I am responsible for replacing the clutch and its components in a 1990 F150 I6 5 speed work truck. I have done this operation on a tractor before, but need some pointers on how to dissmantle the u-joints, driveshaft,the shifter, and anything else leading up to the clutch work. Thanks for any help.

 

There are several different driveshaft configurations available. You maybe be able to unbolt the driveshaft from the companion flange in the rear, or you may be able to unbolt the u-bolts that hold the u-joint to the flange, or you may have to press out a u-joint to get the shaft out.

Once that's done, you remove the shifter. There are four screws holding the boot down. Remove them and the three torq screws holding the shifter assembly. Put the tranny in first before you start, and then just lift the shifter up.

Unbolt the tranny from the engine (4 bolts), remove the starter, and unbolt the tranny from the cross member. If you are on a lift and have a tranny jack, drop the tranny completely after disconnecting the speedo cable and reverse lights. Otherwise, you can slide it back far enough to get in there. The rear of the engine will need to be supported too, otherwise it will make sliding the two apart harder than it needs to be.

Then just unbolt the pressure plate from the flywheel, unbolt the flywheel, get it resurfaced, install a new pilot bearing, replace the flywheel, clutch disc, and pressure plate. I would also recommend replacing the slave cylinder with a quality part. They like to leak, and as you know by this point, are a lot of work to replace. Replace it now and you won't have to worry about it.

Everything else goes back together the way it came apart.

 

well all that you said makes sense. I have the press type u joints , how do I get them out?

 

i just did a engine and trans in a 87 f150 i did it with my 8 year old son advice i can give you is have an extra hand a little older than 8 it was tuff and even though he was eight i couldnt have done it without him he worked the jack while i put it in i was lucky it lined right up first time so have someone with muscle mine was a t18 4 speed and it was heavy my arms hurt for 3 days and you may need a puller for the pilot bearing mine was a bear to get out

 

If it's the same as my dad's truck, you can unbolt the driveshaft from the axle in the rear and then it just slides out of the back of the transmission. I don't think you should have to press any u-joints out under the truck.

 

I had to press mine out. If you don't have the type of driveshaft that you can unbolt from the rear axle, then you're going to have to rent a ball-joint/u-joint press from autozone. That's really the only way to get them out.

I scored a Mac ball joint press on ebay a while ago for $80 - but not everyone's that lucky.

 

the 5 speed transmission has the bellhousing cast on it .you dont have much room to get at the bolts or to move the transmssion back to clear the pressure plate.I pull the engine when I change a clutch.just easyer for me.

 

I never knew there were driveshafts that had to have the u-joints pressed out to get it out of the vehicle. Interesting.

 

I have never seen one either

 

Yep, it's a 91 2wd supercab shortbed. I was pretty suprised too, usually the little u-bolts are there.

 

what rear end do they use?

 

It's a ford 8.8"

 

so your saying I have to get a special pressing tool? how much does this cost to rent?

 

Free from autozone, as much as I hate to plug them.

 

when i did mine it had a carry bearing on it i dropped the carry bearing and drive shaft bent enough to slide out of tranny
