Technical Scratching clutch....

[AnthonyH]

As puntodad says, rotating the shaft is to get the gap in the clip at the top, making it easier to pop off. As per posts 14 & 38 above.

Righto, i was about 80% sure, but its now 100%.

One option might be to remove the big clip from the boot over the inner cv joint. Then you can slide the driveshaft out of the inner joint, leaving the joint in place, if that makes it easier to work on.

Put a plastic bag over each end to protect from grit.

I'll put that on the list of things to try. Sooner or later i'll learn the right technique. It'll even end up being easy to do, but not until I've done a few.

Or you could try this

Or you could try this

This one looks good, i liked the music too lol

My question is...if the circlip isn't at the top and I attempt this will, it do any damage?

It looks like a DIY driveshaft puller that i saw a while ago. I imagine I could try or something similar with some rope.

There are more sophisticated tools that I could buy, but that'd be after i've tried everything else.

I doubt it would do any damage to the shaft. The circlip is quite soft, it might possibly get damaged, but then replace it.
Here's a DIY method that looks like a lot of fun. Used with success on a 169 Panda apparently :

LOL, thats hilarious, those guys have been to a few demolition derbies i reckon!

You do right to take your time.
Removing a driveshaft was the second hardest part of my clutch change (the hardest was removing the flipping battery tray!)
One driveshaft popped off easily, the other almost reduced me to tears.
It's amazing to think just that tiny clip could put up such a fight.

If I get tired of failing with the driveshaft i'll give the battery tray a go then lol Might leave me banging my head on the bonnet buy oh well, it'll get sorted one way or another!

so, battery trap is not even off yet eh ?

lots of stuff to remove for an easy gearbox off and clutch replace job yet to do......

you can remove stuff one item at a time, attend to making that item an easy refit like lubing bolts ready for refit etc., whilst thinking about inner drive joint ( joints ) removal, for gear box off and seal change........

you can encourage the inner drive joint to come out with levers and some intelligent "tapping" of the joint outer........that tapping, not damaging.......

you know of the method for off side drive joint extraction mentioned in the haynes book ?

I'm still going round in circles trying to find the torques head caliper holder casting bolts, that hold it to the hub........4 wanted, 2 per side......

Circles or circus?

Looks like the bolts are in the kit (not as a separate part). Google kit numbers or just "Grande Punto brake caliper bracket bolt E16" or similar query.
https://www.google.com/search?q=fiat+grande+caliper+bracket+bolt+E16 - bolts can be E16 or hex 19 mm. Fine thread for sure.
One of the results is a...FiatForum: https://www.fiatforum.com/threads/f...-for-the-front-brake-caliper-mounting.494988/
Both Google and people on forum will mix bolts in this area (some think it's about small ones, that hold caliper to the slider pins - those are 13 mm hex head and fine M8x1 thread).
Random shop (UK): https://www.fiatworkshop.co.uk/parts/Grande_Punto_Nuts__Bolts_Etc._.shtml - just make sure the pitch is right (1,25 or 1,5 mm).

 

[puntodad19]

Haha, both....

Will have to visit library again as internet phone screen and iffy internet ...


Nerd exact replacement bolts, correct diameter and pitch...1mm, 1.25, 1.5 ?

Suspect bolt will be ,*shanked* rather than thread all the way up to the flange, so shank accurately locates casting in correct position, with no ( or extremely tiny ) possibility of casting "moving" in brake application.

Seems previous owner did away with stainless steel shims....

Thanks for your replies GP, much appreciated.

 

[puntodad19]

Nerd, nah, need...

 

[puntodad19]

Many ways to skin a cat...

I watched the yank vidio, excuse the pun, but would that method work on a Punto inner drive joint, or would it result in a torn gaiter or seperated shaft and inner drive joint...?

The gaiters are pretty tough, new ones being able to be *stretched* by some considerable amount via expanding stretching tool or slide cone.

How well do the gaiter clips hold the gaiter in place ?

Anyways, good marks awarded to the yanks, or are they Canadians ?

I'm going to try to get the driveshaft off tomorrow, i'll try tapping and turning first. Secondly i'll get the driveshaft horizontal with some bricks, then tap and turn.

If the driveshaft won't budge i'll start on the battery tray.

The weather is warming up a little tomorrow which might make things easier.

I'm afraid not.

I'll try this if all else fails.

 

[AnthonyH]

Success. I got the nearside driveshaft disconnected. It wanted to be turned to just the right position and tapped smartly as noted.

I almost took this little victory for the day and went to do something else, but then decided to try to get the driveshaft seal out, but it won't budge and is instead disintegrating! lol

Is there any easy way to get these out or do i continue disintegrating it until its loose?

 

[puntodad19]

Hurrah, success, give your self a real pat on the back. Stuff can be very difficult sometimes, but character building.

Post a better picture of the old seal, and the new seal.......

Don't be tempted to remove those four bolts that hold that cover on........get a manual, even a Haynes one is of some use.

Are you going to remove the gearbox to inspect the clutch ??

You know what is involved with removing the gearbox, and any other "special tools" you may need.....clutch plate aligning tool perhaps, not to mention how engine its self is supported when gearbox is of etc. etc. etc....

Get a Haynes manual at least, good bedtime reading....for armed is for warned.......

 

[puntodad19]

ps....gp, thanks for the heads up about Fiat Workshop, good looking site......lots of info, even if I cannot find the steering columb combo switch yet.

 

[puntodad19]

Anthony,

A lone axle stand, mmmmmmmm

Anyways, the shaft is out. Looks as if you did not remove/disconnect much at all ?!

Prey tell, to help others, what was disconnected/removed please to enable the inner joint to be removed from the gearbox please ?

 

[AnthonyH]

Anthony,

A lone axle stand, mmmmmmmm

I have the car up on two axle stands, one either side. I've thought about getting it up on two either side, but people here said no real need.

Anyways, the shaft is out. Looks as if you did not remove/disconnect much at all ?!

I disconnected the control arm and left the rest in place.

Prey tell, to help others, what was disconnected/removed please to enable the inner joint to be removed from the gearbox please ?

Oh the trick....well on my EVO its this;

1) Leave the driveshaft attached to the hub
2) Turn the brake discs 360 degrees several times
3) You'll notice that the difficulty of turning the brake discs changes from easy to a little harder as you rotate
4) The hard part to rotate corresponds to the circlip gap up - so stop turning when you feel that
5) Use a big screwdriver or similar
6) Rest the screwdriver shaft on the gearbox and place the tip of the screwdriver on the driveshaft
7) Tap the screwdriver smartly with a hammer AND at the same time lever the screwdriver shaft to push the driveshaft out

I can't gurantee this'll work for you, or even me when I try to get the other driveshaft out, but i believe this to be the case.

Hurrah, success, give your self a real pat on the back. Stuff can be very difficult sometimes, but character building.

Thanks.

Righto. I have the Haynes manual and will take a look.

I know in theory but not in practice, i'll have to work that out as i get to it!

 

[AnthonyH]

The driveshaft seal is off. I wanted to see if i'd bought the right one as a replacement, i have.

It took a little persuading, but nothing major.

 

[rmjbn1]

Well done
Must have been very low on oil for a while to get rusty here

Hopefully no lasting damage done to internal bearings.
And I hope that left rear tyre is getting replaced too
