Pulling The Engine

My 83 F150 has a 300 six cylinder engine. The engine is in need of rebuilding. What needs to be removed to remove the engine. A local machine shop has agreed to rebuild it but the engine must be rtemoved. There are some straight forward things such as removing the hood, disconnecting yjr transmission and radiator. But where do you disconnect the wiring?

disconnect at the motor. take the radiator out so it won't get banged up. if i was you i would take the tranny with the motor. it is easier to put it in than to try to hook it up under the truck.

I disagree with that, especially if it's 4wd.

have it your way it is hard for me to line up the splines on the torque convertor to the tranny. it took us almost 2 hours to get one in on a 4x4 bronco 2. i ut in a 302 and a c6 in an 82 f150 in less than 10 minutes with 2 people and a front end loader. it is easier too me and much other members on this site

The torque convertor stays with the tranny. There are 4 nuts or bolts that hold it to the flexplate. Turn the engine by hand and take each one of them loose, and the engine comes right out. If the convertor happens to slid out a little when you take the engine out, you crawl over in the engine bay and turn the convertor while pushing on it till it engages all the tangs and splines.

I bet you had a real mess when the torque convertor came off with the tranny oil going everywhere.

Forgive my newbie question, but I, too, plan on pulling the engine (302) out of my 86 Bronco to get it rebuilt or replaced, and I've never done anything like that before. My question is, how do I turn the engine by hand? Do I grab hold of the flexplate and turn it in order to get to those 4 bolts? Or is there some other way to turn the engine by hand?

For what it's worth, I plan to also rebuild the tranny (AOD). I realize the original question in this thread was about pulling the engine. I don't mean to hijack this thread by asking this 2nd question, but it seems appropriate given the content, or at least I hope it does. Anyway, my second question is would it be best in my case to pull the whole engine/tranny combo out, or would it be best to pull them out separately? If it's best to pull them out together as a combo, do you or anyone else have any tips, warnings or advice on doing this? I have a tranny jack adapter, and I hope to be able to borrow a buddy's engine hoist. Anything else I might need?

I hope my questions don't amount to a thread hi-jack. If so, I'll gladly post them in a new thread.

Thanks for any info.

Just another tip, the engine will be easier to turn over by hand with the spark plugs removed...no compression to fight.

Thanks for the great tip on removing the spark plugs, Dan. I'll be sure to remember that when I start removing everything.

Also, as I was studying my Haynes Manual, I came across a "caution" that warned against rotating the engine backwards when turning it by means of a socket on the crankshaft pulley. My newbie question is, then, which way is backwards? Do I turn the crankshaft pulley clockwise if I'm facing the front of the truck?

Thanks for any extra insight.
