I was going nuts after work trying to remove the 4 speed from my tonner. I have removed countless engines and sometimes the combo but tonight I was confounded by the 'rear engine support' at the crossmember under the tranny. The rear of trans has a flange with two holes. Two large studs protrude upward through the crossmember and this flange with castelated nuts on top. These take a 15/16" wrench. Engine still attached to trans at bellhousing. I want to leave the engine in and swap transmissions. I have supported engine with jack and jackstands. My desire is to remove the two big studs so I can slide the trans back without lifting it up over the studs. The studs actually seem to be bolts as they have a head below. I decided the plate under them with six 3/8" bolts needed to come off. That was a filthy chore digging out the bolt heads. Now under that is a big rubber block insulator but still these bolts (studs?) wont unscrew. If I have to jack the engine up 2" to clear them I will have to remove the exhaust and seems it will e a chore getting the other trans in place with these two bolts sticking up.Do they come out? 7/8" wrench for the heads. Am I not wrenching hard enough or are they bonded to the rubber blocks? I have tried driving them downward with nuts flush using a large brass drift and hammer but they don't budge. Signed, frustrated in Olga. PS I searched green bible for pictures of the parts to no avail and Van Pelt site as well.

 

So these mounts are connected to the transmission or the bell housing? It's been a while since I was under a flatty truck and the only thing I have to look at is a 35 frame with the 4 speed still in it. For some reason I was thinking those mounts were on the bell housing like a Y block.

 

i remember fighting that ! and not really understanding what was going on. a few weeks ago when getting stuff cleaned ,i looked at the transmission support. and didn,t remember exactly how it went together. i kinda skip it and went on with other stuff,thinking i will figure it out when time comes. so i remember taking it apart 2 years ago,and that it was a fight! and that it was just stuck together! i can take pictures of what i got.

 

Old -vs- new. The big bolts go through the outside to the tranny. The inside ones are bolted to the crossmember, if memory serves. Nothing is captive here just hard to get to.

I removed those outside bolts first, then unbolted the rubber mount.

Lots of room left when its out.

 

 

We are getting closer.... newold, the tonner seems different from the half ton. TC's figure 16 shows what mine looks like. It's flat across and has those six 3/8" bolts. TC do you have any more text about remove-replace the REAR engine support? The one in fig 16?Looks like my stuck bolts are indeed threaded bolts, just stuck real hard in the tough old rubber. I think once I'm done with work I will wail on those bolts with a sledge hammer and a piece of 2" bronze propeller shaft. With some nuts on top of course.

 

And here I was thinking they were the same. Well, they were nice pictures...

 

Gary - this is what you're fighting. Same piece as on my 48-52s. Your original is 01T 5089-A and is 11.5" long. Ford substituted the later 8T 5089 for it which is 8.5" long. The name of it is Insulator Assy, Engine Rear Support to Cross Member. I've pulled several to replace and seem to refer to them more correctly as a PITA. Your use of the BFH is the correct tool. If you are intending to replace it if it gets damaged I believe they are NLA, but they do show up on eBay occasionally. Stu

 

GB, The two 5/8 fine thread bolts thru the insulator with the castle nuts on top are probably rusted into the insulator. The insulator also has a tendency of rusting in the crossmember making it hard to remove. If you have the plate off of the bottom, you can use a wrecking bar and pry the insulator with the bolts out of the bottom of the crossmember.

Thank you all! My son and I are headed out to do battle with those bolts!

 

Hoping for good news with the after-action report.

 

i checked out mine ,and theres a steel sleeve in the rubber transmission support. the big bolts are rusted to the sleeve. i had forgot that my support stayed stuck in the crossmember. BFH is the tool penetrating fluid will help!

 

Well it took all of you to make this happen! PB Blaster, BFH and my 23 year old son to help me wrestle that heavy tranny out. We even had time to get the new one in and bolted up. Here he is at 9 years old. We have had quite a few mechanical adventures together over the years. Thanks for the help!

 

I read this with significant smugness because I was able to remove the two bolts without any trouble whatsoever. Then, I read further through the posts until I found myself asking, "What rubber insulator"?

I will have one when I begin reassembly soon.
