240 General: Driveshafts and Motor/Gearbox mounts

[Bob 1967]

Just started a bit of work today.
I (eventually) removed the rear portion of driveshaft.
Tried spanners and a electric whirly gun I got from Lidaldis on the
14mm bolts ,ended up resorting to cutting with angle grinder as neither of the aforementioned were any success .:
I'll have a go at the front section tomorrow.
I fear it'll be the same .
The bolts (4) seem to be 11mm with 13mm nuts ,gave them a good soaking with WD but don't hold much hope of them loosening. Access for grinder is restricted by the gearbox mount .
New spiders and engine /gearbox mounts ordered from Skandix.
In hindsight should have ordered new bolts , doh !

Why were you removing the drive shafts? Does something need replacing there?

DP90 or other release oil seems to be a bit better than WD.

The engine and gearbox mountings are fairly easy to change. I found the Scandix parts quite expensive so I got generic engine mounts (the same ones for hundreds of cars and vans) that cost around a fiver each and work really well.

Good fortune,

Alan

Hi Alan ..
"Why were you removing the drive shafts? Does something need replacing there?"

Yep , there were noises .after removal it was found the spider at diff end were well past their sell by date. So replacing all seemed to be a matter of course.
The Centre bearing and mount will also be replaced .
It also gives me a chance to clean, treat and respray the shafts,
as well as anything else underneath including the exhaust from the manifold to the centre box.

"DP90 or other release oil seems to be a bit better than WD."

The problem is the nuts /bolts are so badly corroded ,so I don't think any penetration fluid is going to make much difference.
I think I'm the only person to see under the car in over 10 years !!
Stay safe
Bob.

Good morn Bob,

Understood, that is a pretty sensible approach then.

WD will be better than nothing, and might just help.

Underneath an ancient 240 car can sometimes seem a lonely place when one finds one thing wrong... then another... and another...

Good fortune,

Alan

I found the prop shaft bolts tough to get out when I dropped the 'box on mine recently. Ended up with the car on ramps, and a jack under the end of a ratchet to crack them off.

When you refit the rubber 'spider' (technically a 'guibo' or 'flex disc'), make sure you orientate the metal centre finder correctly, and also the guibo so that the drive is against the fatter portion, or you will get some horrific vibrations. DAMHIKT......

Update : front shaft removed.
came off much easier than expected .
Cleaned the around recesses for the Circlips (Spider bearing) and will leave soaking to ease removal later .
Time to remove Centre bearing.

Well done Bob,

If you had a spare minute perhaps you would post a few photos and words in case this is useful to someone else with the same problem?

It sounds like you have this beast well under control.

Hi ,there is no rubber ("Cush drive" ) on mine it's a flange to flange fitment.
1040 type drive/prop shaft.
Also not sure how to add pics to posts ,had a photobucket
(https://s271.photobucket.com/user/bo...ilder/profile/ ) account years ago but now they want money and my email from the account is no longer in existence so recovery is not possible .

Hi Bob,
Yes, you need a hosting site to post photos. Photobucket has started charging, but there are other free services. I use imgur.com - it works fine and is easy to set up an account.

Cleaned all circlip /bearing recesses with wire brush bit in a drill

This will make it easier to remove clip and bearing caps.

You can also see my gasket on the gearbox sump, made from cork sheet.
I just laid the pan on a sheet of cork gasket and drew around it .
I put white board marker on the mating face and used it to print the gasket on the sheet.
