Hi and welcome to the forum, hrastovica. First of all ... where are you located (it can be helpful when recommending good engineers / repairers if we can make them local for you). Also ... some of our more mechanically minded members may live close to you and be able to give you good advice or help.
I'm sure someone will come on (possibly in the morning) and be able to answer your questions.
Cheers,
Dave
