Hey everyone,

Is anyone else out there having to pack and repack the TK twin post jacks ? We are finding they are needing to be repacked every 2 years on several elevators. Just curious. Thanks are there any long term solution s out there?

I have noticed on those it is very dependent on the installation. Were they put in with extreme care and caution as to not mar the piston or not. Spending some time with some emory cloth has done wonders for some of mine.

We have had this issue also, we started getting our packings from gorman and it made a big difference. Gorman is visibly beefier and has held up so far.

Also it is critical that the jacks are plumb.

I don't think there is anything official from TK on this, but I have experienced that on quite a few jobs that use the NZ(non zinc) oil and the yellow Parker made seals tend to brake down and literally fall apart with a couple years. All the latest seal kits from TK are a different color(orange) and possibly from different manufacture, so I'm fairly certain they had issues with the old seals they used.

Thanks for the input guys.

We packed this elevator 17 months ago. Orange packing from TK was used. 5 cars on the job. I fear they are all going to be failing soon. Sounds like I need to investigate the oil being used and I’ll look into the Gorman packing. Thanks for the info guys.

Use the Gorman packings!!!

Ordered Gorman packings this morning. Thanks guys
