Yes,it is an E-7.I am trying to power a “B” unit that was a dummy.I should add that it is an older unit but runs very well.
If you don’t have the instruction sheets and diagrams that came with the loco, you can find them here:
Click on Literature, scroll down to Life Like. From there you can see the diagrams and “exploded” parts view, and how to remove the shell.

Early P2K versions were designed like they would never need to be serviced. The wiring is minimal in length. The weights and electronics screw in place, but can not be removed without pulling some soldered wires. This is not a problem if you have a good soldering system. You have to keep track of which wires are removed and from where.
Once the weights and electronics are removed, the motor is held in place like old Athearn BB engines.
If it was a dummy why do you have to remove a motor???
Also, if it was a dummy how do you know it runs well???
I’m guessing what you’re thinking of doing is removing a motor from a powered E-unit to put in a dummy B-unit to make it a powered engine?
If so, I’d say the easier thing to do would be just get a powered E-7 and swap the bodies. At the RR flea market I went to last Saturday, old Proto E-units sold around $50-75 each.
BTW, you do know that the A and B units use the same chassis / motor etc.? So if the powered engine you want to take the motor out of is an E-7A, the E-7B body will fit right in place. (Actually I have put an E-7 body on an E-8 chassis, but you have to do a little filing.)
