2. Proceeding fronr below, rernove
the fuel
tonk sheet guord
ond the guord
of the cooling
woter pipes.
3. Disconnect the pipe
of the clutclr hydroulic
line from the clutch releose hose brocket.
4. Screw out droin plugs
to droin fuel from
the fuel tonk ond ot the some time disconnect
the fuel hose from
the fuel pump.
After com-
pleting the droining, reinstoll the droin plugs
(screws) with their seoling rings.
Disconnect the tronsverse hose connecting
both sections of the fuel tonk ond stop the
open
pipes with rrubber
plugs (to prevent
the remoin-
ing fuel spilling over your
honds ond clothes
when lifting
the tonk owoy).
5. Disconnect the geor
shift link ond the
speedometer drive from the georbox -
see Chop-
ter 4.1, por.9.
6. Detoch cobles from the hond broke rocker
ond pull
them out from under the cor -
see
Chopter 9.8. 7. Droin the cooling system -
see Chopter
-15.13.
Disconnect the moin woter line in
the
rniddle of the cor. Disconnect the pipes
from
the engine (from
the hose of the thermostot
ond the pump
connecting hose) ond remove
the
pipes -
see Chopter 11.4.
8. Disconnect the hose of the fuel
tonk from
the fuel filling pipe, ond, in the upper port,
the
hose of the fuel filling line vent pipe.
9. Sever the electric connection of the fuel
level gouge
floot system under tlre right-hond
I eor seot.
10. Use o
iock to support
tl're georbox
ond
loosen tlre connection of the georbox
cross
beorer with the bodywork.
11. Loosen the copscrews fostening the fuel
tonk to the bodywork ond lower the
iock to tip
the power
pock.
Retoin the fuel tonk while ne-
nroving the copscrews, move the tonk bock-
words ond down, tip it down ond forword, ond
remove it in
this direction. 12. Should
the pipes
of the broke system ob-
struct tlre removol of the tonk, disconnet them
from the finol drive ond from broke hose brock-
ets.
Refitting Fuel Tqnk in Cor
Reverse the procedure
of the tonk removol.
Fill the cooling system with the recommended
coolont ond bleed it, odjust the hond-broke ond
the occelerotor cobles. Bleed the clutch hy-
droulic line
ond olso the reor wheel brokes if
the hydroulic broke line hos
been disconnected.
