I am rehabbing a Doctor Who and have replaced the faulty Time Expander motor/gearbox. The assembly now raises/lowers great but I cant figure out how to make it level with the playfield in resting position. The two mounting brackets sit on top of the playfield so I can see raising the unit would be easy with some washers but not sure how to lower it. Any suggestions?
Attached are some pics so you can see what I am talking about. The left side is slightly raised off the playfield (maybe 1/16-1/8") and causes balls to be deflected.
