<div>The accumulator is in two pieces. There is an outer housing or liner which was used by Austin Healey to reduce the size of the accumulator piston and by that means the OD’s engagement force, and the smaller inner piston which actually stores the hydraulic
force. In order to replace the O-rings you have to remove the housing first. To do this you need to block the motion of the piston. I’ve done it by holding the piston in place with a wooden dowel while applying air pressure to the control valve port. Any compressor
you have should be sufficient to do this. Use a rag to catch the liner when it comes free as it will come out with some force. The liner is sealed with one O-ring on later ODs and that is where operating pressure is usually lost. The piston is sealed within
the liner bore by steel rings. These are not usually the source of your problem.</div>

<p class="x_MsoNormal">Yes thanks for the tip. The problem is slow to engage. It was suggested maybe accumulator O ring. Just did pull the check valve and all. Did seem like dirty oil. I cleaned it all up. I’m already committed to extracting the accumulator
and piston but wanted to replace all the tranny mounts and bushings which I did. Mounts were pretty squished and cracked. Bushings(radiator saver)were fairly solid but were replaced. They were the original. Cleaning and degreasing as I go along.</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">If(?)it is the O ring or rings, I guess they are metal on the piston, I might just spring for a uprated from Dennis Welch or AH spares has a combo housing/piston both which have rubber O rings.
</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">Working my way to the extraction part. I want to use forced air through the operating valve but I only have a small air compressor for tires. Some kind of extraction tool would be helpful. (18G182) I have always changed tranny oil regularly.
Used ND 30 early on. Using MT 90 now for many years. </p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">Any and all suggestions appreciated.</p>

<p class="x_MsoNormal" style="margin-bottom:12.0pt">Warren- Don't know the OD problem you are experiencing, but suggest before you tear into it, undo and clean the check valve and ball on the top right side (if you haven't already done so). One small spot of
dirt lodged in the valve drilling can kill the hydraulics and make it seem like a bigger issue. It may be worn parts, but, if not, this is an easy first test. If it is dirt; good idea to change oil and add fresh SAE 30W non detergent oil to the unit. Regards,
Hank, healeyhelper.com</p>
