Koni rebuild
« on: September 18, 2019, 10:41:30 PM »
Thought some may be interested in what's inside a Koni. Shown is a 4-65 dated SP-1 82-1326 front shock, a different shock than the later SP-3 82-1388 unit. The valving in both are basically the same, but the threaded gland nut top is a totally different setup making the internal seals and piston rod/cylinder sightly longer in the 1388.  Shocks dated 11-64 SP-1's have an even different internal configuration and valving from those dated 3-65.  Many production changes over months which seem to minimize machining requirements, number of needed parts and simplified assembly. This unit was toast with a rusted/seized rod, totally clogged valve orifices, drain-back channels and locked up in the firm position. Parts in these shocks are quality and robust.  With clean-up, new seals and rod this should be really to go.

Thanks for posting.

Do you know anyone that can re-bush the top mount part of an original shock to look correct?
