Andy’s boys
turned up on Friday and set to rebuilding the generator. There were three Sri Lankan Mechanics
supervised by Jako ‘Slim’ Nieuwenhuizen, a damn great Boer who told me never to
call him ‘Slim’ so naturally he’s called Slim.
No slight is intended. It is just
the same as calling a vertically challenged individual ‘Lofty’, a particularly
skinny bloke ‘Billy’ (as in Billy Bunter) and a non-reflective bloke (am I still
allowed to say that? I want to say black
man, but I know that’s illegal now) ‘Chalky’.
So, for example, I was flattered, not offended when my ever considerate CO
in the Army at his weekly ‘O’ Groups, clearly reluctant to overtax his
subordinate would, with an appreciative nod in my direction often state, ‘No
point asking Captain Stupid’.

They had
brought with them an impressive variety of filters, gaskets and seals as well
as the reconditioned head of my generator engine. They had, they claimed, removed about two
kilogrammes of sooty carbon and clinker from the ports which did not make the
heavy cast iron lump feel any lighter but certainly left it looking cleaner and
rather like someone who had rapidly sucked a handful of Fisherman’s Friends,
able to breathe easier. The problem,
apparently, is that the generator is running under a woefully insufficient
load.
 |
| US$665 worth of filters, gaskets and seals |
 |
| So that's what a head is supposed to look like! |
Without a
decent load, I was told, the engine would run inefficiently, half the diesel
fuel turning to clag rather than burning clean, and produce far more pollution. I was not only wasting fuel, I was damaging
the engine as well as our precious environment.
Diesel engines, like women, need to be worked hard to get the best out
of them.
And that
got me thinking. Most people who are off
grid buy generators powerful enough to cope with the maximum load that can be
expected but virtually all the time, these generators are just yawning along
well under capacity. I considered my own
case, what were the chances I would have absolutely all my electrically powered
devices running at the same time? I have
some heavy load items on the circuit, the water pump, the oven, the washing
machine, several air-conditioning units and seven large fridges and freezers
but they are never all running at once.
The pump only clicks in if the water pressure drops as a tap is opened
and shuts off as soon as the tap is closed.
The oven is on about twice a week and then only for a couple of hours,
less if all I am doing is crisping up yesterday’s bread, and things like aircon
and fridge compressors only spool up as required. At any one time, the most my appliances were
drawing was about 5 amps on each phase, perhaps an extra ten when the ice cream
machine was freezing the mix. Had I
known when I ordered the ice cream machine that merely by digging a well I
would encounter a reliable supply of fresh cool water, I would have ordered a
water cooled machine instead of the power hungry air cooled model I have now
but even so, it is hardly worth my generator getting out of bed in the morning
just for 25 amps.
I have
decided, therefore, to install a hybrid system.
The extra amps the generator is capable of producing will be used to
charge a bank of batteries. While the
generator is charging the batteries, it will be running at around 80% capacity
and far more efficiently. Once the
batteries are charged, the generator will switch off and my power requirement
will be drawn through an inverter from the battery bank. The generator will run a third of the time it
is currently running, I will save loads of fuel and treble the service
interval. By running the generator at
full chat for a shorter period, I will actually reduce my carbon footprint. Before anyone congratulates me for Going
Green, let me assure them that my motives are to save money, not the planet
which is why I will not go the whole hog and install tens of square metres of
very expensive solar panels. With diesel
costing 40 cents a litre here, it is cheaper to run a generator.
 |
| Note the clinically clean environment in which the engine is being reassembled |
With the
engine bolted back together, the time came to start it. I had no idea whether the influx of water,
normally occasioning disastrous consequences for a compression ignition engine,
had stuffed the bottom end of my motor.
Jako has the optimism which only comes along with a deeply religious
upbringing. If your belief is intense
and sincere enough (I fail on both counts) nothing can go wrong but if it does,
it is merely God’s mysterious way and nothing to get upset about. I have known Jako for must be six years
now. When we first met, we had to come
to a mutually acceptable understanding.
He had to understand that my soul was, in my opinion, beyond salvation
so he need not waste his time. I just
wanted to understand him. English is not
his first language, as it isn’t for many Boers who were, let’s face it, yet
another race treated appallingly by the English so were understandably
disinclined to learn the hated sprache.
With his help I learnt to understand the peculiar syntax and grammar of
Afrikaans English. I give you a simple
example: ‘I are wearing a jeans pant’.
Jako was
standing at the downwind end of the generator when it coughed into life. He immediately disappeared in amongst a cloud
of the thick white smoke spewing out of the exhaust. Fuck me, it never did that before, I
thought.
‘Normal!’
shouted Jako coughing his lungs up, ‘they always do that after a rebuild!’ The guys quickly shut the generator down
again. We all moved upwind and gave it
another go. This time it started easily
and the smoke quickly disappeared. I was
delighted. Marcia appeared looking
equally happy. Then I noticed Jako and
the Sri Lankans weren’t sharing our joy.
