Re: Leaky Gearbox

Cut it off and get another one sounds like the only way to go, it does look well past it.

Good luck today, I hope it all goes well.

Re: Leaky Gearbox

Yep Horible time of the year to mess with motors unless you have a heated garage, should have thought a bit more when buying the house

Anyway as said good luck with it, it's always handy someone else doing the job before you need to

Re: Leaky Gearbox

Thanks, Alan & Doc.

Not much achieved today as the garage was very very cold even with the fan heater on. I thought at one point I as going to expire altogether.

Cut the clutch cable off with a junior hacksaw (essential part of any fiat owners toolkit along with various sets of molegrips, and evidently I need a blowtorch as well...)

Whilst I'm at it, I've also decided to replace the radiator, so I've taken off the air intake trunking at the front of the engine bay. Guess what - all the bolt heads sheared cleanly off upon application of any torque. Nice.

So, I now need to work out how to get the remains of the bolts out. Either that or buy an air induction kit like Doc's got...

Alan- hope you are not planning to follow in my footsteps any time soon. I've got until March-ish to get this finished. Slow and steady wins the race...

Happy Christmas
Doog.

Re: Leaky Gearbox

To continue my master class in very slow Fiat mechanics, tonight I undid the LH driveshaft - 6 bolts 6mm Allen key. As I undid them oil/thin-grease started to seep out of the joint between CV joint and gearbox flange. I've now moved the driveshaft out of the way and tied it up but in order to do this, I had to compress the CV boot which forced grease out of a little hole in the gearbox end of the CV joint (does that make sense??)

This is the end of the CV joint on the driveshaft with hole from whence the grease came circled in red (sorry - poor photo editing with MSPaint):

This is the gearbox output shaft flange covered in grease from the CV joint:

Do I now need to rebuild the CV joint/boot? Or can I just take the boot off and fill with grease? Is there supposed to be a seal to stop grease coming out of the little hole? Or should the be a gasket between CV joint and g/box output flange? This would appear to be the source of the original leak, anyway.

All advice appreciated as always.

Doog.

Re: Leaky Gearbox

Hi, you can pull off the CV boot and replace the CV grease. CV grease did not come out of mine when I removed the drive shaft on my B. I removed the brass colour back plate thats in the first pic with a pair of ring pliers.(see pic) once removed you can see the condition of the CV joint bearings.



I dont remember the CV join having any oil seal inside but I could be wrong. (sorry)

Re: Leaky Gearbox

I'm struggling to understand this to be honest and can't think why there would be a hole in that flange? there are seals on the inner cv joint as per pics below which seems remarkably over engineered?

Just to make me understand a little better is the gearbox output stubs sealed so the gearbox oil doesn't come out when the driveshaft is removed?

If you need any part No's let me know.

Re: Leaky Gearbox

Starting to make sense again seems like the dif is sealled from the drive shaft so that hole must be to assist lubricate the other part ?

While the drive shaft is off it seems a good time to replace the rubber boots.

Re: Leaky Gearbox

Thanks, Alan and Doc. Excellent info as always.

Doc - you say that no grease came out of the hole in the brass coloured plate on the g/box end of the CV joint. I reckon this is correct - no grease should be coming out of the hole.
Also, how did you get the brass plate off with the circlip pliers? did you just use them to lever it off? I can't see anywhere where I could use circlip pliers on it.

Alan - thanks for the drawings and info. As you say I should probably replace the inner boot whilst I'm at it. Definitely no hole in the gearbox flange to let oil out. I think the leak I have been seeing is CV grease coming out of the hole in the end of the CV joint and seeping out of the joint between CV and gearbox flanges. I reckon I need to either replace the brass plate or a seal inside the CV.

Doc - Did you get a new brass plate and some oil seals with the CV repair kit from Fiat?

Getting there slowly...

Cheers
Doog.

Re: Leaky Gearbox

The circlip will be used to remove item 9 the inner CV roller joint if the cap is No 13 in the first pic it should just pop off but may be held in place by the gasket fusing to the surface and will be held in place when re bolted to the output flange on the box.

Once one Joint is off both CV boots can be replaced by sliding them both from the one end.

Re: Leaky Gearbox

Thanks, Alan. Looks like the cap is 13 in the pictures, so presumably 14 is the circlip holding 9 onto the driveshaft. 3 (in two places) looks like an o-ring or gasket and that is what I think I need to replace.

Can I tap 13 off the end of the CV with a soft faced mallet? What do you reckon?

Doogal.

Re: Leaky Gearbox

Hi,
To get the (13) brass cap off, place the tool I told you about above on the black part (9)just behind the cap, when you spread the pliers the ends of the pliers will hit the lip of the brass cap and the other lip (6) on the other side of the CV joint giving you a spreading force, thus pushing off the brass cap without damaging it. Do this 3 or 4 times around the cap and it will come off.
(The brass cap is only pushed on)

The pliers must be the close grip spread tip type.

Re: Leaky Gearbox

Doogal could you take a side pic of the driveshaft when your next out just for curiosity and the other side as well when you get to it, but only if you are doing that side. Mine is well tucked in in the garage.

Re: Leaky Gearbox

Thanks, Doc. Will try that tonight.

In an earlier photo in this thread it looked like you had your driveshaft out on the bench. Did you take it out of the car to work on the CV joint? If so, can you give me any advice on getting it out at the hub end?

Alan - photos to follow tonight when I get home.

I owe you both (and Dangil as well) a pint or 2 when I get to the end of this little "project".

Doog.
