I've just bitten the bullet and installed the underchassis spare wheel carrier to our Ducato based Burstner Lyseo TD680G. I've gone for a spare steel wheel as it is slightly lighter but also significantly cheaper than a spare Fiat 16" alloy. The fitting process was reasonably straightforward with the holes already in the chassis exactly where they were meant to be. I did need to open up the holes in the winch assy element as they didn't quite line up with the holes in the chassis but all in all, without the additional work, it would have taken 15 mins tops to fit the carrier (8 bolts). I also found that the process of attaching the spare steel was relatively easy and quick (I know,I won't be saying that when trying to remove it in the dark and wet with a flat tyre on the rear) but I was pleasantly surprised how much room there was under the rear of the van (the waste tank being forward of the rear axle). Now to my question; In the event of a flat I will be looking to attach the removed Fiat alloy to the carrier until I can get to a tyre centre.
The Fiat handbook says to attach the winch to the alloy adaptor plate first and then attach the adaptor plate to the top of the inside of the alloy by screwing three nuts (they come with the adaptor plate) through the front of the alloy into the adaptor plate sitting on top of the inner hub (with me so far?). So unlike the steel spare the winch is not fitted through the central hub on the alloy but sits on top of it. I'm trying to imagine attempting to screw three studs through the front of the alloy into the adaptor plate on the other side of a 30kg tire when the most you could probably angle the wheel at is 45 deg (if you're lucky). Has anyone ever done this and was it easier than it sounds?
