Spare Tyre Info?

[mosquitocoils]

Hey guys, small thing but I'm just curious what the rules are about my spare tyre.

It's in there, decent tread, pumped up etc, but the long screw that holds it down won't go into the hole very well, it doesn't screw all the way in so it doesn't exactly hold the spare tyre down. I've got some wood and bits of rubber wedged in there to keep it still but this is obviously not 'allowed', is it?

How can I fix the threaded hole in the floor of the boot without cutting it out and welding a new one in, or how can I secure my spare tyre more effectively? Any ideas?

mine sits safely in the garage

so what's the actual problem? the bolt is the original bolt yeah? so its long enough?

so problem is thread where its suppose to screw into is stuffed?

can you get a nut on it maybe?

[mosquitocoils]

Yeah it's exactly what you said. Original bolt, the threaded hole is stuffed.

[ZENNON]

well if you don't want to try and fix the thread, longer bolt with nut might be an option..

might have problem to get the nut in.... Just get a bigger bolt and retread the hole.. My 2C

[ZENNON]

yeah that would be a better option

how on earth did you stuff the thread in the first place? tried to do it up to 130Nm? lol

is the thread all rusty and dirty? clean both threads with inox or CRC if so, and a wire brush (or old tooth brush) on the bolt thread to ensure no shit caught up..

if the thread itself is buggered, your gonna have to try re-thread it or weld something in there

[mosquitocoils]

Hahaha thanks for the replies all.

I didn't stuff it up, that's how it came when I bought the car. I've (and a couple of other's as well) given the bolt a good going-over with CRC and a heavy wire brush so it's clean and smooth as... it's definately the thread in the hole.

I know there's a tool(s) that you can put down it to rethread it, but I'm not sure of the skill needed or the price etc etc. I think Repco had a set but it was way too expensive in my opinion, as I only needed one.

yeah you need a 'tap'.. i got plenty @ work.. problem is that once you retap it your removing more material and will not be secure..

no need for a spare tyre as far as rego/rwc goes... garage is the place for it..

Hey mosquitocoils. Go to bunnings or supercheap, they should have some cheap tap sets. Repco is good for hard to find stuff but they can be expensive for the basics.

Anyway try get 2 taps (if u don't get a kit), one the same size as the bolt and then one a size or 2 bigger. Make sure its the same thread type(some threads are obviously courser or finer than others).

Next carefully run the tap thats the size of the bolt through. You might want to use a little bit of oil on it to make it run through smoother (you can buy proper stuff for it but a bit of engine oil or the likes will work fine). When turning the tap through try go slowly, 1 trurn in, half turn out, then 1 turn in and half turn out untill your all the way through. Doing this just cleans the hole out as u go so you don't jam.

Ok if that works then ur happy. If not then you will have to decide if ur gona drill out the hole (only use a drill big enough to get rid of the thread), or if ur gona just run a bigger tap through. I'd go for option 1 cause it will end up cleaner.

So drill out the hole, just getting rid of the thread (doen't mater if u get rid of a bit more but don't get rid of much, go in stages if need be ie. slowly increase the drill size till you'r happy). Then using a tap cut ur thread as above. You might wana make sure you can get a bolt for the size you'r tapping first so that don't have a newly taped hole but no bolt that will fit.

Taps go up in drill sizes ie. the drill size you use to drill the hole is the tap size u will be using.

Hope this helps. A bit lengthy I know but should be all you need to know.

Have fun.
