Cabriolet Hydraulic Roof Pump Refill - [ROVER-CX8 Project]


When I got my Cabby I noticed the roof was very lethargic and required a push to get it moving
but recently it had become useless at raising itself up again, needed two people last week, I
have owned FORD Escort Cabriolets in the past and they suffered from a similar problem but
it was down to a failed pump cog, this doesn't seem to be the case on the Rover variants as
the pump is mounted vertical compared to the horizontal position of the Ford units which
must make them work harder.

After a quick investigation I found the fluid level was very low and after asking around on
here decided to refill the unit with generic clutch and brake fluid.

To remove the brass grub bolt you will require a 13mm socket or spanner, be sure not to
loose the rubber o-ring seal when you remove it.



Image




To fill up the fluid I re-used a rig I made to fill my 75 clutch reservoir, came in handy for this.



Image





I only ended up putting in about 40ml of fluid to get it back to the Max mark, I then
cleaned up the aperture and refitted the grub bolt.

I had to make a couple of passes of operating do get what I guess was air in the system,
the horrid noises it was making then silenced and I now have fully functioning and smooth
roof operation, link to a quick video of the second roof raising is below, I hope this guide
helps anyone who may encounter a similar problem.
