Cylinder leak?

    I took off my Boss 7'6" straight blade today and I noticed some red fluid on my front bumper and then I noticed the same red fluid by the fitting at the top of the raise/ lower cylinder, on the back side of the plow which would be facing the front bumper of my truck. I am not sure what that fitting is on the cylinder, but it looks like that is where the fluid is coming from. Do I need to replace the cylinder or can I tighten that fitting? My plow is about 10 years old, and has the original hoses, fluid and cylinders. The plow is in excellent shape since I only plow my own driveway (150 feet or so, double wide).

    The upper hose only has pump pressure in it when operating the Smart Hitch. So if it's leaking a little it most likely happened as soon as you attached the plow. Clean the area up and operate the SH a few times while watching that hose/fitting and connection to see exactly what is leaking. May need nothing more than the hose snugged up as mentioned.

    I don't have the smart hitch option. The fitting that is leaking is not where the hose attatches. The fitting looks like a grease fitting and there is no hose attatched to it. Is this a fill port or some type of an air release fitting???? It is on the side of the raise/ lower cylinder that faces the front of my truck and it is very small.

    Is your plow a standard duty or super duty? If it is a standard duty, does it have the smart-hitch option? If it does not have the smart-hitch it will not have the upper hose on the lift cylinder and will just have a breather fitting. If fluid is coming out of the breather fitting your cylinder is going bad and will need to be replaced.

    Then that fitting is a breather/vent. If there's fluid coming from there the cylinder will need rebuilt or replaced.
