Tapping Lubrication Points - Lincoln Quicklub Maintenance Manual

Tapping Lubrication Ports (if necessary)
It is sometimes necessary to re-tap a lubrication port due to port damage or drive type fitting removal.
Tapping oil should be used to ease the tapping process. Make sure that all metal filings are removed
from the port prior to installing the fitting. Always check with the customer before altering the machine.

Zerk-Lock fittings (part# 270784) can be used for drive type fittings, but it is recommended that the
fittings be removed and tapped to install a more reliable fitting.
Spin Drive (thread forming) fittings have special tapered drive heads for fast production line installation
in untapped holes to save tapping cost. Spinning into the hole with a power wrench provides the most
effective installation.
Drive type fittings are designed for fast production line installation in untapped holes. One method of
removing drive type fittings is to use a small easy out tool with a drill and place the easy out tool into the
ball check of the grease fitting and wear out the drive type fitting until it is able to be removed from the
machine.
Loctite can be used on the threads of fittings to ensure that fittings do not vibrate loose.
