Air Entrainment and Foaming Hydraulic Fluid
Good reservoir design and use of foam inhibitors usually eliminate surface foaming. Air entrainment is a dispersion of very small air bubbles in a hydraulic fluid. Oil under low pressure absorbs approximately 10 percent air by volume.

Symptoms of Common Hydraulic Problems and Their Root Causes
Air in the hydraulic fluid makes an alarming banging or knocking noise when it compresses and decompresses, as it circulates through the system. Other symptoms include foaming of the fluid and erratic actuator movement. Aeration accelerates degradation of the fluid and causes damage to system components through loss of lubrication, overheating

• The ability of oil to resist with mixing with water is known as Demulsibility. • Low foaming tendency: • A good hydraulic fluid will not absorb air easily and will release it quickly without causing foam. • Oxidation: • Oxidation causes the oil to thicken and produces varnishes which strain the component surface. • …

Hydraulic Oil and Trans Oil change - JDcrawlers Messageboard
Sep 22, 2018 · Re: Hydraulic Oil and Trans Oil change. These have separate hydraulics and trans. The hydraulic tank is on the right hand side. IIRC, the filler cap and sight glass is on the back side of the 550 and 555. The drain will be under the tank, and above the track. The trans drain will be on the bottom of the trans case, towards the rear.

Bobcat Hydraulic fluid foaming and coming out breather cap
Nov 14, 2020 · Bobcat also stopped recommending 10W-30 motor oil in the hyd's in 2006. Most UTTF tractor fluid is 10W-30 and is approved for hydrostatic transmissions or the Bobcat oil is what should be used. If there's that much foaming, I'd think air is getting in somehow too or the fluid is low and a return line is above the fluid level causing the foaming.

What would cause Tractor Hydraulic fluid to foam? - Answers
Foam - air bubbles typically greater than 1 mm in diameter that congregate on the surface of the oil. Of these four forms, entrained air is the most problematic. Pre-filling components and proper bleeding of the hydraulic system during start-up will usually eliminate free air. Small amounts of foam are cosmetic and generally do not pose a problem.

I dunno the add package that comes with it. 10W is a SAE 10 weight or ISO 30 viscosity and 20 weight is just that, a SAE 20 weight or a ISO 68 viscosity. They are not the same. There is no such oil weight as "10w". Only oils that meet 10w spec's. They're 20 weight oils ..even hydraulic oils. 10W oil is a 10W-20.

Causes and Solutions for Foaming in Oil
Jun 30, 2011 · Up to20%cash back · Hydraulic oil will foam because the hydraulic system has a suction leak and is sucking in air. This causes the foaming. The suction hoses and clamps and fittings and orings, from the tank to the pumps need to be checked. Look for seeps where oil might leak out when unit is off and would indicate small hole in hose or loose clamp.
