RFI: Allied 2 ton Floor jack repair

just mho, tried just adding some fluid? if not, do so. --Loren

Had a similar problem with a 20 plus year old triolley jack just recently. I took the whole lot apart using an adjustable wrench and a vice - its no big deal, no special tools, gave it a thorough clean up with some turps and meths - amazing the amount of crud in the bore that builds up over that time period. I took the seal to the local auto repair shop (REPCO in Aus) and they had a seal off the shelf. The old seal had a definite flat spot on the bottom of it where the muck in the bore had been. I replaced the oil using some nice thick engine oil and its been working fine since.

You might try sending a contact email asking about it to Allied Tools:

My old Sears floorjack went kaput but only needed an o-ring replaced upon disassembly. Take it apart and see's whats busted, maybe you'll be lucky like me and its an off the shelf part.

Having just done a trolley jack the other day, they are pretty easy. You will need to pull the jack out of the frame - mine had 6 allen screws holding it in. There is a BIG nut on the top of the ram shroud. in my case the ram shroud was a piece of pipe which also threaded into the main body. Remove both the nut and the pipe - you will need a big spanner, a solid vice and a Stilson and rags to clean up spilt oil ;-) Go to local seal and bearing emporium and for $NZ10.58 (~$US6.60) they can match you up another one. Take the ram so they can check the size. New Zealanders can go to Seal House, East Tamaki. You may need to buy a bit of jack oil as well, although I have head of people using ATF or hydraulic oil.

Thanks, just what I needed. Although, I'd rather go to NZ for the seals than the local bearing/seal house. Really bad end of town. Best of the New Year to all. Jim

(snip) Engine oil is NOT a good "jack oil"! Try a hydraulic fluid. The stuff I use is a John Deere variety.

I repaired three jacks about 20 years ago, I found them VERY hard to take apart, I ended up at a jack repair place and had them break the threaded joint with their tools ( a LARGE vice and a 10-foot cheater on a special wrench), I had bought the repair kits from them and they were very good-natured about my chagrin from being unable to dissassemble the jack with my Sears vice and 18" pipe wrench.
