Stihl 024AV Clutch/Oil Pump Question

[HumBurner]

I need to reread the service bulletin, but I’m thinking the oil pump may need to be changed out as well. When I was test fitting the large drum on mine to see if if would work, it appeared to be hitting the pump more so than the case. Not a difficult mod, but definitely adds cost.

Right on.

I know the avs model I have has an adjustable pump, but the av model does not. That may also have an effect on clearance and what will work vs. won't work.
