Stopping ih 624

[Axell]

Hi!

Today I got a ih mccormick 624 with loader. Problem is that it can't start. It started fine last night when it was loaded on a truck.
The starter turnes i bit and then dies. Maybe a good thing because I dont know how to stop the engine. The key switch has been removed. So how is it stopped? Which one is the kill switch?

Hi, your IH 624 should have a German D-206 Diesel engine with a Bosh VA injection pump on the front left of the engine like the one in the photo below.

It has been many years since I operated a 624 but the key switch ON only allowed the generator to charge and START to engage the Starter.
IIRC the STOP/COLD-STart/RUN cable knob was on the lower left of dash and OUT was STOP and IN was RUN and COLD-Start was partially out.
With reference to the photo:
1) rod with the Purple highlight is the Throttle rod, shown in the Idle position.
2) Cable with the Green highlight is the STOP-Cold START-RUN cable or possibly a rod, I think in your photo it may be just above the clutch pedal.
STOP-COLD Start-RUN lever positions with to photo:
RED line is STOP position with plunger fully depressed, BLUE line with lever just touching end of plunger with plunger extended is the COLD START position
GREEN line with the lever touching the front adjusting screw is the RUN position, if the lever does not touch the front adjusting screw like the one in the photo the tractor will lack power.

I think I have found the stop and it is attached to something like the one you show.

That is the correct cable and it is in the RUN position.

(quoted from post at 11:42:15 08/26/21) That is the correct cable and it is in the RUN position.

Many thanks for your help on this. So nice to know that. Hope it will start. Just wonder why the batt was drained during the night. If something is wrong in the electrical circuit. But perhaps it has just decided to quit now.

The key switch has to be in the OFF position when the tractor is not running or it will be sending power to the voltage regulator if equipped with generator or to the alternator.

Hi again.

From I got it the plunger was hard to press. So much that the cable broke.
I gave it some wd40 in hope it would get softer.
I just cant believe it is supposed to be that hard. I have seen a couple of videoes were an old tractor is shut off like mine and it doesnt look hard.
Is your stop plunger tough to push in?
