4.0 engine out... rear seal? trans mount bolts, and a few other ?'s

[94Reborn]

I'm new to this forum. I was a member at a few other ranger forums but the lack of knowledge and activity on most of the others was disappointing to say the least. There is a lot of knowledge and useful info on this site so I think I'm in the right place.

I'm doing a swap from a 2.3 to a 4.0 from a 93 explorer on my 94 ranger. The 2.3 and trans are already gone. The 4.0 is on a hoist and I'm doing some prep work. I don't think my rear main is leaking. (the flywheel is still bolted up, but I don't see anything other than normal gunk buildup on the bottom of the motor) but I was considering changing it anyway. I actually bought the seal already, 10 bucks from autozone. But I've read conflicting things about installing it. I've heard some say it just taps right in like an axle seal, and I could just use a pipe to tap it in, and I've heard some say you need to build or buy a special tool and it needs to go in beyond flush with the block to a certain degree. If the latter is true, is it even worth doing if its not leaking? The motor has just under 100k on it.

Also, I bought the engine and trans separate, and so I don't have the bolts that mate the trans to the motor. Does anyone know the length and thread pitch of these bolts? Autozone doesnt list them and a quick search came up with nothing. Are they all even the same size and length or are some different lengths due to the starter and whatnot?

Any help or info would be appreciated, thanks in advance!

Not sure on the seal issue, but I would imagine that if the pipe is the right diameter, it will do what the install tool will do. you might be able to rent the tool from autozone too.

as for the bolts, grab them from a junkyard... you will be helping someone else who wants to pull the motor or transmission or giving someone else a reason to curse you if they pull both

I'm going to try the junkyard tomorrow morning, the problem is, most of the 4.0 5 speeds are gone on the trucks in the yard, so the bolts are MIA as well. I called ford and they dont even stock all of them, they stock 2 of the 3 different sizes. The ones they carry would be 60 bucks for 10 of the 12 bolts I need. If I can't find them at the junkyard I guess I'm at the mercy of Ford, and I'll have to try and match up the 2 that they don't carry.

I have to check my bolt pile from when i did my trans swap, the auto trans and manual trans use different length bolts just so you know, also i know it was an odd size because no one local had the size, my job "heavy machinery company" has a very big bolt bin where i found the right bolts.

unfortunately i woudnt have an answer for you until monday, thats IF i can find the box of auto bolts and misc parts i ripped out

You don't have to worry about the bolts, thanks though. I went to the junkyard yesterday and got all 8 bolts plus the two starter bolts and they didnt even charge me for them. But now I have another problem. I don't have the bolts that hold the clutch pressure plate to the flywheel either. I am going to have to try the junkyard again for those unless anybody happens to know that size.
