Howdy All,
This is a follow up on a 3 gauge cluster installed on BX 25. The task was to mount the temperature probe for a HST temperature sensor.
I obtained a new rear PTO cover located at the HST dipstick.
A 1/8 NPT hole was tapped into the aluminum housing as shown. Diesel fuel was used as the lubricant while tapping it, this was a recommendation from an other ol' timer for better thread resolution. maintaining a clean tap is also essential.
The probe threads and case threads were both coated with TFE paste thread sealant and installed.
The probe itself was coated with some Permatex high temp RTV for some protection. The sensor wiring was also coated with the RTV and "glued" into the slot along the dipstick as shown.
The PTO cover was installed after sealing it with a Permatex Anaerobic RTV with spray on activator.
The wiring was fun along an existing wire loom up to the engine are and my new gauges.
A HST service was done and after 24 hours new UDT2 was added and I was on my way.
Interestingly the temperature was running during heavy MMM cutting was under 140 degrees. The see how high it would go I ran in rabbit WOT up and down several steep hills and got it up to 185.
I haven't used it yet in front end or backhoe mode, so no info there.
It sure is nice knowing this parameter and also very nice to watch it come down during cool down after working.
The area seems quite safe and relatively protected for the probe.
Please excuse the sloppy RTVing, There are 2 things I am really crappy at its RTVing and caulking!!
Almost forgot the sensor/gauge combo is a automotive transmission temperature gauge set from summit auto for 320 degree range.
