My latest assignment is the overhauling of an unfortunate, poorly managed DEUTZ, 04 cylinder, water cooled engine coupled to a new COMPAIR C115-12 portable air compressor. This engine was in its infancy and had not yet completed initial 1000 hours of operation when a group of some pseudo specialist mechanics knocked it with all their comprehension of fuel injection systems rendering it unusable for the rest of the life of this fine-looking portable air compressor by damaging its timing gears and associated cam shaft.
The durability of air cooled DEUTZ engines has always fascinated me. Gone are the days of my student being in University of Engineering & Technology (Lahore) when I was under the false consciousness that air cooled engines cannot be operated in the hot, rather harsher climate of Pakistan. Things have changed for me completely after spending four years in the field of earth moving and construction equipment and a bit after reading "Roland Sparling" who leads his life in line with his sayings which are as under.
"Items that are not there, cannot fail!"
"If it ain't broke, don't fix it!"
"There is no such thing as a water-cooled engine, just those that use water as a
Heat-transfer medium, so if you can cut out the Middle-Man, why not?"
"After making the move to Air-Cooled Power, why go backwards?"
"A Porsche with a radiator is not a REAL Porsche."
Anyhow, if it had been the livelihood of some private contractor, lives would have been complicated at least for the pseudo specialist mechanics. But for a company like ours, we are least bothered about the future utilization of this machine. Most probably we are going to declare it scrap.
Besides, I have indented spares in order to raise a tender enquiry for complete engine overhauling of this machine to make it easier for the higher management to decide whether to scrap it or repair it on the basis of prices received from various bidders.
