Gearbox oil leak- from drivers driveshaft seal,,.

[Budgie]

DCi has sprung a leak,

Have cleaned it all up, and it's leaking from the drivers driveshaft output seal.

Pics:

Seal in more detail on a spare box I have:

Anyone know if it's as simple as pull the old seal out and replace? Seal available seperately?

Will give Agency a call on Tuesday and find out if nobody knows.

I've never had to do one on a Clio but usually it's an item that available seperately and cheaply. Nice and easy to change usually just be careful and don't bend it

 

[Budgie]

Fingers crossed.

Luckily, it's pissing out at the minute, so will have to source one pretty sharpish.

Never seen one leak there on a Clio either. Freak of a car.

 

[Scrooge]

I done s**t loads on my old E box I had on the punto and a few pug ones, both times only the main dealer managed to supple decent ones.

 

[Mr R.]

Just looks like a standard lip seal mate.

Should have the size on the seal?

 

[Budgie]

Had a look online, and seems the seal set can be had for a tenner,

Result.

Will order one, and hope it's right.

Yeah, fingers crossed it's as simple as picking the old seal out with a pick and push fitting the new one in.

 

[AlexW]

Hella easy to get it out. Pop new one in squarely.

Had to fit a new gearbox to a customers dcI as this exact same thing had happened and they didn't realise so carried on driving.

Pretty easy to replace just ensure its in square.

 

[Budgie]

Jackpot.

Cheers chaps! That's what I wanted to hear!

Anyone know if the bearing behind this seal is easy enough to replace as looking at diologys its a tapered bearing so im thinking it should be an easy replacement.

You need the proper socket to undo the nut and there's a shim that the bearing sits on. You'll never get the bearing race out and you have to re-shim the bearing to get the correct preload on the bearing.
To do it properly it's a box out and full strip down.
If you've got noisy bearings it'll be the main diff bearing that's usually the culprit.

i got told the other day you can't put too much preload on the bearing...:nomouth:

 

[J.beazley]

Cheers for the helpful information, so all in all my oil seal has gone but I do have movement on the shaft so expected the bearing to be at fault.
Seeing as it's going to be a rebuild to sort I may as well buy a recon 182 box and bolt that in.

 

[bloke]

where is the movement on the shaft?

 

[J.beazley]

It's literally up and down only by a few mm but it's still moving enough to let oil past the inner seal.

 

[bloke]

'only a few mm' means it's knackered, must be noisy as hell unless you mean the joint itself not just the shaft on the diff?

 

[J.beazley]

Shaft on the diff doesnt move so guess its the joint to the driveshaft. No noise from the gearbox doesnt whine or crunch or anything just leaking oil from the shaft seal.
I had the car on the ramp late last night in the garage looking for where the oil is leaking from.

That's nothing. I've got one in at the minute that's already been rebuilt by a legendary specialist - and he didn't bother putting the shim in to preload the input shaft (twin taper bearing box on the shafts). What a flat out pen15.

tell me about it, i always wondered why one car was always hard to push and when you started it up it would lurch forwards sometimes, blew three casings. turns out the crown wheel was about 2mm higher than the pinion and was mashing the washer up on to 1st gear!!!
