I have a question about the hydrolastic system.
How important is it to use a vacuum pump before refilling. What effect would air have on the ride?
I have purchased a cheap grease gun type pump, but am wondering if I have wasted my money. It worked on my Rover 100 cabriolet for a straight pump up.
Will it work if I depressurise the landcrab and replace the bearings etc. Is there a easy way to vac the system. I.E. cheap.
Regards Kels.

If the system was empty due to work, it is essential to have it evacuated before refilling. For a pump-up this is not needed. If a hose or pipe has been changed and the Hydrolastic pots have not been emptied, it might (just) work without evacuation, but I'd 'bleed' it at the joint opposite the fill valve before putting pressure on.
If you just depressurise the system to change something outside the hydrolastic system itself, it will usually be fine, as air should not enter the system in this case.
The effect of trapped air can be, depending on the volume, very noticeable. The car can be very, very soft and hardly damped at all. You surely can pump it up and carefully drive it to someone with a proper pump after a rebuild - probably preferred to driving on the bump stops.
Regards,
Alexander

Have been using a grease gun type for a few years on a W6 with no noticable difference to the ride from it being done with both the 'dalek' type of unit or the portable type. Also, a lot handier than having to go to dealers for top ups!

Has any one found a cheap vacuum pump? what vacuum does the Dalek pull?
regards Kels.

I have another question regarding the hydrolastic set up.
Are they the same displacers etc used on the 1100/1300 or are they different (bigger i'd imagine?)?
Cheers

am wondering if I have wasted my money. Not at all. I use my grease gun pump all the time, although I do have a darlek as well. |

Cheers Keef,
wanted to know if it'd be worth getting a set of ADO16 ones and storing them, they come up for sale here once in a while

Cheers Keef, wanted to know if it'd be worth getting a set of ADO16 ones and storing them, they come up for sale here once in a while -Andrew Always a good idea to save and keep displacers. Don't throw away broken ones either, as they could be rebuilt. Tommy:-) |

Wouldn't dream of throwing any out even if broken, Dr. Moulton wouldn't be happy!
