SPECIAL ADJUSTMENTS
The useful life of the bushings in your router carriage will depend upon how well the rods they slide on
are kept clean. If any type of lubricant is used on the rods, the bushings will be short-lived.
When the bushings do wear to the point where the carriage no longer makes an acceptable mortise, you
may (1) replace the bushings yourself, (2) have them replaced at a machine shop, or (3) purchase a rebuilt
router carriage from the factory. If you choose to install new bushings into the carriage yourself, you
will need a press and two line reamers, one 1/2” and one 5/8”. To replace, press or drive the old bush
-
ing out FROM THE OPPOSITE END and press the new bushings in, taking care not to damage them.
Once inserted, line ream each pair of bushings to fit the matching slide rod. Since most door shops do not
normally have presses and line reamers, we would suggest you contact the factory for a replacement car
-
riage, as the cost will, as a rule, not exceed the cost of taking your router carriage to a machine shop. Plus
you save the down time.
