Thanks for the manual.
Also I'm getting the bearings for the EBX7500 today and will post measurements and number on bearing.

Make a note of the original seal depth.
Usually drilling a small 1/8 hole carefully into the seal face without pushing the bit into the housing or bearing hard works. Use a small cheap body dent/seal puller and insert the screw into the hole. Tap the weight back and the seal will pop right out pretty easy.
To insert the new one, pack the back of the lip seal with grease to keep the garter spring in place. Start by hand, paying attention not to roll the lip seal and then tap it to the correct depth with a section of PVC or a metal pipe carefully.
Do not use a screwdriver or blunt punch to set the depth of the seal unless you want practice doing it over.

Thanks have done large seals like this but wanted to know about doing it to the blower.

Some seals just will not have enough room or material to risk removing them while the end closure is still in place.
You are referring to the engine crankshaft PTO/ output oil seal?

The seal appears to to be a TC16x27x8 seal which is a rubber coated seal.
Here I made a hook tool out of old long skinny screwdriver and extract these seals with it using the end of the crankshaft as a fulcrum point. Now it does take fairly strong hook to do this but rubber coated seal are a lot easier to remove than the metal only ones.

I was thinking along the same lines to pull it.
There is some metal (not much) to possibly use a long sheet metal screw also.
