transmission

Postby john2189 » Mon Jan 07, 2019 11:37 pm

ok if the transmission gets overfilled or filled with water from sitting outside, what would it hurt to drill a vent hole in the 1/8th pipe plug that is at the full level? then if it does get water or whatever, itll leak there instead of leaking into the brakes.

Hi,
I would park the Cub on a level surface, and remove the oil level plug every few months, and check the oil level, if you think water has gotten in the transmission.
Probably oil will run out any hole drilled in the plug, when using the Cub. The gears throw the oil inside the housing. :)

Once the water and oil separates, the oil floats on top of the water. The hole would drain out the oil and the water would remain in the transmission and fill the area from the bottom up. If using the cub regularly, the oil and water somewhat get stirred together into a blonde color mixture.
I think Hytran has some chemical properties to "absorb" some of the water and keep it suspended better than the 80/90 weight gear oil.

Is Hytran OK for the transmission?

Late Cubs called for Hy-Tran. (I'm talking about "real" caseIH Hy-Tran, not something from Walmart, Napa, some guy selling oil out of his trunk, etc.) Hy-Tran (again, the real stuff) does a good job absorbing water in transmissions, etc. The only issue is it's thinner and will leak past old seals and stuff a lot easier.

Hi,
Below is the Lubrication Table from the 1975 Cub owner's manual, it shows to use Hy-Tran fluid, or regular gear oil in the transmission, and final drives. The recommendation is in the owner's manuals back to 1959, that I saw in the list of manuals. :)

I use Hytran in my 184 and it is a thinner lubricant than 80-90wt gear oil. It may take an extra second or two for the transmission input shaft to quit spinning if the pilot or throwout bearing drags a little.

Doesn’t the numbered lowboys use the transmission for its hydraulic oil resivoir for the hydraulic system?

Yes, it does use the transmission for the hydraulic oil reservoir. It takes an awful lot of hytran!

I wouldn't drill a hole in it. As stated above oil will separate and the oil will.more leak out than water. I change mine once a year and call it good.

Lol this is true. But you get enough leaks elsewhere when over full.
