Technical Help needed - spare wheel mechanism on Multipla

[starcha]

First of all, hello and thank you in advance!

Three months ago I become a owner of Multipla 2005 JTD. I have problem with spare wheel mechanism. From previous owner I have information that he also expirienced problems because at tire workshop the screwed in mechanism with air tool :bang:, and than problems started.

Did anyone had expirience with repiring this mechanism.

Any suggestion will be welcomed!

Second question:

I want to change front speakers and want to install rear speakers. Which size is neccessary.

Any expirience with using tweeters, installed near windscreen?

Thank you all in advance again, hope to get some help from you!

Hi! We had a problem with our spare wheel mechanism too (2002 Multipla). The cable mechanism was over tightened and we couldn't get the wheel all the way down.... We ended up forcing it and had to replace the mechanism. From memory it was about £80 plus fitting (around an hour I think).

As for the speakers, it was a few years ago when I changed mine, but you can put new tweeters in the dash panel without too much drama, and I think the speakers are 16cm all round, but I'm sure someone more knowledgeable will be along soon!

looks like I've go this job on my multi as well....the spare wheel is stuck up...

I had similar problem, and took apart spare tyre winch ( not easy uncrimping metal, and no way would I have been able to put it back together) - problem was a worm drive component that had been cast in a horrendously crumbly alloy, and had simply fallen apart. New unit was about £110 from Fiat dealer, but at least was easy to fit. Hopefully(?) quality might have improved

same here had mine apart today the worm gearing on the winding drum had been stripped....
it was a bit trickiy getting the mechanisim off with the wheel in place but not too bad if you've got a swan neck 17mm ratchet spanner

I've modified it to make it much simpler and failsafe....but you do need to look under car to get the wheel off now but at least it'll never fail again.....I'm not worried about changing the wheels in all weathers but its no good if you cant get it off at all....

plus after seeing inside the unit I was horrified by the poor design so wont be spending ~£100 on a new one.

Hi Cheapo - what was your fix for the spare wheel winch?

 

[cheapomulti]

I went for the simplest solution possible.

I removed the wheel holder and welded a large bolt in its place

then spray the whole thing black agian and remounted it on the car

Then cut off the wheel holder from its mechanism and drilled a hole in it and opened up the rear with a bolster (to allow the bolt through).

then put the spare wheel back on the car

The silver stuff is antisieze spray.

all I need to get at the spare now is a 19MM spanner......yes Know it meens you have to look under the car to get the wheel off ...but this is the way with 99% of other cars with underslung spares.

I also sealed the hole where the mechanism was accessed from the boot with 2x 1-1/2" washers and a m6 nut & bolt with some underseal for good measure...

plus it keeps my cheapo multipla .... cheap...

Thanks for the (very) detailed instructions! Mine's ok - so far... But if or when it goes, that looks like a sensible and sturdy fix.

And it's always raining when you get a puncture, so might as well start the job by lying on the road!

 

[the frog]

I greased mine the other day and after seeing how rusty the spare has become since last winter I was amazed it came away at all.

I also killed my FIAT jack which collapsed Glad I wasn't underneath the car!)

I followed the general advice-grind off the attachment, then weld a bolt to it, attached as shown in photos, works fine-Paul

 

[cheapomulti]

I ended up welding a couple of 200mm steel rods to the nut securing the spare wheel to the holder as well .... no spanner needed now either and the wheel can be removed just by kneeling at the rear not lying in the road.... looks just like an old style citroen spare wheel holder now simples

Sorry to drag this up after a year...

Had to go rescue my Wife this evening, front right puncture.
Spare release bolt just turned, making grinding noises.
What's the best way to release the spare to get to the mounting?
Drill off the wheel holder plate (the plate at the centre of the wheel), or something else?
Not worried about being able to reuse the standard mechanism, I'll be making something simpler/more reliable to hold a 'proper' wheel and tyre.

Speaking of which, has anyone found a definitive list of wheel sizes (or better yet actually measured theirs)?
Some lists show the Multipla wheel centre as 58mm, others 58.1mm, and the offset as 43mm on one list, and 25-38mm on another?
I don't see how you can even quote a wheel offset as a range, it's a single measurement.

 

[cheapomulti]

I just used ordinary swan neck spanners and dropped the spare and mounting off in one....then once on the bench i ground the fixing for the wire rope off....

most cars have a range of compatiable offsets...
our multi has run on punto wheels for all the time we've had it.

The mounting plate's nuts are hidden under (above) the spare wheel though, so how can you reach them with anything?

Found some wheel lists showing all the specs, and many Fiat models share the same specs (or very close) as the Multipla.
http://www.wheelfitment.eu/omgekeerd.php?steek=4x98&naaf=58.1
The bore is 58.1mm, the boss on the hub measures 58mm.
Still not sure about the offset though, that site claims it's 43mm, but on the wheel itself there's a figure of 31.5, and some lists quote a range of 30-38mm or so, maybe that's what you can fit.

Hello,
I had the same issue (as many have).
The best cure is the cheapest cure too!
Simply unscrew it 4 bolts holding it on and dump the whole mechanism in the tip!
Take the spare along with it too if you want.
The whole thing is actually quite heavy and rubbish, just keep a can a foam instead and enjoy better mpg too!

 

[Zundapp]

Picture this. You get a puncture while doing around 70 mph on the outside lane of a motorway. By the time you come to a halt on the hard shoulder your tyre is pretty well shredded, or at the very least off the bead if you're lucky.

How much is your can of inflating foam worth then?

And will a motoring organisation recover you? It certainly used to be the case that in the event of a puncture, for the AA/RAC to assist you had to have a serviceable spare...

 

[BikeDoc]

The mounting plate's nuts are hidden under (above) the spare wheel though, so how can you reach them with anything?...

Now I've had the chance to get under and have a proper look (and in daylight), I see you can get to the nuts either over the top of the space-saver, or through the holes in the wheel, with a long extension and a U/J or 'wobbly' socket.
I'll get some pics when I do mine.

Problem solved, the spare dropped off as my wife was driving
Saved me the bother, other than jumping on my scooter to go cut the cable.
When I tried to remove it last week the mechanism must have been damaged just enough for it to fail now.

Popped my tyre this morning, came on here to find out how I get my spare tyre off the mechanism!!! Read through all the comments and still struggled,
An elderly man walked past and said the bolt in the boot space needs turning with your wheel brace and then the wheel will fall to the floor...did this after an hour being under the car turning the wheel and it worked!!!!!

Elderly as in 40ish?
