Panda (Classic) SEAT Marbella (Mk1 Panda replica).

Re: SEAT Marbella (Mk1 Panda replica)

Hmmm. Some inspired driving perhaps? It's a good effort to break the diff. Shows how much torque you are developing. It's running too well!

Rebuilt box with straight gears from a specialist has got to be well over £1000 these days. Have you got a price? Doesn't seem worth it to me, unless this is going to be a really long term relationship.

As far as a new differential goes, the box is a unique type I believe as no car other than the 127 got the Brazil OHCs. I don't have my technical manual anymore and my memory of my Y10 Turbo that never was is fading, so I can't remember what actual gearbox it has now. I reckon it will be a normal Panda/Y10 box with a special bellhousing? In which case a diff will be easy to find, and a cheap fix. Got any pictures or do you know?

If Damon hasn't got NOS competition for me, I'll be staying at home on Halloween!

Well I just overtook a truck which didnt take too long so I wasnt pushing it. But I guess I have been using its performance too much up till then. :eek:

I have not got the time to look into the box right now, got to get a working car quick! When I find out some more about what box it has and see what has exactly happened too the diff I'll post up some pics and let you know. I do know that the diff was much wider than the marbella's original one so unless they changed it for the fire engined pandas it will be a special one for the Y10 / Y10 turbo :(

This might be quite an expensive fix, but I've enjoyed the project so far so its all a good learning experience. A bit sad but I am not atall suprised really :eek:

Re: SEAT Marbella (Mk1 Panda replica)

Well slowly getting the gearbox in a state where I can remove it!! But just havent got enough hours these days before it gets dark (and too cold to think!!). I did have a feel around inside the diff though (sounds like a line from a carry on film - feeling around inside the "difference" lol) and it seems there is part of a bevel gear rattling around inside!! :eek: I can't wait to take it all out and see how badly this has failed lol!!
Maybe have the gearbox out tomorrow, and some pics of the devastation :eek:

Re: SEAT Marbella (Mk1 Panda replica)

Its just a FIRE gearbox with a different bellhousing. I believe the ratios or the final drive may be a little different but it shouldnt be hard to get it mobile again.

This is what I thought. If you want it working quickly Si, just swap bellhousing onto a Panda box. Would require some disassembly either way though I would have thought.
 
Re: SEAT Marbella (Mk1 Panda replica)

The marbellas gearbox is completely different to this one, and thats the only 2wd box i have unfortunately not even sure the bell housings would swap. Also, perhaps I am being neive here but would they not have made a stronger box / internals to cope with the torque? I think the marbella box would just explode in a shower of gears!!
Anyway, I'll sort something out. I've found someone with a Y10 GTie box so far (thanks to trevor - Yintegrale on that one).

Re: SEAT Marbella (Mk1 Panda replica)

The idea that a stronger box is needed does make sense. The truth will out shortly I suppose. Perhaps the standard Marbella box is a different type to the Panda as well?

If Trevor can remember it all, he would still be the man to ask! I'll keep quiet until there is some facts on the table!

I think the marbella did have a different one to pandas in general. It only has a single rod change on it too which I thought was a bit odd! I'll know a bit more when I get the gearbox off though. It was too wet to do it today unfortunately. Not to mention dark by the time i got back :(

I also want to check I have got the engine mounted correctly too, just a hunch but if the engine is sitting incorrectly atall the driveshafts may be interferring at extreme suspension positions. I dont want to go through another diff and there is no harm in making sure!

I'll finish it soon right? :bang:

Re: SEAT Marbella (Mk1 Panda replica)

Well finally took the gearbox out today, and as I suspected one of the gears had snapped in half. It fell out as I dragged the gearbox out from under the car!:eek:....

Gearbox all cleaned iup and ready for inspection tomorrow. Should be interesting, but I am slightly nervous I have to say. More pictures to follow!

Re: SEAT Marbella (Mk1 Panda replica)

Crazy! That gear looks like reverse or more likely the reverse idler. That doesn't bode well for the general state of the inside of the gearbox I have to say. Proper job.

I think its the central pinion gear in the diff. I didnt get round to taking it apart to see for sure today :rolleyes: but the gear seems to be missing from one side of the pinion chaft from external examination.

Re: SEAT Marbella (Mk1 Panda replica)

Well gearbox all inspected, and as suspected it was the diff satelite gear....

You can see some damage marks to the shaft where the satelite gear used to be...

It broke into 3 pieces!!!!! I am still not sure why it failed though but to be safe I will concider uprating the diff. Just not sure from where, a little birdy told me that quaife dont do a diff for this box :(

Re: SEAT Marbella (Mk1 Panda replica)

So it did fail where you thought. Does make a lot more sense than what I said, but I didn't know you were fishing in the diff area! Can you get some pics of the gearbox, so we can perhaps identify any common parts?

I'll get some pictures tomorrow when there's some good light. I expect that its all pretty panda'ish in there I think its just the marbellas one thats a bit of an oddball...

Re: SEAT Marbella (Mk1 Panda replica)

What a stroke of luck!! I found / remembered I did actually have a panda 2wd box!! Identical as far as I can see to the Y10 internals and the diff looks very similar. Unfotunately this gearbox was obviously left outside and had sand inside :eek: I can't use the diff really as all the roller bearings are gritted up (and I dont have the tool to pull them off but I can swap the pinion and pinion gears round to get the gearbox working again....

Is it worth putting it all back together though with what are probably insufficiently strong gears? I think there's a chance it will go on for many more miles as these gears would have been under relatively little stress from a panda engine. So may be far off fatiguing. Might be worth doing that rather than finding out its breaking for another reason and ruining a more expensive diff :eek:

Also, the pinion shaft and gears are slightly different:

Panda (TOP) has swirl grooves at each end and Y10 Turbo (BOTTOM) has flats:

The gears are also ver slightly different in design (Panda LEFT / Y10 RIGHT):
DSCI2538.JPG


I've got to use the new pinion shaft as the y10 one has damage from the breakage and also need one of the gears too so either way I am forced into it. Just curious as to why these differences exist. Anyone have any ideas?

Finally, as I mentioned last night the marbella gearbox is totally different to the panda and the photo below shows the marbella one attached to its original engine still and the panda one beside it (RIGHT). Bell housing is the same of course, but after that its all new :p

Re: SEAT Marbella (Mk1 Panda replica)

So it is a Panda box. That's good I suppose. I would just re-assemble as you can with what you have. If the box is changing OK otherwise, then sod it. It's not exactly awful to have to take the gearbox off again if this happens in the future? There are much worse jobs. Presume you kept engine in the car?

Yeah, wiggled the gearbox loose leaving the engine in. There wasnt much room for it to drop out the bottom though! barely got past the suspension arms.

I agree though, I can take it out again if it should fail. I think I'll put it together with the good parts I have and see how it goes.
