Japanese Airfields, Equipment & more #12 - revised

IJAAF & IJNAF crank engine starter or inertia starter
To be honest, I can't remember ever seeing a Japanese aircraft model with a crank starter sticking out or even placed on the ground. A very small detail that would make any model a little bit more realistic.

Wiki says: 
"An aero engine inertia starter uses a pre-rotated flywheel to transfer kinetic energy to the crankshaft, normally through reduction gears and a clutch to prevent over-torque conditions. Three variations have been used, hand driven, electrically driven and a combination of both. When the flywheel is fully energised either a manual cable is pulled or a solenoid is used to engage the starter."

Ground crew using a crank starter on a Tachikawa Ki-36 "Ida" ground attack and liaison aircraft.

Same scene but this time the aircraft is a Mitsubishi Ki-46 "Dinah".

I bet you didn't know that the Nakajima Ki-43 "Hayabusa" (Oscar) had the crank starter hole inside the starboard wheel well.
One more "Hayabusa" photo, this time a 64 Sentai fighter.

This photo of a Kawasaki Ki-100 gives a very clear image of an IJAAF crank starter.

With the IJNAF fighters, very often, the crank starter was placed in the undercarriage leg as depicted by illustrator Sato Kunihiko in Model Art #857 or Profile #13.

This practice was not uncommon with the Mitsubishi J2M "Raiden" (Jack) too.

Or it was casually placed on the tarmac, like in this photo of a Zero.

A Mitsubishi G3M "Nell" and a Mitsubishi G4M "Betty" have their engines started by crank starters.

A short clip showing a Navy Type 90 Crew-trainer or Mitsubishi K3M "Pine" having its engine started. This is the only video I could spot where the sounds of the flywheel and the starter can be clearly heard.

The girls we saw in a previous post, here, start the engine of a Mitsubishi Ki-46 "Dinah".
