It first of all concerns difficult, expensive details, such as the engine, the generator, a starter etc. sometimes offer Such possibility both official representatives, and free sellers of spare parts.

It also saves some part of your means, in most cases essentially enough. Thus the firm selling the restored unit, gives on it almost same guarantee, as well as on the new.

Identification of spare parts
