Richard,
First thing make sure there is fuel to the injector pump. You may need to
loosen the injector inlet line to bleed any air. Then, on most diesels, you
loosen the fitting that connects the fuel supply line to the fuel injector.
You then need to go through a number of cranking attemps with the starter
until you see fuel coming from the loose connections. Keep in mind not to
crank the engine more then 20 to 30 seconds at a time without about a 5
minute rest. Not doing so could reck your starter. You will most likey
need to have a battery charger on hand to charge the battery during the 5
minute rest.
If you have your owners manual for the tractor you should find a section on
how to do the above for your model.
Good luck,
Eric D
It is necessary to bleed the injectors. There should be instructions for
this in the owner's manual, but the general procedure is to first open a
plug on the injector pump and crank the engine until fuel comes out, then
close that and repeat the procedure with each of the banjo bolts on the
fuel injectors. Hard to say if it will be obvious which plug on the
injector pump should be opened.

Hey!! My advice is free -- take it for what it's worth!

My owners manual for an 870 says the fuel system is self bleeding.
Same engine maker just slightly larger. You could make sure that fuel
is in both fuel filters. Funny thing is step 5 of fuel filter change
says bleed the fuel system. See service/ as required. Go to that
section and it says that fuel system is self bleeding.

Oh, yeah. A good 40amp battery charger was always near at hand too

Anywhooo, The line from the filter to the injector assembly show plenty of
fuel flowing (messy). After lots of cleaning, I made sure that the injectors
had fuel. Little flow but fuel none the less. After cranking like was stated
before not to heat-up and damage my little bitty starter, it coughed a few
times. Fired off once and waalaa!
Thanks yall!
Shes got me back there still clearing that ditch (gully). Thanks yall, I'll
remember that it was yalls fault I am back at work! :)

I believe the 650 is a 3 cylinder 21HP engine, but that's not
important.
First off, file the tank with fresh #2. Remove the right side engine
cover (right side while sitting in the seat), lift hood, then 2 twist
locks and set it aside. Find the fuel filter (glass jar kind of thing)
on the rear lower area of the engine block. Twist the plastic retaining
nut to 'loosen' the filter (breaking the air pressure). Now turn the
key to ON (which will cause the electric fuel pump to run). DO NOT TRY
TO START IT YET!
Once you see fuel squirting out of the filter, turn the key off.
Tighten the retaining nut. Now turn the key to ON again, waiting for
the glow plug light to go off. Start cranking, while moving the
throttle lever back and forth.
It should start within 10 seconds or so. Happens all the time on my 655
(same engine as your but full hydro trans).

(to send e-mail, drop the "HatesSpam" and change the "feet" to "foot".
Removong the fuel filter and filling it with fuel before reinstalling
it will usually cut the crank time enough to get it started. Or, most
diesels have a schrader valve near the fuel filter which, when
depressed, will bleed off air.
It should take ~30 seconds for the air to work out thru the injectors.

First I believe they all are different, my Ford 3500
Fill tank,
bleed through bleed screw top of filter,
loosen injector pump screw and bleed
loosen injectors
throttle wide open crank engine till air free fuel is comming out
injectors
tighten injectors and start.
ps I followed this proceedure for change out of dirty fuel filter and
worked just fine. E d ke6bnl
For future reference, there are two different diesel injector schemes.
One uses only one pipe to each injector, and the full amount of fuel flows
through that tube. The second scheme uses one pipe per injector plus a
common pipe feeding all the injectors (or all on one side of a V-style
engine). In this second scheme the smaller per-injector pipes simply
carry enough fuel to actuate valves in the injectors, and the bulk of the
fuel flows through the common tube. All tubes flow back to the injector
pump because it's needed to generate the high pressure required for
injection.
