Broken line to Oil Temperature Probe, Repairable?
I have a Cessna 172M with o-320-e2d engine.
The metal line connecting the gage to the Oil Temperature Probe broke. The probe is inside the Oil pressure housing on the back of engine. Can the line be reattached to the 2 inch long Copper probe by welding? I believe the gage works under capillary effect. Are there any Cessna approved replacements for the gage, line and probe or do I have to replace with the Cessna OEM part? A Cessna dealer told me the gage is either made by Stewart/Warner or Rodchester and costs around $300-400. Replacement Temperature gage and probes for homebuilts seem to cost around $90. TIA, John |

Bend over, lube up. I suspect a bone-fide Cessna part would be in
order, unless there's and STC for the electric type sender used in Pipers. -Cory rkane33 wrote: : I have a Cessna 172M with o-320-e2d engine. : The metal line connecting the gage to the Oil Temperature Probe broke.

they are repairable. Remove guage and capillary tube and nut that attaches the
bulb to the engine. Send the whole mess out for repair. Not sure who else does it but I just had one repaired by Air Parts of Lockhaven. You can find them in the trade a plane. They will attach a new tube to your gauge and recalibrate it. Last one I had done cost me about 150. Mark |
