manual 3 speed trans rear seal edit: need help

[thebannister8]

i need to change the rear trans seal and there's nothing in the manual on it and i've not done it on f100's before...seems pretty straight forward....any tips/tricks....thanks...

well...not so straight forward....i have a 3 speed 3.03 trans....i asked the parts people for a rear trans seal....and i got the pictured seal below.....my questions are...is the seal that is at the end of the tail peice the fluid seal or is it just a dust seal.....is the real seal where the the tail peice mounts to the square box of the trans...does the seal i have look familiar....i've never done this so tips are welcome....thanks

p.s. the whole trans shown is what mine looks like....it's from this site

its probably as easy as removing the yoke poping the old one out and poping the new one in. tap it in evenly when it goes back in. or use a socket the same size as the outer part of the seal so it doesnt mash the edges and not seat properly.

The round seal you have in the pic is both a dust and fluid seal....... the seal you asked about at the square part of the trans is just a gasket between the tailshaft housing and the main gearbox.

the seal i have on my bench there has a lip to it that could only be mounted from inside the tail piece...that sounds odd to me ... is that the deal

That's a slip yoke style seal. The long rubber cone (aka dust seal / wipe) would go out and the metal would drive in from the outside up to the flange on the seal.

I can't say if it's the same diameters on yours to the slip yoke or not, but on my old rambler they were the same seal save for the dust seal. None of the parts stores listed anything but the slip yoke type seal so I had to cut the dust shield off to use it on my fixed yoke.

I'd suggest just taking it back to the parts store and telling them that they gave you a seal for a slip yoke trans and yours is a fixed yoke. They'll likely have it, and if not you can call around to your other local stores till ya find someone who does and buy it with the refund from yours.

it is a slip yoke type of seal. the yellow part goes inside and the black rubber part goes outside. you have the wrong seal i think. i have seen guys cut that rubber off of the outside and use a seal anyway. i am unsure how it turned out though.

thanks for the information.......perhaps might anyone know the stock# of the seal....i went to my local ford dealer and said 67 f100 and the guy said " our computers only go back to 1980 " ....i asked if they had microfish and he said no.. .....any idea what to torque the big nut to that holds on the fixed yoke..thanks

note...the diagram pictured shows #7052 .... it appears to be the rear seal....i wonder if this is the part number

[FreakysFords]

If anyone would know the number, it would be this guy. He could probably also find the torque for you.

Call 256-835-1000 and ask for Greg Rutherford in parts. He is THE man when it comes to storing such info off the top of his head.

those diagrams would only give the main part number. the whole part number would be longer and include that number in the middles of the whole part number
