All the gears on one shaft are meshed with all the gears on the other shaft all the time

What is a constant mesh transmission

100

Final drive ratio on a shaft driven MC is calculated by dividing the number of teeth on these 2 gears.

What are the ring gear divided

by the pinion gear

100

Filtering of the molecules in oil is done during this process.

What is refining.

100

This rolling element bearing supports radial loads and light axial loads in both directions.


What is a Ball bearing?

100

This must be done to foam and gauze air filters to make them effective


What is oil them?

200

Can be used in place of a slider gear.

What is a dog ring

200

The most common type of chain used for final drives


What is a single row chain

200

25% of a typical quart of oil consists of these

What are additives

200

Supports axial loads, provides spacing and controls end play.


What is a shim.

200

This must be done to carburetors if the temperature drops low enough.


What is jet them richer?

300

Power enters on one axis and leaves on the same axis

What is a direct drive transmission?

300

The type of belt used for final drives

300

Viscosity is rated by this organization

SAE

300

Supports radial loads and axial loads in one direction, usually used in pairs

300

The two test methods for rating fuel


What are research and motor?

400

The shift mechanism is moved by this.

What is the shift linkage?

400

This type of gear is used to turn power 90 degrees

What is a bevel gear?

400

A dry Sump lubrication system requires oil pumps to handle these two functions.

What are feed and scavenge

400

These bearings support high loads but require constant lubrication.


What are bushings & precision inserts?

400

The “anti-knock index” or pump octane rating of a fuel is calculated by what formula?


What is (R+M)/2?

500

Fixed, Free Wheeler, and Slider

500

Additives are added to oil base stock to accomplish this.

What is to enhance base

oils for specific applications?

500

These very low friction rolling element bearings support axial loads only.
