Fenner Taper Lock Pulleys

External Since: Jul 12, 2007 Posts: 11

I am fitting 2 Fenner taper lock pulleys to a motor shaft and a
saildrive shaft and I have the same problem on both of them. The grub
screw side on the pulley is on the inside of the pulley - so when
pushed home on the shafts the motor/saildrive prevents access with an
allen key to tighten them up. The best I seem to be able to do is to
tighten up the taper lock off the shaft until a tight interference fit
is achieved, then slide on the pulley and secure in place with a
machine screw into the shaft - probably as a bored pulley would
fitted.

I had a sudden flash that perhaps I could tighten up the grub screws
from the other end of the taper locks, but there is insufficient
access to get the allen key in.

Any other ideas out there?

CS,

No, you can't remove that much material.

What is it about the sheaves that you can't turn it over?
If you are that short of shaft length, move something.
