Removing the gearbox backward, it's stuck

Is it the axle assembly or the transmission that won't budge?

o,k maybe I didn't explain properly
I,m looking to pull the rear axle /prop shaft assembly backwards to leave the gearbox attached to the engine with 2 bellhousing bolts holding the two together,then remove the box and lift up into the cab. its the axle end that wont move .....will have another try the weekend ,thanks .

correct ,unbolted all the necessary bits but pulling the axle backwards wont budge an inch. will have to leave it till the weekend and check everything again .

Are you using a spring spteader and is the spring clear of the rear cross member.If you lower the diff too far it the torque tube will jam in the hole through the centre of the X brace.Cheers

[JSeery]

Same question as GEOFFNZ really, are you trying to pull it back with the torque tube at an angel to the transmission output or is it inline with it?

Ok got ya.

I'd put some more bolts back in the gearbox. Just to be safe while struggling with the axle. Speedo turtle not getting snagged up? Shox all out of the way? Clamshell undone and out of the way? The torque tube passes over the central crossmember so will get snagged up if the rear end is lowered too far.

To be honest on my 40 I did it the other way round. I left the axle in place and pulled the engine and box as a unit. In my case though, it was the engine I wanted to work on so the situation was different.

I can see the point about using a spring spreader to keep the rear spring as flat as possible, it would keep down the angle that the axle needs to be lowered to to clear the crossmember and tank.

Good points being made.

Post #1 " dropped the axle etc but with two of us pulling and tugging from the rear it won't move"

I assume this means that the banjo is down on the ground (or close to it) with the driveline still attached to the trans. I almost made this same mistake a couple weeks ago. You need to jack up the banjo till the spring just clears the cross member and the rear diff will just roll right back.

Thanks guys, I will try to get it as level as poss,I,v got a spring spreader,might be worth a try. I think maybe a mistake I made was myself and my sone doing this job late afternoon after a morning of hard building work so was knackered when we started it ,trying again Saturday early and fresh,thanks again.

Can you post some pictures here of where this project stands at the moment......pictures that show the rear area of the transmission, begining of torque tube bell with two piece collar removed, opening of tunnel area where torque tube bell must come through, how the rear of the engine is being held up. Some pictures taken from behind the car showing how the banjo rear and spring are positioned now relative to rear cross member as it's ready to come back and out from under the car, and any other pictures that you feel might help us understand what could be happening, or maybe not happening.

A friend (non v8)came over today and we got it nice and straight and eventually it slid out yeeees, the problem now is the gearbox slides back but not far enough,the left shoulder of the gearbox housing is against the gearbox cradle part of the chassis ,the universal joint is fixed to the gearbox drive shaft ,I was expecting it to move with the prop shaft ,I,m looking to undo the six bolts that hold the rear gearbox support but the U.J won't slide off the drive shaft ,I don't want to give it too much force in case I,m doing it wrong ,how can I get the U J off the drive shaft ? Thanks

We call it gearbox ,you call it transmision......in case it gets confusing again .

[JM 35 Sedan]

Well, I guess we don't need any pictures now. The UJ is held to the transmission splined output shaft with a heavy washer and bolt right up through its center.

9/16" socket on a 3/8 drive extension, up the middle of the UJ. But (admittedly I've never done this) I don't think the rear carrier has to come off. People above have mentioned the gearbox needs to be rotated somewhat to get it out.

The two alternatives are.... raise the rear of the engine, with trans attached, so that rear trans mount clears the X member enough to come back and disengage from engine, or remove the rear trans mount and this will allow the trans to come back and disengage enough to come up and out.

This is basically the same thing I said in post #11.

[37coop]

Never knew about the centre bolt up the U J ,many thanks guys ....good ol Ford Barn,
always reliable,couldn't have got this far in the hobby without it.
Ready to start restoration of my 37zephyr coupe ,I,v had it sitting here for 28 years ...that's gonna need some advice from you guys...oh yes.

See post# 10 also

on the 39 & 40 fords it is some times nessary to losen the bolts near the tunnel & jack or pry the floor up to clear the torque tube bell as the bell on the torque tube hits it