Actually, they looked anything other than happy, not quite ready to
throw the towel in but still the wrong side of glum. I said nothing and Marcia folded her arms in
the way women do when they suspect things aren’t going as swimmingly as their
husband’s had suggested.
It was only
running on two of its four cylinders.
Injectors were swapped around to see if the fault followed them. It didn’t so the injectors were OK. I heaved a huge sigh of relief. These things are indecently expensive. The fault was traced to the injector pump. This is hideously expensive and can only be
properly rebuilt and set up in a laboratory.
My heart was in my boots again. The
thing is, and there was no point me trying to kid myself, I had not been able
to tell the difference between a diesel engine running on four cylinders and
this one running on only two so there was no telling how long it had been
running like this before it finally gave up the ghost. If the pump was knackered then, once again,
it was my fault. The fuel system had
been fitted with an extra, very expensive and very efficient fuel filtration
and water separation unit made in Germany and universally held in high regard
by those who know what they are. I
didn’t. I did not know that the unit I
thought was merely a water separator also contained a 10 micron filter so never
changed it. Naturally, these guys knew
all about Separ Filters and the first thing they had done when they were
stripping the engine had been to attempt to remove this filter. I say ‘attempt’ because through such
prolonged neglect, it had collapsed and was bloody hard to fish out of its
housing. If the pump was gummed up, this
was why.

At times
like this, rather than moping over the shoulders of those who really do know
what they are doing, it is far better to
leave them to it and get on with something within one’s limited skills base. I went back to the kitchen and busied myself
finishing off the much delayed lunch. I
was just cruelly boiling lobsters alive when Jako came in and asked if it was
OK to throw the trip switches on the generator to feed power to the house and
shop.
‘Is it
running?’ I asked in astonishment, ‘I can’t hear it!’
I looked
through the kitchen window. Normally, if
the generator was running, there was a faint exhaust haze discernible. I couldn’t see any sign of it. I had to go out onto the veranda before I
could detect a very gentle humming noise.
I was impressed.
‘I just
need to shut the small gennie down and take it out of the circuit,’ I said
hurrying off across the garden. They
waited until I got to the big generator before throwing the switch. The revs hardly altered. ‘No load,’ they said knowingly.
'So what was wrong with it in the end?' I asked.
'You got shit in the injector pump,' replied Jako.
‘Really?' I said. 'How often should I do that?'

| A typical snack at Fort Hippo's |
We had
lunch and then the generator alarm went off.
This time I remained calm, it was only a low fuel warning. Jako and Marcia headed off for the gas
station to fill the drums with diesel on Jako’s car while the Sri-Lankans and I
set about changing the oil on the Jeep.
If you recall last week’s episode, I had drained the oil from the
generator and changed the oil filter with a new one, not the correct one but
one that fitted, that I had found lying around amongst the mechanical related
clag I kept in a box under the house.
Since, after an engine rebuild, it is always advisable to change the oil
and filter after only a few hours, it was decided to run with my filter rather
than the new Perkins one which I would use when I changed the oil next week. The Sri-Lankans told me that the filter I had
bought for the Jeep would not fit. Sure
enough, the new filter supplied by Jeep downtown had a much larger diameter
thread. Naturally, I was reluctant to
put new oil on the car and then fit the old filter. That would be like washing your hands
scrupulously clean and then drying them on an oily rag. ‘See if the Perkins filter fits,’ I told
them. It did. So I now have a generator running with filter
for which the true application is unknown, and a Jeep running with a Perkins
filter. Never mind, that’s two oil
changes needed in the next few days.
Jako and
Marcia crawled up to the shop in low gear.
An old white guy on a push bike was following close behind. I looked at Marcia quizzically. ‘He’s German,’ she said. Oh well, that explains it then, I thought. ‘I found him at the petrol station,’ she
added as if he were no more than a particularly interesting bit of driftwood
she had stumbled upon, ‘he needs a place to stay.’
‘I am
looking for somewhere to stay,’ he said, no doubt to eliminate any doubt. Do I really wander about all day looking
confused?
‘What sort
of place are you looking for,’ I asked him in German, ‘a tourist place?’
‘Somewhere
very cheap,’ he said.
‘That’ll be
us, then, ‘ I told him, ‘wheel your bike up to the cottage.’

| A 61 year old German and his 28 year old 'bike |
Dr. (Ing.)
Stefan Frotscher is 61 years old, comes from Coswig near Dresden and is barking
mad. He is riding from Cape Town back to
Germany on a 28 year old standard bicycle which, were it not missing a basket
in front, would look like the sort of wheels a butcher would issue to his
delivery boy. His only luggage consisted
of a couple of small panniers front and rear the limited volume of which, he
admitted, was mostly taken up by water.
He had covered 121kms that day and was, he said with heartfelt sincerity,
‘very hungry’. There are only two places
he could have stayed around here that night, the cheapest of which was $400 a
night so he was bloody fortunate to have run into Marcia. He was even more fortunate that the Sri-Lankans
had not eaten everything so, much to his delight, he was immediately served a
plate of chicken curry and a couple of lobsters with a nice dipping sauce along
with an ice cold beer. His timing had
been perfect; two hours before, we didn’t have any cold drinks. He was halfway through Angola and, best of
all, did not speak a word of Portuguese.
