I’ve never replaced a phone screen before, but since there’s a wide range of spares at reasonable prices available out there, I decided to take on this repair for a friend. The screens on these and other smart phones are fragile. They are made of finely machined glass, made to extremely high tolerances and therefore susceptible to damage from knocks and scrapes. At this point usually, I might whinge on about how manufacturers do this deliberately to some extent, to bolster built-in obsolescence, but on this occasion, the break was due to the owner falling off his bike (off-road) and the phone hitting the deck, while in his pocket. I’m amazed the damage wasn’t worse. No hospital treatment for the owner on this occasion, just bruising and a dent to his pride.
The repair kit for such damage came in at a reasonable £8.99 and the eBay vendor promises to have the kit within a couple of days. I’m sure you’ll all be waiting with baited breath to know how the repair goes. I will of course keep you all updated.
The repair kit has arrived and there are lots of components in the box. After watching a few (very good) YouTube videos on the S4, I think I’ll need a clear evening to repair the phone…
From a chap who’s repaired his Athlet using my video.
Just a thank you. I went looking for a solution to the intermittent cut-out on my Bosch Athlet and found your solution. It took all of about 2 minutes once I’d found a suitable length screw and works perfectly. Like it was designed that way.
In your video you thought maybe the handle was removable to allow the attachment of some accessory. It isn’t. It’s just a way of making the box smaller for shipping.
Which means if Bosch put the hole in, and supplied a screw, it would be a much better product. (But of course, then they could sell it as no assembly required:)
But seriously, thank you. I love the Athlet, but that bloody intermittent cutting-out was really beginning to bug me. If I’m ever in Worthing I’ll buy you a pint.
A frustrated customer brought this ‘stationary’ mobile golf trolley in to the workshop recently. He’d replaced the control unit along with the hand controller. The battery was also new, but the trolley wouldn’t respond to the controls.
A systematic test of the wiring revealed no problems and power was getting to the motor OK. However, with the unit switched on, every now and then, the motor would make a noise, a faint hum.
This indicated that the motor, a Lemac 65178-101, was trying to do something. A few searches online revealed that the Hillbilly Compact is no longer made and parts, including the motor, are hard to obtain for reasonable money, this is a shame as the unit is only just over 10 years old.
The customer likes this particular model due to its lightweight and compact folding ability. New ones are several hundred pounds and usually heavier.
Since the rest of this trolley is serviceable, it seemed sensible to have a go at a repair. With the motor removed, the cause of the fault became clear. The commutator was heavily blackened and scored and one of the brushes had burned away, probably due to the heavy weight the trolley had lugged around a golf course.
Being realistic about spend on parts, I thought it would be a good idea to order some replacement brushes from Amazon. These brushes will come from Hong Kong via Sourcingmap (an excellent source of hard to get parts) and I will let you all know how I get on with the repair. The motor’s back-plate is available online for just over £15 plus P&P, but I like to repair the problem, rather than waste components that still work.
More to come… I expect you can’t wait.

Now, some of you will remember that I’ve written about a similar issue before, but I think it’s worth covering again as often, complete replacement items need to be purchased, which can be costly.
This Bissell Powerlifter Pet vacuum cleaner had snapped a belt, due to an obstruction in the roller/ beater area and while the casing was open to replace the belt, I removed the beater to see how smoothly it turned. It was noisy.
Seemingly, Bissell will only supply a complete unit for around £30, with shipping, so given the overall value of the machine, it seemed sensible to have a look at the noisy component on the bench. The bearing housings, located at each end of the roller, come out easily and with some careful manipulation, each bearing can be removed.
On this unit, both bearings were dirty and dry. Now, I could have replaced them with a generic bearing, but in the spirit of thrift, I decided to clean the bearing races with brake cleaner and then repack with high-melt-point grease. When reassembled to the roller/ beater, it ran very smoothly and was much quieter, once re-fitted to the vacuum cleaner. Job done.
I quite like the idea of this vacuum cleaner in that it’s lightweight, easy to use, highly portable and easy to maintain. All things that make a great product.
The particular vacuum cleaner came in to the workshop, just outside of its warranty period and had been looked after well. However, it had developed a nasty intermittent cutting-out problem when in use. I also noticed that the charger’s flex had also cracked near the wall plug, making it dangerous while charging.
First things first and it was off with the rollers and filters to clean any obstructions that might make a device like this overheat. Nothing obvious there, but all items cleaned and washed as a precaution to allow the roller to move freely and the vacuum to breathe easily.
Closer inspection of the handle area revealed a weakness in the design which had meant that the quick-release mechanism had caused an electrical connection to degrade, causing the cutting out.
The only remedy was to address the handle’s weak point with a mechanical fix and make good the electrical contact.
I hope Bosch take note and make an improvement in this area on an otherwise nicely engineered item.
I also did a small repair to the damaged flex on the charger.
Cost of a new vacuum cleaner, circa £250. Cost of screw… less than 50p (without my time of course!)
These chargers often lead a hard life, working in dusty, hot and noisy conditions, so I guess many of these fail in time.
This Bosch unit is fairly common among Bosch DIY drill sets and this one had died catastrophically. With the power applied, this one refused to give the slightest charge to a drill battery, once plugged in.
After some basic testing, I decided to change four components which would have caused the other to fail in a ‘domino effect’. The cost of the replacement parts was just shy of £10, but definitely worth saving since second-hand units seemed to be changing hands for £40 on eBay, with their condition largely unknown. The parts (two resistors, MOSFET transistor and diode/ transistor) were readily available online.
I recorded a short video to help others who might have a similar problem with theirs…
