Thread: DSC and flat tyres.

Gary,

If you need a replacement compressor mount (it usually breaks when the compressor is hit) I've got a 2nd hand one for sale.

Cheers,

Gordon

Hi Folks,

After reading this thread, I am more than convinced I made the right decision to carry an air/exhaust bag for lifting. The original jack has never been used since a trial run when the vehicle was new (& I never liked it).

I found the exhaust system and plugging really is dirty work, so nowadays just use the portable compressor and bag, plenty of lift, so it does dual duty when/if required.

As to the main topic, This I made a simple mistake the other day of NOT investigating why the DSC kicked in, then remembered this thread, yup, nail in the left rear, a quick pull, plug and refill and away we went, didn't even have to lift the vehicle apart from move to offroad for a bit of extra clearance.

It was down to 5 psi so probably just saved the tyre.

I would never use a air/exhaust jack for changing a wheel - they are just too dangerous and can fail at any time. They are OK for their use as designed ie helping when bogged but never for changing a wheel.

I think this statement holds true for the LR jack too ... unfortunately

Ok,so who knows of a good replacement jack.

Ridiculous really,a 20K Mitsy express has a better jack,but it probably is not rated to lift the weight of a loaded D3/4.

I finally got around to taking the covers off the air compressor today and as expected the compressor mount has cracked - in fact it is in about 10 pieces.

I am actually surprised how weak the brackets are given the thickness of metal a how it is bolted to the chassis - crap alloy I guess. The full weight of that corner of the car did not get onto the mount - maybe 500kg of static load and I would have that the mount should have carried that.

Despite an large number of creek crossings and very dusty conditions the compressor looked like new - though I am surprised at the amount of padding in the covers - no wonder the compressor gets hot at times.

I would have thought that a fitting that allows airflow and easy cleaning would have been better.

Thanks to Gordon for a replacement bracket.

Cheers

I can now see why there is so much padding around the air compressor - mine is now held up with a rachet strap without the covers on - you can hear it running from 50m away and I didn't realise it runs so much -runs more than it is off - constantly filling the tank as the suspension readjusts itself to different drivinhg conditions - little wonder it wears out.

Initially I found two holes in the rear tyre and had these fixed - they were very small holes that looked like nail holes but there was no foreign body there. I had these repaired but the tyre was still loosing air - going over the tyre with the spray bottle I found another two holes - the same as the first two - very small. All fixed now and holding air - I must have run over sonme wood with nails sticking out. All other tyres are OK.

Of note was that all the holes were in the tread area but not through the tread block. All between the tread blocks where the carcass is thinest.

I'm happy that the bracket only weighs enough to support the compressor as the vehicles are already heavy enough. I wouldn't like to suspend 20kg from it but it holds the compressor quite successfully.
