Repair Procedure: 

1.Fits:

• Checking fits and leakage from the fits if any. If leakage, need to repair with oil seals/sealant and required machining.

2.Shafting:

• Repair may be made by plating and grinding, or machining and sleeving.
• Will be straight and finished in accordance with tolerances and finish specifications as indicated on appropriate drawings.
• New shafting provided will match the specifications and dimensions of the original part as per customer print.
• Exposed threads, shaft ends and couplings will be protected with an anti-rust protection coating prior to shipping your Gear Box.

3.Gearing:

• Will be dimensionally inspected to customer prints, manufacturers’ prints, or reverse engineered.
• New gearing provided will meet or exceed the specifications and dimensions of the original parts as per customer print.

4.Gearbox Housing, Cases:

• All bolts, studs, pipe plugs, and other fittings will be removed and the holes re-tapped as necessary.
• Bolts, studs, and pipe fittings may be reused if in good condition.
• Replacement bolts, studs, and pipe fittings will be of equivalent grade and material unless otherwise specified.
• Split housing jointing surfaces will be machined / ground as necessary.

5.Assembly and Test Procedures:

• All seals, shims, and gaskets will be replaced
• All bearings will be replaced
• All hardware will be reused or replaced depending upon condition.
• All repaired and overhauled units will be run tested to check contact patterns, clearances, backlash, and freedom of movement.
• When pressure lubricated units are involved, we will pressure test the unit when applicable.

6.Painting and Identification:

All speed reducers will have:

• Exterior surfaces cleaned of all loose scale and rust.
• Entire Housing surfaces cleaned of all dirt and oil.

8.Test Run Procedure:

• Firmly mount gearbox to be tested to run test stand.
• Fill the unit with lubrication
• Attach the oil pumping station to the unit if required.
• Hook up all run test equipment.
• Check and note temperature.
• Start test motor and set rpm to the gearbox requirements.
• Check all sealed areas for any oil leakage.
• Gearbox bearing temperature will be checked and noted at several intervals during testing.
• Vibration and other nondestructive testing per customer requirements are available

9.Shipment:

• All openings are properly protected with plugs or cover.
• All units are shipped dry from our factory. The unit shall be marked to indicate that lubricant must be added prior to start of operation
