Is the crank locking pin behind / above the starter, (like a proper engine) - it's about the only but not on your pic.......
Guessing it's a spring-loaded aux belt tensioner too? (I have small hands

, but a feeling I won't be immune from shedding a bit of skin

).
Look forward to the next thrilling episode of why doggy should stick to the day job.

ididnt lock the crank off. ijust Made a Marker. its easier,
The Aux belt is a Mare. you need two sets of hands, get someone to hold the aux belt on the crank pulley whilst you route the belt
theres no room in there, so expect a few scrapes on your arms,
