If you did take it apart, yes there are a lot of items in there that have to be installed by aligning marks or features of the parts. I am attaching a repair procedure that I believe covers your system. You will have to look at the last page and see if your torque generator numbers match any of those in the list. And unfortunately the numbers are on the mounting surface against the gauge plate. If you have any questions Google Midwest Steering Independence, MO and give them a call. Their site is where I found the diagram and also where I bought my seal kit. I did not entirely disassemble my unit, I knew they are very finicky about proper assembly and only carefully pulled off the end caps and resealed the in an out shafts. Good luck!
