6. OIL LEAKING

NOTE:
If the gearbox is dismounted without confirming
where the leak is, it must be mounted again to lo-
cate the leak point.
1) Even if the location of the leak can be easily
found by observing the leaking condition, it is nec-
essary to thoroughly remove the oil from the sus-
pected portion and turn the steering wheel from
lock to lock about thirty to forty times with engine
running, then make comparison of the suspected
portion between immediately after and several
hours after this operation.
