Cars Q&A

Boss, sell off the car and get peace of mind !

It does appear from what you have stated that your engine is fundamentally not developing enough power. If your engine develops enough power, it will not hesitate to carry the extra load of the AC. Your pulley problem suggests that there was an inefficient transfer of power to the AC, but that being solved now, it is clear that your engine not being able to pull is a separate problem, and there could be a lot of reasons for it. Putting random "metal pieces" to hold your engine together doesn't seem like the job of a professional at work. At some point, you will have to get to the bottom of the problem - your engine. YOU decide whether the investment is worth it.

Hi Anu,
This problem may occur due to a number of reasons.
a) Engine is not generating enough power.
b) Misalignment/loose fitting.
This "Sprocket fitted in crank" problem I could not understand. But as a Mech. Engineer I can advise you 2 things:
Fitting of metal pieces to make it tight is a bad solution as it will be misaligned and unbalanced and may damage the equipment.
As regards rectifing the problem without changing crank, this can be done. The outer dia of crank and the internal dia of sprocket has to be measured properly, if the Outer Dia of crank is less it can be builtup (repaired) by welding and grinding and if the Internal Dia of sprocket is more than a bush can be fitted to recty the problem.
