Gear Box Spares

Upon receipt at Leading Edge, the gearbox is identified, booked, photographed and couplings or other attachments are removed. General condition of the drive is noted for our report, and end float and backlash are measured and recorded.

The gearbox is completely stripped, photographed, inspected and condition recorded. All bearing details are recorded, and compared with OEM supply. Upon client acceptance of our quotation the gearbox then moves to the next stage of refurbishment.

Gear and Bearing Removal

With the help of hydraulic press and bearing puller, all bearings & gears should be dismantle with proper way. Our in-house facility give us safer, quicker & easier way of dismantle of gear box parts

After a long service life, gearbox housings can be expected to be outside manufacturer's tolerances. For that reason, Our Engineers conduct a complete dimensional check on the gearbox housing as follows.

 Concentricity and parallelism of bores
 Ovality of bores
 Horizontal and vertical positioning of bores
 Mounting face flatness on all planes
 Joint Face Flatness

We proud to say that "We do it better" than other so-called gearbox refurbishment companies

At LEADING EDGE, we employ several methods of non-destructive testing of components. Gears, keys and shafts undergo the more sophisticated method of ULTRASONIC testing, In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal cracks. It is another example of the way that LEADING EDGE goes that extra distance to give you the greatest chance of a long service life in your component once refurbished by us.

Damaged shafts can be machined, metal sprayed and ground back to required diameter and surface finish. We can retain an OEM specification or improve hardness and surface finish to provide longer service life. We don't simply opt for the simple run of the mill seal for your application. We spend the time to check the application with seal experts, and ensure that the brand, style, design and material used in the seal is the most appropriate for the application. Near enough just isn't good enough. With expert attention to the seal rubbing surface. DCL Group can assure you of the best possible chance of long service life without the dreaded oil leakage.

All shafts are checked for dimensional accuracy, concentricity, ovality and straightness before being reused. This, when added to the crack detection, means that as our customer, you can be confident that these components are not being reused unless they are at least up to, if not exceeding, OEM specification for that particular application.

Gears and shafts are re-assembled with new bearings fitted, backlash and end float are checked against OEM and bearing manufacturers specifications, and the results are recorded for your report.
