I have exactly the same issue and Mitsubishi SA cannot supply the part. Order from Japan in 21 days if all goes well. I am stuck in Port Alfred in the Eastern Cape. Any info on PartsHunt or where else I can get the part from please? Will send a courier asap. Crank pulley Mitsu part number ME204075.

We then took it to a different mechanic recommended who discovered that the front crank shaft pulley was rubbing against the timing chain cover. The pulley has a rubber insert in it as a damper this had become detached and caused the pulley to rub against the cover. We got a second hand pulley from PartsHunt who were very helpful. After fitting the pulley no more noise and I have fallen in love with my Pajero again. I hope that this will be a useful experience to other owners when trying to identify mysterious squealing noises at the front of the engine.
