CM2250 loud engine whine, need advice

[redbeard]

Listened to all three videos. I’d be considered also. Have you tried the big screwdriver up to your ear to help pin point the noise?
These 2250 have a couple of issues under the front cover. One being fuel pump drive bolts shear another is the scissor gear has been upgraded.
Could be power steering pump, does it get hot quick?
I would start it up and just start touching for warmth on everything and listening with screwdriver on hear to help at least get close to sound. You really need to get an idea where it is or is not coming from, I’m sure it’s driving you crazy
