Andrews Products is in the 26th year of making after market transmission
gears for H/D motorcycles. We are the original manufacturer of close ratio
gears starting with 2.44 ratio first gears for big twin 4 speed gear boxes
in 1972. The best quality gears and shafts for 4 or 5 speed big twins or
Sportsters continues to be Andrews.
Our commitment to the after market industry has been underscored with
seven figure investments in machinery and manufacturing technology. Pictures
of some of these new machines are shown below. Our goal as a manufacturer is
to maintain the highest level of quality and service for all of our
customers.

The first step for some of our gears and cams is on this
Mazak Multiplex twin spindle machining center. Cut steel slugs are
automatically loaded from a robot gantry and machined complete in one setup.
Finished parts are then automatically unloaded. This machine can operate
unattended for hours at a time.

After parts have been machined on lathes, secondary
operations such as keyways, drives slots and lugs are cut with CNC vertical
machining centers as with this Matsuura automatic pallet changer. Final
operations on these machines include a self contained computerized
inspection of slots and lugs. Pallet changes take 5 seconds.

Additional steps in gear manufacture require cutting teeth
on this Mitsubishi GS15 CNC gear shaper. A number of other computer
controlled gear machines are also used by Andrews Products to produce gear
teeth for a variety of transmission gears.

Our Toyoda GC32 CNC angle head grinder is shown grinding a
Sportster cam gear thrust face and bearing diameter. CNC angle head machines
can grind multiple diameters in one setup and hold tolerances of .0003
inches (.0076mm) on a diameter. Grinding is one of the last steps in gear or
cam manufacture. |
