Just did a 4eod transmission swap and everything went together perfectly but I went to bolt up the tourq converter to the flexplate but I couldn't get the flexplate to spin with the tool or my hands any thoughts?
Mike, make sure all the accessories are disconnected from the crank (i.e. no alternator, PS pump, vacuum pump, etc.). Also, make sure you remove the GPs before you try to move the engine with a wrench or breaker bar. An engine with 21.5:1 compression is a bear to rotate manually.
I believe there is a spacer in there between it and the crank, you didn't leave it out did you?
That Spacer is Thick, that goes on the Crank, the other thinner spacer goes under the bolt heads outside of the flexplate.. it's the same with the 2 Piece flexplate/flywheel combo also.

Yeah they are .. I don't take the belt off mine but I do pull the plugs

Thanks
with the Tranny bolted up you should have play in the torque converter... IF you don't then either the converter is not correctly installed or you have the wrong Flexplate spacer setup...... not knowing what year and what transmission was in it to begin with don't help much .. when you said Swap.. I wonder Swap from what ?
IF you were able to turn the flexplate before you installed the Tranny then you should still be able to turn it.
You'll never spin the flexplate by hand on an IDI from under the truck. You can hardly turn the engine by hand using a breaker bar on the crank bolt. I also wonder what tool it is you say you were trying to turn the flexplate with?
I would assume he meant the Flywheel tool ....
BUT that would be kinda hard to stick in there with the Tranny attached I would think.. I know there is a bit of room with the access plate removed.
I have a tool that fits in place of the starter for use on the Volvo Penta diesels ... not sure if they make one for the 6.9/7.3 IDI
they call em a "Barring tool" .. as in breaker bar to rotate engine.... one who is industrious could easily make one from an old starter.... take it all apart but keep the reduction drive but lock the bendix out on the shaft so you could rotate either way.
Have had one for years only designed a bit different, they work well. Of course I got stupid and loaned it once to one of our apprentice mechanics to use at home and evidently he had it still attached then engaged the starter and broke it. Rather than buy me a new one he blobbed some weld on it and pretty much ruined it----live and learn.
What are their purpose exactly? In what circumstances would you need too or want to, turn the engine over by the flywheel/flexplate where you wouldn't want/ need to turn it over using the crank bolt? Is it more for productivity purposes, so the mechanic doesn't have to get up from under the vehicle to turn it over and crawl back under, I take it? A shade tree doesn't care much I suppose, up,down,up,down to spin it over to get to the next converter stud, cus how often ya gunna do it, but a guy making a living, looking to shave some time, I can see. Any other purposes?
i have had one for over 40 years. very useful tool for when you need to turn the engine a bit to get torque converted drain lined up, or to turn flywheel to remove converter nuts. instead of climbing out from under truck to put a bar on crank bolt, you just give the flywheel starter ring a nudge and you can see when you turned it enough.
also for setting timing on injection pumps in the case of marine engines ......real handy on the 2 cycle 149's and the Pentas we have down here
using the barring tool that goes in place of the starter gives you Precision Control of where the Crank is.
