82 300TD valve adjust ments

Hi guys well I am having a terrible time getting my car going again, first we took of the vavle cover and dicovered that the time gear that is on the cam shaft had stripped and broke the wedge that keeps the timing, I was able to find the wedge and a new gear but now the shop where I had the car was broken in to and the manual for the engine was stolen!!!!! so I was wondering if some could get me the specifications to adjust the valves now that I dont have the maual and it is impossible to get it here in mexico so if anyone have that information I would be really thankful.
