Some of you may recall I crashed at Kames last year and broke many things – I kept the shock as a memento but it’s been sitting on my bench for over a year and curiosity got the better of me. They have potentially fatal pressures in them, so don’t try this without researching it properly, but it’s a 5 minutes job to dismantle once you’ve depressurised it.
A mono tube design with gas behind the first piston. The gas allows the rod to enter the shock absorber and keeps the oil pressurised to reduce cavitation. The piston has what looks like a PTFE or teflon sealing ring.
The piston has holes in it that cross over from inside to outside as they pass through.
The inside holes are covered with thin washers which act as the valves. The rebound side has two notches that presumably act as a bleed to prevent lock up.
The washers are used to set the valve rate and stack up like a leaf spring.
More washers are on the compression side, less on the rebound. The green washer is the internal bump stop.
The top bearing with it’s integral primary seal. Damage can be seen where the rod snapped during the accident.
Yes, I know I’m sad . . .
