Modifying the Bearing Cap
3.7.1
Drilling the Bearing Cap
Hold the bearing cap steady for drilling in a soft jawed vise clamp.
NOTE :
Do not apply too much clamping pressure with the
vise. The bearing cap may be damaged.
Using a pedestal drill, drill a 6.35mm [¼’’] hole through the bearing
cap where the seal housing tube hole has been marked.
(Fig.9.)
Figure 9.
Remove the bearing cap from the vise, turn it upside down, and
re-clamp it in the vise.
The drilled hole must be chamfered approximately 3mm [1/8”] to
remove any sharp edges that may chip-off and fall into the housing.
