how can i fix my panasonic nvhd 610 vcr.error code fo6?

cassette go stuck i managed to remove it,then i found on the right hand side plate (vxa4806) a broken piece of plastic and a spring lying on the chassis.
i ordered the spares and replaced the broken parts,only to find that the tape loading mechanism will not load the tape.i suspect that the motor for transporting the tape is also broken,please can you confirm,an would a new motor be cost effective.

thank you
