TYM T224
After some usage on my TYM T224 yesterday, I checked the front axle and trans/hydraulic fluid. I've seen some talk online about front axles not being able to relieve pressure and being the suspect cause of axle seal leakage. After examining the front axle and trans cap on my TYM, these caps can both easily breathe in and out. Straight up through the inside center and in/out the little rectangular notches to the outside of the black gasket seal. Those notches are somewhat protected under the outside flange of the caps to keep rainwater, etc out. Maybe they're all this way and I missed the memo? The only issue I could see is if you buried the front axle under water, you could get water in there. If you were up to the hydraulic cap, you got bigger problems to worry about. Pictured below is the standard style trans/hydraulic cap my T224 has. The front axle is the same design, but has a dipstick snapped into that oval in the center. FWIW, I still can't determine where my hydraulic fluid level is. I can't tell if the bullseye is over full or empty.