His next country will be Congo.
He doesn’t speak French either.
After
dining, of course, he really wanted to bathe.
I showed him to his room and told him to dump all his kit in a pile and
I would run it through the washing machine for him. All through Angola he had been sleeping in
medical posts or police stations and washing out of buckets. Figuring that he already knew water in Angola
was a precious commodity so he would probably just have a splash and dash to
save my water, I told him about my well and its limitless supply of fresh,
clean water. ‘Sie können ruhig unser Wasser gnieβen,’ I assured him. The sum total of all his clothes (I had lent
him a fresh set of mine) wouldn’t have stretched a Tesco’s carrier bag so I
threw a load of my stuff into the washing machine as well.
When he
came out, much refreshed, I asked him if he wanted to catch up on the news in
German. He did, very much. As I switched over to Euro News and changed
the language, I casually asked him what he thought about Angela Merkel being
dismissed for drunkenness. ‘WHAT!!!?’ he
exploded. I had intended to wind him up
further knowing he must be months behind on current affairs but the thought of
old Angela being tossed drunk out of her office had clearly nearly given him a
heart attack so thought I had best not tell him that Germany had pulled out of
the Eurozone and changed all deposits held in German banks from Euros to
Deutsch Marks at a one to one rate; the last thing I needed was to explain a recently
expired German to the Angolan authorities.
As I have
already intimated, there was something quite eerie about Dr. Stefan’s
timing. There is an old Portuguese guy
who has a bakery on the outskirts of Luanda where we used to live. He has a van and working to a strict schedule
best described as ‘when he feels like it’, he runs his van full of bread down
to the Barra de Kwanza to sell it to the two tourist lodges and Marcia’s
shop. The bread is really nice,
especially his rolls, quite unlike anything bought from the State bakeries and
very similar to the bread available in France or Germany. It freezes well and is delicious when crisped
in the oven. To announce his arrival in
the village, he has fitted an ice cream van style electronic Glockenspiel to
his van with a volume control which is either off, or more usually on so you
can hear him coming miles away. I was
just making an early morning pot of tea and had only just asked Stefan what he
missed the most and learnt it was buttered fresh brötchen with jam for
breakfast when I heard the Glockenspiel.
‘Is that an
ice cream van?’ he asked.
‘No,’ I
said, ‘it’s selling your breakfast. Why,
do you like ice cream?’
‘I love ice
cream,’ he confessed.
‘What flavour?’
I asked.
‘Sahne’
Timing
again. Now that the power was back on,
Marcia was mixing up a batch of ice cream.
Our machine can do two flavours at a time. I asked Marcia to make one of them rich cream
and the other, just so he had a taste of the tropics, coconut flavour. It is also bloody fast, probably why it draws
so much power. Stefan enjoyed his fresh bread
rolls with butter and Guava jam and for me, the sight and smell of it was so evocative
of my time in Germany, for the first time in years, I had breakfast too.
Andy
Mallett appeared in the doorway along with Richard, a mutual friend. Keen golfers, they had just finished an early
morning round at the nearby resort and dropped in, as Andy stated, to quality
control the work on the generator. Lunch
was Tagliatelli Carbonara with ice cream for dessert.
By now,
Stefan was making some serious, ‘I’ve got to go’ noises. He intended to split the seventy odd kilometre
trip to Luanda into two stages as he only needed to arrive in Luanda on Sunday
so that he could get his visa from the Congolese Embassy on Monday. There is only one sizeable village between
here and Luanda and while it offers places to stay for tourists, the cheapest
is about a 100 bucks. Furthermore, it is
only 25 kilometres down the road so seemed to me hardly worth the effort; after
all, he had covered 121 kms the day of his arrival. Why didn’t he spend another night with us and
start off very early Sunday morning and do Luanda in one day? He was adamant. He would never spend more than one night in
the same location otherwise, he said, he would never get back to Germany. Fair enough, I thought, but I still felt he
would end up cycling into Luanda in the early hours not having found anywhere
to stay on the way. Marcia wrote him out
a note in Portuguese which stated.
‘Hi! My name is Stefan, I am German. I am riding from Cape Town to Germany and I
would like somewhere cheap to stay the night.
Thank you for your help’
Cynically,
I thought this translated as:
‘Hi! I am
vulnerable, please take me down a dark alley and rob me’ but kept such unpleasant
thoughts to myself.
Before he
set off, I noticed him carefully logging his mileage in a book.
‘How many kilometres
have you done with this 28 year old bike?’ I asked.
I was not
ready for the answer.
‘342,000
kms,’ he said indicating the speedometer on the bike.
‘Bloody
hell!’ I said, ‘you must have done some long trips on it!’
‘I have,’
he confirmed, ‘don’t forget, I had to ride to Cape Town from Germany down the
eastern side of Africa before I could ride back up the western side…’
He thinks
he will get home by March… next year.
