Hi I am in the process of fitting semi air suspension to our Fiat Ducato M/H. The 22mm nuts have been a pain to loosen, (a job undertaken before the unit arrives,) the question is I would like replace all the 22mm nuts that are on the U bolts. Has anyone done this? If so where can I purchase these Please
Many Thanks Vana
 
Any Fiat dealer but I honestly wouldn't botter.
 
Why pay Fiat inflated prices?
Any hardware shop worth their salt will carry a vast selection on nuts, bolts and washers of all kinds
If you can't find a hardware shop try motoring shops, motor factors or small garages.
 
You could use copper slip grease when you put nuts back on makes life easy

When you say 22mm do you mean that you use a 22mm spanner? If so you need to order the thread size 14mm from memory

For example if you have a 6mm Nyloc you will use a 10mm spanner or socket on it. If you ordered 10mm Nylocs you would receive 10mm Nylocs that would need a 17mm spanner!
 
You can get replacement u bolts complete with nuts from most factors, Euro car parts for example. Standard m14 nuts will not fit as these are a Fine thread.

The Drive Rite kits come with new ones as standard.

Just incase you need to know. They are M14x1.5 nuts, and obviously M14 flat washers.

I will check tomorrow on the thread pitch, I thought they were 1mm pitch. BTW they're actually dished washers and two per nut which need to be fitted in the correct orientation.

Typical foreigners, always complicating things.
Much easier when we had UNF, UNC etc. You knew where you were then.
Standard metric thread pitch compared with fine metric thread pitch is like comparing UNC and UNF.

This is the same UNC and UNF that the 'Merkins invented?

Whitworth FTW! "A coarse thread devised and standardised at Manchester in 1841"

Or BSF "Since 1908 this thread, in conjunction with BSW (British Standard Whitworth) has been the mainstay of British Engineering"

UNC... UNF... Pah! Foreign rubbish.

:roflmto:

Then you start restoring vintage British Motorcycles and find you have Cycle Engineers Thread to cope with, that's when you have to to make your own nuts and bolts all good fun. (n)
 
I went for the ‘EasyTOP’ air bags and you don’t need to undo the U bolts, they clamp onto the spring.

Andy Kandy is quite correct, they are M14*1.5 threads.

Standard pitch for 14mm is 2.00 So as Dave said it is metric "fine"

From memory, the same as seat belt fixings? Presumably to make life harder for people to "tinker"

If you want a good game, accidentally tip a box of A4 M5 Stainless Steel metric fine
Nylocs into the tub that holds normal A4 S/S Nylocs Too expensive to thrown the lot away so checked by hand!

I did something very similar when I worked in a Squadron Stores dept. :eek: The difference being that, as a Petty Officer, it wasn't me who sorted through the mess.;);) :LOL::LOL:
 
And for the non technical ones, do we need a little hammer or a 4lb club hammer. Haha

Do you honestly think that I sorted my mess out lol
 
Yeah, but you used to ask for a 5/16th UNF or UNC ... Now you just ask for an M6
Ah but you can use swap Whitworth for UNC up to 9/16ths (may be 1/2" lol)

Off thread a little. A few years ago I was asked by a Lotus main dealer to find and fix an air con leak on a 9 month old Elise. Long story but had to rebuild some pipework and halfway through job realised union thread at one end metric and other end imperial. Lots Of Trouble Usually Serious was never truer.

LOL My first job was working for the Longlife Tyre and Battery Company, and we had to deal with Austin Cars built during the strikes, they would have Lockheed brakes on the bake and Girling Brakes on the front, or the othe way round sometimes just for the fun of it

It happens

I don't know how old your van is, but the more recent vans have oval locknuts factory fitted to the U-bolts. These can create a lot of friction and heat if you try and undo or retighten them too quickly or vigorously, with the end result that the thread on either the nut, bolt or both can be damaged, or the nut welds itself to the bolt. If that is why you have found them a pain to loosen, you ought really to replace the nuts and the U-bolts as they are safety critical items.

My first job was a technical trainee with Dunlop Tyres late 60s onward. Remember a Ford main dealer reporting handling problems on a new Capri definitely faulty tyres. When we arrived to examine it we found 13 in.ch rims nearside and 14inch offside. Over the next few years I became used to all sorts of factory and dealer c#*k ups like this. Lot of bad tyres too.
