Generator blower motor broken pulley - Guy - 11-24-2018

I wanted to put this post under Generators. Please feel free to move it.....

Our 1984 Newell with a 12 kw Perkins gen set has been shutting down after 2 or 3 hours run time. Doesn't matter if its Yuma in July, or the other day in Denver at 15 degrees. Our old analog gauges indicate oil pressure and coolant temps are fine. Oil level is ok, and no coolant is being expelled by the gen set.

 Today I decided to give things a good look, and have become side tracked by another unrelated issue.   ( See attached photo)  The pulley on the motor driving the blower is broken. I have never seen anything like this. I am assuming it is die cast, and at some time in it's life someone has tried to remove it with a good blow with a hammer?

The blower is old with brass bushings, and is very noisy so I think the time has come for a new blower, and a replacement pulley.The original blower is a very obsolete Grainger 2C975 . The current Grainger offering is 5NRD2. It looks like there will be a little welding of sheet metal from the old blower to the new unit.

Can anyone who has been down this trail please chime in with your experience? After getting this done i will focus on the shutdown issue.

I pulled the blower , welded and reinforced a couple cracks and replaced the bushing bearings with sealed ball bearings. There is a thread on this site about blowers etc. I cannot find it at the moment.
