RICHARD - Good friend was a heavy truck mechanic. He actually had a LOT of the special drivers for seals & bearings made that were shown in the service manuals for the trucks & components he worked on.
Just the two drawers of his roll-around tool chest that held the frequently used drivers was heavier than ALL my tools combined.
Lots of BIG brass & steel drivers.
The Kohler Classic manual shows drawings for the seal drivers, but if your installing HUNDREDS of seals a day, you need what they show. If you do a pair every year or two, you don't need anything that fancy. My SON worked at a gearbox mfg. plant for 1-1/2 yrs building gearboxes that were BIGGER than a CC and weighed as much as a half-ton pickup. Most seals he installed with a piece of pipe/tubing and a block of wood over the end. On the BIG seals for the 5 to 8 inch diameter shafts he just used the block of wood laid across the face of the seal.
