B Hydraulics ?

I also would like any recommendations for flushing out the transmission/differential/PTO cavity prior to filling with fresh oil. The lube that's in there is SAE 85/90 that I put in years ago. I don't think Dad ever replaced that lube so it's been done only once since the tractor was new. I plan to use Amalie "All-Trac 245" combination hydraulic/transmission fluid - SAE 10W-20 as the replacement lube. I want to flush out any crud that exists in the cavity before installing the new fluid. I have read that adding kerosine and running the tractor and PTO for a while and draining will do the job. I am interested as to what anyone might think of that or has any other suggestions for preparations prior to adding the pump.

Thanks,
Rod

As far as the fluid, I flushed mine out, and put in 20 wt non detergent. It is not easy to find, but is not that expensive. They still use it in some airplanes I was told. I had some so called expert tell me that the modern stuff has something in the oil that will eat the brass bushings in the old equipment. I do not know if it is true for sure, but I put in the non detergent 20 wt, and it works.
