Removing steering shaft on TD5
Hi everyone, it's me again,

I'm trying to remove my steering box to change the gaskets as it's leaking. To start with I have been trying for one week to remove the steering shaft without success. I have the following model :





I'm trying to remove the torx screws but the thread must be rusty as I can't remove them. For one week I have added WD-40 twice a day to hope for change but it did not improve anything. I also tried to heat the top screw with a torch but I was afraid to damage the servo brake above so I did not heat too much and it did not help.

I'm adding picture of my actual shaft if that can help :

What do you think is my best way to remove the shaft ? Do you have any tips ?

I must have the steering box fixed by the 20th December, so any advice that can make the process quicker are more than welcome Smile

Thanks again !

No because I would need to uncouple the shaft to the steering box first Sad

Hi.

I have just replaced my steering box on my 2000 td5. It looks like I have a slightly different shaft to you.

However. I didn't take the shaft off. I undid the pinch bolts holding the shaft on to the splines of the upper steering column and the shaft from the steering box. Not the ones holding the UJ to the shaft.

After applying a little lubricant I found that I could tap the shaft upwards and it came free of the steering box.

To be fair the removal and refitting of the box was harder than I thought due to the weight of it and trying to line everything up.

TOP TIP - mark the shaft and the steering box spline so you will know where to rejoin once its is back in place.

I found this video very helpful -https://www.youtube.com/watch?v=S0JC5ZdU8U0

Thanks for your answer Smile

I'm trying to follow the video you sent, which is very good Smile

Unfortunately I'm not able to remove a single bolt holding the shaft to the splines. I guess they're rusty and I have no clue of how to remove them as lubricant and little heating don't help.

You have no alternative, you have to be able to loosen at least two of the (male) Torx head screws. There is no other was to remove the steering shaft or box.

Even if you were to cut the shaft to remove the box, you'd still have to remove the remains.

Yes that's what I was afraid of.

Any tips that I may not have thought of to manage to unscrew these bolts ?

Other question, do you think the servo brake can handle a lot of heat ? Can I keep on trying to use the torch below it ?

Make sure that you are using the correct socket or wrench and use the longest handle you can. You may be able, by positioning the steering carefully, to use an impact wrench. I'd be wary of heat due to the proximity of the servo, steering box, and other heat-sensitive components.

Plenty of lubricant and the right size socket and extension bar. Wouldn’t use heat. Impact wrench is a good call.

Just a heads up. You really should get some assistance fitting the steering box back in place. It is not easy holding it up with one hand and trying to fit the bolts back.

As suggested above, and if you manage to rotate it slightly, do not keep undoing, but rotate back and forth and undo a little bit more and repeat with the back and forth motion. This lets the lubricant in and the rust out of the threads.

Also ensure that the protruding threads are clean, but I think they are according to one of the pics. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

Once the bolts are loosened, if I remember correctly, the flat section of the shaft doesn't continue to the end, so it is necessary to take the bolts out completely to remove the shaft - I also loosened each side of each of the UJ's as it gave a little more travel to move the shaft away.

^^ Indeed, and this makes it a complete pain if one of the bolts shears off!

WD 40 is not a penetrating oil, just a water dispersant. A proper penetrating oil/ lubricant should help.
Good luck, sounds like a b of a job.

If you don't have any proper penetrating oil (such as Plus-Gas) use diesel fuel, it's surprisingly effective and much better than WD40 as a penetrant.
