tankertoad Posted August 31, 2019 Report Posted August 31, 2019 Ordered a new bayonet probe for my EDM 800 because the #4 died, and assumed the factory was on #3. Open my cowl to find it on #4. Im pretty sure I need the gasket style from JPI, but there are two listed on Spruce (M-113, M-113-3/8)...anyone know which one I need? (IO-360 A1A) - TT
tankertoad Posted August 31, 2019 Author Report Posted August 31, 2019 Also - the M-113 come in either 14mm or 18mm diameter.
carusoam Posted August 31, 2019 Report Posted August 31, 2019 Typically there are two common sizes... The larger one, fits under a spark plug... (less appreciated 50°f variation) The smaller one, fits under the bayonet TC holder... (better location, still a 25°F variation) Check to See if that is what you have to decide from... Also... Some Mooney ship’s gauge CHT sensors are thermistors and not TCs (thermo couples). PP thoughts only, not a mechanic. Best regards, -a- 1
tankertoad Posted September 2, 2019 Author Report Posted September 2, 2019 Thanks ! Fortunately, my factory is working, just need the one going to the JPI. I think the 14mm size is the best guess (18mm under spark plug, 3/8 for Tanis) for what will fit under the factory TC. Cheers!

The thread size is a 3/8”-24. Clarence
