When to change the oil in a gearbox?
Gear oil changes as needed are critical during the first few weeks or months of operation of gear cases. Rather than setting arbitrary change intervals, manufacturers should regularly monitor by oil analysis the condition of the oil to determine stability of the lubricant.
What kind of lubrication do you use on a spur gearbox?
Oil splash lubrication is often used for helical, spur, and bevel gearboxes. This method is also referred to as an oil bath, because it uses a reservoir is filled (or partially filled) with oil. As the gears rotate, they dip into this oil bath and splash the oil onto the other gears and bearings.
How is forced oil circulation lubricated in gears?
Forced oil circulation lubrication applies lubricant to the contact portion of the teeth by means of an oil pump. There are drop, spray and oil mist methods of application. – Drop Method. An oil pump is used to suck-up the lubricant and then directly drop it on the contact portion of the gears via a delivery pipe.
What causes an oil leak at the front of the gearbox?
The oil seal where the speedometer cable enters the gearbox sometimes fails. Fit a new one (See Fitting a new speedometer cable). A leak at the front end of the gearbox may come from damaged seals in either the engine or the gearbox, or a gasket between the gearbox and the clutch bell housing.

What causes the oil in a gearbox to foam?
• Rapid fluctuations in operating temperatures, high speeds, and heavy loads. • Any operating environment that causes condensation inside the gear case or oil reservoir, resulting in formation of sludge and causing the gear oil to foam. • Operation in moist or dusty environments, or where chemical fumes are present.
Where to put oil sight glass on gearbox?
Tenth, install an “oil sight glass” to the gearbox drain port at the bottom of the reservoir or with an elbow for drain ports located on the side of the gear equipment. Any statement regarding the service life of gear oils should include information regarding operating, environmental, and mechanical conditions of the equipment.
