Getting the wheel off the drop arm is one of the notoriously difficult jobs on the Seven.
DO NOT HIT THE END OF THE SPINDLE
It is soft and the gear is very tight.
I eventually had to make a puller out of 5mm plate, put the assembly in the freezer overnight, heat the gear (but it blues easily) and hit the puller bolt with a large hammer - and then it came off.
Then I had to make good the damage I had done to the spindle by hitting it.
It is the obvious thing to do - but don't do it.
Having done that, you then have to lap the gears together with grinding paste.
I have just done that with a box with the gear worn in all three positions. After about 4 hours or so I am about 85% there and will try it to see if I can get away with it.
"Find another box" - this is my other box!
