Well,there's not really a seperation step by step.
It's been awhile since I took it apart.
I removed tracks,front rollers,used small flat head screwdriver for the tabs,front portion of the model slips out the front with boom,bucket.Once the front portion is removed ,the cab pops off.Removed sides (guard on the sides)(w/rollers)Takes a little force to pull the sprockets off of the axles.Thats pretty much it for taking the model apart.
Hope this helps.
