iveco 75e15 help needed urgently

[philmeakins]

Hi all, sorry if I've posted this is the wrong place. I have an Iveco 75e15 1999 and the inner wheel on the near side (left) has gone flat. I've tried to undo the wheel nuts but they won't budge. I've WD40 them over 2 days now letting them soak. I read that some LH wheel nuts could be the reverse thread which means I'm possibly tightening them rather than undoing them. I can't get my breaker bar in there so I'm using a socket with a short extension which is making it really hard. I just want to be sure I'm turning it the right way to undo and not going to strip the threads.

I know these wheels are very heavy as I have a spare to go on and removing and refitting wheels on these lorries can be a nightmare. Any held advice will be much appreciated.

I don't have any experience specifically with Iveco trucks, so I took a little look online at spares. There are specific studs for front wheels and for rear wheels, but not specifically for left- and right-hand sides, which makes me think that those on the left-hand wheels are not left-hand threaded.

I'm surprised you didn't find the information you needed in the driver's handbook or in the service manual. If you don't have the service or repair manual, you should be able to download one (try here for a start).

Is there enough space to use an impact driver?

Left and right hand threads are a relic of the imperial days.
Any modern vehicle is clockwise to tighten, anti clockwise to undo.
wheel nuts can be very tight if they have been on for a period of time.
Be careful with a socket as that will be the weakest link. A scaffold pole can make a useful breaker bar.

This.

Dad has a huge bar when needing to undo wheel nuts on lorries that are too tight for the air gun. They just need loosening by a few mls and then the normal air gun will be fine.


Other option is to find a local hgv mobile tire fitter. They will have all the tools needed (compresses for the air gun, brraker bar etc) on the van.

Shouldn't be too much to come out and swap wheels.

Thanks for the reply I have spent hours trying to find the answer to this problem, the truck has a double wheel setup and so the wheel nuts are about 6inches from the face of the wheel where one can apply a break bar but we are talking about a socket with extension not best angle for all the force about to be applied. My discovery2 wheel nut spanner fits the. Nuts and fits inside the wheel, using my discovery2 pump jack I’m thinking I could apply the power to try and crack them. Ive wd40 then each day so maybe that’s going to help. I can’t believe these are so solid I regularly grease my cars wheel nuts so in an emergency the wheel can be removed. I’ll post my results shortly.

Cheers again for taking the time.

You need a set up like this..... This is my dad getting a wheel off ready to change brake pads and discs.
He uses this if the gun doenst work and they are too tight. This helps loosen them and then the gun works.

If all else fails, you could try using a blow torch with a very small but very hot flame to heat the nut, or use a nut splitter to remove it... Of course, you'll need to replace the nuts if you break them off, but in any case you might find that the studs are so corroded that they need replacing.

Thanks, yes I know about the use of heat to expand the nut. Cheers for your reply.

No problem.

Dad's been fixing trucks for over 40 years. Truck wheels etc are a bugger to get off at the best of times and you need the right air gun to tighten them back up again after or they will come loose.

Good luck.
