MY FIRST CAR ACCIDENT
MY FIRST CAR ACCIDENT
Way back in 1989 when I was going from Faridabad to Delhi in my first ever Ambassador car we had an accident. By the Grace of Almighty we all three ,myself my wife and my 5 years old son, were safe and scratch free.
I clearly remember that Sunday,an accident day .While cleaning the car in the morning I observed that rear left tyre was flat. The head of the cruel nail which had happily pierced the tyre ,was visible clearly.I had planned to go to Delhi ....It was obvious that to drive the car,the replacement of flat tyre with the spare wheel was essential.
Flat tyre was an opportunity for me to demonstrate my skill of how I myself can take care of small problems related to car. Till then I had never changed the wheel....but sometime will be the first time so I decided to do the job .
I confidently opened the dickey and picked the Jack and spanner.At that time my weight was hardly 52 kg so it was quite tough to unscrew the nuts but by almost jumping on the spanner I succeeded in unscrewing those tough nuts.I had observed mechanics jumping on the spanner.I patted myself for my skill of observing the things around me ! .....Fortunately car was on the flat surface so there was not any difficulty in the placement of the Jack for lifting the body of the car in the upward direction.Having done that I repalced the wheel .I took about 67 minutes for the job .I of course did not not measure the time taken for each activity but break up of the 67 minutes time was approximately like this.....
7 minutes in observing the flat tyre.
6 minutes for cursing road conditions
and the company who allotted the
old car to me.
17 minutes for un-screwing the 4 rigid nuts.
5 minutes tea break.
4 minutes for lifting the body of car upward with the help of accurately placed Jack.
16 minutes for taking out flat tyre +
inserting the spare wheel on those 4 studs
2 minutes for screwing the nuts on the protruding studs.
4 minutes for reading the news paper
headlines seeing RK Laxman Cartoon and worrying about the country.
3 minutes for removing the Jack
and
3 minutes for wind up and cleaning hands.
True that ...the time taken by me was very high but readers must understand that I was alone and had no previous experience. I was feeling bad for taking more time but with the prevailing constraints I did the job reasonably well and I consoled myself.
Now can you guess how much time is required for Japanies team to replace the wheel ?
The same job was done by three Japanies in our company in 67 seconds when they had come here to participate in Himalayan Rally in the year 2001 ......
They were working in a team and had hydraulic Jack, Battery operated spanners,measuring equipments and strong physique..dogged positive attitude !...Above all these Japanies live to work while we Indians work to live !
It will be interesting to know the the break up of time taken for various activities. for replacing flat tyre on a LCV Canter vehicle by Japanies team. The data is real as the same was measured by 3 other Japanies with stop watches. Here is the break up of 67 seconds
10 seconds warm up exercise
6. seconds for getting the tools from vehicle .
14 seconds for unscrewing the nuts and
positioning the Jack .
13 seconds for taking out wheel and putting the new wheel on the protruding studs
4 seconds for spraying anti rust
liquid on studs
14 seconds for tightening the nuts, removing the Jack and measuring tightening torque of nuts and tyre pressure.
6 seconds wind up and clapping for success.
Readers may be wondering what about an accident ? Sorry for deviating from the titled topic.
Anyway... after replacing the wheel we proceeded to Delhi as per our plan.
When I was driving, I sensed slight wobbling in the car.I asked my wife did she notice any such wobbling ? She said no. To satisfy myself I checked the air pressure after filling the petrol as flat tyre was also to be repaired...The tyre pressure was perfect.
We continued our journey....As soon as the speed was above 30 kmph I sensed the wobbleing again .This means either it was a psychological feeling as my wife commented or I could not rich to the root cause of the problem.I was wondering what could have gone wrong in my car this time.....and As I was thinking hard there was sudden sound and the car got tilted on the left and was grounded. As I applied the sudden brake in shock , I saw one sole wheel was moving ahead and it merrily travelled for more than 200 meters .
Yes.....it was the same wheel which I had replaced .
In those days there was not much traffic and because it was Sunday the vehicle density was thin ,as a result nobody rammed my car from the rear and the major damage was avoided.....In the failure analysis I remembered that I hardly took any time for tightening the nuts and started reading the news paper.... The root cause for the accident was the news paper !
Since then I never read news paper while replacing the wheel !!
