Hydroboost Systems
It's Good To Be Blown. We Prefer The New Unit Because The Spool Valve Is A Precision Tight Fit In Its Bore. 0005" Clearance. If It Doesn't Seal, The Power Is Off. If The Hydroboost Is Maintained With Clean Fluid, It Will Last A L0ng Time. You Don't Know In A Used Or Rebuilt Unit How Perfect The Spool Valve Bore Is. There Is No Way To Hone It, Sleeve It, Or Use Oversize Spools. Most Hydroboosts Are Replaced Around 150,000 Miles, Due To Leaks, But Few Have Had The Fluid Replaced In Those Miles. The H/b Doesn't Wear By It Self, But The Hardened Metal Worn Off Of The Steering Gears Floats Around The System Causing The Wear. 20 Year Old Fluid Turns Into Shellac. Not A Good Lubricant. Just Like A Transmission, It Needs Clean Fluid. Transmissions Also Have Filters. We Have An Inline Filter For The Hydroboost.we Also Use The Larger Power Piston Design. The H/b, Master, Mounting Bracket, In New Is $525.00. Rebuilt Unit, New Master, Would Be $325.00. We Prefer Our Stainless Hoses. They Have A Banjo Swivel End Swedged On One End For A Clean Look. The Hose Set Is $285.00. Warranty On A New Unit Is 1 Year, Reman Is 6 Months
