Compressor removal
Hopefully a tip that will help others.
When removing the compressor for overhaul or replacement, the top bolt holding the mounting bracket is quite fiddly and time consuming to remove as it’s partially hidden.
It is possible to remove the small cross head screw that secures the dryer to the pump, highlighted in the red circle, (possibly with a cross head screwdriver bit held with pliers to get it started ?) then twist the dryer anti clockwise slightly and pull towards the front of the car and off it’s mounting lugs. I refitted my unit this way in a few minutes and was able to slot the dryer on, twist then put the screw in by hand, using a screwdriver bit and pliers to nip it up.
