Expansion tank fitting
in 912 / 914 Technical Questions
3 hours ago
The following pertains to my Rotax 914 UL -2, suffix – 01, serial number 10001107.
I am attempting to track down a part not depicted on the Rotax expanded parts diagrams. The water cooling system EXPANSION TANK has a bolt with viewport on the side of the top half of the tank.
I would like to replace this with a
#1 adapter fitting, or
#2 a solid bolt that I can drill out and thread, or
#3 purchase a identical viewport nut that was supplied on the expansion tank and modify it.
With a goal of creating a fitting that would hold a temperature sensor in the expansion tank, identical to the two factory coolant temperature sensors on the cylinders ( listed as part number 965531).
**Can you tell me where I can source a adapter to accomplish this? I have tried a M12 and a M14 x 1.5 bolts but neither would fit the hole / threads in the tank.
**Can you tell me what the size and the female threads would be for this part to fit within fitting on the tank?
**Can you tell me what the male threads are on the temperature sensor part number 965531?
Thank you
