This asthmatic car tyre pump came in to the workshop with little going for it. The owner had been very close to throwing it away when he came across my website.
This AirMan pump is designed to be plugged in to a car’s cigarette lighter socket and provide quick and convenient car tyre inflation. This one was dead.
On first inspection, the fuse was OK, the switch seemed to work and all connections seemed sound, when tested with a multi-meter.
Off with the cover…
When the motor was removed from the cam driving the piston, the bit that drives the pump, it spun freely when power was applied, using a battery in the workshop.
Seemingly, the centre spindle was protruding far beyond it’s specified reach, causing the pump connection rod to it it during rotation. Why? To be frank, I wasn’t sure. I can only surmise that the vibration and heat had caused the flywheel/ toothed drive to slide outside of specification.
There appeared to be room for a small washer to take up the excess space, so I fitted one I had lying around.
The washer, once fitted, allowed the flywheel/ toothed drive to sit ‘square’ in-line with the pump.
Once resembled, the pump ran freely and was ready to inflate, once more.
Cost of a new pump, circa £20. Cost of the washer, circa 5p.
A slight departure from my usual ramblings about white goods and other domestic appliances in this entry. Outside of The Workshop, I’m a keen petrol head who loves to tinker with cars and motorbikes and my own car was suffering from a recent bout of coolant incontinence.
Like me, most owners of these cars dread anything like this happening as it usually means big money.
The leak only happened when the car cooled after it was was run up to temperature and was evident in the area under the oil filter housing. Luckily, the leak wasn’t serious and was repairable with a 10mm spanner, washing-up bowl and 4000 grit sandpaper.
Here’s a little video which I hope will help other Boxtser owners.
This Dyson presented with a pretty terminal case of ‘no go’. The owner had run this relatively new machine in to the ground with little maintenance so it was little wonder what happened next.
Whilst in use, the machine spectacularly went bang and tripped the main fuse board of the house. The noise and following smell was quite something I was told.
The owner had nearly rushed out and bought a new machine and was budgeting between £300 and £400 for a replacement.
I was glad I could help since I was fairly certain I knew what the problem was without seeing it. After giving the cable, switches and casing a visual inspection, it was time to delve deeper. The filters were in poor condition and the general smell of it indicated that overheating had been an issue, probably leading to premature wear on the motor.
With the motor out, the true extent of the damage became apparent. Both motor bushes had worn away to nothing and part of the brush holder had broken up inside the motor, probably while it was running, causing the noise.
I suspect that the owner had ignored the warning signs of burning smells and occasional cutting out (as the thermal overload circuitry performed its fail-safe role).
Being only a few years old, the owner had a couple of options; either replacing the faulty part with a genuine Dyson replacement (a very reasonable £40) or pattern motor kit with filter pack for under £25. The owner chose the latter on the basis of the machine’s age and the fact that both filters in the machine were also ruined.
The job took an hour, including testing before the machine was back performing its cleaning duties once more.
A note to all vacuum cleaner owners (that don’t take bags): Keep your filters cleaned every couple of months or so. Your machine will last much longer if you do.
