Decided to rebuild the Fox shocks that I had on the Husqvarna 360 as they looked like they were pretty tired and the measurements showed a lot of sag. I didn’t have a service kit for them so it was a bit of a rough and ready job. For the longer term, I’ll make a spring compressor, but for this job it was out with the rachet straps and slip off the bottom collet. There is a preload adjuster on these Fox (non-air) shocks and noticed I could have tried them with increased compression.
Fox Shocks had a bit too much sag, so there would be very little suspension travel on the rear of the bike.
They are relatively easy to strip and a relatively straight forward design. The only challenge is getting out the lower circlip which is about 40mm down inside the bottom tube and ideally need some long nose internal circlip pliers. There was oil left in the shock but not a lot (<50ml) and expect 60-70ml in the shock. Didn’t change any seals but ideally would want to this going forward. There is an air top for the shocks, where you’d normally put some form of inert gas, lets say 50 psi as air will heat up with work on the track. However, can probably get away with this for now.
The oil looked a bit original and maybe missing some volume
Shock back together with some fiddling, again with the lower circlip and the compressing the spring. It didn’t seem quite right when back together but the proof will be the using. Doing a proper service with seals etc might be the better plan. But given they were £50 shocks (from Telford) and period items, I’m happy to experiment with them Did some other work on the bike to get ready for the North Devon meeting coming up, but have worked out the starting technique for the bike, which has a Mikuni carb. All of the Huskies flood easily and then can be buggers to start (you need to take the plug out and given them dry) and the Automatic isn’t an exception.
I’m also becoming more of a fan of the looks of the 360 Automatic despite it having a large enduro tank (which has its uses if I ever do another Gentle One). The 1976 models are lower than the 1975 models it seems and the frame and shock length different.
