COOLER GP-FLTR BASE & ENG OIL 2W2660 - Caterpillar

12 kPa (0 to 50 inches of water) and are accurate within .3 kPa ( 1.0 inches of water).
The 6V3150 Gauge does not include a tachometer to measure speed (R/MIN). However, it is made to provide storage space for the 6V2100 Multitach, 5P7360 Tachometer Drive Generator, 5P7362 Signal Cable and 5P7366 Power Cable (parts of 6V3121 Multitach Group). These four components, when used with the 6V3150 Group, provide the same basic functions as the former 4S6553 "Boost Kit" at a much lower cost.
The advantage of a separate tachometer is that it can be used on other jobs when it is not needed in the 6V3150 Group.
Characteristics of the 6V3150 Engine Pressure Group:
1. It weighs 2.7 Kg (6 lb) less, without 6V2100 Multitach, than the former 4S6553 Group.2. It comes in a green polyethylene case (plastic) to provide a cost and weight advantage and does not scratch or permanently dent.3. It has an anodized aluminum panel.4. It uses dual scale gauges: inches of water or psi and kPa.5. It is one of the first of a new series of Caterpillar Diagnostic Tools. This family is easily identified by a green polyethylene case with black panels and white printing.6. It has enough space for the storage of the new 6V2100 Multitach (part of 6V3121 Multitach Group) to give a "boost kit" assembled of modular tools.
Illustration 2. The 6V3150 Engine Pressure Group has storage space for the 6V3121 Multitach Group. 1. Weight: 5.0 Kg (11 lb), without 6V2100 Multitach.2. Size: 39 mm x 311 mm x 101 mm (15.5" x 12.25" x 5.50").3. Gauge Accuracies Over Specified Operating Temperature Range: 4" diameter differential: 2% of full scale
2 1/2" diameter single port - SAE Grade "A" (2%-1%-2%)
4. Operating Temperature Range: 4" diameter differential gauge: -1.1 to 60°C(30 to 140°F)
2 1/2" diameter single port: -18 to 71.1°C(0 to 160°F)
5. Overrange Pressures: 4" diameter differential gauges: 15 psi
2 1/2" diameter single port gauges - pressures above full scale destroy gauge accuracy
6. Pressure Media: 4" diameter differential gauges - clean air and gases only, no fluids
2 1/2" diameter single port gauges - air, oil, water, antifreeze, diesel fuel
7. Operating Position: 4" diameter differential gauges - no effect on accuracy if pointer is mechanically adjusted to zero.
2 1/2" diameter single port gauges - no effect on accuracy
The uses of the different gauges in the 6V3150 Engine Pressure Group are listed below.
The 5P6579 Differential Gauge, 4" diameter, is used to measure:
* Crankcase Pressure* Air Inlet Restriction* Exhaust Restriction* Gas Pressure for Gas EnginesThe 6V4016 Gauge (0 to 160 psi), single port, is used to measure:
* Oil Pressure* Air Compressor Cut-in and Cut-out ReadingsThe 6V4017 Gauge (-15 to +60 psi), single port, is used to measure:
* Inlet Manifold Pressure on Turbocharged Engines* Manifold Vacuum on Natural Gas and Gasoline Engines* Power Balancing of Twin Engines in a Natural Gas or Diesel ApplicationThe 6V4018 Gauge (0 to 60 psi), single port, is used to measure:
* Fuel Pressure* Inlet Manifold Pressure on Turbocharged Engines* Cooling System PressureThese uses
