Depressurisation, how to do it yourself
I recently depressurised my hydrolastic system. I used an
attachment off the end of a bike pump. I had to cut the end off that
normally goes into the pump as it contains a one way valve. Seemed to work very
well, could put one end in a bottle to catch the fluid and adjust the bleed rate
by tightening or loosening the screw on connection.
Hydrolastic Suspension Units
This is a (incomplete ?) list of the unit numbers for different hydro units:
Standard Components

| 21A1477 | Cooper (Front or Rear) | to 830000 |
| 21A1804 | Cooper (Front or Rear) | to 1025600 |
| 21A2008 | Cooper (Front or Rear) | 1025600 on |
| 21A1872 | Cooper S (Front or Rear) | to 1025600 |
| 21A2012 | Cooper S (Front or Rear) | 1025600 on |
Special Tuning Components
| Part# | Application | Colour Band |
| C-21A1693 | Rally (Front) | 1 Yellow |
| C-21A1705 | Rally (Front or Rear) | 1 Yellow |
| 21A1811 | Rally (Front or Rear) | 2 Orange |
| C-21A1819 | Race (Front) | 1 Red |
| C-21A1821 | Race (Rear) | 2 Red |

These part numbers are from the Austin and Morris Mini Cooper and Cooper 'S' Mechanical Service Parts Catalog (AKD 3509) from 1965, so they should be correct. It does include exact(?) body numbers for each of the units but the list would be a lot longer....
