Power booster

[Chevykev]

Seem to have a slight fluid leak from this on the power booster, what is it and is there a replaceable seal for it. Looks like someone's had a pipe wrench on it at some time

That is the pressure accumulator, it stores a quantity of hydraulic oil under pressure in case of pressure loss. As this is a key safety system, get it fixed asap. Part numbers are in the -24P TM. Overhaul instructions are in the -34P TM.

I saw an original NSN rebuild kit on ebay a few weeks back.

Rebuilt units are very common at your favorite parts counter.

Chapter 7-3 in the -34 TM. Please read and follow the procedure.. A special tool is needed, J26889. Must be made of gold, they want over 200 dollars for them. Looks like a shop fabrication worth a buck. https://www.autotoolworld.com/Kent-Moore-J-26889-Accumlator-Piston-Compressor_p_211177.html

This may chafe the purists, but for the same $200 you can get a remanufactured unit from O'Reilly with a lifetime warranty. Or from Rock Auto for $125 to $225. It's the same part. For those dollars, there's no way I'd go thru the hassle of having a special tool machined, buy the kit, and still have to do the labor to rebuild it. Strictly my opinion. But if you enjoy special or intricate projects, this one has the potential to be a good time.

Definitely agree with this. Mine was leaking as well so I purchased an entire remanufactured booster from rock auto. It’s pretty quick to swap out and then you can have more confidence in the entire unit

Buy a rebuilt one. Most are warranted for life. Just keep in mind to install it before you turn in the core. Sometimes not all parts are included with the rebuilt booster. Ask me how I know. I had 1 that was missing the push rod and sprag spring retainer. Returned it and had to tear another parts vehicle apart to get the push rod. Take Care. And as I always say there is more to rebuilding things then just taking it apart and replacing a few seals and gaskets. I see poor workmanship all the time. I try to practice what I preach and do the best job I can. I even hire out work I can't do myself. Money well spent. Take Care and Be Safe.
