12h-t freshen up and swap (1 Viewer)

[niffa]

Thats what the manual shutoff is

 

[AussieHJCruza]

Aha, I see now, sorry! You can manually actuate the intake shutter! There you go, I learnt something today!

 

[dawery]

my 1hdt needs about 12.8 to crank over so that should be pretty similar. How fat is the cable from pos terminal to starter? mine is really fat cause those oil burners do need all them amps to get going

 

[mcguirejohnson]

No spacer between crank and FW.

Wait a bit with pulling the tranny.

Later or tomorrow I can get some 2H /12ht starter teeth measurements, and you can compare it to that your new unit. There has been some differences, maybe @beno or @OrangeFJ40 knows teeth count or other intel.

Edit: and I'm certain cracking fuel lines would not lower compression. For that, you'll have to pull injectors, I would wait on that too.
Would be easy if you had glow plugs [emoji14]

The engine isn't seized? Jack up a rear and put in 4th, turn wheel. Or get a wrench on the crank bolt to verify.
(I think the nut is 46mm)

The starter I have in there has the same teeth count as the original 24V unit that came with the motor, but that would be great if you could double check!

Yes I definitely do not want to pull the injectors or transmission again.

The motor is not seized, I have rolled it in gear and the motor turned on the stand so I am good there...

Since flywheel is stock, starter is new and running in bench mode, but not in flywheel mode, I still believe there is some issue there, when all electrical checks out.
If you wanna play, put some clay on the flywheel and mount the starter.
Give it one try, and take out the starter.
That will show you if it has engaged enough on the flywheel.

Another thing, was this a 24v rewound to 12v starter?
Could be that the solenoid24v isn't strong enough at 12v. Ok in the bench, because no resistance, but not against flywheel!?!
It would be like putting 6v on a 12v starter, right. It would spin on the bench, but not have any force.

Just a thought!

The first thing I am going to do today is try and jump the starter with some jumper cables as if I were starting it on the stand. That should determine whether or not my positive cable is pushing the required voltage. The cable is pretty thick, it was the one that my gas motor had though, so it could be something that I have overlooked.

That is a good idea with the clay, I will have to check that out.

I do not know about the starter being re-wound. I do have my old 24V starter that I can test and see if it does the same as my current unit.

 

[TLC Norway]

Ok, sorry for mixing that up, probably from another thread about the rewound. Anyway, if you have that 24v starter, compare them, like how long is the throw.

 

[CenTXFJ60]

The 12 volt starter we are using is a 24 that was rewound. By checking the throw, is there generally a difference between a 12 & 24? I like the clay idea as well. And McGuire is going to try a thicker cable in the meantime. Thanks for the suggestions as you can tell we are truly stumped on this one.

When the starter was reworked, are you sure that the solenoid was reworked from 24V to 12V? If it was not, it might not generate enough force to pull the starter drive all the way into engagement with the flywheel or close the contacts to start the motor spinning.

My $0.02

Can't guarantee that it was. I talked to the guy we got the starter from and he wondered the same thing. Is there a way to test this without taking it into a shop?

 

[elkaholic]

Now you went and pushed me
In over my head

I have no idea if there is a way to tell short of talking to the shop that did the work ...

 

[TLC Norway]

Any old part number on the starter?

 

[mcguirejohnson]

ITS ALIVE!!!!

 

[niffa]

Happy days! What was the issue?

 

[mcguirejohnson]

Very happy! And I guess the 12v starter was a bad unit, hooked up the 24v one with 2 batteries and jumped the terminals and she fired right up!

 

[niffa]

Nice

 

[CenTXFJ60]

Nice work son. Can't wait to get home tomorrow to check it out.

Kicked over nicely too, music to your ears, and now you know you put the motor back together correctly as well, Double bonus

Yes it sounds really mean compared to the ol 2f. The first start up was a bit smokey but it smoothed out rather quick. Yes definitely a double bonus, I was starting to have my doubts...
