Found it best to remove the negative post power at battery/batteries first.
Take off the 10mm alt feed wire and replace nut so you don't lose it.
My 3b
Remove air filter top and hose to the intake, remove air filter assembly .
2x14mm bolts and one 12mm this allows lots of room.
Remove any plastic air filter bits in order to make room for attacking the long mounting bolt.
Loosen 12mm alt belt adjustment bolt.
Remove belt
Pull alt towards fender to remove 19mm vaccum hose ass. Nut(careful with copper washers) This gives you lots of room
Disconnect plug
Push alt towards engine and remove the long 14mm mounting bolt.
Remove banjo bolt, again careful of washers and then return line.
Take your time and either place parts in order in a clean spot or replace where they came from.
Be methodical you cannot afford to drop and lose parts.
It's to bad because I had a 2L alt in my hands last Saturday morning. I should have bought it to repair my unit.
Left it on the front seat of a 2.4D pick up in Watson Lake Yukon Territory.
Engine is supposedly pooched but there are parts like IP, starter for those interested. BEE JAYS garage up in the bone yard.
