I'm disassembling the '72 911 front uprights for cleaning, new rotors, etc., before installing on my 914.
I went to pull the strut out of the upright and it appears the upright is the outer part of the strut. The upright is filled with oil. Were the early shocks not self-contained like the ones today? Can I replace the lost oil (about 1 teaspoon worth)? What kind of oil? The shock has very good resistance and doesn't seem worn. Attached image(s)

I've never seen a Koni that used the strut tube as part of the damper, but I don't claim to have seen them all, and if Eric says they exist, I'll believe him.
However - that looks like an original Boge to me. Pulled those out of two factory /6's. It's hydraulic oil and it smells _bad_ ... So yes - some of the early Boge struts as used on 914/6 and evidently some 911 ran directly in the strut tube. Probably something like hydraulic jack oil or hydraulic cylinder oil (available at Tractor Supply, for instance...) would be compatible. MMO or ATF would probably compatible ;-)... But I don't think I'd trust the seals on a 40-year-old damper no matter how well it seems to cycle by hand. It could work today and fail tomorrow. And Boges were never the performance damper - they were the entry-level part. |
