HydroGear issue

[dheisler]

Ok, we are back in business. Installed the pump this time with no fluid, just the parts lubricated. I've been through this install process now about three times and the only for sure difference is that this time I did not fill the pump full of fluid, could that have caused my issue? Only fitting that was suspect was tight when I checked it.

Now just have to fix the high pressure line fitting, still must be slightly mis aligned.

No. Adding fluid to the Hydro did not cause your issue. Not sure how you got it to hold fluid at all..... Oil should have ran out the back output shaft bearing.

The suction line is the one that runs to the top of the unit. The line nuts aren't the only suspect items. Both the 90 deg fitting at the top, and the fitting at the bottom are o-ring type fittings. Make sure they are tight, and hopefully you installed new o-rings during one of the many times you had it out....

deisler,


Your comment, "...refilled with Hytran (meets IH specs)...", has me wondering what you used.

20 some years ago, I replaced the fluid and filter in a 1512 with "meets IH specs" fluid from the local Fleet Farm store. It allowed the hydro to free wheel down the ditch.

I inquired about it with my local Cub guru and he knew what I did after I told him the symptoms. I changed out the fluid and filter with the real stuff and all was well.

I'm not saying every Hy-Tran equivalent is bad, or that your fluid is causing your problem.
