Koellmann Gearbox Rebuild, Repair, and Emergency Services
Once your Koellmann gearbox arrives at our
facility we disassemble, clean, inspect and measure all
gears and shafts and determine if your Koellmann gears and
shafts are qualified to be repaired. If the Koellmann gears
and shafts are not repairable, we have the
capabilities and expertise to manufacture all new Koellmann
gears and shafts such as Helical, Double Helical,
Herringbone, Split Herring bone, Bevel, Spiral Bevel, Spur
Gears, Ring Gears, Eternal Ring Gears, Rack & Pinion, Worm
Gears, Double Enveloping Worm Gears, Hypoid Gears, Screw
Gears, Plus More! Once your
Koellmann gearbox is repaired we then do a six hour
test run for overheating, vibration, and leaking to ensure
our 24 Month Guarantee. National Gear Box Repair can do all
of these repairs and rebuilds at a considerable amount of
saving rather than buying a new Koellmann gearbox.
