engine removal
Okay: This is kind of embarassing for me. I have removed/rebuilt/installed a dozen engines in my life but they have always been paired with automatic transmissions. I understand the relationship of the flexplate to the torque converter to the transmission input shaft perfectly fine. I am now facing pulling the engine from my '75 F100 4x4 project and am kind of cloudy on the process. It has a 4spd manual transmission. I do not want to pull the tranny/bellhousing with the motor or drop it out of the bottom before removing the engine. So... supposing I remove all the bellhousing bolts and start pulling the engine...will it just come out with the flywheel attached leaving the clutch/pressure plate with the tranny? I am just kind of foggy on how what is attached to what in there. Does anyone have a link to a good video or article that details this kind of thing? I pulled a GM 2.8 off of a T5 tranny several years ago for a different project but I don't clearly remember it and wasn't worried about messing the clutch up on that job. Thanks for your help and for laughing at me

The clutch disc and pressure plate will come out with the engine, these are bolted to the flywheel.
The input shaft of the transmission just slides out of the clutch disc. The throwout bearing will also stay with the trans/bell housing.
When you go to pull the engine out I would recommend that you support the bell housing somehow so it doesn't drop down when the engine comes out.

This is what it looks like when it comes out although your truck will probably have a different style pressure plate. The one in the picture is a diaphragm style, you'll probably have a long style, the difference is in the "fingers" that release the clutch disc.

When you go to put things back together you'll need to align the clutch disc with the center of the flywheel. You need to do this so the input shaft of the trans will slide into the clutch disc and then go into the pilot bearing. If the disc isn't lined up it can be a royal pain to get the bell housing to bolt up.
If you look at the picture I posted, in the center of the pressure plate, you can see the special tool they make to line things up. All it is is a plastic version of the transmission's input shaft. These are inexpensive and just about any parts store will have or can get them. They save a ton of work and frustration. The way you use it is, you slide the installation tool through the clutch disc then insert the end of the tool in the pilot bearing in the crankshaft, then you bolt the pressure plate to the flywheel. The installation tool makes sure the disc lines up with the pilot bearing.

Heres you a pic of the alignment tool.
When you bolt the clutch to the flywheel just tighten two bolts across from each other then make sure the tool will slide out freely.. every time I forget to check that I have to completely unbolt the clutch again because it'll pinch the tool!
Good luck

Okay. There is actually one of the alignment tools in the cab of the truck with an empty clutch disc box. Must have a new clutch. (I picked this truck up from a guy I work with. It was his brother's truck and his brother died so details on it are sketchy) So after you bolt the pressure plate down, the clutch disc won't slide around on the flywheel and come un-centered again when you remove the tool?

the engine in the truck was supposed to be completely rebuilt, just never completely re-installed. It was in the truck with no dist. or carb on it and wrapped in a tarp. The valve covers were freshly painted and had new RTV sealer coming out from under them but everything else looked pretty ratty. I pulled the intake and heads and the thing is a total sludge factory.

Correct, once you tighten the pressure plate down, the clutch disc will be clamped in place and won't move.
