Can you tell mo the cause Of a slight |
grinding noise in the transmission OF |
my cart II is most noticeable in first
and second speeds. 10 u caused by |
worn bearingsG
The grinding noise IL probably due 10
wear IN the gears and not 10 any bear
ing wear. III your clutch has been Ia
the habit OF sticking aud not releasing
completely, due 10 lts being slightly /
out of order, the gears have been spin
ming when the shifts We're made, with
the result that tho gear teeth are bad
ly buried and worn. Nothing will
make more unpleasant grinding noise
than old gears under load. The fact
that you do not notice this noise 50
much IN high is an Indication that IL Is
gear trouble, as you are not driving
through the gears then. There Is no
remedy except replacement Tor worn
gears.
