Almost a year after last time I looked into this I’m still a bit confused. Difficult to figure out, but I think I’m on the right track now.
Not easy to find parts manual for the J-model. Manuals claiming to do so always starts with the drawings from the K-model. And if I find drawings from the early J version, they are without any part no.
After a lot of research I think I got it. Look at the green box for the J model. No 4 and 14 are both oil seals. For the K-model no 15 is the oil seal and 14 is a ring above the oil seal to lock the seal in position before the no 13 clip.
And why is no 24 part of the drawing, don’t see the need for a dust seal, or if it can be fitted underneath the no.19 boot ?
Anyhow, I will order parts according to the K-model since it’s an upgrade from the J. All other parts seems to be the same.
Can’t use the photos I took while dismounting the fork. It’s a mess from previous owners. No 9, the valve damper was mounted upside down. No 11 and 12 had swapped placements. The order of the parts at the picture above shuld now be correct.
Was lucky to get hold of a brand new outer tube and a new inner tube. In addition I bought a used inner tube in a good condition. I can therefore replace both of the old inner tubes.
The tube at the picture above, screwed down into the bottom of the outer tube can’t be seen on any drawing. From the L-model and off, the tube is part of the drawings, but an other type tube. From the L models and off, there is a piston ring in nylon mounted between the tube and the spring. I “guess” I don’t have to fit that part into the J/ K fork.
