Ford Shock Absorber Fluid
What is everyone using to replace the Ford Shock Absorber Fluid?

Re: Ford Shock Absorber Fluid
I've topped mine off with Liquid Wrench Hydraulic Jack Oil; says it's good for hydraulic jacks and refillable shock absorbers. Has worked well so far... I think just about any hydraulic jack oil would be OK.

Re: Ford Shock Absorber Fluid
I read a article about motorcycle fork oils, ATF is rated as good in it's viscosity range, and tractor multi viscosity transmission oil had a good rating ---depending on how worn the socks are

Hi Everyone! Here's what Bill Wzorek and Andrew Falandes say...
Dangit folks, hug the ones you love. I'd like to see Bill again. https://www.fordbarn.com/forum/showp...76&postcount=6

I would gravitate toward an hydraulic oil with a viscosity that is near SAE 50 motor oil. SAE-50 motor oil is the same viscosity as SAE-90 gear oil but without the sulfuric acid/phosphoric acid based extreme pressure additives. A person may need a conversiion table for the difference between the ISO viscosity grading system and the SAE system since most hydraulic oils are now graded on the new international system. ISO-150 is very near SAE-40 and ISO-220 is very near SAE-50. Hydraulic oils would be the ideal fluid since that is what they are made for if there are any available in the higher viscosities The viscosity will vary depending on the condition of the shocks. As they wear, the clearances get larger and larger so the viscosity will have to increase to allow function. If hydraulic oils aren't available in the high viscosity ranges then straight mineral aircraft motor oils may be an alternative such as AeroShell 100. Most jack oils are about SAE-20 or ISO-46 so thay may not be thick enough. Last edited by rotorwrench; 12-25-2020 at 10:40 AM. |
