Good afternoon-
I posted this question in the "Show and Tell" forum so sorry if you have already seen it.
I recently bought a JD Straight 450 crawler dozer. One of the issues is that it has a slow leak from the front of the HLR. The leaking fluid is reddish purple, like automatic transmission fluid- it isn't 303 or Hygard, at least the color I am used to seeing.
Does anyone have some insight on what fluid this may be (like maybe the cold temp (low viscosity) Hygard is red?). I also wonder about mixing Hygard with that fluid and what problems that may cause. having said that, the crawler appears to shift OK between high, low, and reverse.
Thanks in advance.

Hi,
The low viscosity HyGard isn't red, looks like the regular stuff. So, I am thinking it has ATF in there which won't properly lubricate your trans. I'd get that out and put in what needs to be there.

I bought some oil from Orchland Farm and Home that was labelled “Premium 303”. It had a red tint but was not as dark red as transmission fluid. It defiantly wouldn’t hurt to change it.

Hi,
Nope. Never hurts to Change It All on a machine recently acquired. Other than brand-spanking-new, of course. That way you know for sure the What and the When.

Re: HLR Transmission Fluid Question
Thanks for the replies. I also found a post last night on another JD tractor website that talked about a JD-brand dye that could be added to Hygard so you could see leaks better. In any case I'm not sure what it is because it doesn't have the smell of ATF and is more purplish but also doesn't look like Hygard so probably best to change it.
Of course with the front leak I have right now it will eventually change itself if I keep running it

Hi,
ACF: Auto Changing Fluid. It is not a bug, it is a feature!
Reminds me of the really old iron, with exposed gears and an oil tank on the fender with lines running all over to drip oil. Total Loss lubrication. And water running over screens to cool. Total Loss cooling. Ah, the days of overly large, overly simple designs.
