True, the throttle cable with outer sheath on the rear part can get
old/sticky/worn etc.
But that's not what I find will really help the throttle work smoothly
again. ( sure ..lube that rear part ..where the inner cable goes through the
outer cable or sheath )
'short version' is ...........remove forward cable from white tube in the
body of the van ...clean and lube while fitting throttle cable back into
that tube.
detailed longer version :
Remove the plastic cover under the front floor that covers the throttle bell
crank.
undo that barrel nut there - 8mm wrench.
Go to the middle of the van , underneath ..
undo a 10mm nut and bolt there.
and pull the forwrad part of the throttle cable out the white plastic tube
going forward.
Blow that tube out with compressed air if you can.
spray wd-40 into the tube, and blow that forward into the tube...
idea being to get that tube clean and free of moistuer, crud etc.
then feed the front part of the t-cable back into that tube...spraying a
good lube on the cable as you do.
Lube the bell crank area really well.
If you find a gab at the aft end of the white tube ...like some exposed
innner cable there, the white tube has slid back a little in the van.
Pull the white tub aftward so that gap is closed.
Up front, about 6 inches aft of the bell crank area .....clamp the white tub
so it can't slide . ...there's metal bracket or something to clamp it to,
like with a small # 4 size american hose clamp.
connect the 10 mm nut and bolt back together.
Adjust the cable length with the 8mm barrel clamp thingey at the forward end
of the cable.
Check that full throttle is achieved with gas pedal flat on the floor.
make sure there's some slack to it gets fully back to idle.
put the plastic cover on last ....where the whitel tube goes through it ..I
just cut a little slit there so I can put the plastic cover on last, after
I'm totally satisfied with how the whole thing works.
The 4 little screws that hold that cover like to fall and dissapear
somewhere, so careful with that.
'all' vanaogns almost need this service.
....clean and lube white forward throttle cable tube in the body of the van.
