Disassembling Axle
1) Remove grease port screw completely and replace it with a longer screw with identical thread. Screw it in partially and use it to pull out the dust cap. Alternatively, you can partially back out the much shorter original screw and grip it with pliers.
2) To ease the release of the pedal body retaining screw, slightly heat it up with a soldering iron.
3) Secure axle with a 15mm key wrench and remove screw with a T-20 sized Torx tool.
4) Pull body from axle.

At 76.02mm the Titanium axle length is about 3mm shorter. Take this into account with cleat placement as your Q-factor will now be 6mm less.
Putting it back together
1) Degrease the axle threads and Torx screw.
