number one rule> take the top off the trans, it will come out and go in so much easier and you can fill it with oil also. my HF trans jack is the 2000 lb model and it goes up far enough and will roll out from under the truck also, well worth the $200.

put the transfer in neutral and the inter shaft will turn, no need to roll truck.

don't see why you would need to change the adjustment much unless the clutch was really worn out and even then nowhere near an inch. have someone hold the clutch pedal down and see if you can turn inter shaft to make sure it is all working.

Yeah, hindsight I wish I had bought the bigger Jack back when I bought this one.
I didn't think the Transfer case had Neutral ???
Yeah the adjustment thing is scaring me. Another member asked if I checked the finger hieght as per TM. I didn't realize that. Do the pressure pates normally need adjusting ? I have put many clutches in, including double disk class 8 and aside from the old Macks that used shims I have never had to adjust a pressure plate.

My method of choice when I am doing one myself is the 4x4 thru the front window and back of the cab and a 1-ton chain hoist. Makes it so much easier to wiggle an jiggle the transmission into place. I have dropped enough transmissions that I can get one out in under an hour.

Ok, the plot thickens. Spoke to Illinois auto truck. The pressure plate is NOT user adjustable. It is factory set for the correct application. He double checked the part number on the plate and said it is correct. He is checking the disc as I type this. Fortunately I took really good pics of all the clutch parts before installing for future identification.
The TM prodcedure outlined for adjusting the plate in the TM does not apply fo this plate as it requires special wrenches so there is another
Issue. Can we get a suicide smiley added ?

Well we determined the clutch is the correct one. I guess I see how it works when I get it fired up. It does not hit the hub.

Does anyone know which TM covers priming the motor with oil ?

Well, with a little help from God, I will have it running today.
I do have a concern though about what to do with the flame heater. Is it worth re installing it ? I see the PO of the motor I bought had it plugged. Opinions ? I think if I reconnect it I will install a shutoff on the fuel line to it. I have to find it in the TM's but it looks like the same basic operation as a Garage space heater with a fuel mist and igniter ??
I read this but my concern was more towards a malfunction of the flame heater and spraying raw fuel into the motor while it's running.

I took mine off, not because I had problems with it, but because others did. I never really had trouble starting mine in the cold, so I felt it wasn't needed. I can always open the pass window and give it a quick shot of starting fluid if I need to.

Well it fired right up...no oil pressure. Nothing. I put a mech gauge on it. Nothing. I reprimed it 2 more 2x. Pumped almost 2 gals of oil through it. Nothing. Pulled the oil filter off and cranked it over. Nothing. Re checked the pics I posted in this thread, the tubes are installed correctly. Either the oil pump is bad or there is something broken in the motor that is letting oil dump back to the pan.
Either way I'm done. I will be posting parts for sale after fourth of july weekend. I am cutting this piece of crap up like I should have .
Remember the lesson here, if it does not run when you look at it..then the truck is worth only what scrap value is.
I dumped over 2,000$ into the motor swap plus another 2600$ for the truck. I'll be lucky if I get half that back in parts. Don't buy a non running truck. Period.

Sorry, just read more.

Double check the oil pump installation, If you need a pump, I'll send you one, just pay for shipping.

It is probably something simple yet irritating. Don't give up yet. Remember that it takes nearly 20 seconds running at 6-700 rpm to get oil pressure when there is already oil in the system. Spinning over via the starter motor only nets around 300 rpm. I would crank it and let it run on its own power for a minute or a minute and a half and see. If no pressure then, pull the pan, check your work again, and post a want ad for a used good oil pump from a parts motor. It could also possibly be the pressure regulator on the passenger side of the motor has failed or stuck. Don't give up after doing 95% of the work.
edit: I missed that you did let it run. How long did you run it?

I let it run 6x at 30 second intervals. After I had reprimed it with almost a gallon of oil I let it go a full minute. Nothing. Yes it has oil. Abut 6 gals in it now with the reprime. I pulled the regulator off. It looks fine and the one piston was loose and the other under tension. I compared it to the one of the old motor and was exactly the same and the plungers moved freely.
I have not been able to get ahold of the guy who sold it to me to see if he swapped the oil pump with the LDS although I was told they are the same anyway. I took very good pictures(in this thread) of the oil pickup install so I would not second guess myself later. I even ordered and waited for new gaskets for the pickup tubes because I like to do stuff right the first and hate doing things twice. Unless the oil pump is either defective or the wrong one, the only other possibility is something let go in the motor and it's dumping the oil pressure somewhere. It's 7:45pm and I am so pissed off I am going outside to rip the pan back off right now. I am not happy. At all.

Thank you. I'm gonna clean out the one off the junk motor. I know it's good because despite the damage the motor had awsome oil pressure. Just wanna flush it out good in case there are any shavings in it.
