Filter Inspection & Cleaning; Oil Change; Belt Adjustment - Ingersoll Rand 2340 Manual Del Usuario

FILTER INSPECTION & CLEANING
1. Unscrew and remove the wing nut (A) securing the filter housing (B)
to its base (C).
2. Remove the filter housing and withdraw the old filter element (D).
Clean the element with a jet of air or vacuum.
3. Replace the filter element and housing, securing it in place with the
wing nut previously removed.

OIL CHANGE

1. Remove the oil drain plug (A) and allow the lubricant to drain into a
suitable container.
2. Replace the oil drain plug.
3. Follow the filling procedures in OPERATION section.

BELT ADJUSTMENT

CHECKING BELT TENSION.
Check belt tension should be occasionally, especially if looseness
is suspected. New belts must also be properly tensioned upon
installation.
TENSIONING BELTS.
Belt tensioning can be achieved by loosening the motor or engine
anchor screws, pushing the motor or engine away from the pump,
and retightening the motor or engine anchor screws. Some units are
equipped with a belt tensioning bolt that, when turned, pulls the
motor or engine away from the pump. Otherwise, the motor can be
easily moved by placing a prying tool beneath it. A commercially
available spreader or other belt tensioning device can also be helpful.
Follow the procedures outlined below to correctly set and measure
belt tension on electric motor and gas engine models including
2340, 2475, and 2545 (with "A" belt type only). Refer to the following
illustration for a visual representation.

1. Lay a straight edge across the top outer surface of the belt drive
from pulley to sheave.
2. At the center of the span, perpendicular to the belt, apply pressure
to the outer surface of the belt with a tension gauge. Force the belt to
the deflection indicated in the BELT TENSION TABLE in the DIAGRAMS
& TABLES section. Compare the reading on the tension gauge to the
table.
Follow the procedures outlined below to correctly set and measure
tension on 7.5 through 30 horsepower models 2545, 7100, 15T and
3000 with "B" and "C" belt types.
1. Measure the span length (t) of the drive.
2. Determine the amount of deflection (in inches) required to measure
deflection force (in pounds) by multiplying the span length (t) by
1/64. For example, a 32" span length multiplied by 1/64 equals 1/2" of
deflection required to measure deflection force.
3. Lay a straight edge across the top outer surface of the belt drive
from pulley to sheave.
4. At the center of the span, perpendicular to the belt, apply pressure
to the outer surface of the belt with a tension gauge. Force the belt to
the predetermined deflection
calculated in step 2. Compare the reading on the tension gauge to the
BELT TENSION TABLE in the DIAGRAMS & TABLES section.
Ensure the pulley and sheave are properly aligned and the motor
anchor screws are adequately retightened prior to restarting the
compressor.
Improper pulley/sheave alignment and belt tension can result
in motor overload, excessive vibration, and premature belt
and/or bearing failure.
To prevent these problems from occurring, ensure the pulley and
sheave are aligned and belt tension is satisfactory after installing new
belts or tensioning existing belts.
