Your Pinion Gears
On Sept/Oct 79
pinion gears on the Mark V that drive the saw table up and down
are made of copper and iron. Running on steel back teeth, they need
no lubricant. However, after some use, sawdust builds up and collects
in the rack and pinion teeth. This can cause the pinion gears to
strip off these teeth – so the sawdust has to be cleaned out periodically.
To clean the rack and pinions, use a stiff bristle brush. Removing
the pinions to clean is easy:
remove the saw table assembly from the carriage. Then remove the
table height locking handles, washer, and lever assembly. Slide
the square pinion shaft out the rear of the carriage and each pinion
will slide out, one to the front and one to the rear. Don’t worry
about getting them mixed; they’re identical.
reassemble, just reverse the procedure. This whole cleaning process
takes 5 minutes and should be done whenever stiffness develops in
raising or lowering the table – or you may strip off the teeth!
