Hi All,

After installing new drive shaft seals, should the 'plastic' outter ring that helps you insert the shafts without damaging the seals be removed?

The Haynes manual suggests that they should be.. but I just wanted to see what others think or have done.

My current seals are only 1 month old and leaking. 1/2 of me thinks it's due to poor installation, the other 1/2 of me thinks that the plastic rings have cut into the seal as these somewhat rotor with the shaft.

Also.. what process should I follow to ensure that THIS TIME they don't leak....

Thanks
Justin

p.s here is a pic of them.

i would remove them as they would cut into the shaft
regarding seals and shafts the shaft bieng the harder material will always get a groove and wear and as the plastic seal protector sits proud of the seal surface it would also cut into the shaft over time
when you pull your shaft out make sure there isn't a seal groove in it
there probably will be
my advice would be to see if you can plce the seal in a slightly different position in the housing or get a quick sleeve put on the shaft
the extreme is to weld up the groove and machine it back
rule of thumb is that the harder material in contact with a softer material will always wear more then the softer
i realise that this sounds backwards but it is an engineering fact :D
 
I've never had problems leaving them in.
As suggested try repositioning them on the shaft and even more importantly, make sure there's not excessive wear in the bearings. If that's there, they'll never seal.

Pls tell me that isn't a pic of a drive shaft seal. Or two... I bought a non-pug one for $5 after pug gave me a price of $40. Mine is a CONTECO brand, and says some stuff about citroen. Is all black and looks kind of like a cap but with a hole in the middle. I got it from the place near auto paris... the renault specialists. PLS HELP! I was goinnng to do it this w/e.

Rambo, did you mean "Speedy Sleeve"?

My post from the other thread on the same issue:

A couple of generic tips for seal replacement is firstly to get some 1200 grit carborundum paper (wet or dry - grey stuff) and polish up the surface where the seal lips seat on the shaft flange/housing. Secondly, IF POSSIBLE, mounting the seal a millimetre or so below the surface of the seal housing will cause the seal lip to sit on a different part of the sealing surface. As it is, there's usually a groove worn and the profile of the new seal doesn't match this groove - result, leaks. Just make sure the design of the housing allows this, and the seal wont rub on the bearing etc. behind.

I used after market seals on my 306 found the same problem with teh peugeot ones not sealing properly, and my aftermarket ones didnt have the plastic ring around them.

Just make sure your innner and outside diameter is correct and you shouldnt have a problem

yeah stuey
quick sleeve
speedy sleeve
they are made from stainless generally and you use heat to expand them enough to slip over the shaft and let cool
use shaft as per normal

Hi Guys,

Well. I watched a pro do them today. A & L drive shafts in belmore.

1. Basicly remove the old one CAREFULLY so as not to damage the housing.
2. Using 1200 paper, sand back any nicks in the housing
3. buff up the shaft
4. soak the seals in gearbox oil.. (dip in, hold for a few sec's then out)
5. Seat them carefully
6. Insert shaft.

Most of this is in the haynes, but the soaking of the shaft is different.

Hey hang on a minute....did he soak the seals or the shaft?? :confused: :confused: and just to put everybody's mind at ease, did he leave the plastic inserts in or not? whistle

HI Alan,

Soaked the seals... but as for the plastic insert?? they are still on. I'm going to call AUto France to see what they say... just to be sure

The plastic seals are supposed to stay on. Every FWD pug I have changed the driveshafts on, sometimes for the first time since they were made have had the plastic seals on.
The bit that the Haynes refers to, is slightly different - The seals used to come with a plastic applicator type of thing (it's hard to describe) which had to be removed. They dont come with these anymore.
You can tell if you have the seal in straight, as when its installed with the driveshaft inserted through it, the plastic ring should rotate freely. If not, its not straight and will leak. This I know from experience!!

Hey Justin, pardon the ignorance but when we took my driveshafts out of the 205 (they've been in and out about 10 times now and finally they seem to be sorted :) ) I don't remember seeing these driveshaft seals.

Where do they go/sit in relation to driveshaft/hub/gearbox?

Cheers
