ok disassembly is sorta the same on non tilt, remove the wheel, lock plate and directional switch. then remove the lock housing, i think it is 8 mm bolts. again i presume it is the rack that is broken, nonetheless it is driven by the gear you purchased. the gear does have to be timed in sequence with the gear. just spend a few minutes to get familar with how it all works before you take it apart. it is not hard to do but does require patience and understanding of how it works. it will all make sence to you if you study it before you take it apart.
