I have the pulley off the unit but can't seem to take it down any further? I want to get the resevoir chromed but cannot figure this thing out. I already removed the two bolts on the back where the hoses go but it seems to be stuck.
There should be a lip on the reservoir. Clamp the cast iron portion in a vise (there is actually a convenient extrusion). Using a piece of wood tap around the reservoir on the lip to separate the reservoir. On mine, I had to tap real as it had been siliconed by a po.
