Cars Q&A

Get it checked again by another authorised Service station,preferably one operated by an authorised dealer. It is possible that solution may lie in replacing in the pulley/s.Gettingthe crankshaft may entail more expenditure which may be avoided if an expert advice is given.But, for heaven's sake, do not again go to a Roadside mechanic. Also check with the person from whom you bought the car and find out what the problem was and how he had got it fixed up and from where.Maybe that may help.

Dear sir,
If you can check it outside the authorise service station then I would like to suggest you please go Model Town near Metro Station and Meet Mr. Harjeet Singh on Sonu Automobile he can solve your problem or he will check the exact fault.

The problem could be that the dimension of the ie the dia of the shaft or the hole in the pully could worn out. Try changing only the pulley or add metal and turn it out in lathe to fit the crank pulley. Opening the engine to check the crank will cost you money. The crankshaft has to be balanced, head gasket changed. Since the engine has to be opened it better to check the clearance of piston/cylinder and change the piston rings to get better compression. pl use only authorises hyundai service centre

Impossible for the crankshaft diameter to change or wear out in 3 years.
The fault will be with the mild steel pulley.Replace with an OE pulley and check if there is any 'give' before tightening the bolt.If there is a noticeable play, then you need to match the crankshaft diameter by sleeving and machining the inner diameter of the pulley.
