General Electric LM6000 T4.8 Thermocouple & Harnesses

	Weston part No: 862-7-19C
	GE part No equivalent: 1696M81P13
	Specified in GE Service bulletin 122

Weston Aerospace is a GE Aircraft Engines approved manufacturer of the T4.8 TIT thermocouple probe for all variants of the LM6000 series of engines.

The latest probe, introduced by GE Service Bulletin 122, is the same as used on the high thrust CF6-80E1 aero engine.

The Weston LM6000 T4.8 probe features a thermocouple sheath manufactured from DSR 142 (a high temperature blade alloy) with an oxidation resistant coating, providing superior probe life and eliminating risk of structural failures.

All of Weston’s LM probes address failure modes inherent in previous standards. For example, broken terminals, loss of IR and spring relaxation.

The terminals have a 400% overtorque capability (to 120 lb.in). The threaded parts are made from an anti-galling material to prevent seizure of the harness nuts, and have a high thread stripping resistance.

The compound concentric spring design prevents spring relaxation & the thermocouple element sheath provides high temperature erosion resistance.

Weston can also offer an aftermarket alternative to the GE T4.8 thermocouple harness. As with the thermocouple probe, these parts have been designed to overcome failures experienced by some operators. The harness has a high integrity terminal tag design, which is rated up to 1100°F.

Both of these items are available to all operators and overhaulers of LM6000 engines and will provide cost benefits due to increased reliability and lower life-cycle cost.
