Subject: Re: Changing Fork oil



|Is  there anobody who can explain the procedure to change the oil in the
|fork of my new (used one, new for me) @ RD04 1991?

Hi Francesco,
it's easy, but the description is difficult because of the english
words. Make the following steps.

-  Buy two O-rings which are under the cover of the fork (see b) ).
-  Buy the two seal slices which are under the screws for draining the oil.
   (see  d) ).
a) Open the screws (Klemmschraube der oberen Gabelbr"ucke) 
   which "fix the cover (Standrohrverschlu"sdeckel)" of the fork
b) Remove the two covers. Eventually you need two new O-rings here.
   I used the old ones but I think the next time I have to change the O-rings
c) Remove the springs
d) Remove the "closure" screw  which is in the low part (at the side) of the fork.
   Here you should use two new seal slices.
e) Pump carefully with the fork the rest of the oil out of the fork.
   Here it is useful two have a second person at hand which will catch the
   oil which comes out of the fork.
f) Mount the "closure" screw using a new seal slice.
g) Refill the fork with new oil, for the RD04 it's 635ccm for every 
   fork pipe if you have the original springs.
h) Fix the rest. The torque for the cover is 23Nm the torque for the 
   screws which "fix the cover" is 35Nm.



|I know it has never be done from 1991. 
|It is time, is it? or not?

I think it can't be wrong. I did this last year with a 91 RD04 (first driven
92) and the old oil looks horrible it was a very dirty mixture of water
and oil.

Hope it helps,
