Engine Air Cleaner; Figure 5.6 Air Cleaner, Dry Element - Carrier RG2059 Series Operation And Service

The poly V-belt is driven by a sheave on the engine crankshaft. Its two functions are to:
• drive the radiator fan
• drive the water pump
To replace the poly V-belt, perform the following steps:
1. Using the proper size socket, slowly rotate the crank on the crank pulley nut. At the same time, use a flat, blunt
object to guide the belt off the crank pulley towards radiator. Be careful not to damage grooves on the pulley.
2. Replace the poly V-Belt by positioning the belt on the water pump pulley, and while rotating the engine (as in
step a.), use a flat, blunt object to guide the belt onto the crank pulley. Be careful not to damage grooves on
the pulley or belt.

Engine Air Cleaner

The dry element engine air cleaner uses a dry element filter (see
bath air cleaner option uses an oil cup instead of the standard dry element filter (see
The engine air cleaner should be inspected regularly for leaks, (see
can seriously affect the performance and life of the engine. The air cleaner is designed to effectively remove con-
taminants from the air stream entering the engine. An excessive accumulation of contaminants in the air cleaner
will impair its operation. Therefore, a service schedule must be set up and followed.
1. Check all connections for mechanical tightness. Be sure the air cleaner outlet pipe is not fractured.
2. In case of leakage, if adjustment does not correct the problem, replace necessary parts or gaskets. Swollen
or distorted gaskets must always be replaced.
Air Filter Indicator
The air filter indicator, used with the dry element filter, is mounted on the air filter body. Its function is to indicate
when the air cleaner dry element needs to be replaced. In operation: When a plugged air cleaner decreases intake
manifold pressure to 500 mm (20") WG, the indicator moves to the red line. The air cleaner element should be
replaced and the indicator reset by pressing the reset button.
Air Cleaner, Dry Element Service Procedure
1. Stop the engine and open the cap clamps (see
2. Remove the air filter element from the air cleaner body.
3. Install the new element, secure the bottom cap with the cap clamps.
When reassembling the Air Cleaner, make sure the Clamp Bolt faces out, away from the fuel filter.
If the Clamp Bolt is assembled facing in, it can contact the fuel filter and cause excessive wear.
