diesel starter motor

Evening all I have a problem with a diesel starter motor, the problem first occurred about a month ago ,an audible click could be heard when turning the key but no rotation followed .I researched this in the forum and was happy to find that the most common fault was the contacts,and very little else ever went wrong. I replaced the contacts which were quite badly pitted and burnt and until now all has been well until today. The same audible click
occurs but much louder but again no rotation so it seems that the solenoid is throwing the pinion into the flywheel quite briskly but not turning. I have found that if I tap the starter body [not the solenoid] with a blunt instrument the motor will start.From days of old this suggests to me a bad spot on the comm ,Is this a known fault ,and how difficult is the remedy. I would be most grateful for your replies.
