factory M-H conversion, divorced tc,and I am still learning ..dana?? don't think so it's a groody looking thing in there..cast iron massive piece up there..I'm looking at upgrades that improve her range and safety..

 

Fooey!

There's 18 pounds of difference. But what's more important is that it's out on the end of the transmission where there was no weight at all with the short 3 spd.

Plus, being almost 24 inches farther back, the stress point at the drive shaft connection, greatly increases the risk of chacks in the bell housing at the mounting bolts.

An extra brace isn't going to hurt a thing as long as it's not a hard metal bolt up. There's a rubber transmission mount that is used with these that should be used here as well.

But why take opinions when you can have the facts. These trucks came with an installed overdrive transmission as an option. Either find one (or some one who will send you pictures) or a shop manual that shows the installation and duplicate that - transmission brace or not.

 

OK, so I'm confused as heck.....

I have a T-86 with the same exact flat mounting flange. It is going into my '56.


Do I need a crossmember or not? I don't want to mess my truck up.......

 

My 56 panel has the overdrive hanging off the back just as pictured WITHOUT a cross member. Factory installed with no problems and no cross member.

 

I have spent a lot of time underneath 59 and 60 Ford pickups. I have never seen one with a crossmember and mount for the rear of the transmission. 3 speed, overdrive, or 4 speed. The Ford parts catalog that I have that covers the 57 to 60 trucks does not show anything for a rear mount for the overdrive transmission. The extension housing that you have might have been originally from a car - they used two mounts (on either side) near the center of the engine and one at the end of the transmission extension housing - that is what the mounting surface on yours is probably for. In a car the transmission rear mount supports the weight of the transmission and part of teh weight of the engine. On your truck the factory mounts were one at the front of the engine and two at the bellhousing. Now, if a previous owner cobbled up the car type of mount to replace what Ford put there originally, I do not know...

 

OK, thanks. That's going to make the future installation that much easier.

 

This '59 F-100 is my project that has been in the works for a few years now. I put the overdrive tranny in myself. It originally had the standard 3 speed. The Borg Warner I bought for it, was said to me to come from an older F-100, so I assume from the info you are providing on the mounts, that the BW was itself taken from a car of unknown vintage and was not an original for the F100.
Is there any concern here in terms of serviceability? Is the car type less durable?
Thanks!

 

There were three BW OD units produced - R9, R10, R11 - The changes were done over a period of time with improvements and strength as the units progressed.

As with most topics. I am certain that this one has risen before. The 60 F100 that I bought for parts had this same 3-speed w/ O/D set up and there was not any extra cross member for it beyond the bell housing. The reason that I refer to the previous thread is that someone pointed out at that time that cars did indeed spec out a cross member but trucks did not, thus the confusion!

Sorry to resurrect this devil again, but this project was put on hold for awhile...again.
I see now my 1959 F-100 292 has two engine mounts in the front, and two at the transmission, not the single engine mount mentioned in this thread. They appear factory installed.
So this is further confusing to me.
I am going to have it on the road soon, without the overdrive support unless I hear some further warning, I will give it the "smoke-test" and let you know what goes...or not as the case may be (cracked).
Thanks for all of your input, this is much appreciated.

The mount at the front of the engine does have two isolators where it mounts to the frame. but I have always heard it refered to as the front mount. (really is the front mount assembly)

 

Cool! and thanks!
