Gear boxes are to be rigidly mounted so as to minimize the effect of fluctuating or heavy loads. Always check the alignment after bolting down. After installation and alignment has taken place, properly locate the gear unit by means of dowels at appropriate locations preferably in diagonal direction.

The use of flexible couplings (Love joy / Gear coupling flanges with rubber bushes / tyre couplings) are very important for the improved performance of the gear box. The couplings are to be lined up to avoid the misalignment of angularity and eccentricity.

The MM Gears Speed Reducer lubrication system is self contained positive and automatic at all speeds of operation and in either direction of rotation. Adaptable units are provided with breather, oil level and drain plugs and it must be ensured that these are correctly positioned as shown on the accompanying diagram. Other units incorporate a dipstick for oil level checking, an oil filler-cum-ventilator and drain plugs. Their locations are shown below.

MM Gears Speed Reducer units are supplied without oil and must be filled with the correct grade of lubricant to the correct level. It is important to ensure that the correct oil level is not exceeded as over filling causes oil churning which resulting in overheating and leakage.
