Central Hydraulics 3 ton floor jack, rebuild kits?

[wwk68]

Having an issue with this floor jack losing height when under load. This is the only thing that I find on Lazzar's website:

2 Piece Set - O-Ring and Backup (For 16mm Pump Piston ONLY)

They do have a full seal kit for the 2 & 3/4 ton. Would this work for the 3 ton?

I have the 2.5 ton long frame jack, but the hydraulics looks the same.

I had the same issue and found the piston disintegrating. At that time I couldn't find HF replacement parts. My brother happened to be rebuilding the drum brakes on his 97 Blazer and I noticed the pistons were the same size, 7/8". If your bore is a different size, you might have to dig a little to find the matching piston.

I bought a kit, Raymold 35418 and used one of the pistons, still have a spare. I had to use a gasket punch to put a center hole in it, can't remember the size.

That piston has been in there for about 20 years and still works fine.

Hope this helps, good luck,

Jim

Thanks for the reply. Could you possibly upload a pic of the piston you used? Or, perhaps link to a pic on the web.

As an aside, anyone know when these orange/white HF jacks were sold? 90s?
