Old but amazing casting for car alloy wheels

 We all thought that beautiful mag wheels are only built by modern machinery and casting technology .  But here we can see that sand casting produce alloy wheels cheaply and also beautifully.  Lot of grinding and polishing to do of course.   But it can be done

The inputs are scrap aluminum from engine blocks and other scrap aluminum parts/junk

Beatufiful.  Amazing

Complete repair/rebuild of 6 cylinder Nissan Diesel Engine

 This is admireable.  With limited machinerry repair and measuring equipment.  But judging from the way the engine purrs they must have done an admireable job.

If we compare the Western repairs:

1.   Proper use of measuring tools:    torque wrench, roundness gauge, calipers

2.  Clean workplace

3.  Proper lubrication

4.  Plenty of helpers in Pakistan

5.  Westerners would always go fornew complete assemblies which undboutedly are more expensive

With limited knowhow and equipment these workersk/craftsmen have done a wonderful job





Roadside repair of jammed truck transmission

 It could be misleading because the transmission unit was removed and repaired at a machine shop.  This was probably in Pakistan.

However it was a superb job.  No need to tow the heavy disabled truck.   Only a tricycle was used to transport the damaged transmission.   We should admire the mechanic who know excatly the sequence of the gears.





Black smoke after replacing turbos and injector

 It could be due to the intercooler.   Signs of defective intercooler:   black soot and oil at the underside from the leak.
