The type of gear reduction system which may be classified as either inboard or outboard, is the:
Planetary final drives used on modern heavy equipment and trucks are typically _____________.
Typically, single reduction final drives use a splash system of lubrication.
Before you begin to remove a final drive assembly off of a piece of equipment, you should:
Misalignment of gears in any type of drive system will generally cause:
Mechanic A says that the manufacturers recommendation is that bent axles can often be straightened and reused. Mechanic B says that, if equipped, the oil pump, filter and galleries should be serviced thoroughly when the differential or final drive is repaired. Who is right?
The gears and bearings should be installed dry. They will receive adequate lubrication when you fill the housing.
Inboard planetary drives are easily serviced without requiring drive sprocket removal.
One advantage to a planetary final drive is:
What drives the sun gear on a hydrostatic type final drive?
An advantage of double reduction final drives over single reduction final drives is:
Excessive wear on crawler final drive bearings could be caused by:
In planetary final drive, the ring gear is the:
Final drive seal leakage may be caused by:
Why is it necessary to change oil in a final drive assembly?
In a planetary final drive, the sun gear is the:
Proper final drive servicing, at the correct intervals is not necessary to prevent excessive wear and damage as long as the operator uses the machine correctly.
Before you begin any final drive work, you should always.
Seals in final drives must only be replaced if they are damaged or do not look like they will perform up to standards.
Single reduction spur gears are lubricated by a pressure pump driven from the engine.
In a planetary final drive:
Mechanic A says that outboard planetaries are most common because they are the most convenient to service. Mechanic B says that in order to service an outboard planetary you must first jack up the machine and remove the tires. Who is right?
Planetary gears have an advantage over other types of gears in that:
In a chain drive system attached to a final drive, a change in driven speed of the wheels can be accomplished by:
In a planetary gear set if the ring is held, the carrier is the drive and the sun is driven the result is:
