like2strokeansmoke Posted May 21, 2009 Share Posted May 21, 2009 Hi Guys I've just stripped the forks on my '78 DT400 because they were stiff and the head bearings needed replacing (- and I'm still having to adjust the 'All Balls' replacement roller kit as the taller top bearing [as original balls only 1/4"], means the triple clamp fouls the bearing locknut). When I disassembled and removed the damper internals the parts discribed as ; No 13 "Cylinder comp" (on the parts diagram) had part No 12 - "Piston" fitted, AFTER the drilled aluminiumc cone, onto the shaft were it was free to slide up and down the "Cylinder Comp". I find I'm unable to assemble the unit, as per the drawing, as the aluminium cone piece, at the end of the "Cylinder Comp" ,has a bigger diameter than the inside of the stanction. Therefore the internal circlip (part No 11) can not be fitted?!! Is the Diagram correct?? The Aluminium cone had been assembled AFTER the internal circlip was fitted when I opened it up.

like2strokeansmoke Posted May 27, 2009 Author Share Posted May 27, 2009 The forks are back together the way they were and I have to conclude the Yamaha diagram is wrong (surprisingly). Link to comment Share on other sites More sharing options...

Cheers, I'm sure yours will be put together the same way, it's impossible not too! The bike's handling much better and I take it for a blast every sunny day at the moment - and today was sunny!
