SCAVENGE PUMP GROUP 4M5909 - Caterpillar

*Direction of rotation (as viewed from flywheel end):SAE Standard Rotation - CounterclockwiseSAE Opposite Rotation - ClockwiseNote: Front end of engine is opposite the flywheel end. Left side and right side of engine are as seen from flywheel end. No. 1 cylinder is the front cylinder on the right side. No. 2 cylinder is the front cylinder on the left side.Optional Uses
There are available in the Caterpillar parts system, some optional type K thermocouples: 8T-0933 8T-0934 8T-0935 8T-0936 8T-0458 Type K Thermocouples . These thermocouples are used with the following Probe Seal Adapters: except for the 8T-0458 Bead Type Thermocouple .

Probe lengths are: 8T-0933 Thermocouple Probe , 25.4 mm (1.00 inch) long 8T-0934 Thermocouple Probe , 38.1 mm (1.50 inch) long 8T-0935 Thermocouple Probe , 63.5 mm (2.50 inch) long 8T-0936 Thermocouple Probe , 88.9 mm (3.50 inch) longThese thermocouples will plug into the inputs of the 4C-6090 Multichannel Temperature Selector , but are not designed for exhaust temperature measurements. For exhaust temperature measurements, use 6V-9055 Exhaust Thermocouple .An optional use of this instrument would be checking temperatures on a marine engine using the above mentioned thermocouples and probe seal adapters. Any engine or transmission temperature may be measured using the previously mentioned components where a digital readout would make the job easier for the serviceman.Thermocouple Extension Leads
The leads on the 8T-0458 8T-0933 8T-0934 8T-0935 8T-0936 Thermocouple Probes are 1219 mm (48.0 inch) long. If lead is not long enough for the application, an extension lead must be made from 7X-7481 Thermocouple Wire , a 4C-6095 Mini Plug and a 4C-9030 Mini Jack . Length
