[Healeys] Overdrive accumulator piston rings - BJ8

[Mark Schneider]

Yesterday I was seeking advice on techniques for successfully  
installing an overdrive hydraulic accumulator piston in the housing.   
As I have never done this before I was having difficulty compressing  
the 4 small steel rings while they are fed into the housing cylinder  
bore.   I solved the challenge myself.  In truth I may have only  
duplicated what others have done but it worked and it may be worth  
sharing.

I visited an automatic transmission shop and showed the owner the  
Healey OD accumulator piston and housing tube.  After a little  
searching he produced a small metal ring with the exact same bore ID  
as the housing.  The ring was only about a half inch long but it was  
perfect for compressing the rings.
