W108 hydropneumatic compensator questions
The saga continues of the fix-up of the 1967 250 S utilizing parts from the 1968 280 S parts car. The 250 S is now drivable. I have work to do on the carbs (webers), exhaust, lots of other things.
Prior to this weekend, the 250 S had the rediculous sag and wonky camber in the back end that is associated with a bad hydropneumatic compensator. The 280 S had the spring compensator, and we switched them so now the spring is in the 250 S and the ride, camber, etc is really quite excellent.
The strange part is that the hydropneumatic compensator appears to be very recent. The rubber bits have wax on them still and after I cleaned off the grease the thing looks new. But when I push/pull the plunger it just moves with no resistence.
Is there something clever I can do with this that won't cost me $$$? Although the ride is nice with the spring, I suspect it is nicer with the hydropneumatic compensator...
