleeder. Fuel pressure guage indicated high caution/low normal at this point. Opened the injector lines and waited.. and waited... No fuel from injector lines. Opened throttle, waited. nothing. 

Re-read for the 15th time, the Neils directions for bleeding.

Question: are there specific bleeders on the injection pump i should be opening? If so, where/which are they?

Anything else that i can do to bleed the pump? I did top off the injector pump with oil, it was pretty empty. 

Please advise and a big thank you in advance.

Regards -TS

I have seen where the tube in the filter tower to the injection pump was plugged with sediment, took compressed air and cleaned it out, this was off the tractor though.

Update -
Noted that Neil originally mentioned that the bleeding procedure was in the manual, looked in the operators manual in the tech library and found the information i was looking for. I bled the injection pump accordingly and started getting fuel at the injector. Start attempt resulted in black smoke and at times a very rough running engine.

Spoke with Jon (big thanks to Jon!!!!) who walked me through checking injection pump and a couple other items. Gut feeling is there is still air in the system. Jon gave some direction on re-bleeding which i will do tomorrow. Need to change the belt on the starting motor.

The good news is, i'm learning a lot in a short period of time. Thanks to all!!

PS: Question: Why is it not recommended practice to not open the injector lines? I'm guessing possible air intrusion?

chance of fuel injection injury. ie high pressure fuel being forced into the body. if you do this dont have the main engine running. and yes it could draw air. but it would bleed itsef of that air. and it can take a couple of goes to bleed these old girls properly so dont run them out of fuel. use quality fuel and keep it that way.

did it clear up? run it for a short period and see if it does. if it doesnt clear up it can be a sign the injectors and or the pump need a rekit. or its out of adjustment or slightly mistimed.
