How the $%#@ do you repack this thing? Is there an easy way to repack this upside-down holeless cylinder?

When I was working for the big S, I was told you could do both sides start to finish in 4 hours... I believe D.L. Martin fabricated the jacks....they may have info. Use air to return oil from piston to tank...this will help keep oil mess in pit to a minimum.

I've also been told to allow atleast 8 hours...The last reply was info from a repair crew who had done afew...No real easy way...

An easier way is to tell your service sales people to stay away from this garbage !!!

I have repacked these hole less hydros its 8hrs repair one side if you dont have repair instructions could be a long day

Changing these packings is easy,just messy! PM me and I can give you some tips.

Keep you posted. Volunteered to do one tomorrow for fun.

no repost....I guess it wasn't that fun.

Actually not that bad. Definetly take your time. About 6 hours per side would be the norm. Mine had accumulated rust in all of the snap ring grooves. DO NOT just buy the Texacone seals. They have a complete kit that includes wipers (which turned to out be one of the hardest parts), and the most critical pieces, the "O" rings that seal the pistons to the housings. Large snap ring pliers are a must (0.095). Blowing air into the top of the cylinder from a compressor was a huge help with mess reduction. Although for some reason the bleeder plug is a metric bolt thread, not pipe thread. So use a rubber tip from an air gun.

Anyone have the procedure for this or any tips?

my question is why do companies do this crazy stuff? how much money do they save vs. holed hydro or a traction car? it seems like every big company puts this stuff out then figures out its a bad idea shortly after installation but we have to live with it forever. for whatever reason it seems like all these crazy hydro ideas come out of germany. are they trying to get back at us for something?

Amen brother!! Nothing but trouble, check my post about having to replace CRIPHNA boards due to a 1 cent resistor burning up. Have had 3 Schindler units at 3 different buildings within 2 weeks because R176 burns up and then?? Guess what no door power! Had people stuck today, so it's another $800 to replace another board....

do any body have prints for an schindler in ground piston.please ms me [email protected]

Does anyone have instructions on re-packing these jacks? They are very difficult to work on. It would be greatly appreciated, thanks.
