Technical How replace o-ring cam shaft seal

[thesmithsUK]

Hi all,

Can anyone point me to a guide on how to replace the o-ring cam shaft seal on my 2005 Panda 4x4?

This is the part: https://www.eurocarcare.net/gaskets-seals/ecc14463980-o-ring-cam-shaft-seal.html

There isn’t really a simple guide because it’s not just an external O-ring swap.
On the Panda (169), the camshaft seal/O-ring sits behind the cam pulley, so you’ll need to remove the timing belt and pulley to access it. It’s basically almost the same level of work as doing a timing belt job.
If you’re going in there, it’s worth considering doing the rocker gasket plus o-rings and the timing belt at the same time if it hasn’t been done recently.
Just make sure the timing is properly locked and set on reassembly.

The o ring is on the gearbox side

Just unbolt the plate and replace the o ring

Fitting the timing belt with crank and cam locked will cause the timing to be one tooth retarded when the locks are removed. White mark the cam pulley and you will see that the cam has to be set one tooth "out". Tensioning the belt then pulls it correctly into line.

The original poster has asked about this

Not this

To fit the fist one that @thesmithsUK posted you don't touch the belt, timing or anything like that

It's just on a plate you remove change the seal and screw back

As long as they posted the correct part it's simple

Cam timing was mentioned therefore my comment is appropriate. Sorry for not attaching the quote.

Thanks, koalar - yes, that's what i meant. Sounds a whole lot easier!

And I found an excellent 'how-to' video:

That is one great video. Thank you for sharing.
I thought you need to get the camshaft down in order to get to the oring, but obviously you don't. Just the coil packs support will do. And you are there. So, very easy job, actually.
I never got why they made the cam cover end open there, with the oring. Was there something connected before, that would be turned by the camshaft? I think there must have been. And it took them a while to modify it. Many engines now have that cover end closed, no oring needed.

I found that o-ring cracked on mine when changing the thermostat
and was the cause of a small oil leak
I cycled off to the local hardware store to get a matching rubber o-ring - I measured it at 36mm inner diameter.

Easy job (with the help of that video!). Old one removed; new one fitted; all back together in an hour. That's one weep sorted; rocker cover gasket next...!

I did mine a few years ago, I had the right dia but was slightly thinner than the one I took off so I tried fitting two. Still nice and dry.
